04a7085007 feat(repl): implement M12 REPL commands and session tracking 
Add comprehensive REPL commands for session management and introspection:

**Session Tracking** (`crates/core/agent/src/session.rs`):
- SessionStats: Track messages, tool calls, tokens, timing
- SessionHistory: Store conversation history and tool call records
- Auto-formatting for durations (seconds, minutes, hours)

**REPL Commands** (in interactive mode):
- `/help`        - List all available commands
- `/status`      - Show session stats (messages, tools, uptime)
- `/permissions` - Display permission mode and tool access
- `/cost`        - Show token usage and timing (free with Ollama!)
- `/history`     - View conversation history
- `/clear`       - Reset session state
- `/exit`        - Exit interactive mode gracefully

**Stats Tracking**:
- Automatic message counting
- Token estimation (chars / 4)
- Duration tracking per message
- Tool call counting (foundation for future)
- Session uptime from start

**Permission Display**:
- Shows current mode (Plan/AcceptEdits/Code)
- Lists tools by category (read-only, write, system)
- Indicates which tools are allowed/ask/deny

**UX Improvements**:
- Welcome message shows model and mode
- Clean command output with emoji indicators
- Helpful error messages for unknown commands
- Session stats persist across messages

**Example Session**:
```
🤖 Owlen Interactive Mode
Model: qwen3:8b
Mode: Plan

> /help
📖 Available Commands: [list]

> Find all Cargo.toml files
🔧 Tool call: glob...
✅ Tool result: 14 files

> /status
📊 Session Status:
  Messages: 1
  Tools: 1 calls
  Uptime: 15s

> /cost
💰 Token Usage: ~234 tokens

> /exit
👋 Goodbye!
```

Implements core M12 requirements for REPL commands and session management.
Future: Checkpointing/rewind functionality can build on this foundation.

6022aeb2b0 feat(cli): add interactive REPL mode with agent loop 
Add proper interactive mode when no prompt is provided:

**Interactive REPL Features**:
- Starts when running `cargo run` with no arguments
- Shows welcome message with model name
- Prompts with `> ` for user input
- Each input runs through the full agent loop with tools
- Continues until Ctrl+C or EOF
- Displays tool calls and results in real-time

**Changes**:
- Detect empty prompt and enter interactive loop
- Use stdin.lines() for reading user input
- Call agent_core::run_agent_loop for each message
- Handle errors gracefully and continue
- Clean up unused imports

**Usage**:
```bash
# Interactive mode
cargo run

# Single prompt mode
cargo run -- --print "Find all Cargo.toml files"

# Tool subcommands
cargo run -- glob "**/*.rs"
```

Example session:
```
🤖 Owlen Interactive Mode
Model: qwen3:8b

> Find all markdown files
🔧 Tool call: glob with args: {"pattern":"**/*.md"}
✅ Tool result: ./README.md ./CLAUDE.md ./AGENTS.md
...

> exit
```

e77e33ce2f feat(agent): implement Agent Orchestrator with LLM tool calling 
Add complete agent orchestration system that enables LLM to call tools:

**Core Agent System** (`crates/core/agent`):
- Agent execution loop with tool call/result cycle
- Tool definitions in Ollama-compatible format (6 tools)
- Tool execution with permission checking
- Multi-iteration support with max iteration safety

**Tool Definitions**:
- read: Read file contents
- glob: Find files by pattern
- grep: Search for patterns in files
- write: Write content to files
- edit: Edit files with find/replace
- bash: Execute bash commands

**Ollama Integration Updates**:
- Extended ChatMessage to support tool_calls
- Added Tool, ToolCall, ToolFunction types
- Updated chat_stream to accept tools parameter
- Made tool call fields optional for Ollama compatibility

**CLI Integration**:
- Wired agent loop into all output formats (Text, JSON, StreamJSON)
- Tool calls displayed with 🔧 icon, results with ✅
- Replaced simple chat with agent orchestrator

**Permission Integration**:
- All tool executions check permissions before running
- Respects plan/acceptEdits/code modes
- Returns clear error messages for denied operations

**Example**:
User: "Find all Cargo.toml files in the workspace"
LLM: Calls glob("**/Cargo.toml")
Agent: Executes and returns 14 files
LLM: Formats human-readable response

This transforms owlen from a passive chatbot into an active agent that
can autonomously use tools to accomplish user goals.

Tested with: qwen3:8b successfully calling glob tool

c9e2f9bae6 fix(core,tui): complete remaining P1 critical fixes 
This commit addresses the final 3 P1 high-priority issues from
project-analysis.md, improving resource management and stability.

Changes:

1. **Pin ollama-rs to exact version (P1)**
   - Updated owlen-core/Cargo.toml: ollama-rs "0.3" -> "=0.3.2"
   - Prevents silent breaking changes from 0.x version updates
   - Follows best practice for unstable dependency pinning

2. **Replace unbounded channels with bounded (P1 Critical)**
   - AppMessage channel: unbounded -> bounded(256)
   - AppEvent channel: unbounded -> bounded(64)
   - Updated 8 files across owlen-tui with proper send strategies:
     * Async contexts: .send().await (natural backpressure)
     * Sync contexts: .try_send() (fail-fast for responsiveness)
   - Prevents OOM on systems with <4GB RAM during rapid LLM responses
   - Research-backed capacity selection based on Tokio best practices
   - Impact: Eliminates unbounded memory growth under sustained load

3. **Implement health check rate limiting with TTL cache (P1)**
   - Added 30-second TTL cache to ProviderManager::refresh_health()
   - Reduces provider load from 60 checks/min to ~2 checks/min (30x reduction)
   - Added configurable health_check_ttl_secs to GeneralSettings
   - Thread-safe implementation using RwLock<Option<Instant>>
   - Added force_refresh_health() escape hatch for immediate updates
   - Impact: 83% cache hit rate with default 5s TUI polling
   - New test: health_check_cache_reduces_actual_checks

4. **Rust 2024 let-chain cleanup**
   - Applied let-chain pattern to health check cache logic
   - Fixes clippy::collapsible_if warning in manager.rs:174

Testing:
- ✅ All unit tests pass (owlen-core: 40, owlen-tui: 53)
- ✅ Full build successful in 10.42s
- ✅ Zero clippy warnings with -D warnings
- ✅ Integration tests verify bounded channel backpressure
- ✅ Cache tests confirm 30x load reduction

Performance Impact:
- Memory: Bounded channels prevent unbounded growth
- Latency: Natural backpressure maintains streaming integrity
- Provider Load: 30x reduction in health check frequency
- Responsiveness: Fail-fast semantics keep UI responsive

Files Modified:
- crates/owlen-core/Cargo.toml
- crates/owlen-core/src/config.rs
- crates/owlen-core/src/provider/manager.rs
- crates/owlen-core/tests/provider_manager_edge_cases.rs

7b87459a72 chore: update dependencies and fix tree-sitter compatibility 
Update dependencies via cargo update to latest compatible versions:
- sqlx: 0.8.0 → 0.8.6 (bug fixes and improvements)
- libsqlite3-sys: 0.28.0 → 0.30.1
- webpki-roots: 0.25.4 → 0.26.11 (TLS security updates)
- hashlink: 0.9.1 → 0.10.0
- serde_json: updated to 1.0.145

Fix tree-sitter version mismatch:
- Update owlen-tui dependency to tree-sitter 0.25 (from 0.20)
- Adapt API call: set_language() now requires &Language reference
- Location: crates/owlen-tui/src/state/search.rs:715

Security audit results (cargo audit):
- 1 low-impact advisory in sqlx-mysql (not used - we use SQLite)
- 3 unmaintained warnings in test dependencies (acceptable)
- No critical vulnerabilities in production dependencies

Testing:
- ✅ cargo build --all: Success
- ✅ cargo test --all: 171+ tests pass, 0 failures
- ✅ cargo clippy: Clean
- ✅ cargo audit: No critical issues

4935a64a13 refactor: complete Rust 2024 let-chain migration 
Migrate all remaining collapsible_if patterns to Rust 2024 let-chain
syntax across the entire codebase. This modernizes conditional logic
by replacing nested if statements with single-level expressions using
the && operator with let patterns.

Changes:
- storage.rs: 2 let-chain conversions (database dir creation, legacy archiving)
- session.rs: 3 let-chain conversions (empty content check, ledger dir creation, consent flow)
- ollama.rs: 8 let-chain conversions (socket parsing, cloud validation, model caching, capabilities)
- main.rs: 2 let-chain conversions (API key validation, provider enablement)
- owlen-tui: ~50 let-chain conversions across app/mod.rs, chat_app.rs, ui.rs, highlight.rs, and state modules

Test fixes:
- prompt_server.rs: Add missing .await on async RemoteMcpClient::new_with_config
- presets.rs, prompt_server.rs: Add missing rpc_timeout_secs field to McpServerConfig
- file_write.rs: Update error assertion to accept new "escapes workspace boundary" message

Verification:
- cargo build --all: ✅ succeeds
- cargo clippy --all -- -D clippy::collapsible_if: ✅ zero warnings
- cargo test --all: ✅ 109+ tests pass

Net result: -46 lines of code, improved readability and maintainability.

0728262a9e fix(core,mcp,security)!: resolve critical P0/P1 issues 
BREAKING CHANGES:
- owlen-core no longer depends on ratatui/crossterm
- RemoteMcpClient constructors are now async
- MCP path validation is stricter (security hardening)

This commit resolves three critical issues identified in project analysis:

## P0-1: Extract TUI dependencies from owlen-core

Create owlen-ui-common crate to hold UI-agnostic color and theme
abstractions, removing architectural boundary violation.

Changes:
- Create new owlen-ui-common crate with abstract Color enum
- Move theme.rs from owlen-core to owlen-ui-common
- Define Color with Rgb and Named variants (no ratatui dependency)
- Create color conversion layer in owlen-tui (color_convert.rs)
- Update 35+ color usages with conversion wrappers
- Remove ratatui/crossterm from owlen-core dependencies

Benefits:
- owlen-core usable in headless/CLI contexts
- Enables future GUI frontends
- Reduces binary size for core library consumers

## P0-2: Fix blocking WebSocket connections

Convert RemoteMcpClient constructors to async, eliminating runtime
blocking that froze TUI for 30+ seconds on slow connections.

Changes:
- Make new_with_runtime(), new_with_config(), new() async
- Remove block_in_place wrappers for I/O operations
- Add 30-second connection timeout with tokio::time::timeout
- Update 15+ call sites across 10 files to await constructors
- Convert 4 test functions to #[tokio::test]

Benefits:
- TUI remains responsive during WebSocket connections
- Proper async I/O follows Rust best practices
- No more indefinite hangs

## P1-1: Secure path traversal vulnerabilities

Implement comprehensive path validation with 7 defense layers to
prevent file access outside workspace boundaries.

Changes:
- Create validate_safe_path() with multi-layer security:
  * URL decoding (prevents %2E%2E bypasses)
  * Absolute path rejection
  * Null byte protection
  * Windows-specific checks (UNC/device paths)
  * Lexical path cleaning (removes .. components)
  * Symlink resolution via canonicalization
  * Boundary verification with starts_with check
- Update 4 MCP resource functions (get/list/write/delete)
- Add 11 comprehensive security tests

Benefits:
- Blocks URL-encoded, absolute, UNC path attacks
- Prevents null byte injection
- Stops symlink escape attempts
- Cross-platform security (Windows/Linux/macOS)

## Test Results

- owlen-core: 109/109 tests pass (100%)
- owlen-tui: 52/53 tests pass (98%, 1 pre-existing failure)
- owlen-providers: 2/2 tests pass (100%)
- Build: cargo build --all succeeds

## Verification

- ✓ cargo tree -p owlen-core shows no TUI dependencies
- ✓ No block_in_place calls remain in MCP I/O code
- ✓ All 11 security tests pass

Fixes: #P0-1, #P0-2, #P1-1

c7b7fe98ec feat(session): implement streaming state with text delta and tool‑call diff handling 
- Introduce `StreamingMessageState` to track full text, last tool calls, and completion.
- Add `StreamDiff`, `TextDelta`, and `TextDeltaKind` for describing incremental changes.
- SessionController now maintains a `stream_states` map keyed by response IDs.
- `apply_stream_chunk` uses the new state to emit append/replace text deltas and tool‑call updates, handling final chunks and cleanup.
- `Conversation` gains `set_stream_content` to replace streaming content and manage metadata.
- Ensure stream state is cleared on cancel, conversation reset, and controller clear.

# AGENTS.md - AI Agent Instructions for Owlen Development
This document provides comprehensive context and guidelines for AI agents (Claude, GPT-4, etc.) working on the Owlen codebase.
## Project Overview
**Owlen** is a local-first, terminal-based AI assistant built in Rust using the Ratatui TUI framework. It implements a Model Context Protocol (MCP) architecture for modular tool execution and supports both local (Ollama) and cloud LLM providers.
**Core Philosophy:**
- **Local-first**: Prioritize local LLMs (Ollama) with cloud as fallback
- **Privacy-focused**: No telemetry, user data stays on device
- **MCP-native**: All operations through MCP servers for modularity
- **Terminal-native**: Vim-style modal interaction in a beautiful TUI
**Current Status:** v1.0 - MCP-only architecture (Phase 10 complete)
## Architecture
### Project Structure

```
### Key Technologies
- **Language**: Rust 1.83+
- **TUI**: Ratatui with Crossterm backend
- **Async Runtime**: Tokio
- **Config**: TOML (serde)
- **HTTP Client**: reqwest
- **LLM Providers**: Ollama (primary), with extensibility for OpenAI/Anthropic
- **Protocol**: JSON-RPC 2.0 over STDIO/HTTP/WebSocket
## Current Features (v1.0)
### Core Capabilities
1. **MCP Architecture** (Phase 3-10 complete)
- All LLM interactions via MCP servers
- Local and remote MCP client support
- STDIO, HTTP, WebSocket transports
- Automatic failover with health checks
2. **Provider System**
- Ollama (local and cloud)
- Configurable per-provider settings
- API key management with env variable expansion
- Model switching via TUI (`:m` command)
3. **Agentic Loop** (ReAct pattern)
- THOUGHT → ACTION → OBSERVATION cycle
- Tool discovery and execution
- Configurable iteration limits
- Emergency stop (Ctrl+C)
4. **Mode System**
- Chat mode: Limited tool availability
- Code mode: Full tool access
- Tool filtering by mode
- Runtime mode switching
5. **Session Management**
- Auto-save conversations
- Session persistence with encryption
- Description generation
- Session timeout management
6. **Security**
- Docker sandboxing for code execution
- Tool whitelisting
- Permission prompts for dangerous operations
- Network isolation options
### TUI Features
- Vim-style modal editing (Normal, Insert, Visual, Command modes)
- Multi-panel layout (conversation, status, input)
- Syntax highlighting for code blocks
- Theme system (10+ built-in themes)
- Scrollback history (configurable limit)
- Word wrap and visual selection
## Development Guidelines
### Code Style
1. **Rust Best Practices**
- Use `rustfmt` (pre-commit hook enforced)
- Run `cargo clippy` before commits
- Prefer `Result` over `panic!` for errors
- Document public APIs with `///` comments
2. **Error Handling**
- Use `owlen_core::Error` enum for all errors
- Chain errors with context (`.map_err(|e| Error::X(format!(...)))`)
- Never unwrap in library code (tests OK)
3. **Async Patterns**
- All I/O operations must be async
- Use `tokio::spawn` for background tasks
- Prefer `tokio::sync::mpsc` for channels
- Always set timeouts for network operations
4. **Testing**
- Unit tests in same file (`#[cfg(test)] mod tests`)
- Use mock implementations from `test_utils` modules
- Integration tests in `crates/*/tests/`

4. Keep changes atomic and focused
**When creating new files:**
1. Check `crates/owlen-core/src/` for similar modules
2. Follow existing module structure
3. Add to `lib.rs` with appropriate visibility
4. Document module purpose with `//!` header

// Setup
let provider = MockProvider::new();
// Execute
let result = provider.chat(request).await;
// Assert
assert!(result.is_ok());
}
}
```
### Running Tests
```bash
cargo test --all # All tests
cargo test --lib -p owlen-core # Core library tests
cargo test --test integration # Integration tests
```
## Documentation Standards
### Code Documentation
1. **Module-level** (`//!` at top of file):
```rust
//! Brief module description
//!
//! Detailed explanation of module purpose,
//! key types, and usage examples.
```
2. **Public APIs** (`///` above items):
```rust
/// Brief description
///
/// # Arguments
/// * `arg1` - Description
///
/// # Returns
/// Description of return value
///
/// # Errors
/// When this function returns an error
///
/// # Example
/// ```
/// let result = function(arg);
/// ```
pub fn function(arg: Type) -> Result<Output> {
// implementation
}
```
3. **Private items**: Optional, use for complex logic
### User Documentation
Location: `docs/` directory
Files to maintain:
- `architecture.md` - System design
- `configuration.md` - Config reference
- `migration-guide.md` - Version upgrades
- `troubleshooting.md` - Common issues
- `provider-implementation.md` - Adding providers
- `faq.md` - Frequently asked questions
## Git Workflow
### Branch Strategy
- `main` - stable releases only
- `dev` - active development (default)
- `feature/*` - new features
- `fix/*` - bug fixes
- `docs/*` - documentation only
### Commit Messages
Follow conventional commits:
```
type(scope): brief description
Detailed explanation of changes.
Breaking changes, if any.
🤖 Generated with [Claude Code](https://claude.com/claude-code)
Co-Authored-By: Claude <noreply@anthropic.com>
```
Types: `feat`, `fix`, `docs`, `refactor`, `test`, `chore`
### Pre-commit Hooks
Automatically run:
- `cargo fmt` (formatting)
- `cargo check` (compilation)
- `cargo clippy` (linting)
- YAML/TOML validation
- Trailing whitespace removal
## Performance Guidelines
### Optimization Priorities
1. **Startup time**: < 500ms cold start
2. **First token latency**: < 2s for local models
3. **Memory usage**: < 100MB base, < 500MB with conversation
4. **Responsiveness**: TUI redraws < 16ms (60 FPS)
### Profiling
```bash
cargo build --release --features profiling
valgrind --tool=callgrind target/release/owlen
kcachegrind callgrind.out.*
```
### Async Performance
- Avoid blocking in async contexts
- Use `tokio::spawn` for CPU-intensive work
- Set timeouts on all network operations
- Cancel tasks on shutdown
## Security Considerations
### Threat Model
**Trusted:**
- User's local machine
- User-installed Ollama models
- User configuration files
**Untrusted:**
- MCP server responses
- Web search results
- Code execution output
- Cloud LLM responses
### Security Measures
1. **Input Validation**
- Sanitize all MCP tool arguments
- Validate JSON schemas strictly
- Escape shell commands
2. **Sandboxing**
- Docker for code execution
- Network isolation
- Filesystem restrictions
3. **Secrets Management**
- Never log API keys
- Use environment variables
- Encrypt sensitive config fields
4. **Dependency Auditing**
```bash
cargo audit
cargo deny check
```
## Debugging Tips
### Enable Debug Logging
```bash
OWLEN_DEBUG_OLLAMA=1 owlen # Ollama requests
RUST_LOG=debug owlen # All debug logs
RUST_BACKTRACE=1 owlen # Stack traces
```
### Common Issues
1. **Timeout on Ollama**
- Check `ollama ps` for loaded models
- Increase timeout in config
- Restart Ollama service
2. **MCP Server Not Found**
- Verify `mcp_servers` config
- Check server binary exists
- Test server manually with STDIO
3. **TUI Rendering Issues**
- Test in different terminals
- Check terminal size (`tput cols; tput lines`)
- Verify theme compatibility
## Contributing

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [Unreleased]
### Added
- Comprehensive documentation suite including guides for architecture, configuration, testing, and more.
- Rustdoc examples for core components like `Provider` and `SessionController`.
- Module-level documentation for `owlen-tui`.
- Provider integration tests (`crates/owlen-providers/tests`) covering registration, routing, and health status handling for the new `ProviderManager`.
- TUI message and generation tests that exercise the non-blocking event loop, background worker, and message dispatch.
- Ollama integration can now talk to Ollama Cloud when an API key is configured.
- Ollama provider will also read `OLLAMA_API_KEY` / `OLLAMA_CLOUD_API_KEY` environment variables when no key is stored in the config.
- `owlen config doctor`, `owlen config path`, and `owlen upgrade` CLI commands to automate migrations and surface manual update steps.
- Startup provider health check with actionable hints when Ollama or remote MCP servers are unavailable.
- `dev/check-windows.sh` helper script for on-demand Windows cross-checks.
- Global F1 keybinding for the in-app help overlay and a clearer status hint on launch.
- Automatic fallback to the new `ansi_basic` theme when the active terminal only advertises 16-color support.
- Offline provider shim that keeps the TUI usable while primary providers are unreachable and communicates recovery steps inline.
- `owlen cloud` subcommands (`setup`, `status`, `models`, `logout`) for managing Ollama Cloud credentials without hand-editing config files.
- Tabbed model selector that separates local and cloud providers, including cloud indicators in the UI.
- Footer status line includes provider connectivity/credential summaries (e.g., cloud auth failures, missing API keys).
- Secure credential vault integration for Ollama Cloud API keys when `privacy.encrypt_local_data = true`.
- Input panel respects a new `ui.input_max_rows` setting so long prompts expand predictably before scrolling kicks in.
- Command palette offers fuzzy `:model` filtering and `:provider` completions for fast switching.
- Message rendering caches wrapped lines and throttles streaming redraws to keep the TUI responsive on long sessions.
- Model picker badges now inspect provider capabilities so vision/audio/thinking models surface the correct icons even when descriptions are sparse.
- Chat history honors `ui.scrollback_lines`, trimming older rows to keep the TUI responsive and surfacing a "↓ New messages" badge whenever updates land off-screen.
### Changed
- The main `README.md` has been updated to be more concise and link to the new documentation.
- Default configuration now pre-populates both `providers.ollama` and `providers.ollama-cloud` entries so switching between local and cloud backends is a single setting change.
- `McpMode` support was restored with explicit validation; `remote_only`, `remote_preferred`, and `local_only` now behave predictably.
- Configuration loading performs structural validation and fails fast on missing default providers or invalid MCP definitions.
- Ollama provider error handling now distinguishes timeouts, missing models, and authentication failures.
- `owlen` warns when the active terminal likely lacks 256-color support.
- `config.toml` now carries a schema version (`1.2.0`) and is migrated automatically; deprecated keys such as `agent.max_tool_calls` trigger warnings instead of hard failures.
- Model selector navigation (Tab/Shift-Tab) now switches between local and cloud tabs while preserving selection state.
- Header displays the active model together with its provider (e.g., `Model (Provider)`), improving clarity when swapping backends.
- Documentation refreshed to cover the message handler architecture, the background health worker, multi-provider configuration, and the new provider onboarding checklist.

Following these guidelines helps to communicate that you respect the time of the developers managing and developing this open source project. In return, they should reciprocate that respect in addressing your issue, assessing changes, and helping you finalize your pull requests.
## Code of Conduct
This project and everyone participating in it is governed by the [Owlen Code of Conduct](CODE_OF_CONDUCT.md). By participating, you are expected to uphold this code. Please report unacceptable behavior.
## How Can I Contribute?
### Repository map
Need a quick orientation before diving in? Start with the curated [repo map](docs/repo-map.md) for a two-level directory overview. If you move folders around, regenerate it with `scripts/gen-repo-map.sh`.
### Reporting Bugs
This is one of the most helpful ways you can contribute. Before creating a bug report, please check a few things:
1. **Check the [troubleshooting guide](docs/troubleshooting.md).** Your issue might be a common one with a known solution.
2. **Search the existing issues.** It's possible someone has already reported the same bug. If so, add a comment to the existing issue instead of creating a new one.
When you are creating a bug report, please include as many details as possible. Fill out the required template, the information it asks for helps us resolve issues faster.
### Suggesting Enhancements
If you have an idea for a new feature or an improvement to an existing one, we'd love to hear about it. Please provide as much context as you can about what you're trying to achieve.
### Your First Code Contribution
Unsure where to begin contributing to Owlen? You can start by looking through `good first issue` and `help wanted` issues.
### Pull Requests
The process for submitting a pull request is as follows:
1. **Fork the repository** and create your branch from `main`.
2. **Set up pre-commit hooks** (see [Development Setup](#development-setup) above). This will automatically format and lint your code.
3. **Make your changes.**
4. **Run the tests.**
- `cargo test --all`
5. **Commit your changes.** The pre-commit hooks will automatically run `cargo fmt`, `cargo check`, and `cargo clippy`. If you need to bypass the hooks (not recommended), use `git commit --no-verify`.
6. **Add a clear, concise commit message.** We follow the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) specification.
7. **Push to your fork** and submit a pull request to Owlen's `main` branch.
8. **Include a clear description** of the problem and solution. Include the relevant issue number if applicable.
9. **Declare AI assistance.** If any part of the patch was generated with an AI tool (e.g., ChatGPT, Claude Code), call that out in the PR description. A human maintainer must review and approve AI-assisted changes before merge.
## Development Setup
To get started with the codebase, you'll need to have Rust installed. Then, you can clone the repository and build the project:
```sh
git clone https://github.com/Owlibou/owlen.git
cd owlen
cargo build
```
### Pre-commit Hooks
We use [pre-commit](https://pre-commit.com/) to automatically run formatting and linting checks before each commit. This helps maintain code quality and consistency.
**Install pre-commit:**
```sh
# Arch Linux
sudo pacman -S pre-commit
# Other Linux/macOS
pip install pre-commit
# Verify installation
pre-commit --version
```
**Setup the hooks:**
```sh
cd owlen
pre-commit install
```
Once installed, the hooks will automatically run on every commit. You can also run them manually:
```sh
# Run on all files
pre-commit run --all-files
# Run on staged files only
pre-commit run
```
The pre-commit hooks will check:
- Code formatting (`cargo fmt`)
- Compilation (`cargo check`)
- Linting (`cargo clippy --all-features`)
- General file hygiene (trailing whitespace, EOF newlines, etc.)
## Coding Style
- We use `cargo fmt` for automated code formatting. Please run it before committing your changes.
- We use `cargo clippy` for linting. Your code should be free of any clippy warnings.
## Commit Message Conventions
We use [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) for our commit messages. This allows for automated changelog generation and makes the project history easier to read.
The basic format is:
```
<type>[optional scope]: <description>
[optional body]
[optional footer(s)]
```
**Types:** `feat`, `fix`, `docs`, `style`, `refactor`, `test`, `chore`, `build`, `ci`.
**Example:**
```
feat(provider): add support for Gemini Pro
```
Thank you for your contribution!

GNU AFFERO GENERAL PUBLIC LICENSE
Version 3, 19 November 2007
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU Affero General Public License is a free, copyleft license for
software and other kinds of works, specifically designed to ensure
cooperation with the community in the case of network server software.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
our General Public Licenses are intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
Developers that use our General Public Licenses protect your rights
with two steps: (1) assert copyright on the software, and (2) offer
you this License which gives you legal permission to copy, distribute
and/or modify the software.
A secondary benefit of defending all users' freedom is that
improvements made in alternate versions of the program, if they
receive widespread use, become available for other developers to
incorporate. Many developers of free software are heartened and
encouraged by the resulting cooperation. However, in the case of
software used on network servers, this result may fail to come about.
The GNU General Public License permits making a modified version and
letting the public access it on a server without ever releasing its
source code to the public.
The GNU Affero General Public License is designed specifically to
ensure that, in such cases, the modified source code becomes available
to the community. It requires the operator of a network server to
provide the source code of the modified version running there to the
users of that server. Therefore, public use of a modified version, on
a publicly accessible server, gives the public access to the source
code of the modified version.
An older license, called the Affero General Public License and
published by Affero, was designed to accomplish similar goals. This is
a different license, not a version of the Affero GPL, but Affero has
released a new version of the Affero GPL which permits relicensing under
this license.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU Affero General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Remote Network Interaction; Use with the GNU General Public License.
Notwithstanding any other provision of this License, if you modify the
Program, your modified version must prominently offer all users
interacting with it remotely through a computer network (if your version
supports such interaction) an opportunity to receive the Corresponding
Source of your version by providing access to the Corresponding Source
from a network server at no charge, through some standard or customary
means of facilitating copying of software. This Corresponding Source
shall include the Corresponding Source for any work covered by version 3
of the GNU General Public License that is incorporated pursuant to the
following paragraph.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the work with which it is combined will remain governed by version
3 of the GNU General Public License.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU Affero General Public License from time to time. Such new versions
will be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU Affero General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU Affero General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU Affero General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU Affero General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU Affero General Public License for more details.
You should have received a copy of the GNU Affero General Public License
along with this program. If not, see <https://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If your software can interact with users remotely through a computer
network, you should also make sure that it provides a way for users to
get its source. For example, if your program is a web application, its
interface could display a "Source" link that leads users to an archive
of the code. There are many ways you could offer source, and different
solutions will be better for different programs; see section 13 for the
specific requirements.
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU AGPL, see
<https://www.gnu.org/licenses/>.

# OWLEN
> Terminal-native assistant for running local language models with a comfortable TUI.
![Status](https://img.shields.io/badge/status-alpha-yellow)
![Version](https://img.shields.io/badge/version-0.1.11-blue)
![Rust](https://img.shields.io/badge/made_with-Rust-ffc832?logo=rust&logoColor=white)
![License](https://img.shields.io/badge/license-AGPL--3.0-blue)
## What Is OWLEN?
OWLEN is a Rust-powered, terminal-first interface for interacting with local and cloud
language models. It provides a responsive chat workflow that now routes through a
multi-provider manager—handling local Ollama, Ollama Cloud, and future MCP-backed providers—
with a focus on developer productivity, vim-style navigation, and seamless session
management—all without leaving your terminal.
## Alpha Status
This project is currently in **alpha** and under active development. Core features are functional, but expect occasional bugs and breaking changes. Feedback, bug reports, and contributions are very welcome!
## Screenshots
![OWLEN TUI Layout](images/layout.png)
The OWLEN interface features a clean, multi-panel layout with vim-inspired navigation. See more screenshots in the [`images/`](images/) directory.
## Features
- **Vim-style Navigation**: Normal, editing, visual, and command modes.
- **Streaming Responses**: Real-time token streaming from Ollama.
- **Advanced Text Editing**: Multi-line input, history, and clipboard support.
- **Session Management**: Save, load, and manage conversations.
- **Code Side Panel**: Switch to code mode (`:mode code`) and open files inline with `:open <path>` for LLM-assisted coding.
- **Theming System**: 10 built-in themes and support for custom themes.
- **Modular Architecture**: Extensible provider system orchestrated by the new `ProviderManager`, ready for additional MCP-backed providers.
- **Dual-Source Model Picker**: Merge local and cloud catalogues with real-time availability badges powered by the background health worker.
- **Non-Blocking UI Loop**: Asynchronous generation tasks and provider health checks run off-thread, keeping the TUI responsive even while streaming long replies.
- **Guided Setup**: `owlen config doctor` upgrades legacy configs and verifies your environment in seconds.
## Security & Privacy
Owlen is designed to keep data local by default while still allowing controlled access to remote tooling.
- **Local-first execution**: All LLM calls flow through the bundled MCP LLM server which talks to a local Ollama instance. If the server is unreachable, Owlen stays usable in “offline mode” and surfaces clear recovery instructions.
- **Sandboxed tooling**: Code execution runs in Docker according to the MCP Code Server settings, and future releases will extend this to other OS-level sandboxes (`sandbox-exec` on macOS, Windows job objects).
- **Session storage**: Conversations are stored under the platform data directory and can be encrypted at rest. Set `privacy.encrypt_local_data = true` in `config.toml` to enable AES-GCM storage protected by a user-supplied passphrase.
- **Network access**: No telemetry is sent. The only outbound requests occur when you explicitly enable remote tooling (e.g., web search) or configure a cloud LLM provider. Each tool is opt-in via `privacy` and `tools` configuration sections.
- **Config migrations**: Every saved `config.toml` carries a schema version and is upgraded automatically; deprecated keys trigger warnings so security-related settings are not silently ignored.
## Getting Started
### Prerequisites
- Rust 1.75+ and Cargo.
- A running Ollama instance.
- A terminal that supports 256 colors.
### Installation
Pick the option that matches your platform and appetite for source builds:
| Platform | Package / Command | Notes |
| --- | --- | --- |
| Arch Linux | `yay -S owlen-git` | Builds from the latest `dev` branch via AUR. |
| Other Linux | `cargo install --path crates/owlen-cli --locked --force` | Requires Rust 1.75+ and a running Ollama daemon. |
| macOS | `cargo install --path crates/owlen-cli --locked --force` | macOS 12+ tested. Install Ollama separately (`brew install ollama`). The binary links against the system OpenSSL – ensure Command Line Tools are installed. |
| Windows (experimental) | `cargo install --path crates/owlen-cli --locked --force` | Enable the GNU toolchain (`rustup target add x86_64-pc-windows-gnu`) and install Ollama for Windows preview builds. Some optional tools (e.g., Docker-based code execution) are currently disabled. |
If you prefer containerised builds, use the provided `Dockerfile` as a base image and copy out `target/release/owlen`.
Run the helper scripts to sanity-check platform coverage:
```bash
# Windows compatibility smoke test (GNU toolchain)
scripts/check-windows.sh
# Reproduce CI packaging locally (choose a target from .woodpecker.yml)
dev/local_build.sh x86_64-unknown-linux-gnu
```
> **Tip (macOS):** On the first launch macOS Gatekeeper may quarantine the binary. Clear the attribute (`xattr -d com.apple.quarantine $(which owlen)`) or build from source locally to avoid notarisation prompts.
### Running OWLEN
Make sure Ollama is running, then launch the application:
```bash
owlen
```
If you built from source without installing, you can run it with:
```bash
./target/release/owlen
```
### Updating
Owlen does not auto-update. Run `owlen upgrade` at any time to print the recommended manual steps (pull the repository and reinstall with `cargo install --path crates/owlen-cli --force`). Arch Linux users can update via the `owlen-git` AUR package.
## Using the TUI
OWLEN uses a modal, vim-inspired interface. Press `F1` (available from any mode) or `?` in Normal mode to view the help screen with all keybindings.
- **Normal Mode**: Navigate with `h/j/k/l`, `w/b`, `gg/G`.
- **Editing Mode**: Enter with `i` or `a`. Send messages with `Enter`.
- **Command Mode**: Enter with `:`. Access commands like `:quit`, `:w`, `:session save`, `:theme`.
- **Quick Exit**: Press `Ctrl+C` twice in Normal mode to quit quickly (first press still cancels active generations).
- **Tutorial Command**: Type `:tutorial` any time for a quick summary of the most important keybindings.
- **MCP Slash Commands**: Owlen auto-registers zero-argument MCP tools as slash commands—type `/mcp__github__list_prs` (for example) to pull remote context directly into the chat log.
Model discovery commands worth remembering:
- `:models --local` or `:models --cloud` jump directly to the corresponding section in the picker.
- `:cloud setup [--force-cloud-base-url]` stores your cloud API key without clobbering an existing local base URL (unless you opt in with the flag).
When a catalogue is unreachable, Owlen now tags the picker with `Local unavailable` / `Cloud unavailable` so you can recover without guessing.

## Configuration
OWLEN stores its configuration in the standard platform-specific config directory:
| Platform | Location |
|----------|----------|
| Linux | `~/.config/owlen/config.toml` |
| macOS | `~/Library/Application Support/owlen/config.toml` |
| Windows | `%APPDATA%\owlen\config.toml` |
Use `owlen config path` to print the exact location on your machine and `owlen config doctor` to migrate a legacy config automatically.
You can also add custom themes alongside the config directory (e.g., `~/.config/owlen/themes/`).
See the [themes/README.md](themes/README.md) for more details on theming.
## Testing
Owlen uses standard Rust tooling for verification. Run the full test suite with:
```bash
cargo test
```
Unit tests cover the command palette state machine, agent response parsing, and key MCP abstractions. Formatting and lint checks can be run with `cargo fmt --all` and `cargo clippy` respectively.
## Roadmap
Upcoming milestones focus on feature parity with modern code assistants while keeping Owlen local-first:
1. **Phase 11 – MCP client enhancements**: `owlen mcp add/list/remove`, resource references (`@github:issue://123`), and MCP prompt slash commands.
2. **Phase 12 – Approval & sandboxing**: Three-tier approval modes plus platform-specific sandboxes (Docker, `sandbox-exec`, Windows job objects).
3. **Phase 13 – Project documentation system**: Automatic `OWLEN.md` generation, contextual updates, and nested project support.
4. **Phase 15 – Provider expansion**: OpenAI, Anthropic, and other cloud providers layered onto the existing Ollama-first architecture.
See `AGENTS.md` for the long-form roadmap and design notes.

# Security Policy
## Supported Versions
We are currently in a pre-release phase, so only the latest version is actively supported. As we move towards a 1.0 release, this policy will be updated with specific version support.
| Version | Supported |
| ------- | ------------------ |
| < 1.0 | :white_check_mark: |
## Reporting a Vulnerability
The Owlen team and community take all security vulnerabilities seriously. Thank you for improving the security of our project. We appreciate your efforts and responsible disclosure and will make every effort to acknowledge your contributions.
To report a security vulnerability, please email the project lead at [security@owlibou.com](mailto:security@owlibou.com) with a detailed description of the issue, the steps to reproduce it, and any affected versions.
You will receive a response from us within 48 hours. If the issue is confirmed, we will release a patch as soon as possible, depending on the complexity of the issue.
Please do not report security vulnerabilities through public GitHub issues.
## Design Overview
Owlen ships with a local-first architecture:
- **Process isolation** – The TUI speaks to language models through a separate MCP LLM server. Tool execution (code, web, filesystem) occurs in dedicated MCP processes so a crash or hang cannot take down the UI.
- **Sandboxing** – The MCP Code Server executes snippets in Docker containers. Upcoming releases will extend this to platform sandboxes (`sandbox-exec` on macOS, Windows job objects) as described in our roadmap.
- **Network posture** – No telemetry is emitted. The application only reaches the network when a user explicitly enables remote tools (web search, remote MCP servers) or configures cloud providers. All tools require allow-listing in `config.toml`.
## Data Handling
- **Sessions** – Conversations are stored in the user’s data directory (`~/.local/share/owlen` on Linux, equivalent paths on macOS/Windows). Enable `privacy.encrypt_local_data = true` to wrap the session store in AES-GCM encryption protected by a passphrase (`OWLEN_MASTER_PASSWORD` or an interactive prompt).
- **Credentials** – API tokens are resolved from the config file or environment variables at runtime and are never written to logs.
- **Remote calls** – When remote search or cloud LLM tooling is on, only the minimum payload (prompt, tool arguments) is sent. All outbound requests go through the MCP servers so they can be audited or disabled centrally.
## Supply-Chain Safeguards
- The repository includes a git `pre-commit` configuration that runs `cargo fmt`, `cargo check`, and `cargo clippy -- -D warnings` on every commit.
- Pull requests generated with the assistance of AI tooling must receive manual maintainer review before merging. Contributors are asked to declare AI involvement in their PR description so maintainers can double-check the changes.
Additional recommendations for operators (e.g., running Owlen on shared systems) are maintained in `docs/security.md` (planned) and the issue tracker.

You have access to tools for reading files, writing code, running commands, and searching the web.
## Guidelines
1. Be direct and concise in your responses
2. Use tools to gather information before making changes
3. Explain your reasoning when making decisions
4. Ask for clarification when requirements are unclear
5. Prefer editing existing files over creating new ones
## Tool Usage
- Use `read` to examine file contents before editing
- Use `glob` and `grep` to find relevant files
- Use `edit` for precise changes, `write` for new files
- Use `bash` for running tests and commands
- Use `web_search` for current information"#

# Owlen CLI
This crate is the command-line entry point for the Owlen application.
It is responsible for:
- Parsing command-line arguments.
- Loading the configuration.
- Initializing the providers.
- Starting the `owlen-tui` application.
There are two binaries:
- `owlen`: The main chat application.
- `owlen-code`: A specialized version for code-related tasks.
