- Introduce reference MCP presets with installation/audit helpers and remove legacy connector lists.
- Add CLI `owlen tools` commands to install presets or audit configuration, with optional pruning.
- Extend the TUI :tools command to support listing presets, installing them, and auditing current configuration.
- Document the preset workflow and provide regression tests for preset application.
- Reject dotted tool identifiers during registration and remove alias-backed lookups.
- Drop web.search compatibility, normalize all code/tests around the canonical web_search name, and update consent/session logic.
- Harden CLI toggles to manage the spec-compliant identifier and ensure MCP configs shed non-compliant entries automatically.
Acceptance Criteria:
- Tool registry denies invalid identifiers by default and no alias codepaths remain.
Test Notes:
- cargo check -p owlen-core (tests unavailable in sandbox).
AC:
- :web on/off updates tool exposure immediately and persists the toggle.
- owlen providers web --enable/--disable reflects the same setting and reports current status.
- Help/docs cover the new toggle paths and troubleshooting guidance.
Tests:
- cargo test -p owlen-cli
- cargo test -p owlen-core toggling_web_search_updates_config_and_registry
- Introduce new `owlen-markdown` crate that converts Markdown strings to `ratatui::Text` with headings, lists, bold/italic, and inline code.
- Add `render_markdown` config option (default true) and expose it via `app.render_markdown_enabled()`.
- Implement `:markdown [on|off]` command to toggle markdown rendering.
- Update help overlay to document the new markdown toggle.
- Adjust UI rendering to conditionally apply markdown styling based on the markdown flag and code mode.
- Wire the new crate into `owlen-tui` Cargo.toml.
Introduce `McpCommand` enum and handlers in `owlen-cli` to manage MCP server registrations, including adding, listing, and removing servers across configuration scopes. Add scoped configuration support (`ScopedMcpServer`, `McpConfigScope`) and OAuth token handling in core config, alongside runtime refresh of MCP servers. Implement toast notifications in the TUI (`render_toasts`, `Toast`, `ToastLevel`) and integrate async handling for session events. Update config loading, validation, and schema versioning to accommodate new MCP scopes and resources. Add `httpmock` as a dev dependency for testing.
- Introduce `MessageRenderContext` and `MessageCacheEntry` for caching wrapped lines per message.
- Implement `render_message_lines_cached` using cache, invalidating on updates.
- Add role/style helpers and content hashing for cache validation.
- Throttle UI redraws in the main loop during active streaming (50 ms interval) and adjust idle tick timing.
- Update drawing logic to use cached rendering and manage draw intervals.
- Remove unused `role_color` function and adjust imports accordingly.
Introduce `DetailedModelInfo` and `ModelInfoRetrievalError` structs for richer model data.
Add `ModelDetailsCache` with TTL‑based storage and async API for get/insert/invalidate.
Extend `OllamaProvider` to fetch, cache, refresh, and list detailed model info.
Expose model‑detail methods in `Session` for on‑demand and bulk retrieval.
Add `ModelInfoPanel` widget to display detailed info with scrolling support.
Update TUI rendering to show the panel, compute viewport height, and render model selector labels with parameters, size, and context length.
Adjust imports and module re‑exports accordingly.
Deletes the `owlen-ollama` Cargo.toml and source files, fully removing the Ollama provider from the workspace. This aligns the project with the MCP‑only architecture and eliminates direct provider dependencies.
- Detect terminal color support and automatically switch to the new `ansi_basic` theme when only 16‑color support is available.
- Introduce `OfflineProvider` that supplies a placeholder model and friendly messages when no providers are reachable, keeping the TUI usable.
- Add `CONFIG_SCHEMA_VERSION` (`1.1.0`) with schema migration logic and default handling in `Config`.
- Update configuration saving to persist the schema version and ensure defaults.
- Register the `ansi_basic` theme in `theme.rs`.
- Extend `ChatApp` with `set_status_message` to display custom status lines.
- Update documentation (architecture, Vim mode state machine) to reflect new behavior.
- Add async‑trait and futures dependencies required for the offline provider implementation.
- Export `LLMProvider` from `owlen-core` and replace public `Provider` re-exports.
- Convert `OllamaProvider` to implement the new `LLMProvider` trait with associated future types.
- Adjust imports and trait bounds in `remote_client.rs` to use the updated types.
- Add comprehensive provider interface tests (`provider_interface.rs`) verifying router routing and provider registry model listing with `MockProvider`.
- Align dependency versions across workspace crates by switching to workspace-managed versions.
- Extend CI (`.woodpecker.yml`) with a dedicated test step and generate coverage reports.
- Update architecture documentation to reflect the new provider abstraction.
This commit fixes 12 categories of errors across the codebase:
- Fix owlen-mcp-llm-server build target conflict by renaming lib.rs to main.rs
- Resolve ambiguous glob re-exports in owlen-core by using explicit exports
- Add Default derive to MockMcpClient and MockProvider test utilities
- Remove unused imports from owlen-core test files
- Fix needless borrows in test file arguments
- Improve Config initialization style in mode_tool_filter tests
- Make AgentExecutor::parse_response public for testing
- Remove non-existent max_tool_calls field from AgentConfig usage
- Fix AgentExecutor::new calls to use correct 3-argument signature
- Fix AgentResult field access in agent tests
- Use Debug formatting instead of Display for AgentResult
- Remove unnecessary default() calls on unit structs
All changes ensure the project compiles cleanly with:
- cargo check --all-targets ✓

This commit completes Phase 10 of the MCP migration by removing all
direct provider usage from CLI/TUI and enforcing MCP-first architecture.
## Changes
### Core Architecture
- **main.rs**: Replaced OllamaProvider with RemoteMcpClient
- Uses MCP server configuration from config.toml if available
- Falls back to auto-discovery of MCP LLM server binary
- **agent_main.rs**: Unified provider and MCP client to single RemoteMcpClient
- Simplifies initialization with Arc::clone pattern
- All LLM communication now goes through MCP protocol
### Dependencies
- **Cargo.toml**: Removed owlen-ollama dependency from owlen-cli
- CLI no longer knows about Ollama implementation details
- Clean separation: only MCP servers use provider crates internally
### Tests
- **agent_tests.rs**: Updated all tests to use RemoteMcpClient
- Replaced OllamaProvider::new() with RemoteMcpClient::new()
- Updated test documentation to reflect MCP requirements
- All tests compile and run successfully
### Examples
- **Removed**: custom_provider.rs, basic_chat.rs (deprecated)
- **Added**: mcp_chat.rs - demonstrates recommended MCP-based usage
- Shows how to use RemoteMcpClient for LLM interactions
- Includes model listing and chat request examples
### Cleanup
- Removed outdated TODO about MCP integration (now complete)
- Updated comments to reflect current MCP architecture
## Architecture
```
CLI/TUI → RemoteMcpClient (impl Provider)
↓ MCP Protocol (STDIO/HTTP/WS)
MCP LLM Server → OllamaProvider → Ollama
```
## Benefits
- ✅ Clean separation of concerns
- ✅ CLI is protocol-agnostic (only knows MCP)
- ✅ Easier to add new LLM backends (just implement MCP server)
- ✅ All tests passing
- ✅ Full workspace builds successfully

- Fix ACTION_INPUT regex to properly capture multiline JSON responses
- Changed from stopping at first newline to capturing all remaining text
- Resolves parsing errors when LLM generates formatted JSON with line breaks
- Enhance tool schemas with detailed descriptions and parameter specifications
- Add comprehensive Message schema for generate_text tool
- Clarify distinction between resources/get (file read) and resources/list (directory listing)
- Include clear usage guidance in tool descriptions
- Set default model to llama3.2:latest instead of invalid "ollama"
- Add parse error debugging to help troubleshoot LLM response issues
The agent infrastructure now correctly handles multiline tool arguments and
provides better guidance to LLMs through improved tool schemas. Remaining
errors are due to LLM quality (model making poor tool choices or generating
malformed responses), not infrastructure bugs.
