+# Implementation Plan - Owlen Evolution
+
+## Phase 1: Asynchronous Foundation (The "Non-Blocking" Fix)
+- [~] Task: Create `Message` enum and Central Message Hub using `tokio::sync::mpsc`
+    - Define the `Message` enum to handle UI events, Agent responses, and System notifications.
+    - Create the channel infrastructure in `main.rs`.
+- [ ] Task: Refactor `main.rs` into UI and Engine Loops
+    - Separate the TUI rendering loop into its own async task or thread.
+    - Create the Engine loop (Tokio task) to handle `Message` processing.
+- [ ] Task: Switch LLM interaction to Streaming-only
+    - Update the LLM client to use streaming responses.
+    - Ensure the UI updates incrementally as tokens arrive.
+- [ ] Task: Introduce `Arc<Mutex<AppState>>` for shared state
+    - Create `AppState` struct to hold conversation history, current mode, etc.
+    - Share it between UI and Engine loops safely.
+- [ ] Task: Conductor - User Manual Verification 'Phase 1: Asynchronous Foundation (The "Non-Blocking" Fix)' (Protocol in workflow.md)
+
+## Phase 2: The Agentic Orchestrator (Middleware)
+- [ ] Task: Create `AgentManager` struct
+    - Implement the struct to manage the agent's lifecycle and state.
+- [ ] Task: Implement the "Reasoning Loop" (Thought -> Action -> Observation)
+    - Build the loop logic to process user input, generate thoughts/actions, and handle results.
+    - Implement Sliding Window context management.
+    - Implement Context Summarization logic.
+- [ ] Task: Develop Tool Registry System
+    - Define the `Tool` trait.
+    - Implement a registry to store and retrieve available tools.
+    - Implement logic to inject tool JSON schemas into the System Prompt.
+- [ ] Task: Add Sub-Agent Support
+    - Allow the Orchestrator to spawn sub-tasks if needed (basic implementation).
+- [ ] Task: Conductor - User Manual Verification 'Phase 2: The Agentic Orchestrator (Middleware)' (Protocol in workflow.md)
+
+## Phase 3: Permission & Mode Engine
+- [ ] Task: Define `AppMode` enum
+    - Add `Normal`, `Plan`, `AcceptAll` variants.
+    - Integrate `AppMode` into `AppState`.
+- [ ] Task: Implement Permission Interceptor
+    - Create logic to intercept tool calls based on `AppMode`.
+    - Implement the pause/resume mechanism for the Agent Loop.
+- [ ] Task: Implement UI for Permission Requests
+    - Add a "Status Bar Prompt" component to the TUI.
+    - Connect the prompt to the Permission Interceptor via the Message Hub.
+- [ ] Task: Build "Plan Mode" logic
+    - Implement the specific logic for batching actions in Plan Mode.
+- [ ] Task: Conductor - User Manual Verification 'Phase 3: Permission & Mode Engine' (Protocol in workflow.md)
+
+## Phase 4: Extension & Integration (The "Gemini-CLI" Layer)
+- [ ] Task: Create Dynamic Extension Loader
+    - Implement scanning of `~/.config/owlen/plugins/`.
+    - Implement reading of `config.yaml` for tool configuration.
+- [ ] Task: Implement JSON-RPC Interface
+    - Create a standard interface for communicating with external tool binaries/scripts.
+- [ ] Task: Integrate External Tools into Registry
+    - Map external tools to the `Tool` trait using the JSON-RPC bridge.
+- [ ] Task: Conductor - User Manual Verification 'Phase 4: Extension & Integration (The "Gemini-CLI" Layer)' (Protocol in workflow.md)

+# Specification: Owlen Evolution – From TUI to Agentic Workstation
+
+## Overview
+Transform Owlen from a blocking TUI into a non-blocking, agentic workstation. This involves decoupling the UI from the LLM logic, implementing a reasoning loop (Thought-Action-Observation), a robust permission system, and an extensible plugin architecture.
+
+## Functional Requirements
+
+### 1. Asynchronous Foundation
+- **Non-blocking UI:** Separate the Ratatui UI rendering loop from the LLM/Engine logic using `tokio::sync::mpsc`.
+- **Streaming Response:** LLM interactions must be streaming-only to prevent UI freezes during long generations.
+- **Central Message Hub:** Use a many-to-one or many-to-many communication pattern (via `mpsc`) to synchronize state between the background engine and the UI.
+
+### 2. Agentic Orchestrator
+- **Reasoning Loop:** Implement a core loop that follows the "Thought -> Action -> Observation" pattern.
+- **Context Management:** 
+    - **Sliding Window:** Maintain only the most recent N interactions in the immediate context.
+    - **Summarization:** Use a secondary LLM call to periodically summarize older parts of the conversation to retain long-term state without hitting token limits.
+- **Tool Registry:** Define a `Tool` trait and a system to automatically inject tool definitions (JSON Schema) into system prompts.
+
+### 3. Permission & Mode Engine
+- **Modes:** Support `Normal` (default), `Plan` (propose all actions first), and `AcceptAll` (autonomous execution).
+- **Permission Interceptor:** A mechanism to pause the agent loop when a tool requires approval.
+- **UI Integration:** Requests for permissions must be displayed in the **Status Bar** to avoid obscuring the main conversation.
+
+### 4. Extension & Integration
+- **Hybrid Extension Loader:** 
+    - Scan a default directory (e.g., `~/.config/owlen/plugins/`) for executable extensions.
+    - Allow manual configuration and overrides via `config.yaml`.
+- **JSON-RPC Interface:** Use a standardized JSON-RPC interface for communication with external extensions.
+
+## Non-Functional Requirements
+- **Performance:** UI must remain responsive (60 FPS target for rendering) even during heavy LLM tasks.
+- **Safety:** Explicit user consent required for "Write" or "Execute" operations by default.
+- **Maintainability:** Clear separation of concerns between `crates/app/ui` and `crates/core/agent`.
+
+## Acceptance Criteria
+- [ ] TUI remains responsive (can scroll/exit) while the model is "thinking" or "generating".
+- [ ] Agent can successfully call a registered tool and process its output.
+- [ ] User can approve or deny a tool execution via a status bar prompt.
+- [ ] Context window manages long conversations via summarization without crashing.
+- [ ] External scripts can be loaded as tools and invoked by the agent.
+
+## Out of Scope
+- Implementation of complex multi-agent swarms (keeping to a single orchestrator with sub-task capability).
+- Web-based UI (staying purely within TUI).
