+# 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).
+
+## [1.1.0] - 2026-01-25
+
+### Added
+
+- **Dynamic MCP Server**: Implemented a full Model Context Protocol server in `src/main.rs`.
+  - Automatically scans `skills/*/SKILL.md` to register tools.
+  - Handles JSON-RPC handshake (`initialize`, `notifications/initialized`).
+  - Implemented `tools/list` and `tools/call` parsing.
+- **Skill Loader**: New module `src/skills.rs` to deserialize skill metadata and map them to executable scripts.
+- **Pollution Protection**: Enforced `Stdio::piped()` for all child process executions to prevent tool output from corrupting the JSON-RPC stream.
+
+### Fixed
+
+- **Gemini Connection Crash**: Resolved `MCP error -32000: Connection closed` by providing a valid server implementation that holds the connection open (Fixes Issue #3).
+- **Ambiguous Execution**: Updated `gemini-extension.json` to explicitly use `--bin rust-agentic-skills`, preventing `cargo run` from executing test binaries or scripts accidentally.
+- **Dependency Hygiene**: Synced dependencies with upstream requirements (`tokio` full features, `anyhow`) while adding `serde_yaml` for metadata parsing.
+
+### Changed
+
+- Refactored `src/main.rs` from a static placeholder to a dynamic host.
+- Updated project architecture to treat the file system (`skills/`) as the source of truth for agent capabilities.

 ### 2. Gemini CLI (Extension)
 
-Compatible with the Gemini CLI tool integration.
+Compatible with the Gemini CLI tool via the **Model Context Protocol (MCP)**. This repo provides a dynamic server that auto-discovers skills.
 
-1.  Register the extension using `.Gemini-extension.json`.
-2.  **Result**: The router skill becomes the entry point for "Rust Guild" commands.
+1.  **Link Extension**:
+    ```bash
+    gemini extensions link .
+    ```
+2.  **Activate**:
+    ```bash
+    gemini context set rust-agentic-skills
+    ```
+3.  **Result**: The `rust-agentic-skills` server starts up, reads your `skills/` directory, and dynamically routes your requests to the appropriate skill (e.g., "Lint Hunter").
 
 ### 3. Manual / Custom Agents
 
+**Running the MCP Server Manually:**
+You can run the server directly to verify standard JSON-RPC communication:
+
+```bash
+cargo run --release --bin rust-agentic-skills
+```
+
+_(Expects JSON-RPC messages on stdin)_
+
 For generic agents (ChatGPT, heavily customized setups):
 
 1.  **System Prompt**: Load [AGENTS.md](AGENTS.md) as your system instruction. It defines the **RPI (Research → Plan → Implement)** loop.
 2.  **Context Loading**: When the agent enters a specific phase (e.g., "Verification"), manually load the relevant `SKILL.md` (e.g., `skills/lint-hunter/SKILL.md`).
