+# Agent Guidelines for LangChain MCP
+
+## Build/Lint/Test Commands
+
+**Primary Commands:**
+
+- `mix test` - Run all tests
+- `mix test --exclude live_call` - Run only unit tests
+- `mix test test/specific_test.exs` - Run single test file
+- `mix format --check-formatted` - Check code formatting
+- `mix test --cover --exclude live_call` - check code coverage  
+- `mix quality_check` - Run all quality checks (format, credo, dialyzer, tests)
+- `mix credo --strict` - Run linting checks
+- `mix dialyzer` - Run type checking
+- `mix compile --warnings-as-errors` - Compile with strict warnings
+
+**Integration Tests:**
+
+```bash
+# Terminal 1: Start test server
+mix test_server
+
+# Terminal 2: Run integration tests
+mix test --include live_call
+```
+
+## Code Style Guidelines
+
+**Formatting:**
+
+- Line length: 100 characters (`.formatter.exs`)
+- Use `mix format` for consistent formatting
+
+**Testing:**
+
+- Unit tests use `Mimic` for mocking, tagged `:live_call` for integration tests
+- Tests in `test/` directory follow ExUnit patterns
+- Integration tests require running test server (`mix test_server`)
+
+**Architecture:**
+
+- Core modules: `LangChain.MCP.*` (Adapter, Config, SchemaConverter, ContentMapper)
+- Use proper error handling with `{:ok, _}` / `{:error, _}` tuples
+- Follow Elixir naming conventions: snake_case functions, PascalCase modules
+
+**Dependencies:**
+
+- Uses `:langchain`, `:anubis_mcp`, `:credo`, `:dialyxir`
+- Dev/test deps include mocking (`:mimic`) and docs (`:ex_doc`)

 ### Added
 
-- Initial release
+- **Status Monitor**: Lightweight solution for monitoring MCP clients in real-time with uptime percentage tracking
+- **Langchain.MCP.Client wrapper**: Decouples Anubis from application, removing dependency requirement
+- **Automated release process**: CI workflow automation for streamlined publishing
+
+### Changed
+
+- **Default test server port**: Changed from 4000 to 5000 to avoid conflicts with Phoenix applications
+- **Folder structure reorganization**: Flattened paths (`lib/langchain/mcp` → `langchain_mcp`, `test/langchain/mcp` → `test/langchain_mcp`)
+- **Markdown formatting**: Auto-formatted documentation files using CommonMark standards
+
+### Fixed
+
+- ToolExecutor issues resolved
+- Test flakiness problems fixed with centralized client management (`async: false` and proper cleanup)
+- Registry test bleed eliminated through centralized deregistration
+- Dialyzer type checking issues resolved
+- Credo linting readability/refactoring opportunities addressed

+### Quality Checks
+Before pushing, ensure code meets quality standards:
+
+```bash
+# Run all checks (same as CI)
+mix quality_check
+
+# Or run individually:
+mix format --check-formatted    # Code formatting  
+mix credo --strict              # L linting
+mix dialyzer                    # Type checking
+mix test --exclude live_call    # Unit tests only
+```
+
+The automated release workflow requires these checks to pass. Use `mix quality_check` locally before committing.
+
+### Testing
+
+- **Unit tests**: Standard ExUnit with mocking via `:mimic`
+- **Integration tests**: Tagged `:live_call`, require running test server
+
+```bash
+# Start test server (Terminal 1)
+mix test_server
+
+# Run integration tests (Terminal 2)  
+mix test --include live_call
+```
