Comprehensive plan for adding codey-server, a WebSocket server that exposes the full agent interaction for automation and external client integration. Key design decisions: - Workspace restructure: codey (core), codey-tools, codey-cli, codey-server - Server-side tool execution with approval promotion over WebSocket - Reuse existing types with Serialize derives where possible - ToolEventMessage as serializable mirror of ToolEvent (channels can't serialize) - Session event loop mirrors app.rs structure
Adds Serialize/Deserialize derives to core types to enable WebSocket and other wire protocol integrations: - AgentStep, Usage, RequestMode in agent.rs - ToolCall, ToolDecision in exec.rs - Effect in pipeline.rs - Edit, ToolPreview in ide/mod.rs Adds ToolEventMessage enum as a serializable version of ToolEvent. The internal ToolEvent contains oneshot::Sender channels for the approval flow which cannot be serialized. ToolEventMessage mirrors the structure but omits these channels, with a to_message() conversion. Exports new types from lib.rs public API: - ToolEventMessage, ToolDecision, Effect
Major refactor to support WebSocket server as a separate binary: Workspace structure: - crates/codey: Core library + CLI binary (with cli feature) - crates/codey-server: WebSocket server binary Changes: - Move src/ to crates/codey/src/ - Create workspace Cargo.toml with shared dependencies - Add codey crate with cli feature for optional TUI/tool deps - Add codey-server crate with WebSocket protocol and session management codey-server implements: - protocol.rs: ClientMessage/ServerMessage JSON protocol - session.rs: Per-connection agent session with event loop - server.rs: WebSocket listener and connection handling - main.rs: CLI entry point with configuration The server currently streams AgentStep events over WebSocket and promotes tool approvals to the client. Full ToolExecutor integration is planned for follow-up. Makefile updated with workspace-aware targets: - make build: Build all workspace members - make build-cli: Build just the CLI - make build-server: Build just the server - make run / make run-server: Run respective binaries
- Export CLI-gated types (Config, ToolFilters, ToolEvent, ToolExecutor) from lib.rs - Load config from ~/.config/codey/config.toml in server main.rs - Compile ToolFilters from config for auto-approve/deny behavior - Session uses Arc<ToolFilters> shared across connections - ToolExecutor handles server-side tool execution - Tools matching filters auto-approved/denied, others bubble to WebSocket - Add toml dependency to codey-server for config parsing
- clients/python/codey_client/schemas.py: Pydantic models for all protocol types - clients/python/codey_client/client.py: Async WebSocket client with high-level API - clients/python/examples/basic_chat.py: Interactive chat example - clients/INTEGRATION.md: Protocol documentation for implementing clients The Python client provides: - Full type safety with Pydantic models matching Rust protocol types - Async context manager for easy connection lifecycle - High-level chat() and stream_text() methods - Configurable tool approval (auto-approve, callback, or default deny)
