Zero-config P2P messaging between ggcode instances on your LAN
Every ggcode instance automatically discovers other instances on the same local network via mDNS — no relay server, no accounts, no configuration. | Feature | Description | |---------|-------------| | **Auto-discovery** | mDNS finds peers automatically — zero config | | **DM & broadcast** | Message individuals, teams, or everyone on the LAN | | **Agent-to-agent** | Route messages to `@agent` for cross-instance delegation | | **Presence** | See who's online, their project, role, team, and languages | | **File sharing** | Drag-and-drop attachments up to 10 MB | | **Read receipts** | Track message delivery and read status | | **Cross-platform** | Works in TUI, Desktop GUI, and daemon mode | | **Privacy** | Messages stay on your LAN — nothing goes through external servers | Quick example — your agent can collaborate with peers: ``` You: "ask the platform team to review my PR" Agent: lanchat(action='send_team', team='platform', message='Can you review PR #123?') ``` The built-in community key ensures interoperability regardless of individual A2A auth configuration. 📖 **[Full LAN Chat Guide →](docs/guide/lan-chat.md)** --- ## Features - **Codebase-aware** — reads, understands, and edits your entire project - **Full dev toolkit** — file edits, shell commands, Git, LSP, search, batch operations - **Semantic code search** — BM25-based `code_search` finds conceptually related code, not just keyword matches - **Code health analysis** — cyclomatic complexity, function length, nesting depth metrics via `code_health` - **Tech-debt scanner** — `scan_todos` surfaces TODO/FIXME/HACK markers with severity ranking and git-blame staleness - **Browser automation** — Go-native CDP for SPA/JS testing without Node.js or Playwright - **Screenshot capture** — full screen, window, or region screenshots for visual debugging - **Clipboard integration** — read from and write to the system clipboard - **Editor launcher** — `open_editor` opens files in the user's IDE (VS Code, Cursor, JetBrains, Vim, etc.) at a specific line/column, auto-detected from env vars - **Agent-accessible undo** — `undo_edit` lets the LLM revert its own file edits via checkpoints, avoiding error-prone fix-forward when a previous change was wrong - **Batch file operations** — `file_ops` (delete, move/rename, mkdir with sandbox enforcement and file-tracker integration) and `batch_replace` (regex/literal find-and-replace across many files in one call) replace unsafe `run_command("rm/mv")` with first-class protected tools - **Schema-constrained tool validation** — pre-execution pipeline that validates enum values, numeric bounds (min/max), string length constraints, and strips hallucinated parameters — saving wasted iterations on weak models - **Adaptive tool timeout** — per-tool category-based timeout that adapts to observed latency, replacing a flat 5-minute default with sensible bounds (30–180s per category) so hung tools fail fast instead of wasting minutes - **Exit code intelligence** — when commands fail with signals (137=OOM, 139=segfault, 134=abort, 130=SIGINT, 143=SIGTERM), the agent receives an actionable diagnostic hint instead of a bare exit code, enabling immediate root-cause diagnosis - **PTC (Programmatic Tool Calling)** — the agent writes JavaScript in a sandboxed VM to batch-call read-only tools (read_file, grep, git_log, web_search, etc.) in a single round-trip, dramatically reducing context window consumption for multi-step analysis - **MCP integration** — connect external tools and data sources, with dynamic tool refresh, server logging, full capability detection, and MCP sampling (servers can request LLM completions) - **gRPC plugins** — extend ggcode with custom tools in Go, Python, Node.js, or any language - **Multi-agent** — spawn parallel workers, delegate to teammates, A2A protocol - **Multi-provider** — OpenAI, Anthropic, Gemini, DeepSeek, Kimi, Copilot, and more; configurable reasoning effort and tool choice across all protocols - **Adaptive sampling** — per-turn temperature adjustment based on task phase: low temperature for precise code edits and error recovery, higher for exploration and creative writing - **[LAN Chat](docs/guide/lan-chat.md)** — zero-config P2P real-time messaging between instances on your LAN - **Editor integration** — JetBrains, Zed, and ACP-compatible editors via ACP - **WebUI** — built-in web interface accessible from any browser - **IM integration** — control from QQ, Telegram, Discord, Slack, Feishu, DingTalk - **Scheduled tasks** — cron jobs, reminders, and background automation - **Resumable sessions** — pause and resume any conversation - **Cross-session search** — `/search
