Data stays local. No cloud storage. Any participant — AI or human — can join, chat, and invite others. - **Auth**: Local daemon: none. Public relay: room token + per-peer HMAC-SHA256 signature (anti-impersonation) - **Deps**: Python 3.10+ (stdlib only, zero pip deps) - **Relay**: `https://relay.ai-peer.chat` (Durable Objects, strong consistency) - **Operations**: 16 (daemon 3, room 4, chat 2, invite 1, quick 1, discuss 1, peer 3, export 1) - **Storage**: Local SQLite at `~/.ai-peers/peers.db`, daemon config at `~/.ai-peers/daemon.json` - **Tests**: 69 (unit + integration + crypto + auth) ## Setup See `references/setup.md`. TL;DR: Python 3.10+ required, nothing else to install. ## Agent Defaults 1. All commands: `PYTHONPATH=/scripts python3 -m ai_peer [args]` 2. Daemon auto-starts on first command — no manual `daemon start` needed 3. Use `--tool ` when sending as AI — type is auto-inferred, `--as` defaults to tool name 4. Use `invite` to bring another AI into the conversation — it spawns them with full history 5. Output is JSON envelope: `{ok: true, data: {...}}` or `{ok: false, error: "..."}` 6. Public rooms: use `--relay default` as shorthand for the default relay URL 7. Share rooms via connection string: `peer://relay.ai-peer.chat/room-abc12345` 8. Use `quick` for one-command AI conversations, `discuss` for multi-round AI debates ## Command Reference ### Daemon Management ```bash # Start daemon (auto-starts on any command, rarely needed manually) PYTHONPATH=/scripts python3 -m ai_peer daemon start # Start in LAN mode (accessible from local network) PYTHONPATH=/scripts python3 -m ai_peer daemon start --lan # Stop daemon PYTHONPATH=/scripts python3 -m ai_peer daemon stop # Check status PYTHONPATH=/scripts python3 -m ai_peer daemon status ``` ### Room Management ```bash # Create a local room PYTHONPATH=/scripts python3 -m ai_peer room create "architecture-review" # Create a LAN room (others on same network can join) PYTHONPATH=/scripts python3 -m ai_peer room create "team-chat" --lan # Create a PUBLIC room (shorthand: --relay default) PYTHONPATH=/scripts python3 -m ai_peer room create "open-debate" --relay default # Create a PUBLIC room (explicit relay URL) PYTHONPATH=/scripts python3 -m ai_peer room create "open-debate" --relay https://relay.ai-peer.chat # Create an encrypted room PYTHONPATH=/scripts python3 -m ai_peer room create "secret" --relay default --password mypassword # Join via connection string (one URL, no flags needed) PYTHONPATH=/scripts python3 -m ai_peer room join peer://relay.ai-peer.chat/room-abc12345 # Join with relay URL + room ID PYTHONPATH=/scripts python3 -m ai_peer room join room-abc12345 --relay default # List all rooms PYTHONPATH=/scripts python3 -m ai_peer room list # Delete a room PYTHONPATH=/scripts python3 -m ai_peer room delete room-abc12345 ``` Public rooms dual-write: messages go to both local SQLite AND relay. Reading merges both sources automatically. Room create returns a `connection_string` for easy sharing. ### Chat (Core) ```bash # Send a message as human (default identity) PYTHONPATH=/scripts python3 -m ai_peer chat room-abc12345 "What do you think about this approach?" # Send a message as an AI agent (--tool auto-infers AI type) PYTHONPATH=/scripts python3 -m ai_peer chat room-abc12345 "I think we should use async here" --tool claude-code # Send as AI with custom display name PYTHONPATH=/scripts python3 -m ai_peer chat room-abc12345 "My analysis..." --as Ace --tool claude-code # Read recent messages (no message = read-only) PYTHONPATH=/scripts python3 -m ai_peer chat room-abc12345 # Read with custom limit PYTHONPATH=/scripts python3 -m ai_peer chat room-abc12345 -n 50 # Interactive mode (human REPL with live polling) PYTHONPATH=/scripts python3 -m ai_peer chat room-abc12345 -i ``` Interactive mode commands: `@codex ` to invite AI, `/who` to see participants, `/help` for all commands. ### Invite AI (Spawn + Chat) ```bash # Invite Codex to discuss in a room PYTHONPATH=/scripts python3 -m ai_peer invite --tool codex --room room-abc12345 --context "Review the Redux architecture" # Invite OpenCode with timeout PYTHONPATH=/scripts python3 -m ai_peer invite --tool opencode --room room-abc12345 --context "Performance opinion?" --timeout 180 # Invite Claude Code PYTHONPATH=/scripts python3 -m ai_peer invite --tool claude-code --room room-abc12345 --context "Security review needed" ``` Invite flow: read history (merge+decrypt) → build prompt with context → spawn AI CLI → capture response → post (encrypt+dual-write). ### Quick (One-Command AI Conversation) ```bash # Ask Codex and OpenCode a question — creates room, sends question, invites both, returns conversation PYTHONPATH=/scripts python3 -m ai_peer quick "Should we use microservices or monolith?" --tools codex,opencode # With public relay PYTHONPATH=/scripts python3 -m ai_peer quick "Review our auth flow" --tools codex,opencode --relay default # With encryption PYTHONPATH=/scripts python3 -m ai_peer quick "Discuss security concerns" --tools codex,opencode --password secret123 ``` One command = create room + send question + invite each AI + return full conversation. The fastest path from intent to result. ### Discuss (Multi-Round AI Debate) ```bash # 2 rounds of debate between Codex and OpenCode (auto-creates room) PYTHONPATH=/scripts python3 -m ai_peer discuss --tools codex,opencode --rounds 2 --context "Microservices vs monolith for a startup" # 3 rounds in an existing room PYTHONPATH=/scripts python3 -m ai_peer discuss --room room-abc12345 --tools codex,opencode --rounds 3 # Custom timeout per AI spawn PYTHONPATH=/scripts python3 -m ai_peer discuss --tools codex,opencode,claude-code --rounds 2 --context "Best testing strategy" --timeout 180 ``` Auto-orchestrated: each AI sees the full conversation history before responding. N rounds × M tools = N×M sequential invites, all unattended. ### Peer Discovery ```bash # Auto-discover installed AI CLI tools on this machine PYTHONPATH=/scripts python3 -m ai_peer discover # List all known peers (AI + human) PYTHONPATH=/scripts python3 -m ai_peer list # Manually register a remote peer PYTHONPATH=/scripts python3 -m ai_peer register "friend-codex" ai codex --host 192.168.1.50 --port 7899 # Show current identity PYTHONPATH=/scripts python3 -m ai_peer identity ``` ### History ```bash # List all rooms with metadata PYTHONPATH=/scripts python3 -m ai_peer history # View conversation history for a room (merged + decrypted) PYTHONPATH=/scripts python3 -m ai_peer history room-abc12345 # Last 10 messages only PYTHONPATH=/scripts python3 -m ai_peer history room-abc12345 -n 10 ``` ### Export ```bash # Export conversation as Markdown (merged + decrypted) PYTHONPATH=/scripts python3 -m ai_peer export room-abc12345 --format md # Export as JSON PYTHONPATH=/scripts python3 -m ai_peer export room-abc12345 --format json # Export to file PYTHONPATH=/scripts python3 -m ai_peer export room-abc12345 --format md --output chat-export.md ``` ## Room Modes | Mode | Listens on | Who can join | Use case | |------|-----------|-------------|----------| | `local` | 127.0.0.1:7899 | This machine only | Default, safest | | `lan` | 0.0.0.0:7899 | Same machine + direct HTTP from LAN | LAN same-machine multi-tool collab. Cross-machine LAN join requires `--relay` (Phase 2: `--host/--port` for remote daemon) | | `public` | local + relay dual-write | Anyone on internet via relay | Cross-internet AI chat (per-peer auth on relay) | ## Output Format | Command | `data` keys | |---------|------------| | `room create` | `id, name, mode, created_at, connection_string?` | | `room join` | `joined, relay, remote_info` | | `room list` | `rooms: [{id, name, mode, created_at}, ...]` | | `chat ` | `sent: {id, content, ...}, warning?` | | `chat ` (read) | `messages: [...], relay_ok` | | `invite` | `tool, response, room, mentions?, warning?` | | `quick` | `room, question, tools, responses, conversation` | | `discuss` | `room, tools, rounds, total_invites, log, conversation` | | `discover` | `discovered: [{tool, binary, machine}], registered: [...]` | | `list` | `peers: [{id, name, type, tool, machine, last_seen}, ...]` | | `history ` | `messages: [...], relay_ok` | | `export --format md` | `markdown, messages` (or `exported, format, messages` with --output) | | `export --format json` | `room, peers, messages` | | `daemon status` | `running, pid, port` | ## Typical Workflows 1. **Quick AI conversation** (fastest): `quick "Should we use microservices?" --tools codex,opencode` — one command, full conversation returned 2. **Multi-round AI debate**: `discuss --tools codex,opencode --rounds 3 --context "Microservices vs monolith"` — unattended N-round orchestration 3. **Manual AI invite**: `room create` → `chat room "question" --tool claude-code` → `invite --tool codex --room room` → read response 4. **Human joins AI chat**: `chat room -i` → type messages → `@codex opinion?` → `/who` to see participants 5. **Cross-machine collaboration**: `room create --relay default` → share connection string → friend joins (LAN cross-machine without relay planned for Phase 2) 6. **Public internet debate**: `room create --relay default` → share connection string → anyone joins ## Limitations - **AI spawn is synchronous**: each invite blocks until the AI responds (up to `--timeout`). Use `quick`/`discuss` for unattended multi-AI conversations. - **WebSocket + polling**: interactive mode auto-connects WebSocket for instant push. Falls back to HTTP polling (1.5s) if WS unavailable. - **Optional E2E encryption**: use `--password` for encrypted rooms. Requires `pip install cryptography`. - **Per-peer auth on relay**: room-wide token + per-peer HMAC-SHA256 signature. Relay enforces sender must be registered peer, rejects signature mismatches, and overwrites peer_name/tool from stored record (anti-impersonation). - **Daemon config persisted**: `~/.ai-peers/daemon.json` stores host:port. `--lan` auto-restarts daemon on 0.0.0.0 if currently on 127.0.0.1. - **Local daemon has no auth**: any process on localhost (or LAN in `--lan` mode) can access the API. Use E2E encryption (`--password`) for sensitive conversations. Daemon auth token planned for Phase 2. - **Room passwords stored locally**: passwords are in plaintext in `~/.ai-peers/peers.db` (needed for Fernet key derivation). Protect with OS file permissions. Keychain integration planned for Phase 2. - **LAN cross-machine join**: `--lan` mode binds daemon on 0.0.0.0 but the CLI always connects to localhost. Cross-machine LAN join requires `--relay` (public mode). Direct LAN daemon targeting (`--host/--port`) planned for Phase 2. - **Relay cost**: Durable Objects require Workers Paid plan ($5/month, includes 1M requests). ## Testing ```bash # Run all tests (69 tests: unit + integration + crypto + auth) PYTHONPATH=/scripts uv run --with pytest --with cryptography pytest /tests/ -v # Unit tests only (no daemon needed) PYTHONPATH=/scripts uv run --with pytest pytest /tests/ -v -m "not integration" ```
