agmsg

name agmsg description Cross-agent messaging via SQLite. Send messages between Claude Code, Codex, Gemini CLI, GitHub Copilot CLI, and other agents. No daemon, no network, no dependencies beyond bash and sqlite3. Agent Messaging IMPORTANT: Always use the provided scripts. NEVER directly read or edit config files, DB, or team data. There is NO register.sh — use join.sh to join a team. Shell requirement: All agmsg scripts are Bash scripts. Always execute them via bash , never via PowerShell or cmd directly. If your default shell is not Bash (e.g. PowerShell on Windows), wrap every command with bash -lc '...' . Example: bash -lc '~/.agents/skills/agmsg/scripts/send.sh myteam alice bob "hello"' . Do NOT construct DB paths manually — the scripts handle path resolution internally. If you need to redirect storage, use AGMSG_STORAGE_PATH (the supported override). How to use Step 0: First-run bootstrap agmsg keeps its SQLite database, team registry, and runtime state under ~/.agents/skills/agmsg/ . The ./install.sh install path creates that tree; the Claude Code plugin install path does not (the plugin marketplace flow only drops the skill content into ~/.claude/plugins/cache/ ). Before any other command, bootstrap if needed: if [ ! -d ~/.agents/skills/agmsg ]; then # Locate the plugin install script (any version), run it once. installer=$( ls ~/.claude/plugins/cache/fujibee-agmsg/agmsg/*/install.sh 2>/dev/null | head -1) if [ -n " $installer " ]; then bash " $installer " --cmd agmsg else echo "agmsg not installed. Either:" >&2 echo " - run ./install.sh in the agmsg repo, or" >&2 echo " - install via /plugin marketplace add fujibee/agmsg && /plugin install agmsg@fujibee-agmsg" >&2 exit 1 fi fi After this runs once, ~/.agents/skills/agmsg/ is populated and you can skip Step 0 on future invocations. Step 1: Check identity ~/.agents/skills/agmsg/scripts/whoami.sh " $(pwd) " < type > # type: claude-code, codex, gemini, antigravity, copilot # Returns: agent=... / multiple=true ... / suggest=true ... / not_joined=true ... Step 2a: If not in a team — join one Before first-time setup, inspect the user's request. If they ask to join, import, or bring in a team that already exists on a server, do not run join.sh . Go directly to the remote pull command under Step 2b. Before pulling, run team-list.sh --json --scope all ; if a same-named local team has binding_state none or disconnected , stop and ask the user how to proceed. After pull succeeds, return here so the user can register a new local agent in the team that pull just created. Ask the user for a team name. If it's an existing team, run team.sh <team> first to see the current roster and note the names already in use. Look for a naming convention already in play (e.g. a shared base name with role and number suffixes ( <base>-<role><n> ), or names derived from the team name) and, when one exists, propose 2-3 unused names that extend it; otherwise propose 2-3 short, distinctive identity names (not a bare tool-type label like codex / cc ). Either way, names must not collide with the roster. For a brand-new team, skip the roster check and just ask. Then run: ~/.agents/skills/agmsg/scripts/join.sh <team> <agent_name> < type > " $(pwd) " [--force] Do NOT manually edit config files. Always use join.sh. If the name was recently renamed away with rename.sh , join.sh refuses to revive it (printing the new name it maps to) instead of silently re-registering it — this guards against a CLI slash-command history resubmitting actas <old_name> after a rename. Pass --force only for a deliberate, unrelated reuse of that exact name. Step 2b: If already in a team — execute command Default (no arguments): IMMEDIATELY check inbox. Do NOT ask what to do. # Check inbox (marks messages as read) — DEFAULT action ~/.agents/skills/agmsg/scripts/inbox.sh <team> <agent_id> # Send a message (from/to must already be registered in <team>; add --force to bypass) ~/.agents/skills/agmsg/scripts/send.sh <team> <from_agent> <to_agent> "<message>" [--force] # Message history ~/.agents/skills/agmsg/scripts/history.sh <team> [agent_id] [ limit ] # Export a team's message history as JSONL — one message_sent record per line, # chronological. Default to stdout (pipeable); --out <file> writes a file. # --agent limits to one agent; --limit keeps the most recent N (omit = all # currently retained). Output is plaintext (the local store is plaintext). ~/.agents/skills/agmsg/scripts/export.sh --team <team> [--agent <agent>] [-- limit N] [--out <file>] # List team members ~/.agents/skills/agmsg/scripts/team.sh <team> # List every locally known team (read-only, secret-free — "agmsg team list"). # Distinct from `team.sh <team>` above: check for "team list" FIRST so # "list" is never mistaken for a team name. --json emits a strict, # versioned object ({schema_version, teams: [{name, remote_team_id, scope, # binding_state}]}) and exits non-zero with NO payload if any team was # unreadable or the count was truncated — never a partial list dressed up # as complete.

Parse either <team> <old_name> <new_name> , or <old_name> <new_name> only when this agent belongs to exactly one team. Never invent either name. Before execution, repeat the resolved team, old name, and new name and ask the user to confirm. Wait for confirmation. Run: bash ~/.agents/skills/agmsg/scripts/rename.sh <team> <old_name> <new_name> Show the result. For a connected team, the member_renamed journal event propagates the rename to other machines. If argument starts with "rename-team": Accept only an explicit user request. Parse <old_team> <new_team> . Never invent either team name. Before execution, repeat the old and new team names and ask the user to confirm. Wait for confirmation. Run: bash ~/.agents/skills/agmsg/scripts/rename-team.sh <old_team> <new_team> Show the result. Remote sync Remote setup is no-auth. Do not ask for a token or create one. If argument starts with "remote connect": Parse the required --endpoint <url> and <team> , plus optional --e2ee . Run: bash ~/.agents/skills/agmsg/scripts/remote.sh connect --endpoint <url> [--e2ee] <team> Show the output to the user. Plain sync is the default; pass --e2ee only when the user explicitly requests end-to-end encryption. The choice is fixed by the first connect. End by showing this copy-paste command for the other machine, with the actual endpoint and team substituted: bash ~/.agents/skills/agmsg/scripts/remote.sh pull --endpoint <actual-url> <actual-team> If argument starts with "remote pull": When the user asks to join or bring in a team that already exists on a server, NEVER use join.sh , create a team, or create a same-named local team. Always use remote pull. Before pulling, check for a same-named local team. If one already exists without an active remote connection, stop and ask the user how to proceed; do not overwrite, merge, connect, or rename it on your own. Parse the required --endpoint <url> and <team> , plus optional --team-id <uuid> . Run: bash ~/.agents/skills/agmsg/scripts/remote.sh pull --endpoint <url> [--team-id <uuid>] <team> Show the output to the user. Machine B needs its own install, not just its own environment variables. Only remote.sh , remote-sync.sh , key.sh and the two internal helpers read AGMSG_SYNC_CONNECTION_DIR ; send.sh , history.sh , team.sh and inbox.sh resolve the team config from the install directory. So a pull driven by environment variables alone succeeds, and the send that is supposed to confirm it then reports the team as missing — the failure lands one step after the cause. See "Use a separate install for testing" in docs/remote-setup.md . If argument starts with "remote unlock": Parse <team> , --bundle <file> , and --confirm-digest <sha256> . Run: bash ~/.agents/skills/agmsg/scripts/remote.sh unlock <team> --bundle <file> --confirm-digest <sha256> The snapshot digest must be compared over a separate live channel. Never infer or auto-confirm it. The bundle is permanent secret key material; tell the user to transfer and handle it only through their own trusted channel, never by pasting it into agent chat. Show the complete result, including the imported-envelope count and engine PID. The advanced form with repeatable --snapshot plus --identity or --identity-stdin remains available when explicitly requested. If argument starts with "remote status": Parse an optional <team> and --json . Run: bash ~/.agents/skills/agmsg/scripts/remote.sh status [<team>] [--json] Show the output to the user. If argument starts with "remote sync start": Parse the required <team> . Run: bash ~/.agents/skills/agmsg/scripts/remote.sh sync start <team> Show the output to the user. If argument starts with "remote disconnect": Parse the required <team> . Run: bash ~/.agents/skills/agmsg/scripts/remote.sh disconnect <team> Show the output to the user. If argument starts with "remote forget": Parse the required <team> . This permanently deletes that team's local roster, history, keys, trust, and sync state, but never changes the server. Do not add --yes yourself. Run: bash ~/.agents/skills/agmsg/scripts/remote.sh forget <team> The command requires the user to confirm in their terminal. If this agent has no interactive terminal, show the deletion summary and tell the user to rerun the displayed command directly; never bypass confirmation for them. End-to-end encryption If argument starts with "key generate" followed by an optional team name: Run: bash ~/.agents/skills/agmsg/scripts/key.sh generate [<team>] Show the full output to the user, including the mandatory key-backup notice. If argument starts with "key show": Parse an optional team name and --reveal-secret . Run: bash ~/.agents/skills/agmsg/scripts/key.sh show [<team>] [--reveal-secret]
