multi-agent-mux-orc-onboard

Registers an orchestrator session UUID into the orchestrator_uuids list of .mam/agent-sessions.yaml (and underlying state DB). This ensures that find_workspace_uuid and verify_session_uuid in lib.sh exclude orchestrator conversations when discovering unassigned sub-agent session UUIDs.

Usage

.agents/skills/multi-agent-mux-orc-onboard/scripts/orc_onboard.sh [OPTIONS]

Options

• --uuid <uuid>: Explicitly register the specified orchestrator session UUID.
• --remove <uuid>: Remove the specified UUID from the orchestrator_uuids list.
• --purge-conversation: With --remove, also delete the conversation's on-disk artifacts through its agent adapter (Issue #13). Irreversible — requires --yes; refused (exit 5, registration untouched) while a live process still references the conversation — including the session the command itself runs in: its session-id variable (CLAUDE_CODE_SESSION_ID, ANTIGRAVITY_CONVERSATION_ID, HERMES_SESSION_ID, GROK_SESSION_ID, OPENCODE_SESSION_ID) equals the UUID, or the nearest agent CLI ancestor names it on its command line. An orchestrator therefore cannot purge its own conversation from inside that very session. Any live process whose command line contains the UUID counts, not only a resumed session — an editor, a grep or a delegation wrapper whose prompt merely mentions it blocks the purge too; if it is refused, find the process with ps -axww | grep <uuid>.
• --yes: Skip the --purge-conversation confirmation (without it the script prints the danger notice and exits 4).
• --agent <name>: Adapter to purge with (claude|agy|hermes|grok|opencode|codex). Default auto: each adapter is asked whether it owns an artifact for the UUID (agy → ~/.gemini/antigravity-cli/conversations/<uuid>.db etc.). Needed because orchestrator_uuids stores bare UUIDs, not the agent kind.
• --list: Display all currently registered orchestrator UUIDs.
• --no-autodetect: Disable process ancestry auto-detection when --uuid is not provided.
• --dry-run: Output proposed changes without mutating the state registry.

Purging the orchestrator conversation

multi-agent-mux-stop --purge-conversation only reaches sessions that have a herdr_sessions row; the orchestrator never has one. To wipe an orchestrator conversation for good:

.agents/skills/multi-agent-mux-orc-onboard/scripts/orc_onboard.sh --remove <uuid> --purge-conversation --yes
# purged: ~/.gemini/antigravity-cli/conversations/<uuid>.db
# purged: ~/.gemini/antigravity-cli/brain/<uuid>
# ...
# residual: none (agent: agy)

The purge runs before the registry update, so a refused purge (conversation in use, exit 5) changes nothing. If no adapter finds an artifact for the UUID the registration is still removed with a warning. For agy the adapter also removes the SQLite sidecars (-wal/-shm/-journal), the title annotation and the presence lock (Issue #10) and reports anything under ~/.gemini/antigravity-cli that still carries the UUID as WARN residual:. Orphaned leftovers — a WAL, annotation or lock whose DB is already gone — still resolve to agy and are purged, and the in-use check asks lsof about every one of those paths, so a holder that keeps only the presence lock open (naming the UUID nowhere) is refused too.

Auto-Detection Hierarchy (Rev.2)

When --uuid is omitted, orc_onboard.sh inspects the process ancestry tree of the nearest agent ancestor (claude, agy, hermes, grok, opencode, codex) in the following order:

1. CLI argv:
   • claude -r <uuid> / claude --session-id <uuid>
   • agy --conversation <uuid>
   • grok --session-id <uuid> / grok --resume <uuid>
   • opencode --session <uuid>
   • codex resume <uuid>
2. Family-Matched Environment Variables:
   • claude → CLAUDE_CODE_SESSION_ID
   • agy → ANTIGRAVITY_CONVERSATION_ID
   • hermes → HERMES_SESSION_ID
   • grok → GROK_SESSION_ID
3. Fallback:
   • If no valid ID matching the nearest agent family is found, exits with status 3 (Could not detect orchestrator ID).

Exit Statuses

• 0: Success (registered, removed, listed, or already present).
• 1: Conflict — the ID is currently owned by a running sub-agent session row.
• 2: Invalid arguments or malformed ID format (including --purge-conversation without --remove).
• 3: Detection failed — ID could not be determined.
• 4: --purge-conversation needs --yes — nothing changed.
• 5: Purge refused — the conversation is still in use by a live process; nothing changed.
