description: Register current or specified orchestrator session UUID into agent-sessions.yaml orchestrator_uuids list to prevent sub-agent discovery capture.

# 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

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

### Options
- `--uuid <uuid>`: Explicitly register the specified orchestrator session UUID (UUID format or cline ID format).
- `--remove <uuid>`: Remove the specified UUID from the `orchestrator_uuids` list.
- `--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.

## 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`, `cline`) in the following order:

1. **CLI `argv`**:
   - `claude -r <uuid>` / `claude --session-id <uuid>`
   - `agy --conversation <uuid>`
   - `cline --id <uuid>` / `cline --session-id <uuid>`
2. **Family-Matched Environment Variables**:
   - `claude` → `CLAUDE_CODE_SESSION_ID`
   - `agy` → `ANTIGRAVITY_CONVERSATION_ID`
   - `hermes` → `HERMES_SESSION_ID`
   - `cline` → `CLINE_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.
- `3`: Detection failed — ID could not be determined.
