multi-agent-mux-status	Read-only instant snapshot of all agent tmux sessions — name, YAML status, tmux alive, pane cmd/cwd, resume UUID on disk, and any drift. No Kanban, no mutation. Reuses reconcile.sh --dry-run for the diff logic. Use when you want to know 'what's running RIGHT NOW' without spinning up a Kanban monitor worker.	1.0.0	godopu	MIT	linux macos	terminal tmux	hermes tags related_skills prereq_skills agent tmux claude antigravity agy status read-only snapshot multi-agent-mux-create multi-agent-mux-resume multi-agent-mux-stop multi-agent-mux-monitor multi-agent-mux-create multi-agent-mux-monitor

Multi-Agent Status — Read-Only Instant Snapshot

Companion skills: multi-agent-mux-create (start), multi-agent-mux-resume (re-attach), multi-agent-mux-stop (terminate), multi-agent-mux-monitor (live polling). Tmux Isolation: status 명령은 YAML에 등록된 모든 세션의 격리 서버(tmux_server 필드)를 자동으로 조회하여 상태를 확인하므로, TMUX_SERVER_NAME 환경변수를 수동으로 지정하지 않아도 모든 격리 서버의 세션 상태를 통합 조회합니다. Single source of truth: ./.mam/agent-sessions.yaml.

What this skill does

Print a single table of every agent tmux session, comparing YAML state to actual tmux state. No mutation. No Kanban. No polling loop.

This is the "what's running right now?" answer — faster than dispatching multi-agent-mux-monitor (which polls every 30s) and safer than reconcile.sh --once --emit-diff (which mutates as a side effect).

Pre-flight

command -v tmux
command -v python3
test -f .mam/agent-sessions.yaml

If agent-sessions.yaml doesn't exist or is malformed → print clear error, exit 1. Do not create it. (Use multi-agent-mux-create first.)

Workflow

bash .agents/skills/multi-agent-mux-status/scripts/status.sh [--json]

The script:

1. Calls reconcile.sh --once --emit-diff --dry-run (read-only; no YAML mutation) for the drift snapshot
2. Loads agent-sessions.yaml (read-only) to enrich the table
3. For each row in tmux_sessions[]:
   • tmux alive? (via tmux has-session -t <name>)
   • pane cmd, cwd (via tmux list-panes)
   • resume UUID on disk? (claude: $CLAUDE_PROJECT_DIR/<key>/<uuid>.jsonl with default ~/.claude/projects/; agy: $HOME_DIR/.gemini/antigravity-cli/conversations/<uuid>.db with default ~/.gemini/...)
4. For each tmux session matching *-creator-* not in YAML → flag as "unregistered"
5. Prints a table (default) or JSON (with --json)

Output format (default = aligned table)

Drift classes (read-only — never mutates)

Class	Detection	Meaning
A	YAML running, tmux dead	session died without going through multi-agent-mux-stop. Could auto-terminate but won't — that's multi-agent-mux-monitor's job.
B	tmux alive, not in YAML	ad-hoc session someone started without multi-agent-mux-create. Suggest: "use multi-agent-mux-create to register, or tmux kill-session to clean up."
C	YAML has claude_session_id_own: null AND a new *.jsonl exists	new session id materialized; suggest: "run multi-agent-mux-resume or reconcile to register it."
D	YAML has UUID in agent_identities, but the on-disk artifact is gone	stale UUID; user should multi-agent-mux-stop --purge-conversation to clean up.

Pitfalls

• Do NOT use this skill to drive mutations — the output is a snapshot, not a call to action. If you need to fix drifts, dispatch multi-agent-mux-monitor (Kanban worker) or run multi-agent-mux-resume / multi-agent-mux-stop manually.
• Read-only is enforced by script — status.sh opens the YAML with open(path) (no 'w'), never calls tmux kill-session, never writes anywhere. The reconcile.sh --dry-run mode is the same path.
• If agent-sessions.yaml is malformed — print the YAML error verbatim and exit 1. Do NOT attempt recovery (that's multi-agent-mux-stop --purge-conversation or manual edit's job).
• Sessions outside the <workspace>-creator-* naming convention are still shown but tagged ad-hoc — they didn't go through multi-agent-mux-create and aren't tracked in YAML.

When to use

• "Is the claude session still running?" → this skill, not the monitor
• "What UUID does this workspace have?" → this skill
• "Is there drift between YAML and reality?" → this skill, then dispatch monitor or fix manually
• Quick sanity check before dispatching a long Kanban task

When NOT to use

• Continuous live tracking → multi-agent-mux-monitor (Kanban worker)
• Recovering from corruption → manual edit + .bak restore
• Polling more than once a minute → multi-agent-mux-monitor (it dedupes)
