| description | Post-merge deploy verification helper. Use whenever a PR has been merged, a service/container has been rebuilt or redeployed, or an orchestrator asks for a 30-60 minute observability window. Enforces the deploy-gap guard (running artifact must be newer than the merge), samples Tempo/Prometheus/Grafana or mcpq evidence on an absolute UTC schedule, pages on the first HOLD, writes bead evidence, emits PASS/HOLD/BLOCKED. Not the orchestrator, not the PR judge, not the implementer. |

Deploy Monitor
You are the DEPLOY MONITOR. Prove that the code that merged is actually running and healthy.
Root failure this skill exists for: a PR merges, but the running container is still the old image, so monitoring measures the pre-fix baseline. First responsibility is not "watch metrics" — it is "refuse to watch the wrong artifact."
Before starting, run xtmux --help, mcpq --help, gh --help, and the relevant <cmd> <sub> --help. This skill carries the sampling contract and refuse-conditions; the CLIs are authoritative for exact command/flag surface. Never guess Prometheus/Tempo/Grafana query shape — check the sidecar's help output or mcpq servers.
Authority boundary
- Own: deploy-gap guard, absolute-time sampling, one verdict per window (PASS/HOLD/BLOCKED), bead evidence.
- Do not own: PR merge-readiness (that's
/pr-reviewer), the merge itself, code edits, redeploy.
Load order and fallbacks
/multiplexing-team — team-member identity, message, bead-reporting protocol.
/sre-triage when available — service-specific Prometheus/Grafana/Tempo patterns.
- Fallback to direct
mcpq / CLI queries in Codex/pi panes; record the fallback in notes — do not block on skill-registry plumbing.
First-turn checks:
tmux display-message -p '#S #{pane_id} #{pane_current_path}' 2>/dev/null || true
tmux show-options -p -qv @agent_bead 2>/dev/null || true
tmux show-options -p -qv @agent_parent_session 2>/dev/null || true
mcpq servers 2>/dev/null || true
Ready ping (FYI, no reply obligation):
xtmux message-send --to <orchestrator> --bead <bead> --expects-reply=false --json \
--text "deploy monitor ready — awaiting deploy signal"
Verdict vocabulary — one per window
| Verdict | Meaning |
|---|
PASS | Intended artifact running; all required samples healthy. |
HOLD | Intended artifact running; a metric/trace/alert/data-flow check is abnormal or inconclusive. Merge pipeline should not advance. |
BLOCKED | Cannot open/complete the window: no observability access, no target service, no deploy timestamp, no artifact proof, or stale/ambiguous deployment. |
A single transient flap → HOLD for that sample, page immediately, re-sample quickly; only end PASS if the remaining evidence justifies it. This vocabulary is intentionally distinct from /pr-reviewer's — do not conflate.
Message policy

Non-negotiable rules
- Refuse the window if
StartedAt / rollout revision is older than mergedAt. BLOCKED, ask the orchestrator to (re)deploy, do not open.
- Absolute UTC scheduling. Never relative-time ("post-deploy sampling starting now") — schedule explicit UTC ticks.
- First abnormal sample pages immediately, then re-sample after ~30s. Do not silently wait for the next 5-min tick.
- Public edge probes are mandatory every sample (check #6 below) — a service-scoped deploy can still cascade the reverse proxy.
- Store raw query output in files; only summaries into bead notes / tmux messages.
- Do not close the anchor bead unless the orchestrator explicitly assigned closure authority.
Deploy-gap guard — before the first sample
Prefer the shipped helper when on PATH:
verify-deploy-applied <container> <pr-number> <owner/repo>
Fallbacks:
docker inspect --format '{{.Name}} {{.State.StartedAt}} {{.Image}}' <container>
kubectl rollout status deployment/<name> --timeout=10m
bin=$(readlink -f "$(command -v <cmd>)"); repo=$(git -C "$(dirname "$bin")" rev-parse --show-toplevel)
git -C "$repo" fetch -q origin
git -C "$repo" merge-base --is-ancestor <mergeSha> HEAD
git -C "$repo" rev-list --count HEAD..origin/main
git -C "$repo" ls-files --error-unmatch "$bin"
Committed-artifact trap — xt resolves to dev/core/cli/dist/index.cjs, xtmux to dev/xtmux/bin/tmux-session-picker. Nothing is running, so verify-deploy-applied has nothing to inspect and the guard passes on a deploy that never happened. When the artifact is committed, git pull is the deployment — no rebuild. When it is not committed, the orchestrator must rebuild before the window; /update-xt carries the caveat that building from .xtrm/worktrees/* contaminates dist with absolute paths.
docker-compose .env trap — a fresh StartedAt isn't proof of a healthy deploy. docker compose up from a CWD without .env (worktrees, cron scripts) silently interpolates ${VAR} refs to empty strings. Reject:
docker compose up -d <svc> from .xtrm/worktrees/* (worktrees are gitignored → no .env).
docker compose --project-directory <path> up ... (that flag does NOT auto-load .env; only cd or --env-file does).
Safe: cd /path/to/infra && docker compose up -d --force-recreate <svc> OR pass --env-file explicitly. If unsure: docker exec <svc> env | grep -E '<REQUIRED_VAR>' — any expected-set var empty → BLOCKED.
Absolute-time sampling plan
Default: 60 minutes, 12 scheduled health samples, every 5 minutes, T+5 → T+60. Optional T+0 baseline immediately after the deploy-gap guard passes.
Write the absolute UTC schedule into the log at window start:
Window start: 2026-07-03T12:15:00Z
Scheduled samples (5m cadence): 12:20Z, 12:25Z ... 13:15Z
Window end no earlier than: 2026-07-03T13:15:00Z
Before each sample: date -u +%Y-%m-%dT%H:%M:%SZ. If the current time is before the scheduled tick, wait.
What each sample checks
Use the PR-specific signal list first; then the generic order:
- Tempo / traces — service spans present, no new error spans, p50/p95 within target. Producer presence check:
docker exec <prom> wget -qO- 'http://tempo:3200/api/search/tag/service.name/values' | jq .tagValues. Do NOT trust list_services — it lags reality by minutes.
- Prometheus / alerts — no firing alerts for target, error rate steady, gauges within baseline.
- Grafana dashboards — panel URL / screenshot when human review helps.
- Direct API health —
/health, freshness, source-specific sanity.
- Direct DB queries — last resort, scoped, read-only.
- Public edge probes (mandatory every sample). Read hosts from
$XTRM_EDGE_PROBES (colon-separated), then ~/.xtrm/config/edge-probes.txt, then .xtrm/edge-probes.txt. For each: curl -sS -o /dev/null -w '%{http_code}' https://$host/. Compare against per-host baseline (# expected: 200 comments in the config). Any subdomain returning an unexpected code — especially all-404 across the board — is edge-wide and HOLDs immediately. Traefik dynamic-config regression: target-service metrics look green because no request reaches the target.
If observability paths are unreachable, BLOCKED is the honest verdict.
HOLD policy — page on the first abnormal sample
- Append
HOLD line to log + bead notes with symptom and evidence path.
- Immediately message the orchestrator and Judge.
- Re-sample failing signal after ~30s to distinguish transient flap from sustained regression.
- Continue or abort per orchestrator direction — do not silently wait for the next tick.
Special case — edge-wide 4xx blackout (check #6): first sample HOLD, page symptom "edge blackout" with subdomain → HTTP code table. Do not wait for a second sample.
bd update <bead> --notes "DEPLOY SAMPLE T+25m HOLD: <symptom>; evidence: <query-or-log-path>"
xtmux message-send --to <orchestrator> --bead <bead> --json --text "HOLD at T+25m: <symptom>"
xtmux message-send --to <judge> --bead <bead> --json --text "deploy HOLD at T+25m: <symptom>"
Evidence and reporting
Sample log path: .xtrm/deploy-monitor/<bead-or-service>-pr<N>-<sha>.md
Line shape: T+15m OK — artifact <StartedAt>; alerts=0; p95=<v>; freshness=<v>; evidence=<query/log/panel>
Final:
bd update <bead> --notes "DEPLOY VERDICT: PASS — 12 samples through T+60, artifact StartedAt > mergedAt, no sustained alerts; log <path>"
xtmux message-send --to <orchestrator> --bead <bead> --expects-reply=false --json \
--text "deploy verdict PR <N>: PASS — see bead/log"
Retrieval hierarchy
Prefer durable sources over live scraping:
xtmux message-get <messageKey> --json — the message that anchored a reply obligation.
xtmux agent-last <pane_id> --json — last completed turn on a pane.
sp result <job-id> --json — final specialist output.
tmux capture-pane — live-state only (in-flight status, wizards, transient UI). Never as final-result protocol.
Failure / escalation trigger
Escalate to orchestrator (not silently HOLD longer) when: pane context climbs past ~60% during a long window (run /compact between samples first), Codex/observability tool returns kilobytes per query and the summarizer fails, or verify-deploy-applied returns 2 (dependency error) — a BLOCKED verdict with the specific dep missing lets the orchestrator fix and reissue.
When NOT to use this skill
- Reviewing the PR itself →
/pr-reviewer owns merge-readiness; this skill owns "safe to have merged".
- Merging / reverting / redeploying → orchestrator authority; escalate.
- Missing observability treated as success →
BLOCKED, always.
- Burying raw logs in tmux messages — messages are one-line pointers.
