description	Watch Vercel deploys for [REPLACE: VERCEL_PROJECT] — alert on [REPLACE: ALERT_ON] in the last [REPLACE: LOOKBACK_HOURS] hours

${var} — Optional. Override the Vercel project slug. If empty, watches [REPLACE: VERCEL_PROJECT].

Today is ${today}. Watch Vercel deployments for [REPLACE: VERCEL_PROJECT] and alert on [REPLACE: ALERT_ON] within the last [REPLACE: LOOKBACK_HOURS] hours.

Required secrets

• VERCEL_TOKEN — personal access token from https://vercel.com/account/tokens. Read scope is enough.
• (optional) VERCEL_TEAM_ID — if the project lives under a team, set this so the API queries the right scope.

If either secret is missing, log DEPLOY_WATCH_NO_TOKEN and exit cleanly — never abort the workflow.

Steps

1. Resolve scope:

   PROJECT="${var:-[REPLACE: VERCEL_PROJECT]}"
   SCOPE_QS=""
   if [ -n "${VERCEL_TEAM_ID:-}" ]; then
     SCOPE_QS="&teamId=$VERCEL_TEAM_ID"
   fi
   

2. Fetch recent deploys — Vercel API v6 lists deployments for a project:

   SINCE_MS=$(( $(date -u +%s) * 1000 - [REPLACE: LOOKBACK_HOURS] * 3600 * 1000 ))
   URL="https://api.vercel.com/v6/deployments?projectId=$PROJECT&since=$SINCE_MS$SCOPE_QS&limit=20"
   curl -sf -H "Authorization: Bearer $VERCEL_TOKEN" "$URL" > .vercel-deploys.json || \
     echo "DEPLOY_WATCH_FETCH_FAIL: $?"
   

   Make every Vercel call in-run with ./secretcurl (write the key as {VERCEL_TOKEN} — a bare $VERCEL_TOKEN on the line is refused by the Bash permission layer). Read-only status checks and any irreversible action (e.g. triggering a deploy) both run in-run — the irreversible one as the skill's final, fail-closed action. Never defer a read.

3. Parse and classify — for each deploy, capture: uid, state (READY / ERROR / CANCELED / BUILDING / QUEUED), url, target (production / preview), creator, createdAt, meta.githubCommitMessage.

4. Apply the alert filter — [REPLACE: ALERT_ON] is one of:

   • production-failures → alert when target=production AND state in {ERROR, CANCELED}.
   • any-failures → alert on any state in {ERROR, CANCELED}.
   • slow-builds → alert when build time > 10× the last-week median for this project.
   • all → alert on every state transition (noisy — only useful while debugging the skill).

5. Compare against last-success baseline — if alerting on a failure, also fetch the most recent successful production deploy and include in the notification: "last green: [commit] · [N hours] ago".

6. Dedup — track alerted deploy UIDs in memory/topics/[REPLACE: SKILL_NAME]-alerted.json. Never re-alert for the same UID.

7. Notify on every new alert via ./notify:

   *Deploy alert — [REPLACE: VERCEL_PROJECT]*
   ${state}: ${commit_message}
   ${target} build by ${creator} · ${ago}
   Last green: ${last_green_commit} · ${last_green_ago}
   Inspect: https://vercel.com/${owner}/${PROJECT}/${uid}
   

8. Write a roll-up to output/articles/[REPLACE: SKILL_NAME]-${today}.md: total deploys, success/fail counts per target, average build time, list of failed UIDs with commit messages.

9. Log to memory/logs/${today}.md:

   ## [REPLACE: SKILL_NAME]
   - **Deploys (${LOOKBACK_HOURS}h)**: total=N, ready=X, error=Y, canceled=Z, building=W
   - **Alerts fired**: N (deduped from M raw matches)
   - **Status**: DEPLOY_OK | DEPLOY_QUIET (no deploys) | DEPLOY_ALERT | DEPLOY_DEGRADED
   

Network note

The Vercel API requires Authorization: Bearer {VERCEL_TOKEN}. A bare $SECRET on a command line is refused by the Bash permission layer, so make every Vercel call in-run with ./secretcurl (write the key as the {VERCEL_TOKEN} placeholder — it keeps the secret off the line). Both the read-only status checks and any irreversible action (like triggering a deploy) run in-run; the irreversible one goes last, as the skill's final fail-closed action. Never defer a read.

Constraints

• Dedup is non-negotiable. Re-running the same alert for the same deploy will train operators to mute the channel — once alerted, never again unless the deploy changes state.
• Production beats preview for alerting. A failed preview deploy is interesting but not urgent. Default to production-failures until the operator opts into more.
• Compare against baseline. A failed build means more when paired with "last green was 3 hours ago" than alone.
