| 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 ${today}. Watch Vercel deployments for [REPLACE: VERCEL_PROJECT] and alert on [REPLACE: ALERT_ON] within the last [REPLACE: LOOKBACK_HOURS] hours.
Required secrets
VERCEL_TOKEN — personal access token from https://vercel.com/account/tokens. Read scope is enough.
- (optional)
VERCEL_TEAM_ID — if the project lives under a team, set this so the API queries the right scope.
If either secret is missing, log DEPLOY_WATCH_NO_TOKEN and exit cleanly — never abort the workflow.
Steps
-
Resolve scope:
PROJECT="${var:-[REPLACE: VERCEL_PROJECT]}"
SCOPE_QS=""
if [ -n "${VERCEL_TEAM_ID:-}" ]; then
SCOPE_QS="&teamId=$VERCEL_TEAM_ID"
fi
-
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 read-only status calls in-run with ./secretcurl (write the key as {VERCEL_TOKEN} — a bare $VERCEL_TOKEN on the line is refused by the Bash permission layer). Reserve the post-process pattern — write a .pending-deploy-watch/check.json request and add a scripts/postprocess-deploy-watch.sh that runs after the Claude step — for the irreversible action (triggering a deploy), never for reads.
-
Parse and classify — for each deploy, capture: uid, state (READY / ERROR / CANCELED / BUILDING / QUEUED), url, target (production / preview), creator, createdAt, meta.githubCommitMessage.
-
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).
-
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".
-
Dedup — track alerted deploy UIDs in memory/topics/[REPLACE: SKILL_NAME]-alerted.json. Never re-alert for the same UID.
-
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}
-
Write a roll-up to output/articles/[REPLACE: SKILL_NAME]-${today}.md: total deploys, success/fail counts per target, average build time, list of failed UIDs with commit messages.
-
Log to memory/logs/${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 the read-only status calls in-run with ./secretcurl (write the key as the {VERCEL_TOKEN} placeholder — it keeps the secret off the line). Reserve the post-process pattern in CLAUDE.md (write request JSON to .pending-deploy-watch/, then scripts/postprocess-deploy-watch.sh runs after Claude with full env) for any irreversible action like triggering a deploy — never for reads.
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.
