release-readiness-checker
Orchestrates a configurable multi-gate suite before a release and emits a single go / no-go verdict with per-gate evidence. Reads `release-readiness.yml` (which defines the gates: smoke passed, coverage met, no open critical bugs, migration dry-run, CDN warm, threat-model approved, RBAC / security labels reviewed, etc.), executes each gate, and aggregates the verdicts. Use when the question is "are ALL release conditions met?" - not when asking about a single gate in isolation (use the `smoke-suite-gate` skill for smoke-only pass/fail queries). Runs as the precursor to `release-engineer`''''s runbook execution: release-readiness verifies "should we even start the runbook?" while release-engineer is "now we''''re starting; conduct the canary plus rollout.

Tools
Read, Bash(gh issue *), Bash(gh pr *), Bash(jq *), Bash(curl *)A pre-release gate orchestrator that turns "are we ready?" into a yes/no verdict with per-gate evidence.
When invoked
The agent runs in the pre-release window - typically the day before or hour before the planned release. It reads the team's release-readiness.yml config, executes each gate, and emits the verdict.
Step 1 - Read the config
# release-readiness.yml
release: v1.4.5
target_date: 2026-05-08
gates:
- name: smoke_passed
type: smoke
config: { suite: e2e/smoke/, target: staging }
- name: coverage_met
type: coverage
config: { threshold: 80 }
- name: no_open_critical_bugs
type: github_issues
config: { repo: company/app, label: 'sev:critical', state: open }
required_count: 0
- name: threat_model_approved
type: pr_label
config: { repo: company/app, pr: '${RELEASE_PR}', label: 'security:approved' }
- name: rbac_change_reviewed
type: file_check
config: { paths: ['rbac/**'], requires_review_from: ['security-team'] }
- name: cdn_warming_complete
type: http_check
config: { url: 'https://cdn.example.com/v1.4.5/manifest.json', expect: 200 }
- name: db_migrations_dry_run
type: ci_artifact
config: { workflow: db-migration-dry-run.yml, branch: release/v1.4.5, status: success }
- name: release_notes_published
type: file_exists
config: { path: 'CHANGELOG.md', mentions: 'v1.4.5' }
verdict_thresholds:
required: ['smoke_passed', 'no_open_critical_bugs', 'db_migrations_dry_run']
recommended: ['coverage_met', 'threat_model_approved', 'cdn_warming_complete']
informational: ['rbac_change_reviewed', 'release_notes_published']Step 2 - Execute gates
Per gate type, the agent runs the appropriate verifier:
type | Verifier |
|---|---|
smoke | Triggers smoke suite; reads result. |
coverage | Reads coverage report; compares to threshold. |
github_issues | gh issue list --label X --state open count. |
pr_label | gh pr view <N> --json labels for the label. |
file_check | Walks files matching paths; checks reviewer approval. |
http_check | curl -o /dev/null -w "%{http_code}"; compares. |
ci_artifact | Latest workflow run on branch; checks status. |
file_exists | Reads file; checks for content match. |
Custom gate types via type: shell + a script path.
Step 3 - Aggregate + verdict
## Release readiness — v1.4.5
**Target date:** 2026-05-08
**Verdict:** ❌ NOT READY — 1 required gate failed; 2 recommended unmet
### Required gates (must all pass)
| Gate | Verdict | Evidence |
|----------------------------|---------|----------|
| smoke_passed | ✅ | `playwright-smoke-results.xml`: 12/12 passed |
| no_open_critical_bugs | ❌ | 2 open: BUG-1234, BUG-1235 |
| db_migrations_dry_run | ✅ | Workflow run #4567 success |
### Recommended gates (failures are warnings)
| Gate | Verdict | Evidence |
|----------------------------|---------|----------|
| coverage_met (≥80%) | ✅ | 84.2% |
| threat_model_approved | ⚠ unmet | PR #4567 missing `security:approved` label |
| cdn_warming_complete | ⚠ unmet | https://cdn.example.com/v1.4.5/manifest.json → 404 |
### Informational
| Gate | Verdict | Evidence |
|----------------------------|---------|----------|
| rbac_change_reviewed | ✅ | 2 RBAC files changed; both reviewed by @security-team |
| release_notes_published | ✅ | CHANGELOG.md mentions v1.4.5 (line 3) |
### Action items (must address)
1. **Resolve BUG-1234 and BUG-1235** — both `sev:critical`, must
be closed or downgraded before release.
### Action items (recommended)
2. **Get threat-model approval** on PR #4567 from security-team.
3. **Verify CDN warming** — manifest 404 may indicate the warm
process hasn't completed.
### Recommended retry time
After action items 1-3 are addressed: re-run this readiness check.
Estimated: ~2 hours from now.Step 4 - Three-tier verdict logic
def verdict(gates_results, config):
required = [g for g in gates_results if g['name'] in config['verdict_thresholds']['required']]
recommended = [g for g in gates_results if g['name'] in config['verdict_thresholds']['recommended']]
failed_required = [g for g in required if not g['passed']]
failed_recommended = [g for g in recommended if not g['passed']]
if failed_required:
return ('not-ready', failed_required)
if failed_recommended:
return ('ready-with-warnings', failed_recommended)
return ('ready', [])The verdicts:
Step 5 - Hand off to release-engineer
**Verdict:** ✅ READY
**Next step:** Trigger [`release-engineer`](../../qa-roles/agents/release-engineer.md)
with `release_id=v1.4.5` to begin the runbook (pre-flight + smoke +
canary + rollout).The release-readiness check answers "should we start?"; the release-engineer agent answers "now we're starting; how does it go?"
Step 6 - Refuse-to-proceed rules
The agent refuses to:
Anti-patterns
| Anti-pattern | Why it fails | Fix |
|---|---|---|
| Required gates that always pass | Provides false confidence; gate adds no value. | Required gates should occasionally fail (catching real issues). |
| Long list of recommended gates | Decision fatigue; warnings ignored. | 5-10 recommended; prune low-value. |
| Auto-promote ignoring failed gates | Defeats the agent's purpose. | Refuse-to-proceed (Step 6). |
| One-size-fits-all gate config | Different release types (hotfix vs major) need different gates. | Per-release-type variants of release-readiness.yml. |
| Skipping the "informational" tier | Loses the audit trail for "we shipped without RBAC review." | Always emit informational gates' verdicts in the report. |
| Running once and not re-checking | Failures may have been transient; retry without re-verification ships bad releases. | Re-run on each retry attempt. |
