/launch-check — Production Readiness Audit
Runs a 10-dimension sweep against a project and outputs a one-page verdict. Designed for milestone boundaries — epic completion, release cuts, launch prep — not per-PR use.
Invoke from the project's workspace directory (cd workspace/<project>/) or pass the path as an argument: /launch-check workspace/my-app.
Three modes:
/launch-check [project-path] — full audit (default). Runs all 10 dimensions serially, persists results to the per-project history store, and renders a "Trend (last 5 runs)" section when ≥ 2 prior runs exist./launch-check trend [project-path] — read-only trend report. Renders just the trend section from existing run files. Useful for "are we trending up?" without burning the audit cost. See § "Trend-only mode" below./launch-check --workflow [project-path] — opt-in parallel + adversarially-verified audit. Fans the 10 dimensions out concurrently (one agent each), independently verifies every FAIL/WARN finding before it lands in the verdict, then synthesizes the same table and persists via the same history store. Faster wall-clock and fewer false positives; costs more tokens (spawns ~10–20 agents). Same output, same trend continuity — see § "Workflow mode" below.
Deep-dive companions
Each dimension has a dedicated expert skill for when you need to go deeper than the one-line summary. The launch check is the overview; the expert skills are the investigation.
| Dimension | Quick check | Deep dive |
|---|
| Security | /launch-check row 1 | /threat-model — full STRIDE threat modelling exercise |
| Accessibility | /launch-check row 2 | /accessibility-audit — WCAG 2.1 AA compliance audit |
| Compliance | /launch-check row 3 | /compliance-check — GDPR + ePrivacy analysis |
| Analytics | /launch-check row 4 | /analytics-audit — event taxonomy and funnel coverage |
| SEO | /launch-check row 5 | /seo-audit — technical SEO against Google best practices |
| Generative-engine | /launch-check row 6 | /geo-audit — LLM/agent discoverability (GEO + AEO), llms.txt, AGENTS.md, AI-crawler directives, JSON-LD citation grounding |
| Performance | /launch-check row 7 | /performance-audit — bundle, images, Core Web Vitals |
| Monitoring | /launch-check row 8 | /monitoring-audit — observability and incident readiness |
| Documentation | /launch-check row 9 | /docs-audit — Diataxis framework completeness |
| Behaviour quality | /launch-check row 10 | /mutation-test — mutation-testing sensor; measures whether the test suite constrains behaviour, not just executes lines |
When a dimension shows WARN or FAIL, tell the user: "For a detailed analysis, run /threat-model" (or the relevant expert skill).
Output format
The output should be scannable in 10 seconds. One table, one verdict, one blockers list:
LAUNCH CHECK — <project> @ <sha> (<date>)
| # | Dimension | Status | Finding |
|----|--------------------|--------|--------------------------------------|
| 1 | Security | PASS | No critical vulns, auth flow ok |
| 2 | Accessibility | WARN | 3 images missing alt text |
| 3 | Compliance | FAIL | No cookie consent banner detected |
| 4 | Analytics | PASS | GA4 configured, 12 events tracked |
| 5 | SEO | WARN | Missing og:image on 2 pages |
| 6 | Generative-engine | WARN | No llms.txt, AGENTS.md missing |
| 7 | Performance | PASS | Bundle < 200KB, LCP < 2.5s |
| 8 | Monitoring | FAIL | No health check endpoint found |
| 9 | Documentation | PASS | README updated this week |
| 10 | Behaviour quality | WARN | Mutation score 54% (threshold 60%) |
Verdict: CONDITIONAL GO (2 failures need resolution)
Blocking:
- [ ] Add cookie consent banner (compliance)
- [ ] Add /health endpoint (monitoring)
Warnings (non-blocking, address before next launch):
- [ ] Add alt text to 3 images (accessibility)
- [ ] Add og:image to landing and pricing pages (SEO)
Do NOT dump hundreds of lines. Each dimension gets ONE row in the table. Details go in follow-up messages only if the user asks "tell me more about the security findings" — not upfront.
Verdict logic
| Condition | Verdict |
|---|
| All dimensions PASS | GO — ready to launch |
| Some WARN, zero FAIL | GO with warnings — launch is safe, address warnings before next milestone |
| Any FAIL | CONDITIONAL GO — resolve the blocking items before launch |
| 3+ FAIL or any critical security finding | NO-GO — significant gaps, not launch-ready |
The 9 dimensions
1. Security
What to check:
- Run
npm audit / pip audit / equivalent for dependency vulnerabilities
- Grep for hardcoded secrets, API keys, tokens (same patterns as
check-secrets.sh but against the full codebase, not just staged files)
- Check auth flow: is there authentication? Is it using a reputable provider (Cognito, Auth0, Firebase Auth)? Are tokens stored securely (httpOnly cookies, not localStorage)?
- Check for common OWASP risks: SQL/NoSQL injection surfaces, XSS vectors (dangerouslySetInnerHTML, v-html), CSRF protection
- Check HTTPS enforcement, CORS configuration, security headers
PASS if: no critical vulns, auth uses a reputable provider, no hardcoded secrets, basic OWASP surface clean.
WARN if: medium vulns in dependencies, or missing security headers.
FAIL if: critical vuln, hardcoded secrets found, no auth on a user-facing app, or obvious injection surface.
2. Accessibility
What to check:
- Grep for
<img tags without alt attributes
- Check for semantic HTML:
<main>, <nav>, <header>, <footer>, heading hierarchy (h1 → h2 → h3)
- Check for
aria-label on interactive elements without visible text
- Check color contrast: look for low-contrast color combinations in CSS/theme files
- Check keyboard navigation: are there
onClick handlers without corresponding onKeyDown?
- Check for
<html lang="..."> attribute
PASS if: all images have alt text, semantic HTML used, no obvious contrast issues.
WARN if: a few missing alt texts, or minor semantic gaps.
FAIL if: systematic missing alt text, no semantic HTML at all, or no lang attribute.
3. Compliance
What to check:
- Cookie consent: grep for cookie-consent libraries (cookieconsent, react-cookie-consent, etc.) or a consent banner component
- Privacy policy: check for a
/privacy route or privacy-policy page
- Terms of service: check for a
/terms route
- GDPR: if the app collects user data, is there a data deletion mechanism? Check for a "delete account" route or endpoint
- Data retention: is there a documented policy? (Can be in docs/ or in the privacy policy)
PASS if: cookie consent present, privacy policy exists, terms exist.
WARN if: privacy policy exists but no data deletion mechanism.
FAIL if: no cookie consent on a site that uses cookies, or no privacy policy on a user-facing app.
4. Analytics
What to check:
- Grep for analytics SDK initialization (Google Analytics/GA4, Mixpanel, Amplitude, PostHog, Plausible)
- Check for event tracking calls (gtag, track, capture, etc.)
- Check for a config file or environment variable pointing to an analytics dashboard
- If no analytics at all and the project is user-facing: that's a finding
PASS if: analytics SDK configured and events are being tracked.
WARN if: SDK configured but few/no custom events (only page views).
FAIL if: user-facing app with zero analytics. (Non-user-facing like CLIs/libraries: auto-PASS.)
5. SEO
What to check:
- Check for
<title> and <meta name="description"> on key pages
- Check for
<meta property="og:title">, og:description, og:image (Open Graph)
- Check for
sitemap.xml at the expected location
- Check for
robots.txt
- Check for canonical URLs (
<link rel="canonical">)
- Check for structured data (JSON-LD, schema.org)
PASS if: title + description + OG tags on main pages, sitemap exists, robots.txt exists.
WARN if: missing OG tags on some pages, or no structured data.
FAIL if: no title/description on the main page, or no robots.txt. (Non-web projects: auto-PASS.)
6. Generative-engine (LLM/agent discoverability)
What to check (quick scan — full deep-dive lives in /geo-audit):
llms.txt and llms-full.txt at the site rootAGENTS.md at the repo root- AI-crawler directives in
robots.txt (does it name GPTBot, ClaudeBot, PerplexityBot, etc.?)
- JSON-LD citation metadata on article-shaped pages (
author, dateModified, datePublished, publisher)
- Per-page token count for the largest docs page (heuristic:
char_count / 4 — flag pages over 25K)
Covers two related sub-scopes: GEO (LLM citations — ChatGPT, Claude, Perplexity, Gemini) and AEO (coding-agent consumption — Claude Code, Cursor, Aider, Cline). Both consume the same artefacts, so they share one row at the milestone-boundary level. For the bucket-by-bucket breakdown, run /geo-audit.
PASS if: llms.txt present, AGENTS.md present with sandbox + MCP sections, JSON-LD citation metadata on key pages.
WARN if: some artefacts missing (e.g. AGENTS.md exists but lacks sandbox links).
FAIL if: no llms.txt AND no AGENTS.md AND no citation JSON-LD on a content-heavy site. (Non-web projects: auto-PASS.)
7. Performance
What to check:
- If there's a build output: check bundle size (look for
dist/, build/, .next/)
- Check for image optimization: are images served as WebP/AVIF? Are there large unoptimized images (> 500KB)?
- Check for lazy loading on below-the-fold images (
loading="lazy")
- Check for code splitting (dynamic imports, React.lazy)
- If there's a Lighthouse config or Web Vitals tracking: check the targets
PASS if: bundle under 300KB gzipped, images optimized, lazy loading present.
WARN if: bundle 300-500KB, or a few large images.
FAIL if: bundle > 1MB, or systematically unoptimized images. (Non-web: auto-PASS.)
8. Monitoring
What to check:
- Grep for error tracking SDK (Sentry, Datadog, Bugsnag, LogRocket)
- Check for a health check endpoint (
/health, /healthz, /api/health)
- Check for alerting configuration (PagerDuty, OpsGenie, CloudWatch Alarms, or alerting rules in code)
- Check for a runbook or incident response doc (
docs/runbook.md, docs/incident-response.md)
- Check for logging configuration (structured logging, log levels)
PASS if: error tracking configured, health endpoint exists, some alerting in place.
WARN if: error tracking but no health endpoint, or no runbook.
FAIL if: no error tracking at all on a production app, or no health endpoint.
9. Documentation
What to check:
- README.md exists and is not the default template
- README has: project description, setup instructions, how to run locally, how to deploy
- API documentation: if there's an API, is it documented? (OpenAPI spec, Swagger, or doc comments)
- Deployment guide: how to deploy to staging/production
- Changelog: is there a CHANGELOG.md or are releases documented?
- Check for staleness: compare README last-modified date with recent code changes
PASS if: README has setup + run + deploy instructions, and was updated recently.
WARN if: README exists but is stale (> 30 days behind code changes), or API undocumented.
FAIL if: no README, or README is the default GitHub template.
10. Behaviour quality (mutation testing)
What to check (quick gate — full deep-dive lives in /mutation-test):
- Read
.claude/project-config.json → mutation.threshold (default 60% from .claude/project-config.defaults.json)
- Check whether a recent mutation report exists at
projects/<name>/quality/mutation-<YYYY-MM-DD>.md (within the last 30 days)
- If the latest report's score < threshold → WARN (not FAIL — mutation is a leading indicator, not a launch blocker)
- If no recent report exists, offer to dispatch to
/mutation-test for a fresh run, but do NOT auto-run it during /launch-check. A mutation audit takes 20–40 minutes on a medium codebase — too slow to fold into the milestone-boundary sweep silently. The dimension reports WARN with the finding "no recent mutation report (run /mutation-test for a fresh number)".
- If
mutation.runner is null or the project's primary language has no recognised mutation runner installed: auto-PASS (the audit doesn't apply — same shape as SEO auto-PASS for non-web projects). Surface the gap as INFO in the finding column.
PASS if: recent mutation report exists AND score ≥ threshold.
WARN if: recent mutation report exists BUT score < threshold, OR no recent report (operator should run /mutation-test).
FAIL if: never — mutation testing is advisory, not a launch blocker. See AgDR-0045 for the rationale.
Auto-PASS for projects without a mutation runner installed (or where the language has no recognised dispatch — e.g. Rust at v1).
Process
Step 1: Determine the project
If invoked with an argument, use that path. Otherwise, use the current working directory. Verify it's a git repo with source code (not the ops repo itself — the launch check is for managed projects, not for apexyard).
Step 2: Quick scan
Read the project's structure to determine what checks apply:
- Is it a web app? (has
index.html, React/Vue/Svelte/Next.js markers) → all 9 dimensions
- Is it an API only? (has routes/endpoints but no frontend) → skip accessibility, SEO, generative-engine, performance (auto-PASS)
- Is it a CLI/library? → skip accessibility, compliance, analytics, SEO, generative-engine, performance (auto-PASS on those)
- Is it a mobile app? → adjust accessibility checks for mobile, skip SEO, skip generative-engine
Step 3: Run each applicable dimension
Go through each dimension in order. For each:
- Run the checks listed above (grep, file existence, SDK detection)
- Classify as PASS / WARN / FAIL based on the criteria
- Write a one-line finding for the table
Do NOT spend more than 30 seconds per dimension. The checks should be quick grepping and file scanning, not deep code review. Deep dives happen in the dedicated companion skill (/seo-audit, /geo-audit, /threat-model, etc.) — not inside the initial sweep.
Step 4: Compile the verdict
Count PASS/WARN/FAIL, apply the verdict logic, format the output table.
Step 5: Output
Print the table exactly as shown in the "Output format" section above. Then continue to Step 6 to persist the run and render the trend section.
Do NOT auto-create tickets for the findings. Offer: "Want me to create tickets for the blocking items?" — but let the user decide. The launch check is advisory.
Workflow mode (--workflow) — opt-in parallel + adversarial verify
When invoked as /launch-check --workflow [project-path], replace the serial Steps 3–5 with a single Workflow tool invocation that fans the 10 dimensions out concurrently and adversarially verifies the findings, then resume at Step 6 (persist) unchanged. Steps 1–2 (resolve project + detect stack) and Step 6 (persist + trend) are identical to the default path — only the evaluation of the 10 dimensions changes from serial to fanned-out.
Why a Workflow here (and why opt-in)
The 10 dimensions are independent and read-only — no shared writes, no cross-dimension data dependency, no human gate. That's the canonical fan-out shape: evaluate all 10 in parallel, then have an independent skeptic try to refute each FAIL/WARN before it reaches the verdict (the false-positive killer). The trade-off is token cost — a workflow run spawns ~10–20 agents versus one serial pass — so this is opt-in, never the default. Rationale: AgDR-0055.
Prerequisite: the Workflow tool requires explicit opt-in to multi-agent orchestration. The --workflow flag is that opt-in — when the operator passes it, author and run the workflow below. Without the flag, run the serial path and do NOT invoke Workflow.
The canonical workflow script
Author and run this via the Workflow tool (adapt the project name / stack-skip set from Steps 1–2). The dimension prompts reuse the exact PASS/WARN/FAIL criteria from "The 9 dimensions" / row-10 below — do not invent new criteria. Auto-PASS the not-applicable dimensions per the existing rules (e.g. SEO/GEO/perf auto-PASS for a non-web project, analytics auto-PASS for a CLI/library) by passing them as already-resolved rather than spawning an agent.

return res
})
},
)
return { results: [...preResolved, ...evaluated.filter(Boolean)] }
After the workflow returns
- Take
results[] (one row per dimension, each with status / score / finding).
- Count PASS/WARN/FAIL, apply the same verdict logic ("Verdict logic" table above) — go / go-with-warnings / conditional-go / no-go.
- Print the same verdict table as the serial path (Step 5 "Output format").
- Persist via Step 6 unchanged — build the same superset payload (
scores{} from each row's score, findings[] from the WARN/FAIL rows), call audit_run_persist, then audit_render_trend. The history store, schema, and render-trend.sh chart are identical to a serial run, so trend continuity is preserved across serial↔workflow runs.
Degrade gracefully
If the Workflow tool is unavailable in the current Claude Code installation, say so in one line and fall back to the serial Steps 3–5. The audit must still complete — --workflow is an optimisation, not a hard dependency.
Step 6: Persist the run + render the trend
After the verdict table, persist this run to the project's history store via the shared audit-history lib and append a trend section if there are ≥ 2 prior runs.
This step was refactored as part of #218 to consume _lib-audit-history.sh (the same lib that powers /threat-model, /security-review, and the other audit skills). Behaviour is preserved: the JSON schema is the same superset shape, the chart is rendered by the same render-trend.sh (dispatched from inside the lib), and adopters' existing run-history at the legacy path is still picked up by the trend renderer.
6a. Resolve project name + score + verdict
<project-name> is the project's registered name in apexyard.projects.yaml. If the project isn't registered (e.g. someone runs /launch-check on a directory that's never been onboarded), use the basename of the project path; tell the operator to /handover it for cross-machine trend continuity.
The headline score is the unweighted mean of scores.*, rounded to int. The verdict is one of go / go-with-warnings / conditional-go / no-go (launch-check-specific four-state vocabulary, preserved from the existing skill).
6b. Build payload + body, persist via the lib
The lib's audit_run_persist accepts arbitrary stdin JSON and augments it with top-level ts / dimension / verdict / score fields, then writes both a JSON file and an MD file. For launch-check the JSON payload is a SUPERSET — it includes the legacy scores{} map (for render-trend.sh to plot) AND a derived findings[] array (for the canonical schema):
source "$(git rev-parse --show-toplevel)/.claude/hooks/_lib-audit-history.sh"
payload=$(mktemp); cat > "$payload" <<'EOF'
{
"schema_version": 1,
"branch": "main",
"commit": "abc1234",

}

audit_run_persist "<project-name>" "launch-check" "$ts" "conditional-go" 84 "$body" < "$payload"
rm -f "$payload" "$body"
audit_run_persist writes:
projects/<name>/audits/launch-check/runs/<ts>.json — JSON with everything the lib added on top of the payload (top-level ts, dimension: launch-check, verdict, score, schema_version) AND everything in the original payload (scores{}, branch, commit, top_risks[], findings[], derived stats{})projects/<name>/audits/launch-check/<ts>.md — frontmatter + the body aboveprojects/<name>/audits/launch-check/.gitignore — driven by the per-dim .audit-history-tracked marker presence
JSON schema is a SUPERSET. The canonical fields (ts, dimension, verdict, score, findings[], stats{}, schema_version) coexist with the launch-check-specific fields (scores{}, branch, commit, top_risks[]). The legacy render-trend.sh reads ts / scores / verdict and works unchanged. The new generic audit_render_trend reads ts / score / verdict and works for the rest of the audit family.
6c. Render the trend section
audit_render_trend "<project-name>" "launch-check" 5
- The lib internally dispatches to
render-trend.sh for the launch-check dimension — byte-equal output to the pre-#218 chart (mean of scores.* on Y-axis, score-delta notes, ASCII chart).
- Crucially, the lib's
audit_run_list merges JSON from the canonical path (projects/<name>/audits/launch-check/runs/) AND the legacy path (projects/<name>/launch-check/runs/) — so adopters' existing history continues to render across the migration. No mv required.
- Output is a markdown trend block (heading + table + ASCII chart). Append it to this run's MD artefact and to the chat output.
6d. Opt-in commit (history-tracked marker)
The per-dimension marker (.audit-history-tracked) sits inside the dimension's audit dir and controls whether runs/*.json files are gitignored:
touch projects/<name>/audits/launch-check/.audit-history-tracked
The lib re-evaluates the marker on every persist; toggling is free. The MD artefact at <dim_dir>/<ts>.md is committed regardless — that's the durable human-readable artefact.
Migration note for adopters with existing history: the legacy marker at projects/<name>/launch-check/.launch-check-history-tracked continues to apply to that path's runs/. To consolidate trees, mv projects/<name>/launch-check/* projects/<name>/audits/launch-check/ after backing up; the lib's renderer will read the consolidated tree on the next run. Consolidation is optional — the read-merge happens transparently if you leave both trees in place.
Trend-only mode — /launch-check trend [project-path]
Read-only mode that produces just the trend section (no full audit, no per-dimension grep). Useful for "are we trending up?" without re-running the costly sweep.
Process:
- Source
_lib-audit-history.sh (same as Step 6).
- Call
audit_render_trend "<project-name>" "launch-check" 5. The lib reads both the canonical path AND the legacy path; if the merged set has < 2 runs the call is silent and you tell the operator there's no trend yet.
- Print the renderer's output.
Do NOT run the 9-dimension sweep in this mode. Do NOT write any new JSON. This mode is purely for reviewing existing history.
Rules
- Scannable in 10 seconds. One table, one verdict, one blockers list. No walls of text.
- One row per dimension. Details on demand, not upfront.
- 30 seconds per dimension. Quick grep and file scanning, not deep code review.
- Auto-PASS non-applicable dimensions. A CLI doesn't need a cookie banner.
- Advisory, not blocking. The user decides go/no-go based on the findings. The skill does NOT block deploys mechanically.
- Don't create tickets unprompted. Offer to create them. Let the user decide.
- Run from the project directory. The skill checks
workspace/<project>/, not the ops repo.
- Persist every run via the lib. Step 6 always calls
audit_run_persist, regardless of opt-in commit state. The .audit-history-tracked marker only controls whether the JSON files are committed; the MD artefacts are committed unconditionally and persistence happens on every run.
- Resolve paths via the lib.
audit_resolve_dir (inside _lib-audit-history.sh) calls portfolio_projects_dir for you — the SKILL doesn't need to source the portfolio helper directly any more.
Implementation notes
Persistence + trend logic ships as a shared shell helper that all audit skills consume:
| File | Purpose |
|---|
.claude/hooks/_lib-audit-history.sh | Audit-history library shared with /threat-model, /security-review, etc. (4 functions: audit_resolve_dir, audit_run_persist, audit_run_list, audit_render_trend) |
render-trend.sh (this skill's dir) | Legacy chart renderer for the launch-check dimension; the lib's audit_render_trend dispatches to it when the dimension is launch-check so the chart shape stays byte-equal across the #218 refactor |
