About

/ccc-harden — Production Hardening Audit

Audit a site across 11 hardening pillars to confirm it's safe to ship. Read-only by default. Apply safe auto-fixes with --fix.

What it checks

| Pillar | What it verifies | |--------|-----------------| | 1. Vercel | Project link, env vars, deploy headers, deploy protection, domain | | 2. GitHub Linkage | Remote URL, branch tracking, .gitignore coverage, working tree clean | | 3. GitHub Org | Branch protection on main, Dependabot enabled, secret scanning, CODEOWNERS | | 4. Sentry | SDK installed, DSN set, source maps uploading, alert rules, sample rate | | 5. PostHog | SDK installed, env vars set, autocapture config, event whitelist | | 6. Plausible | Script present, site ID, goals, funnels, recent traffic | | 7. Clarity | Script presence, project ID | | 8. Google | GA4, Search Console verified, sitemap submitted, Tag Manager | | 9. Stripe | Keys present, webhook configured, test/live separation | | 10. Secrets & PII | gitleaks scan, CSP/HSTS/X-Frame headers, .env audit, log scrubbing | | 11. Cloudflare | DNS health, TLS/SSL, bot management, caching, HTTP/3, WAF |

When to use

Use when:

  • Pre-launch checklist for a new site
  • Before a security review or compliance audit
  • Periodic monthly/quarterly health check
  • After a major refactor that touched config files
  • When you suspect a leaked secret

🚫 Don't use when:

  • Project is pre-MVP / local-only (overkill)
  • Quick fix that doesn't touch infra/config (use /ccc-doctor instead)

Trigger flow

When the user invokes /ccc-harden:

  1. Read .harden.json at project root. If missing, run bash ~/.claude/skills/harden-site/lib/tier.sh to auto-classify (production/staging/parked/personal) and generate it.
  1. Ask the user via AskUserQuestion which mode:
  • Audit only (read-only, default — recommended)
  • Apply auto-fixes (writes to vercel.json, .gitignore, etc.)
  • Single pillar (pick from list of 11)
  1. Run pillars based on .harden.json enabled list:

``bash for pillar in ~/.claude/skills/harden-site/pillars/*.sh; do name=$(basename "$pillar" .sh | sed 's/^[0-9]*-//') enabled=$(jq -r ".pillars[\"$name\"]" .harden.json) [ "$enabled" = "true" ] && bash "$pillar" --audit done ``

  1. Aggregate results into a single summary:
  • Total checks · pass · warn · fail · skipped
  • Top 5 manual actions required
  • Top 5 auto-fixable items
  • Severity-ranked (CRITICAL → HIGH → MEDIUM → LOW)
  1. Offer next step via AskUserQuestion:
  • Apply auto-fixes now (re-runs with --fix)
  • Show full report (paginated output of all pillars)
  • Create Linear issues for manual actions
  • Done — I'll triage manually

Privacy guarantee (NO PII)

CC Commander's hardening audit never sends data to PostHog or any telemetry endpoint. Every check is:

  • Local-only (reads files, runs gh/vercel/fly/op CLIs)
  • Reports rendered in the terminal
  • Findings written to .harden.report.md (gitignored by default)

Telemetry from /ccc-harden itself emits only:

  • skill_invoked with skill_id=ccc-harden
  • harden_audit_completed with { tier, pillars_run, pass, warn, fail } (counts only, no file paths, no findings)

Zero PII. Zero secrets. Zero file content. Ever.

Exit behavior

| Result | Exit | Next action | |--------|------|-------------| | All pass | 0 | "✅ Ready to ship." | | Warnings only | 1 | "🟡 Review warnings before launch." | | Failures | 2 | "🔴 Block launch until fixes applied." | | Missing tokens | 3 | "⏭️ Pillar skipped — set up op access." |

Setup (first run)

If the user has never run hardening before:

  1. Auto-classify the project: bash ~/.claude/skills/harden-site/lib/tier.sh
  2. Edit .harden.json to enable/disable pillars per their stack
  3. For pillars that need API tokens (Vercel, Cloudflare, PostHog management API):
  • Verify tokens in 1Password Alfred vault (see ~/.claude/skills/harden-site/TOKENS.md)
  • Run op signin if not already authenticated
  1. First run is read-only — always show what would change before fixing

Related skills

  • /ccc-doctor — generic project health check (lighter weight, no API tokens)
  • /ccc-security — OWASP audit + threat modeling (deeper than infra hardening)
  • /ccc-deploy-check — pre-deploy gate (12 quick checks before pushing)
  • /ccc-deploy — actual deploy workflow (uses hardening output as a precondition)

Vendor sources

This skill wraps ~/.claude/skills/harden-site/ (Kevin's site-hardening skill, a fork of the upstream "harden" pattern). The 11 pillars and auto-fix logic live there; this plugin skill is the UX layer that makes them discoverable inside CC Commander.

To update the underlying logic, edit ~/.claude/skills/harden-site/pillars/*.sh — this skill re-reads them every invocation.
