description: Run every Iron Law stage and the drift detector suite. Use when the user wants the full project health snapshot, a CI gate, or to verify nothing regressed before committing. Add --strict to promote warn-severity drift findings to errors. Activate only when the connected project contains spec.yaml or the user explicitly names Cladding; ignore ordinary requests in uninitialized projects.

Cladding check

Run `clad check` from the project root. Runs the 15 Iron Law stages — Type / Lint / Drift / Commit / Arch / Secret / Unit / Coverage / Spec-conformance / Deliverable-smoke / Smoke / Performance / Visual / Audit / UAT — and aggregates the worst exit code.

  • `0` — every stage cleared or skipped clean.
  • `1` — at least one stage actually failed (fix-required).
  • `2` — every result is skip (no fail-required input on the project yet).

`--strict` promotes warn-severity drift findings to error, matching the CI / pre-publish gate. The Drift stage runs every active detector under `src/stages/detectors/` — `npm run build:plugin` Phase D recounts them and writes the integer into each plugin manifest (e.g. `plugins/claude-code/.claude-plugin/plugin.json`), so the number is never hand-maintained.

`--internal` shows stage codes (`stage_1.1`) instead of business names (`Type`). Default is the business-name surface; the audit log keeps internal ids regardless.

Gate economy (tiers)

Pick the cheapest tier that answers your question — the full pre-push suite is expensive and grows with the project:

  • `clad check --tier=pre-commit` — drift / arch / secret only (spec-vs-code, no full unit suite). Use for

fast inner-loop feedback while implementing.

  • `clad check --tier=pre-push --strict` — the full gate (type / lint / unit / cov + drift). This is what

`clad done <featureId>` already runs, so do NOT run it separately right before `clad done` — one authoritative full gate per feature, not two. A GREEN run refreshes `spec/attestation.yaml` with the running Cladding version, strict blocking mode, detector-catalog SHA-256, module hashes, and feature markers. See `docs/feature-cycle.md` § Gate economy.

For an organization to trust AI with its code, three things must hold — trust, traceability, and stability at scale. cladding wraps your AI coding agent: your intent goes in before it writes, and the result is verified against your spec after, so those three are earned, not assumed. First L4 implementation of the Ironclad standard.
