extract-ds-skill

Execute a unit of work end-to-end: understand, implement, validate with typecheck and build, then commit. Use when the user wants to do work, build a feature, fix a bug, or implement an issue or phase from a plan. Do NOT use for design-system skill extraction — that flow has its own meta-skill (extract-ds-skill).

produced-skill

Test fixture — produced-skill mode, ships a references/design-craft.md that was paraphrased during persist instead of copied verbatim (a NEVER dropped, a MUST softened). DESIGN_CRAFT must FAIL on the byte-diff and cite craft/regenerated-not-copied.

Test fixture — meta-skill self-mode, full three-phase shape but missing the per-phase handoff-emission prose. HANDOFF_EMISSION must report FAIL.

Test fixture — meta-skill self-mode. discovery.md handoff template carries both required sections but hedges a foundation sub-page with "if confirmed". HANDOFF_COMPLETENESS must report FAIL (state/handoff-out-of-scope-deferred).

Test fixture — meta-skill self-mode. discovery.md handoff template has a `## Decisions` block but NO `## Components proposed` section. HANDOFF_COMPLETENESS must report FAIL (state/handoff-missing-component-shape).

Test fixture — meta-skill self-mode with the three-phase shape, the phase-N.md handoff-write prose, and the dryrun-label labeling section all present, but missing the cutoff prose at Phase 1 close and Phase 2 close. HANDOFF_EMISSION must report FAIL and the failure messages must cite state/inline-phase-transition (the handoff write IS referenced and the dryrun-label prose IS present, but the post-write inline transition is the failure mode).
