Invalid sidecar

Skill jacob-balslev/skill-graph/audits/gate-conformance/fixtures/invalid/invalid-sidecar

Negative fixture for the gate-conformance suite: the SKILL.md frontmatter is fully valid, but the sibling audit-state.json sidecar is missing the required `owner` field. Activate only inside test-gate-conformance.js to prove the structural lint gate validates the sidecar against schemas/skill-audit-state.schema.json. Do NOT use as a production skill.From its SKILL.md

Invalid Sidecar (negative fixture)

This fixture is intentionally invalid at the SIDECAR layer: the SKILL.md frontmatter is valid, but audit-state.json omits the required owner field. The structural lint gate validates the sidecar against its schema and MUST reject this.

Concept of the skill

What it is: A deliberately broken capability skill used only by the conformance runner. Mental model: Keep the frontmatter valid but break the sibling audit-state.json so the sidecar-schema branch of the structural gate is the thing under test. Why it exists: To guard the sidecar-validation path — a regression that stopped validating audit-state.json against its schema would otherwise pass the suite. What it is NOT: It is not a production skill and never routes outside the test runner. Adjacent concepts: the other negative fixtures under this directory; the audit-state.json sidecar (ADR-0019); the skill-audit-state schema. One-line analogy: It is a form with the body filled in but a required field on the attached cover sheet left blank. Common misconception: That sidecar validity is the Behavior Gate's concern — it is structural (the Integrity Gate validates the sidecar shape before any eval runs).

Coverage

Valid frontmatter, invalid sidecar (missing required owner) → structural lint failure.

Philosophy of the skill

One broken layer per fixture keeps the failing assertion unambiguous.

Verification

Exercised by the gate-conformance runner; expected to fail structural lint with a sidecar required-field error.

Do NOT Use When

  • Always. This is a test fixture, not a usable skill.
