What problem does it solve? This Skill provides a controlled test fixture that exercises lint rules for nested references and reference table-of-contents validation, letting tooling authors verify that linters correctly detect violations in skill reference files. ## Core Features & Use Cases - Nested Reference Fixture: Contains a reference/long.md file that links to reference/deep.md, deliberately triggering nested-reference violations. - Reference TOC Violation: Ships a long reference file with no Contents block and past the line limit to test reference-toc checks. - Dangling Link Cases: Includes dangling {{skill: kapture}} and {{agent: ghost}} references plus escaped variants that must not fire, validating linter precision. - Use Case: A developer maintaining the aos lint tooling runs the selftest suite, and this fixture confirms the linter flags nested references, missing TOCs, and dangling cross-skill links while ignoring escaped placeholders. ## Quick Start Run the lint selftest suite against this fixture to verify nested-reference and reference-toc violations are detected correctly.
