Skilltest Harness

Discover, validate, and test skills against the Open Agent Skills standard.

Discovery
- Search .claude/skills/ recursively.
- Find SKILL.md files.
Validation
- Structure: Skill folder must contain SKILL.md.
- Metadata: SKILL.md frontmatter must be valid YAML.
- Paths: Scripts and references must exist.
- Symlinks: Validate targets.
Execution
- Run test cases from tests/cases/*.cases.json.
- Report successes and failures.

Use the bundled validator:

node .claude/skills/skilltest/scripts/validate-skills.mjs

Use the test runner:

node .claude/skills/skilltest/scripts/skilltest.mjs

Generated report path:

reports/skills/skilltest-report.json

Input: "Why isn't my skill showing up?"

Action: Run validator.

Output:

[FAIL] myskill/SKILL.md: Invalid YAML frontmatter.

"The frontmatter in myskill/SKILL.md is invalid. Fix the YAML syntax."

Skill sync: compatible with React 19.2.6 / Vite 8.0.10 / Tailwind 4.2.4 baseline as of 2026-05-20.
