Agent Toolkit Skill Guide Plugin
Reusable agent skill for designing, organizing, authoring, validating, and adding deterministic scripts to agent skills.
Skill
skill-guide
Use when designing, organizing, authoring, or validating agent skills. It covers required structure and frontmatter, progressive disclosure, deterministic workflows, executable skill scripts, runtime selection, script tests, and a practical validation checklist.
create-skill
Use when scaffolding a new skill inside an existing plugin. The bundled
preview-first Node CLI creates the initial SKILL.md and README, prints an
approval hash, and refuses to overwrite an existing skill. Script tests live in
tests/skill-guide/skills/create-skill/scripts/; Waza and Vally coverage remain
under that skill's repository-level test folder.
Evaluation
The skill is evaluated through the repository-level Vally suite:
VALLY_EVAL_SPEC=tests/skill-guide/skills/skill-guide/vally/eval.yaml mise run vally-eval-copilot-local
The evaluation covers skill authoring guidance, validation/safety checks, and the create-skill workflow. Skill-only plugins use Vally evaluations rather than .NET unit or integration test projects.
More information
The skills are documented separately:
