Validate skill files for structural compliance and behavioral correctness. Three modes: static (linter), spec (behavioral), audit (coverage report).
Passed 16 of 21 test cases with the skill, and 7 of 21 without it.

Tokens, turns and time describe resource use, not a dollar price.
One of 10 test cases the skill fixed. Same model, same prompt, with and without the skill.
A spec static assertion checks if an agent's frontmatter model tier is `sonnet`. The agent frontmatter specifies `model: inherit`. Should this assertion evaluate to PASS or PARTIAL?
| Checked | Without skill | With skill |
|---|---|---|
| Fails literal value assertions when frontmatter keys do not match exact expected values. | Missed | Passed |
| Rejects near-matches or inherited defaults for exact frontmatter assertions. | Missed | Passed |
The instructions your model reads when the skill loads.

Automation mode: Resolve modes.automation (project.local.yaml →
project.yaml → default collaborative). Every AskUserQuestion call and
every file write follows .claude/docs/automation-modes.md
(collaborative asks always · guided major-only · autonomous logs and proceeds;
automation_always_ask categories always prompt).
Validates skills (.claude/skills/*/SKILL.md) and agents (.claude/agents/*.md)
for structural compliance and behavioral correctness. No external dependencies —
runs entirely within the existing skill/hook/template architecture.
Four modes:
| Mode | Command | Purpose | Token Cost |
|---|---|---|---|
static | /skill-test static [name|all] | Structural linter — 7 compliance checks per skill (skills only) | Low (~1k/skill) |
spec | /skill-test spec [name] | Behavioral verifier — evaluates assertions in a skill's or agent's test spec | Medium (~5k each) |
category | /skill-test category [name|all] | Category rubric — checks a skill or agent against its category-specific metrics | Low (~2k each) |
audit | /skill-test audit | Coverage report — skills, agent specs, last test dates | Low (~3k total) |
Determine mode from the first argument:
static [name] → run 7 structural checks on one skillstatic all → run 7 structural checks on all skills (Glob .claude/skills/*/SKILL.md)spec [name] → read the skill or agent + its test spec, evaluate assertionscategory [name] → run category-specific rubric from CCGS Skill Testing Framework/quality-rubric.mdcategory all → run category rubric for every skill and every agent that has a category: in catalogaudit (or no argument) → read catalog, list all skills and agents, show coverageIf the argument is unrecognized, output usage and stop.
Resolve the name before spec or category. Look it up in
