Conciseness

The body is lean and directive throughout — the implementation checklist lists domain-specific failure modes ("impossible control-flow path merges", "dynamic properties treated as static names") that Claude would not know, and there is no padding or explanation of known concepts. Not score 4 because no over-explanatory passages remain to trim; every line instructs.

Actionability

Mostly executable guidance: the truffler command is fully specified ("bunx @rayhanadev/truffler \"<helper-name>\" packages --kind function,method,interface,type,constant --limit 20"), "nr changeset" is concrete, and the PR copy template gives an exact structure. Not score 5 because "rde-eval" and "run-parity" are named but never given an invocation, and "Run focused tests, package typecheck, and required lint and format checks" states what to run without the commands. Not score 3 because the concrete commands and template cover the common cases.

Workflow Clarity

Clear sequence (review implementation → run validation → prepare artifacts → handle findings → report) with explicit validation steps and feedback loops: "Fix each implementation bug with a focused regression test", "Add every confirmed false positive to rule tests and the fuzz corpus", "Do not claim parity unless both Vercel Sandbox runs complete", and conditional handling ("Omit the eval table when parity did not run. State the reason instead."). This matches the anchor with checklists and error-recovery handling; nothing is missing for a lower score.

Progressive Disclosure

No bundle files exist and the body is well-organized into six clear sections with no nested references, so navigation is easy. Not score 5 because the ~25-line PR copy template is inlined in the body where a one-level-deep reference file (e.g. a pr-template.md) would keep SKILL.md a pure overview; the skill is also slightly above the ~50-line threshold where sections alone suffice. Not score 3 because the structure is otherwise appropriate and nothing is buried.

Specificity

The description enumerates seven concrete actions — "review detector correctness, inspect open-source hits, run pull request parity, add regression coverage, prepare a changeset, write pull request copy, or address review findings" — giving comprehensive coverage of the skill's scope, matching the anchor for multiple specific concrete actions. Not score 4 because there are no minor coverage gaps; the action list spans the full validation workflow.

Completeness

The 'what' is explicit ("Validate an implemented React Doctor rule before merge") and the 'when' is explicit with concrete trigger phrases ("Use after focused tests pass to review detector correctness... or address review findings"), matching the anchor that requires both clearly answered. Not score 4 because the 'when' clause is fully explicit and enumerates specific triggering situations rather than being merely adequate.

Trigger Term Quality

Good natural keyword coverage for the domain — "validate", "before merge", "regression coverage", "changeset", "pull request copy", "review findings" are phrases a developer would actually say. Not score 5 because common synonyms and variations are missing (e.g. "regression tests", "PR", "parity check"), and terms like "open-source hits" are jargon-shaped rather than user-shaped.

Distinctiveness Conflict Risk

A clear niche — validating an implemented React Doctor rule — with distinct triggers ("pull request parity", "changeset", "detector correctness") that no generic review or testing skill would claim. Minimal conflict risk with other skills. Not score 4 because the domain and trigger terms are highly specific, leaving no meaningful overlap with closely related skills.
