Conciseness

The body never explains concepts Claude already knows (no 'what is Camtasia', no JSON tutorial) and every sentence is operational, e.g. "Repeat `--preserve-track` for each unchanged lane; omit it when no whole lane can remain unchanged." Version-specific details (Mac profiles) are delegated to references rather than inlined, matching the lean score-5 anchor.

Actionability

Every core step ships a copy-paste-ready command with exact flags and expected output fields ("validate ... --media-root", "apply ... --expected-sha256 ... --preserve-track", "stdout reports `changed`, `sha256`, `backup`, and `validation`"). Edge paths (font handoff, source bundles) route to verified sections of helper.md whose anchors exist, so there are no executable gaps.

Workflow Clarity

Five strictly ordered steps with explicit validation checkpoints and feedback loops ("Fix errors; investigate warnings relevant to the change"), a hash baseline guarding the destructive apply ("--expected-sha256"), backups, and a final verify step that re-inspects and runs a native save/reopen roundtrip. This matches the score-5 anchor including error-recovery guidance, and the destructive-operation cap does not apply since validation is pervasive.

Progressive Disclosure

The body is a pure overview routing to one-level-deep, conditionally-signaled references ("For captions or source transcription, also read [captions]"), and all cited files exist in references/ with working anchors (helper.md#source-bundle-staging, helper.md#font-resource-handoff verified against actual headings). Bulk detail (40 reference files, 26 scripts) stays out of SKILL.md, matching the score-5 anchor.

Specificity

The description lists five concrete actions ("Inspect, create, edit, package, or validate") plus file extensions and a long roster of specific operations ("timeline cuts, source relinking, portable bundles, ... project JSON repairs"), giving comprehensive rather than minor-gap coverage. It clearly exceeds the score-4 anchor, which allows for coverage gaps.

Completeness

Both questions are answered explicitly: the 'what' is "Inspect, create, edit, package, or validate Camtasia .cmproj and .tscproj projects" and the 'when' is the concrete "Use for" clause enumerating trigger tasks. Not 4, because the 'when' is explicit and specific rather than improvable.

Trigger Term Quality

Strong natural-phrasings coverage ("timeline cuts", "captions", "zooms", "quizzes", ".cmproj", ".tscproj"), but common user phrasings like "screen recording", "video editing", and Camtasia's own "export/produce/share" vocabulary are absent. This fits the score-4 anchor ("good keyword coverage; a few natural terms missing") better than the score-5 anchor's comprehensive synonym coverage.

Distinctiveness Conflict Risk

"Camtasia .cmproj and .tscproj projects" carves out a clear niche with product-specific extensions and feature names, so overlap with any other skill is minimal. Clearly matches the score-5 anchor rather than the score-4 'minor overlap risk' anchor.
