Conciseness

The body is lean and directive — every step carries only instructions Claude doesn't already know (e.g. "Record the JSON location, required companions, ID references, clock domain, parameter representation, effect ordering, and asset dependencies"), with no background concepts or padding. It matches the level-5 anchor: every token earns its place.

Actionability

Step 2 provides concrete, executable commands ("python3 -B \"{camtasia_skill_root}/scripts/project.py\" diff \"<before>\" \"<after>\""), and the instructional guidance is specific throughout. However, Step 3's audit commands ("using the commands in the native verification reference") and Step 4's "helper contract for validation and writes" are deferred to external references without even one inline example, leaving minor gaps.

Workflow Clarity

The four steps are explicitly sequenced ("Process steps in order. Do not skip ahead", "Proceed immediately to Step N") with validation checkpoints (schema audit in Step 3, native open/save/reopen verification in Step 4) and error-recovery guidance ("Resolve discrepancies through native evidence", "Record any editor repairs"). It matches the level-5 anchor including the explicit gate "Do not close the investigation with its required native verification outstanding."

Progressive Disclosure

The SKILL.md is an overview that defers detail to fully pathed, one-level-deep references (features.md, sources.md, native-verification.md, scripts/project.py). It falls short of level 5 because those references resolve through a rebased external skill root ("ACR rebases that package reference to the installed skill") and none of the referenced files ship in this bundle, adding navigation indirection that cannot be verified here.

Specificity

The description lists multiple concrete actions — "Research a Camtasia feature's serialized JSON, compare before/after projects, or extend support for transitions, behaviors, mattes, cursor effects, templates, markers, quizzes" — with comprehensive coverage of the domain's feature areas. It exceeds the level-4 anchor because there are no minor gaps in the action coverage within its niche.

Completeness

The "what" is clear (research serialized JSON, compare projects, extend feature support), but there is no "Use when..." clause or equivalent explicit trigger guidance — the "when" is only weakly implied by "other unfamiliar project structures". Per the judging guideline, a missing explicit trigger clause caps completeness at 3.

Trigger Term Quality

It includes natural terms Camtasia users would say ("transitions", "behaviors", "mattes", "cursor effects", "markers", "quizzes", "before/after projects") but omits common variations like file extensions (.tscproj/.cmproj) or the phrase "Camtasia project file". This matches the level-4 anchor (good coverage, a few natural terms missing) rather than level 3, since the everyday feature vocabulary is present.

Distinctiveness Conflict Risk

"Camtasia" names a clear niche and the enumerated feature triggers (mattes, cursor effects, quizzes, markers) are specific to that application, giving minimal overlap risk with other skills. It is not level 4 because no closely related skill would plausibly claim these triggers.
