Conciseness

Meta-framework scaffolding ("Intent signature", "Control-flow features", "Scenes", the "SSL primitive" table) pads the body and duplicates content — "When to use" restates "Intent signature" and the Actions table restates the Scenes flow — so it is mostly efficient but could be tightened, not merely minor trimming.

Actionability

Some concrete guidance exists (Serena tool names find_file, search_for_pattern, get_symbols_overview, find_symbol; "run the smallest reproduction command first"), but most directives are abstract ("Isolate root cause and reject unsupported hypotheses") with no executable commands or examples inlined — the checklists and templates are all deferred to resources/ files not present in the bundle.

Workflow Clarity

The Entry → PREPARE/ACQUIRE/REASON/ACT/VERIFY/FINALIZE sequence is clear, with explicit feedback loops ("If the first fix fails verification, return to root-cause analysis"), failure/recovery paths, exit criteria, and guardrails; it falls short of a 5 because verification steps are named scenes rather than explicit commands or checkpoints.

Progressive Disclosure

The body is an overview with one-level-deep references that carry purpose labels ("Checklist (pre-submit self-verification)", "Error recovery"), but the reference list mixes ../_shared/ and resources/ paths, repeats references already cited in Dependencies, and no bundle files exist to verify the targets, leaving minor organization gaps.

Specificity

"Diagnose a reproducible failure, fix its cause, and verify the regression" lists three concrete actions covering the debug workflow, matching the several-specific-actions-with-minor-gaps anchor; it stops short of comprehensive coverage (e.g., root-cause documentation, regression-test authoring) needed for a 5.

Completeness

It explicitly answers both what ("Diagnose a reproducible failure, fix its cause, and verify the regression") and when ("Use for crashes, incorrect behavior, and failing tests") with concrete trigger phrases, mirroring the anchor-5 example structure; it is not a 4 because the when-clause is already explicit and specific.

Trigger Term Quality

"Use for crashes, incorrect behavior, and failing tests" provides natural phrases users would say, but omits common variations such as "bug", "error", "exception", or "traceback", so it fits good-coverage-with-a-few-missing-terms rather than comprehensive synonym coverage.

Distinctiveness Conflict Risk

The debugging niche ("reproducible failure", "verify the regression") is clearly distinguishable from feature-building or review skills, but "incorrect behavior" and "failing tests" leave minor overlap risk with test-writing and QA skills, fitting the mostly-distinct anchor rather than the minimal-conflict anchor.
