Conciseness

The debugging-specific lists ('When invoked', 'Debugging process', 'For each issue') are lean, but the templated 'Use this skill when / Do not use this skill when' boilerplate ('Working on debugger tasks or workflows') and generic Instructions bullets ('Apply relevant best practices and validate outcomes') are padding, fitting 'Mostly efficient but includes some unnecessary explanation'; not 2 because the core content is not severely verbose.

Actionability

Guidance is high-level hints only ('Capture error message and stack trace', 'Add strategic debug logging') with no code, commands, or specific tools, matching 'Minimal concrete guidance; high-level hints but missing the specific steps to execute'; not 1 because it gives a structured, ordered process rather than purely abstract description.

Workflow Clarity

The numbered 'When invoked' sequence (capture -> identify reproduction -> isolate -> implement minimal fix -> verify) is clearly ordered with a 'Verify solution works' checkpoint, matching 'Clear sequence with most checkpoints present; minor validation gaps'; not 5 because there is no explicit error-recovery feedback loop (what to do when verification fails).

Progressive Disclosure

The body is sectioned into headers, but its only external reference points to 'resources/implementation-playbook.md', which does not exist (no references/scripts/assets dirs), so the pointer is broken, fitting 'references present but not clearly signaled'; not 4 because the dead reference is a real navigation defect, and not 2 because the section structure itself is reasonable.

Specificity

It names the domain ('Debugging specialist') and the problem types ('errors, test failures, and unexpected behavior') but lists no concrete actions a user would invoke, matching 'Names the domain but actions are minimal or generic'; not a 3 because no executable actions (capture, isolate, fix) are stated.

Completeness

Both what ('Debugging specialist for errors, test failures, and unexpected behavior') and when ('Use proactively when encountering any issues') are explicit, but the 'when' is generic rather than concrete trigger phrases, matching 'Has both what and when; when could be more explicit or specific'; not 5 because no concrete trigger phrases.

Trigger Term Quality

Natural terms like 'errors', 'test failures', 'unexpected behavior', and 'issues' are present, but common debugging synonyms users actually say ('bug', 'crash', 'exception', 'stack trace', 'not working') are missing, fitting 'Some relevant keywords but missing common variations or synonyms'; not a 4 due to those notable gaps.

Distinctiveness Conflict Risk

'Debugging specialist' is a clearly distinct niche with mostly distinct triggers, but the phrase 'when encountering any issues' broadens it and creates minor overlap risk with other support skills, matching 'Mostly distinct; minor overlap risk'; not 3 because debugging is a well-defined, recognizable niche.
