Conciseness

The body is lean and imperative throughout: no concept explanations, no padding, and every rule is directive ('Preserve the principle, not the incident chronology', 'Each area inbox is limited to ten topics and 8 KB'). Re-checked against anchor 4: there is no over-explanation of things Claude already knows that could be trimmed.

Actionability

For an instruction-only skill the guidance is fully concrete: a classification table mapping each feedback kind to an exact destination, an exact path pattern (`.github/learnings/<area>.md`), a copy-paste-ready entry template, and hard numeric limits (ten topics, 8 KB, 90 days). Per the scoring notes, absence of code is not penalized when guidance is this actionable.

Workflow Clarity

Six numbered steps run identify → search → classify → generalize → record → validate, with an explicit validation step ('Check links and remove superseded or contradictory guidance') and a compaction review checklist with concrete triggers (either limit reached, 90-day staleness). The destructive compaction operations are covered by validation, so no cap at 3 applies.

Progressive Disclosure

The bundle is a single self-contained SKILL.md with no reference files and no content that warrants splitting at ~4 KB; sections (Workflow, inbox format, reading learnings, compaction/GC) are clearly headed and easy to navigate, and the `.github/learnings/` paths it names are the artifacts it operates on, not bundle references.

Specificity

Names the domain ('explicit corrective feedback', 'skills or instructions') with two concrete actions ('Classify and record'), but coverage is not comprehensive — the body's search-before-write, promotion, and compaction behaviors are absent from the description. Not a 4 because only two specific actions are listed; not a 2 because the actions are concrete rather than generic.

Completeness

A clear 'what' is present ('Classify and record explicit corrective feedback without turning skills or instructions into append-only knowledge dumps'), but there is no 'Use when...' clause or any trigger guidance, which caps completeness at 3 per the judging guidelines. Not a 2 because the 'what' is clear, not vague.

Trigger Term Quality

'feedback' and 'corrective feedback' are relevant keywords, but the natural phrases users actually say for this skill — 'learn from this', 'remember this', 'don't do that again' — are missing. Not a 4 because keyword coverage lacks these common variations rather than just a few.

Distinctiveness Conflict Risk

The corrective-feedback classification niche is mostly distinct from generic documentation or file skills, but the absence of trigger phrases and the mention of broad 'skills or instructions' leaves minor overlap risk with memory-keeping and skill-authoring skills. Not a 5 because it has no distinct trigger phrases to disambiguate it from those closely related skills.
