Conciseness

The body is dense and assumes Claude's competence — no tutorials on what skills are, and every section (criteria table, naming rules, template, checklist) is operational. Minor trimming opportunities exist: the reserved-fragment rule appears in both Step 3 and the Step 6 checklist, and the ~40-line inline SKILL.md template could live in a reference file. It fits anchor 4's 'efficient; minor instances that could be trimmed' rather than anchor 5's 'every token earns its place'.

Actionability

Mostly executable guidance: a copy-pasteable bash snippet for searching auto-memory, concrete naming rules with good/bad examples, an explicit output file layout, a full SKILL.md template, and two worked example invocations. The key gap is Step 4's 'Spawn the skill-extractor agent' — the core generation step gives no agent prompt or spec, so it falls just short of anchor 5's 'fully executable; copy-paste ready'.

Workflow Clarity

Seven clearly sequenced steps with an explicit validation checkpoint (the Step 6 quality-gates checklist before finalizing) and a concrete report format. It matches anchor 4's 'clear sequence with most checkpoints present; minor validation gaps' — there is no explicit fix-and-recheck loop when a gate fails, and file creation is not destructive so the anchor-3 cap for unvalidated batch/destructive operations does not apply.

Progressive Disclosure

No bundle files exist and the single SKILL.md is well organized with clear section headers and no nested references. The ~190-line body inlines the full generated-SKILL.md template and example block, which could be split into a reference file for a leaner main file, so it fits anchor 4's 'good structure; minor organization gaps' rather than anchor 5 (which the under-50-line simple-skill exception would require).

Specificity

The description names the domain (skill extraction) and several concrete deliverables — 'a standalone reusable skill with SKILL.md, reference docs, and examples' — but omits other actions the skill performs (naming rules, quality gates), leaving minor coverage gaps. It lists several specific actions rather than only 1-2, so it sits above the anchor 3 example but below anchor 5's comprehensiveness.

Completeness

Both halves are explicit: the 'what' is 'Turn a proven pattern or debugging solution into a standalone reusable skill with SKILL.md, reference docs, and examples' and the 'when' is the concrete 'Use when the user runs /si:extract or asks to package a recurring solution from memory into a skill'. This matches anchor 5's clear, explicit what-and-when with concrete trigger phrases, exceeding anchor 4's 'when could be more specific'.

Trigger Term Quality

Triggers include the concrete command '/si:extract' and the natural request phrasing 'asks to package a recurring solution from memory into a skill', which maps well to what a user would actually say. Common synonyms like 'save this as a skill', 'create a skill', or 'turn this fix into a skill' are absent, keeping it just below anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The niche — extracting a reusable skill from a proven pattern or debugging solution stored in memory — is distinct, and the '/si:extract' command trigger plus the memory-packaging phrasing minimize overlap with generic skill-creation or documentation skills. It matches anchor 5's 'clear niche with distinct triggers; minimal conflict risk'; it is not merely 'mostly distinct' as in anchor 4.
