Conciseness

The body is dense operational instruction rather than concept explanation, but at ~240 lines it could clearly be tightened: the extension-hook procedure is duplicated nearly verbatim in Pre- and Post-Execution Checks (~60 lines), quoting-escape advice for "I'm Groot" is oddly placed, and output formats are over-specified down to table layouts. It fits anchor 3 (mostly efficient but could be tightened) better than anchor 2, since nearly all prose is procedural rather than padding with things Claude already knows.

Actionability

Guidance is highly concrete and executable: the exact command ".specify/scripts/bash/check-prerequisites.sh --json --paths-only" with named JSON fields, exact output templates for hooks, exact bullet format "- Q: <question> → A: <final answer>", exact literal reply strings ("yes", "recommended", "suggested"), and exact failure handling. Not a 5 because there is no worked example of an actual question/table and a few details (e.g. the shell-escaping aside) are more confusing than actionable.

Workflow Clarity

Steps 1-8 are explicitly sequenced with a dedicated validation checklist after each write plus a final pass (step 6), error-recovery feedback loops (JSON parse failure aborts with recovery instructions; ambiguous answers trigger disambiguation without consuming the question quota), and early-termination rules. This matches the top anchor: clear sequence, explicit validation, feedback loops, and a checklist for a complex interactive process.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent), so everything — the ~60 lines of duplicated hook-checking procedure, the full 11-category taxonomy, and detailed formatting templates — is inlined in one 240-line SKILL.md. Section headers do provide internal structure, but content that clearly belongs in a one-level-deep reference file is inline, matching anchor 3 rather than 2 (structure exists) or 4 (nothing is split out).

Specificity

The description lists several concrete actions — "Identify underspecified areas", "asking up to 5 highly targeted clarification questions", "encoding answers back into the spec" — in third person. It is not a 5 because coverage is not comprehensive (the spec-update, taxonomy scan, and coverage-report behaviors are only implied by "encoding answers back"), and not a 3 because more than 1-2 distinct concrete actions are explicitly named.

Completeness

The "what" is clear (identify underspecified areas, ask up to 5 clarification questions, encode answers into the spec), but there is no "Use when..." clause or equivalent explicit trigger guidance — the "when" is only weakly implied by the spec context, which caps completeness at 3 per the judging guidelines.

Trigger Term Quality

Relevant keywords exist ("underspecified", "feature spec", "clarification questions") but common natural phrasings users would say — "ambiguous", "unclear requirements", "gaps in the spec", "spec review" — are missing, as are variations/synonyms. It sits above anchor 2 (which has only generic keywords) but below anchor 4 (good coverage with few missing terms).

Distinctiveness Conflict Risk

The feature-spec clarification framing is a distinct niche unlikely to fire for unrelated skills, but it does not mention the spec-kit context or distinguish itself from sibling skills in the same family (/speckit.specify, /speckit.plan), leaving minor overlap risk. Not a 5 because the trigger surface overlaps related spec-workflow skills; not a 3 because the action described is not something a sibling skill also claims to do.
