Conciseness

The body is dense with operational specifics — scoring rubrics with numeric anchors, exact git commands, fill-in templates — and never explains concepts Claude already knows, fitting anchor 4 ('efficient; minor instances of over-explanation that could be trimmed'). It is not a 3 because there is no genuinely unnecessary explanation; the only trimmable fluff is the cryptic tagline 'Vela 3-layer pipeline × ADHD 4-frame reasoning — prompt-native, zero dependencies' and a few rationale sentences like 'zero uncertainty in a fast-moving session is a feature, not a reason to discard it'.

Actionability

Fully executable throughout: concrete commands ('git log --oneline -10', 'git diff --stat HEAD~3..HEAD'), a complete runnable Python script for token collection, exact output templates for DECISIONS.md/session-history/WORKLOG, fixed CSS tokens, and a fixed HTML class structure written via a bash heredoc — matching anchor 5 ('fully executable; copy-paste ready code or commands').

Workflow Clarity

The Layer 01 → 02 → 03 sequence is clear with branches per signal level and explicit user-visible checkpoints ('Show the user: Signal: HIGH / MEDIUM / LOW', 'resolve to this structure (show it to the user)'), plus a defined PreCompact merge flow — anchor 4 ('clear sequence with most checkpoints present; minor validation gaps'). Not a 5: there are no error-recovery steps for foreseeable failures (git commands failing outside a repo, missing ~/.claude/projects, malformed jsonl) and no verification after file appends.

Progressive Disclosure

There are no bundle files at all — everything (~380 lines) is inlined in SKILL.md. The fixed HTML structure spec (~70 lines), CSS tokens, and the token-collection script are only needed for HIGH-signal sessions yet always occupy context, matching anchor 3 ('content that should be separate is inline'). Section organization itself is good, ruling out anchor 2's 'minimal structure', but at this size with zero external references it cannot reach anchor 4.

Specificity

The description states a purpose — "understand what Claude contributed vs what you drove in a session" — but names no concrete actions the skill performs (no mention of session classification, frame scoring, or generating DECISIONS.md/session-history/WORKLOG/HTML reports), matching anchor 2 ('names the domain but actions are minimal or generic') rather than anchor 3's '1-2 concrete actions'. It also uses second person ('Use when you want to...'), which the judging guidelines penalize by reducing specificity by 1.

Completeness

Both what and when are present: an explicit trigger clause ('Use when you want to understand... Triggers on: ...') plus a purpose statement. The 'what' is a goal-level description rather than a concrete account of outputs, so it falls short of anchor 5's 'clearly and explicitly answers both what AND when with concrete trigger phrases' and lands on anchor 4.

Trigger Term Quality

Five explicit triggers are listed — "/collab-proof, session retrospective, ai contribution analysis, collaboration evidence, what did claude do" — several of which are natural user phrases; however, common variations like 'session summary' or 'what did we accomplish' are missing, so it fits anchor 4 ('good keyword coverage; a few natural terms missing') rather than anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The niche — session retrospection and AI-contribution evidence — is clearly distinct, with triggers like '/collab-proof' and 'what did claude do' unlikely to fire for any other skill, matching anchor 5 ('clear niche with distinct triggers; minimal conflict risk').
