Conciseness

The body is dense and assumes Claude's competence — no space is spent explaining peer review, PDFs, or hashing concepts, and sections like Venue Selection and Artifact Intake are pure operational guidance. It falls short of 5 because critical rules (digest recomputation, PDF intake gating, no cross-reviewer exposure) are stated twice, once in Workflow steps and again nearly verbatim in Hard Constraints, which could be tightened to single pointers.

Actionability

Guidance is highly concrete for an instruction-only skill: exact paths ('paper/reviews/<venue>-review-r<N>/'), a closed reroute vocabulary with eight literal values, a venue normalization table, manifest fields, and a real script ('scripts/prepare_pdf_review.py', verified to exist). It is not a 5 because the PDF step never gives the script's actual invocation (arguments, output flags), forcing the reader to open the script to run it — a minor but real executable gap.

Workflow Clarity

The eight-step Workflow is an unambiguous sequence with explicit validation checkpoints and feedback loops: 'Stop before dispatch when its status is failed', 'Retry a failed reviewer at most once under the protocol; never silently reduce the ensemble size', digest recomputation before MetaReview with round invalidation on mismatch, and dispatch gating on 'pass' or 'pass_with_warnings'. This matches the 5 anchor's clear sequence, explicit validation, and error-recovery loops; nothing is missing.

Progressive Disclosure

The SKILL.md body is a genuine overview with a 'Required References' section that clearly signals one-level-deep files, all of which exist in the bundle (ensemble-protocol.md, review-contract.md, meta-review-contract.md, reroute-guide.md, pdf-intake-contract.md, and six venue templates under references/venues/). The venues/ subdirectory is a flat grouping, not a reference chain, and detailed contracts are appropriately split out rather than inlined — matching the 5 anchor's well-signaled, easy navigation.

Specificity

The description lists several concrete actions — 'Orchestrates three isolated reviewer subagents in parallel, then a separate MetaReview subagent that verifies evidence, reports agreement and score dispersion, and emits advisory reroutes' — all in third person. It falls just short of the 5 anchor because the actions are orchestration-level and never name the concrete output artifact (e.g., an ensemble review bundle), leaving a minor coverage gap.

Completeness

It explicitly answers both questions: 'Use when a completed research manuscript needs a robust internal, venue-calibrated mock peer review' (when) plus the subagent orchestration and MetaReview duties (what), and adds scope boundaries ('Never revises research artifacts, executes experiments, or updates pipeline state'). It is not a 5 because the 'when' clause is a single trigger phrasing without the concrete trigger variations and synonyms the 5 anchor requires.

Trigger Term Quality

Natural trigger phrases like 'mock peer review', 'research manuscript', 'reviewer', and 'venue' are present and would be said by a real user. However, the most common user phrasing 'paper' / 'paper draft' and the venue names (ICLR, NeurIPS) that the body supports are absent, matching the 4 anchor ('good keyword coverage; a few natural terms missing') rather than the 5 anchor's comprehensive synonym coverage.

Distinctiveness Conflict Risk

It carves a clear niche — ensemble mock peer review of a manuscript with advisory reroutes — and the 'Never revises research artifacts, executes experiments, or updates pipeline state' clause actively separates it from overlapping paper-pipeline skills. Trigger terms ('mock peer review', 'manuscript', 'MetaReview') are distinct, so conflict risk is minimal.
