Conciseness

The body is noticeably padded: the fresh-reviewer rule is stated at least four times (opening blockquotes, "CRITICAL: Use a fresh reviewer agent every run", Key Rules "Fresh thread EVERY run", and the Thread independence section), and large sections ("Review Tracing", "Submission Artifact Emission", reviewer-routing blockquotes) repeat internal assurance policy in dense prose. This matches anchor 2 ("several unnecessary explanations or padded sections") better than anchor 3, since a zero-context reader cannot resolve much of this material and the redundancy is systematic rather than occasional.

Actionability

There is real concrete guidance — the embedded audit protocol with seven named failure modes, the per-claim output format, report templates, and a verdict decision table. But the central action (spawning the reviewer) is given only as a pseudo-YAML `spawn_agent:` block rather than an executable command, key values are placeholders ("[list .tex file paths]"), and the routing/tracing mechanics are delegated to files that do not exist in the bundle (`reviewer_route.py`, `save_trace.sh`, `shared-references/*.md`), leaving gaps beyond anchor 4's "minor gaps".

Workflow Clarity

Steps 1–4 (collect files → fresh reviewer audit → write report → print summary) are clearly sequenced, and checkpoints are mostly present: a status taxonomy (exact_match … unsupported_claim), a verdict decision table covering error paths (BLOCKED, ERROR), and explicit path/hash conventions. Not a 5 because validation of the skill's own outputs is delegated to an external `verify_paper_audits.sh` that isn't shipped, and the routing blockquotes at the top obscure the entry point.

Progressive Disclosure

The bundle contains no reference or script files, yet the body points to at least five external docs (`../shared-references/reviewer-backends.md`, `review-tracing.md`, `integration-contract.md`, `assurance-contract.md`, `reviewer-independence.md`) and several scripts/skills — none resolvable. Meanwhile ~100 lines of template content (the full spawn_agent message and the JSON artifact schema) is inlined in SKILL.md where it belongs in separate reference files. This matches anchor 2 ("content that clearly belongs in separate files is inlined; or references are buried"); it is above anchor 3's example only in that references are at least explicitly named.

Specificity

The description names a concrete action — "verification that every number, comparison, and scope claim in the paper matches raw result files" — with enumerated claim types and the mechanism ("Uses a fresh Codex reviewer with no prior context"). It falls just below anchor 5 because "base output is same-family provisional" is internal pipeline jargon rather than a user-facing capability, and there are minor coverage gaps (no mention of the report/artifact outputs).

Completeness

Explicitly answers both questions: what ("Zero-context verification that every number, comparison, and scope claim in the paper matches raw result files") and when ("Use when user says ... or before submission"), matching the anchor-5 pattern of concrete trigger phrases. Voice is third person ("Uses"), so no voice penalty applies.

Trigger Term Quality

Includes natural trigger phrases "check paper claims", "verify numbers", "before submission", plus Chinese variants "审查论文数据" and "论文数字核对". Not a 5: common synonyms like "audit the paper", "fact-check", or file extensions (.tex, results files) are missing, and "verify numbers" alone is somewhat generic.

Distinctiveness Conflict Risk

Triggers are paper-specific and unlikely to fire for unrelated skills, and the paper-framing distinguishes it from experiment/data audits. Not a 5 because "verify numbers" could overlap with closely related audit skills (the body itself lists siblings like /experiment-audit and /result-to-claim), so minor overlap risk remains.
