The body is lean and assumes Claude's competence — it never explains basic concepts (what a report/handoff is) and every section (brief fields, C1–C7 table, fail conditions, output contract) is load-bearing procedural guidance with no padding.

Gives concrete, copy-paste-ready instruction: explicit six-cell knowledge model, a C1–C7 checklist table with a 'Catches' column, enumerated Phase 3 fail conditions, and a precise output contract — fully actionable for an instruction-only skill.

Clear prepare → review → revise sequence with explicit validation checkpoints (mark each check pass/revised/residual-risk) and feedback loops (Phase 2 → revise → re-check; Phase 3 loop until pass), matching the score-3 anchor for sequenced workflows with validation and error-recovery loops.

No bundle files are present, so the skill is self-contained; it is well-organized into clearly signaled sections (Phase 1/2/3, Stop/output contract, Boundaries & friction) with no nested references, which satisfies progressive disclosure for a reference-free skill.

Lists multiple specific concrete actions: 'Run a prepare → review → revise pass', 'Builds a short communications brief', 'reviews the draft against it and against named agent-writing failure modes ... then revises or flags residual risk', matching the score-3 anchor for multiple specific concrete actions.

Clearly answers 'what' (prepare→review→revise pass with named failure modes) but the 'when' is only a soft condition ('before it is finalized') with no explicit 'Use when...' trigger guidance inside the description; per the judging guideline this caps completeness at 2.

Covers natural domain terms users would say — 'report, status update, strategy doc, review finding, handoff, recommendation' — giving good, varied coverage of likely user phrasings rather than generic jargon.

Occupies a clear niche — agent-written comms review against named failure modes such as 'buried recommendation' and 'leaked process history' — with distinct triggers unlikely to overlap with other skills.
