Conciseness

Mostly dense, actionable instruction Claude could not infer, but the model-diversity rationale is repeated nearly verbatim three times ("Model diversity is the strongest/main lever" in Mindset, Step 5, and two Anti-Patterns), and the Mindset bullet about Editorial/Decision classification duplicates Step 10. Not 4 because the redundancy goes beyond minor trimmable instances; not 2 because there is no padding explaining concepts Claude already knows.

Actionability

Fully executable guidance throughout: exact commands ("sh <path>/validate-context-frontmatter.sh .context/plans/<plan-file>.md", "find -L <skills dir> -name validate-context-frontmatter.sh", "bash <this skill's directory>/scripts/validate-plan-review-config.sh <path>"), a reviewer/subagent-type/model table, and ready Agent-call prompt templates with a paste slot. As an instruction-only skill the guidance is copy-paste ready and covers the common cases.

Workflow Clarity

An 11-step sequence with explicit validation checkpoints (frontmatter validation script, schema validation of the report, a 6-item Verification checklist) and error-recovery feedback loops ("Re-spawn that reviewer individually... if a reviewer fails twice, fall back to the other two"). Matches the level-5 anchor: clear sequence, explicit validation, feedback loops, and a checklist.

Progressive Disclosure

The body is an overview/workflow that delegates detail to one-level-deep, well-signaled references (model-routing.md, structural-inference.md, reviewer-prompts.md, saving-the-report.md) with a References table giving 'When to Use' per entry, plus templates/schemas/scripts that all exist in the bundle. References do not chain into further instructional docs. This matches the clear-overview, well-split level-5 anchor.

Specificity

"Runs 3 independent subagent reviewers (Technical, Strategic, Risk) on the same plan brief and consolidates their findings" and "Reads reviewer models from .claude/plan-review.json" list several concrete actions in third-person voice. Not 5 because coverage has minor gaps (structural validation and report generation are part of the skill but unmentioned); clearly above 3, which expects only 1-2 concrete actions.

Completeness

Explicitly answers both: what ("Runs 3 independent subagent reviewers... consolidates their findings") and when ("Use when asked to review, audit or quality-check a plan in .context/plans/") with concrete trigger phrases, matching the level-5 anchor. A level-4 score would require the 'when' to be less explicit, which it is not.

Trigger Term Quality

"review, audit or quality-check a plan" plus the concrete location trigger ".context/plans/" give good natural keyword coverage. Not 5 because a few natural variants users might say (e.g. "validate a plan", "get a second opinion on a plan", "critique") are missing; above 3 since multiple relevant natural phrases are present.

Distinctiveness Conflict Risk

A clear niche (multi-reviewer audits of ".context/plans/" files) with distinct triggers and an explicit exclusion clause ("Not for plans outside .context/plans/, one-off notes, or external documents") minimizing conflict risk. Not 4 or below, since the negative boundary removes overlap with adjacent review/reflection skills.
