Conciseness

The core is dense, executable bash and status tables, but several sections add non-essential tokens: the 'Execution Contract (MANDATORY)' preamble, the host-adapter note, 'The Bottom Line' section repeating the intro, and the multi-LLM rationale prose ('A Claude-only review pipeline misses what external models catch...'). This matches 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than 4, where such padding would be only minor.

Actionability

Concrete, mostly executable bash for loading the intent contract, stub detection, provider dispatch, and PR posting, plus markdown output templates for each stage. Falls short of anchor 5 on small gaps: ${COMBINED_REPORT} is used but never defined in the posting script, and the 'Git not available -> use file listing' fallback gives no command.

Workflow Clarity

Clear staged sequence with an explicit Stage 1 gate table (PASS/FAIL -> proceed, ask user, or stop), per-criterion and per-boundary status marking, and an error-handling table covering five failure modes. Not 5: external reviews are spawned with '&' but no wait/collect mechanism is shown, and the stub-detection results are reported without a required follow-up action per issue.

Progressive Disclosure

The body has good section headers (two stages, numbered steps, gate/error tables), but it is a fully monolithic ~330-line file with no bundle at all: content that should be in separate files is inlined (the ~55-line stub-detection script, the PR-posting section), and the referenced 'skills/blocks/codex-host-adapter.md' does not exist in this bundle. This matches anchor 3 — structure present but content that should be separate is inline; not 2 because headers and navigation are clear, not 4 because there are no well-signaled reference files at all.

Specificity

The description names the domain ("a PR or feature") and two concrete review activities ("specification and code-quality review"), but never states what the skill actually does (e.g., runs a two-stage review pipeline). This matches anchor 3 — domain plus 1-2 concrete actions without comprehensive coverage — rather than 4, which requires several specific listed actions.

Completeness

The 'when' is explicit and specific ("Use when a PR or feature needs both specification and code-quality review"), but the 'what' is absent as a standalone statement — only weakly implied by the activities inside the trigger clause. Not score 2 because the when-clause is far more specific than the vague 'Use when working with documents' example; not 4-5 because no clear 'what' is stated.

Trigger Term Quality

"PR", "feature", "specification", and "code-quality review" are natural terms a user would say when needing this skill. It falls short of anchor 5 because common variations are missing, such as "pull request", "code review", "spec compliance", or "merge readiness".

Distinctiveness Conflict Risk

The requirement for "both specification and code-quality review" carves a distinct niche versus single-purpose code-review skills, but there is minor overlap risk with closely related generic PR-review skills that also mention specification and quality. Not 5, since the description lacks distinctive trigger phrases that fully separate it from those skills.
