Conciseness

The body is lean and operational — commands, a justified version pin, tight parity/difference lists — but the cold-context rationale is stated twice ('codex exec is a separate cold process...' and 'the value of a cold Codex pass is surfacing what the current session would rationalize away') and the version/upgrade detail is time-sensitive information outside any deprecated/old-patterns section, leaving minor trimmable excess short of anchor 5.

Actionability

Fully executable, copy-paste-ready commands cover the common cases: 'bash .agents/skills/local-review-codex/run.sh' with a custom-base variant, 'npm install --global @openai/codex@0.159.3', 'codex login', and 'git fetch', plus concrete fallback behavior (origin/main) and explicit relay instructions (print output verbatim).

Workflow Clarity

A clear Prerequisites → Run → Relay sequence with explicit checkpoints: the version check up front, the bash-vs-sh invocation caveat, the origin/main fallback, and the closing decision loop ('decide with the user whether to address findings before pushing'). The skill is read-only (no destructive/batch cap applies) and single-purpose with well-organized sections, satisfying the simple-skill exception for anchor 5.

Progressive Disclosure

No bundle files exist, and the body is under 50 lines with well-signaled sections (Correspondence with CI, Differences from CI, Prerequisites, Run, Relaying the result), delegating mechanics to run.sh instead of inlining them — matching the under-50-lines exception where well-organized sections alone warrant anchor 5.

Specificity

The description gives a concrete action with precise scope and timing — 'Run the CI Codex PR review locally against this branch's unpushed work (committed + uncommitted) before pushing' — but it is essentially one action with qualifiers rather than the multiple distinct actions of anchor 5.

Completeness

Both what ('Run the CI Codex PR review locally... (committed + uncommitted)') and when ('before pushing') are answered explicitly, but the when is embedded in the action sentence rather than a distinct 'Use when...' trigger clause, matching anchor 4's 'when could be more explicit' rather than anchor 5.

Trigger Term Quality

Natural keywords are present ('Codex', 'PR review', 'locally', 'unpushed', 'before pushing', 'GitHub action') and would be said by a user needing this skill, but a few natural variants like 'pre-push' or 'review my branch before push' are missing, so it falls short of anchor 5's synonym-level coverage.

Distinctiveness Conflict Risk

The description carves a clear niche — the local counterpart of one specific CI job ('Same policy, model and reasoning effort as the codex-pr-review GitHub action') — with distinct triggers ('CI Codex PR review', 'before pushing') and minimal conflict risk with generic review skills.
