Conciseness

The 8-line body is very lean and explains nothing Claude already knows, but "Process steps in order. Do not skip ahead." plus "Finish here." are redundant meta-statements for a single-step workflow that could be trimmed. This is anchor 4 (efficient with minor trimmable instances), not 5 (every token earning its place).

Actionability

"Run .codex/skills/acr__example__all-agents__review-change/scripts/check.sh" is a concrete command with an explicit output contract ("It emits {\"ok\":true} on stdout and exits non-zero on failure"), but the path does not match the bundle's actual scripts/check.sh location and no arguments or working directory are specified. Anchor 4 (mostly executable, minor gaps), not 5.

Workflow Clarity

The simple-skill exception applies: the single action (run the check script and read its result) is mostly unambiguous and the operation is non-destructive, so the validation cap does not apply. However, there is no instruction for what to do when the script exits non-zero, matching anchor 4 rather than 5.

Progressive Disclosure

The body is short with a clear section, and the referenced script exists in the bundle, but it is referenced via a non-bundle-relative path instead of scripts/check.sh, and the bundled references/REFERENCE.md is never mentioned in the body. Minor organization gaps place this at anchor 4, not 5.

Specificity

"Review a proposed code change and its evidence" names the code-review domain and one composite action, but does not list several concrete actions (no mention of inspecting diffs, running checks, or evaluating evidence types). It fits anchor 3 (domain plus 1-2 actions, not comprehensive), not 4 (several specific actions).

Completeness

Both parts are present: the what ("Review a proposed code change and its evidence") and an explicit when ("when asked to assess implementation quality"). The when-clause is somewhat circular and could be more concrete, matching anchor 4 rather than 5; the explicit when-clause means the missing-trigger cap of 3 does not apply.

Trigger Term Quality

Natural keywords like "review", "code change", and "assess implementation quality" are present, but common variations users would actually say ("diff", "PR", "pull request", "staged changes") are missing. This matches anchor 3 (relevant keywords, missing common variations), not 4 (good coverage with only a few missing).

Distinctiveness Conflict Risk

"Review a proposed code change" overlaps substantially with generic code-review skills, though "and its evidence" adds some distinctiveness. This sits at anchor 3 (somewhat specific but could still overlap with similar skills), not 4 (minor overlap risk only).
