Conciseness

The ~40-line body is lean and assumes competence: it delegates review criteria to factory-review via skill_read instead of re-explaining them, gives bare git commands with no tutorial padding, and every sentence instructs. It matches anchor 5 ("every token earns its place") rather than 4, since there is no over-explanation left to trim.

Actionability

Guidance is mostly executable: copy-paste commands (`git rev-parse --abbrev-ref HEAD`, `git merge-base HEAD origin/<default branch>`, `base...HEAD`), a fully specified `factory_record_review_verdict` call with argument names, and a concrete report format. Minor gaps hold it at anchor 4 rather than 5 — the default branch is never determined for the reader, and steps like "load the category guidance" resolve only through the referenced skill's phases.

Workflow Clarity

The sequence is explicit (role guard → load criteria → checkout → report → verdict → stop) with validation checkpoints and feedback loops: "If it does not exist on `origin`, the builder never pushed: request changes", "confirm each one is fixed on this head before looking for new problems", and the verdict "repeated only if rejected and only with the stated reason addressed". The workflow is read/test/record (pushing and committing are explicitly forbidden), so the destructive/batch cap does not apply; anchor 5 fits.

Progressive Disclosure

The skill is under 50 lines with no bundle files, well-organized into scoped sections, and its only external dependency is a single clearly-signaled one-level reference ("Load `factory-review` with `skill_read`"). Per the rubric's simple-skill guideline this matches anchor 5.

Specificity

The description lists several concrete actions — "Review and test a Factory work item's pushed branch", "record the verdict", "sends it back to Building or on to open the change request" — with a conditional routing outcome. It matches anchor 4 rather than 5 because coverage has minor gaps (e.g., producing the findings report is never mentioned), and it exceeds anchor 3's 1-2 concrete actions.

Completeness

The "what" is clear (review, test, record verdict with routing), and a "when" is explicitly stated via "before any pull or merge request exists". It sits at anchor 4 rather than 5 because the when-condition could be more specific — the body's role/stage trigger (role="review", stage review, no open PR) is not reflected, and there is no "Use when..." style trigger phrase.

Trigger Term Quality

Good natural keyword coverage: "review", "test", "branch", "pull or merge request" (covering both PR and MR variants), and "Factory work item". A few natural terms are missing (e.g., "self-review", "pre-PR"), which keeps it at anchor 4 rather than 5, but coverage clearly exceeds anchor 3's partial keyword set.

Distinctiveness Conflict Risk

"Factory work item's pushed branch before any pull or merge request exists" carves a clear niche with distinct triggers, distinct from generic code-review or PR-review skills. Overlap risk is minimal, matching anchor 5 rather than anchor 4's "minor overlap risk with closely related skills".
