Conciseness

The body is 14 lines with no concept explanations and no padding: an exact command, placeholder substitution rules, and three contingency bullets. Every token is load-bearing ("exactly once", "without changing the current working directory", "Do not run any workflow source directly"), matching anchor 5 rather than 4, which expects trimmable over-explanation.

Actionability

The skill provides a fully executable command with explicit placeholder-substitution instructions, and error paths are handled with concrete commands ("npx skills add bmad-code-org/BMAD-METHOD --skill bmad") and unambiguous directives (report and HALT). This matches anchor 5's copy-paste-ready guidance covering the common cases.

Workflow Clarity

This is a simple single-task skill and the one action is unambiguous, so the simple-skill exception applies. Beyond that, each failure branch is explicitly sequenced: script not found -> offer setup (install if needed) -> rerun once; HALT output -> report and stop; any other failure -> report and HALT. No destructive or batch operations are involved, so no validation cap applies.

Progressive Disclosure

The skill is well under 50 lines with no inlined bulk content and no external references to organize; per the rubric's simple-skill guidance this scores 5. Deferring the actual workflow to the rendered output is itself well-signaled one-level-deep disclosure ("The command prints the skill's workflow: follow it").

Specificity

"Guide a human review of a commit, PR, file, or directory" names the domain and one concrete action with specific targets, but does not list several distinct actions (e.g., what the review involves or produces). It fits anchor 3 (domain plus 1-2 concrete actions) rather than 4, which requires multiple specific actions, and the action is too concrete for anchor 2's generic-minimal bar.

Completeness

Both parts are present: "Guide a human review of a commit, PR, file, or directory" answers what, and "Use when invoked by name" is an explicit when clause, so the missing-trigger cap at 3 does not apply. It is not a 5 because the when clause gives no concrete trigger phrases (e.g., when the user asks to review a commit or PR).

Trigger Term Quality

"commit, PR, file, or directory" plus "review" are natural terms users would say, comparable to anchor 4's "PDF files, forms, document extraction". It falls short of anchor 5 because common variations like "pull request", "diff", "changes", or "code review" are missing.

Distinctiveness Conflict Risk

The "human review" framing and name-only invocation ("Use when invoked by name") carve a fairly distinct niche, but "review of a commit, PR, file, or directory" overlaps with code-review-style skills. This matches anchor 4 (mostly distinct, minor overlap risk with closely related skills) rather than 5's clear-niche bar.
