Conciseness

The body is lean and dense: every sentence carries a command, path, exit code, or policy ("Exit 0 is a complete run; 1 means a case errored or timed out... 3 that no harness is recorded"), with no concept explanations Claude already knows and nothing to trim.

Actionability

Complete, copy-paste-ready commands are given for each mode ("uv run {skill-root}/scripts/run_evals.py --cases <cases-file> --skill-path <skill> --output-dir <dir> --mode quality|baseline|variant [--variant-path <skill>]") plus config-resolution, conversion, and aggregation commands, covering all common cases.

Workflow Clarity

"On activation" is a numbered sequence with explicit validation checkpoints ("halt with a clear error if not", "If nothing is found, halt and say so"), exit-code semantics, and error-recovery feedback loops (a grader error marks the case `grading_error`, "never a default verdict").

Progressive Disclosure

The body is a clear overview — a mode table mapping each mode to its script and reference — with deep material explicitly delegated one level deep to real bundle files ("The full shape and the strong-versus-weak expectation taxonomy are in references/eval-format.md", plus grader.md, harness.md, description-optimization.md, self-improvement.md), all of which exist.

Specificity

The description enumerates four concrete, distinct capabilities — "baseline against the bare model, variant against a stripped or prior version, quality against a rubric, and trigger accuracy of the description with an optional optimization loop" — which is comprehensive coverage of the skill's modes rather than minor gaps.

Completeness

It explicitly answers what ("Runs the evals of a BMad skill through the agent harness the user works in and reports what they show") and when ("Use when the user asks to evaluate, benchmark, test the triggers of, grade, or compare versions of a skill") with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

Natural phrases like "evaluate, benchmark, test the triggers of, grade, or compare versions of a skill" give good synonym coverage, but a few natural user phrasings (e.g., "run the evals", "test this skill") are missing, placing it at the 4 rather than 5 anchor.

Distinctiveness Conflict Risk

The BMad-skill eval niche is clear, but the trigger clause "of a skill" is generic enough that requests to evaluate or benchmark any skill could overlap with other evaluation skills — minor overlap risk, matching the 4 anchor rather than the minimal-conflict 5.
