Conciseness

The body is mostly efficient (typed input spec, output template, compact examples) but contains redundant sections: "Standard Metrics" and Step 5's "Optional Fields" re-list fields already defined in Step 1 (Timestamp, Duration, Workflow, Phase), and the Supporting Files line is circular. Multiple padded/redundant sections rather than minor trims place it at 3, not 4.

Actionability

Fully concrete and executable for an instruction skill: typed expected-input fields with examples, an exact output markdown template, a status-to-emoji mapping table, a timestamp format spec, and four complete input→output examples covering success, partial, and failed cases. This matches the 'fully executable, covers common cases' anchor.

Workflow Clarity

A clear five-step sequence with an Error Handling section providing recovery paths (e.g., "Invalid Timestamp: Use current time and warn"). However, the Validation section is a post-hoc checklist rather than an in-workflow checkpoint, and there is no step verifying the generated header against the template, so it falls short of the explicit-checkpoint anchor of 5.

Progressive Disclosure

Sections are well-organized with clear headers, but the only external reference — "`template.md`: Report header template (see Supporting Files section)" — points to a file that does not exist in any bundle directory and uses a circular self-referencing description. A dangling reference plus ~150 lines of examples that could live in a separate file matches the 'references present but not clearly signaled / could be better organized' anchor of 3, not 4.

Specificity

"Create standardized report headers with metadata" names the domain with 1-2 concrete actions but no broader action coverage, matching the 'Names domain and 1-2 concrete actions' anchor. It does not list several specific actions (e.g., formatting timestamps, mapping statuses, embedding metadata), so it is not a 4.

Completeness

Explicitly answers both what ("Create standardized report headers with metadata for all agent-generated reports") and when ("Use when generating bug reports, security audits, dependency reports, or any worker output requiring consistent formatting") with concrete trigger phrases, matching the anchor-5 example pattern. The when-clause is fully explicit, not merely present, so it is above the 4 anchor.

Trigger Term Quality

Includes good natural trigger terms users would say — "bug reports", "security audits", "dependency reports", "consistent formatting" — but misses common variations such as "summary", "validation report", or "audit report header". Coverage is good but not comprehensive, so 4 rather than 5.

Distinctiveness Conflict Risk

The niche (headers for agent-generated reports) is mostly distinct with targeted triggers like "bug reports" and "worker output". There is minor overlap risk with general document-formatting or report-writing skills, so it does not reach the clear-niche anchor of 5.
