Quality

Content

57%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is highly actionable with concrete templates and exact paths, and the workflow is clearly sequenced. However, it lacks validation checkpoints before the destructive deprecation move, is a monolithic single file with no progressive disclosure into references, and carries some conceptual padding.

Suggestions

Add an explicit validation/confirmation checkpoint before destructive operations — e.g., confirm the hypothesis file exists and verify with the user before running the `mv` in Deprecate, then re-verify the move succeeded.

Split the detailed freshness report format and the deprecation/waiver record templates into reference files (e.g. REPORT_FORMAT.md, TEMPLATES.md) with clearly signaled links from SKILL.md to improve progressive disclosure.

Trim the conceptual sections ('Key principle', 'Quick Concepts', 'WLNK Principle') to the minimum needed to frame the actions, reducing token cost while preserving the actionable workflow.

DimensionReasoningScore

Conciseness

The body is mostly task-oriented with concrete templates, but includes conceptual padding ('Key principle', 'Quick Concepts', 'WLNK Principle') that could be tightened, matching the 'mostly efficient with some unnecessary explanation' anchor.

3 / 5

Actionability

It provides copy-paste-ready report tables, deprecation/waiver record templates with exact frontmatter, concrete file paths, and a specific `mv` command, with only a minor gap ('Re-run validation to create fresh evidence' is vague), fitting the 'mostly executable with minor gaps' anchor.

4 / 5

Workflow Clarity

The three-step sequence (generate report, present, handle action) is clearly laid out, but the Deprecate action performs a destructive file move (`mv` between knowledge layers) with no validation or confirmation checkpoint, so per the feedback_loops note workflow clarity is capped at 3.

3 / 5

Progressive Disclosure

The skill is well-organized with clear section headers but is a single ~228-line file with no bundle files or external references, and content like the detailed report format and record templates could be split out, matching the 'some structure, content that should be separate is inline' anchor.

Description

53%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description clearly states the skill's purpose and domain but omits any 'Use when...' trigger guidance, which caps completeness. Specificity is decent though 'governance actions' is vague, and trigger terms miss common synonyms. It is a reasonably distinct niche with minor overlap risk.

Suggestions

Add an explicit 'Use when...' clause with concrete triggers, e.g. 'Use when managing FPF evidence freshness, when evidence nears or passes its valid_until date, or when the user mentions stale evidence, evidence decay, or expired decisions.'

Replace the generic 'providing governance actions' with the specific actions the skill performs (refresh, deprecate, waive) to lift specificity.

Include natural synonyms users would actually say — 'stale evidence', 'evidence decay', 'expired evidence' — to broaden trigger term coverage.

DimensionReasoningScore

Specificity

Names the domain ('evidence freshness') and two actions ('identifying stale decisions', 'providing governance actions'), but 'governance actions' is generic rather than concrete, matching the anchor for naming a domain with 1-2 actions that are not comprehensive.

3 / 5

Completeness

It gives a clear 'what' ('Manage evidence freshness by identifying stale decisions and providing governance actions') but has no 'Use when...' clause or equivalent trigger guidance, so per the rubric guideline completeness is capped at 3.

3 / 5

Trigger Term Quality

'stale decisions' and 'evidence freshness' are relevant domain keywords, but it misses common natural variations users would say ('stale evidence', 'evidence decay', 'expired evidence') and leans on jargon ('governance actions'), fitting the anchor for some relevant keywords missing common synonyms.

3 / 5

Distinctiveness Conflict Risk

The FPF evidence-freshness niche is mostly distinct with clear triggers, with only minor overlap risk against closely related evidence-management skills, fitting the 'mostly distinct' anchor above the midpoint.
