verify

Confirm a story is actually done. Walk acceptance criteria against the implementation, check test coverage at the right layer, identify edge cases the tests miss. Adversarial about "done" — does not take coverage claims on trust.

Discovery

67%

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 is strong in specificity and distinctiveness, clearly articulating a unique skill around verifying story completion with concrete actions like walking acceptance criteria and identifying missed edge cases. Its main weaknesses are the lack of an explicit 'Use when...' clause and missing some natural trigger terms users might employ when requesting this type of review.

Suggestions

Add an explicit 'Use when...' clause, e.g., 'Use when the user asks to verify a story is done, review acceptance criteria, check definition of done, or validate story completion.'

Include additional natural trigger terms like 'definition of done', 'DoD', 'verify completion', 'story sign-off', 'QA review', or 'ready for release'.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: walking acceptance criteria against implementation, checking test coverage at the right layer, identifying edge cases tests miss, and being adversarial about 'done' claims.

3 / 3

Completeness

Clearly answers 'what does this do' with specific actions, but lacks an explicit 'Use when...' clause or equivalent trigger guidance. The 'when' is only implied by the nature of the actions described.

2 / 3

Trigger Term Quality

Contains relevant terms like 'story', 'acceptance criteria', 'test coverage', 'edge cases', and 'done', but misses common user variations like 'definition of done', 'DoD', 'story review', 'QA check', 'verify completion', or 'sprint review'.

2 / 3

Distinctiveness Conflict Risk

Occupies a clear niche around story completion verification and acceptance criteria validation. The combination of acceptance criteria checking, test coverage analysis, and adversarial 'done' verification is distinctive and unlikely to conflict with general code review or testing skills.

Implementation

77%

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

This is a well-crafted verification skill with excellent actionability and workflow clarity. The three-move framework is concrete and the failure modes section shows sophisticated understanding of common verification pitfalls. The main weaknesses are moderate verbosity (the stance section and some failure mode descriptions could be tighter) and inline content that might benefit from being split into reference files for better progressive disclosure.

Suggestions

Trim the 'Your Stance' section — the adversarial posture is already conveyed by the three moves and failure modes; the philosophical framing adds tokens without new information.

Consider moving 'Failure Modes' and 'Cross-plugin context' to separate reference files to keep the main skill leaner and improve progressive disclosure.

DimensionReasoningScore

Conciseness

The content is mostly efficient and well-structured, but includes some sections that could be tightened — the 'Your Stance' section restates concepts already implied by the skill's purpose, and the 'What Verify Does NOT Do' section, while useful for boundary-setting, is somewhat verbose. The failure modes section adds value but could be more compact.

2 / 3

Actionability

The skill provides highly concrete, actionable guidance: the three-move framework gives specific steps (walk each AC individually, name the test by file and name, mentally mutate the implementation), the structured report format is clearly defined with exact categories, and the transitions section gives precise handoff triggers with example phrasing.

3 / 3

Workflow Clarity

The three-move workflow is clearly sequenced (walk ACs → check test layer → identify gaps), includes explicit validation checkpoints (mental mutation testing, layer-appropriateness checks), and has a clear verdict framework with specific criteria for done/almost done/not done. The transitions section provides clear feedback loops for each type of gap discovered.

3 / 3

Progressive Disclosure

The skill references several external files (foundation/SKILL.md, foundation/model.md, foundation/guidelines.md, quality-engineer agent) which is good for navigation, but no bundle files are provided to verify these exist. The content itself is somewhat long and could benefit from splitting the failure modes or cross-plugin context into separate reference files rather than inlining everything.
