Quality

Content

61%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 body is concise and gives concrete locations and tooling for placing tests, but it is rules-based rather than sequenced and omits executable examples and a run/verify checkpoint. Adding a minimal usage example and a verification step would meaningfully strengthen it.

Suggestions

Add a brief, executable example showing how to use test_codex to set up a test instance and how to run the integration tests under core/suite.

Append an explicit verification step, e.g. "Run the new test and confirm it passes before considering the change complete," to close the workflow's validation gap.

Group the rules under short section headers (e.g. ## When to add tests, ## Where tests go) to make the short doc easier to navigate.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence without re-explaining concepts; only minor trimming is possible (e.g. "to make tests more streamlined and readable"), matching the efficient-with-minor-trim anchor.

4 / 5

Actionability

It gives concrete specifics (core/suite, test_codex, *_tests.rs) but is incomplete: no usage or run example for test_codex, and the "Provide a list of major logic changes" bullet is vague guidance rather than executable instruction.

3 / 5

Workflow Clarity

The content is a set of parallel rules rather than a clear sequence, and it lacks any verification checkpoint such as running the tests and confirming they pass, matching the sequence-present-but-validation-gaps anchor.

3 / 5

Progressive Disclosure

For a short, single-purpose skill with no need for external references, the content is appropriately placed with only minor organization gaps (no section headers), fitting the good-structure anchor.

Description

28%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 is a terse topic label rather than a capability statement: it names the test-authoring domain but gives no concrete actions, natural trigger phrases, or explicit use-when guidance. It is minimally informative and at high risk of not surfacing when needed.

Suggestions

Rewrite the description to state concrete actions, e.g. "Write and place integration and unit tests for agent changes under core/suite using test_codex."

Add an explicit trigger clause: "Use when adding or modifying agent logic that needs test coverage, or when the user asks to write tests for codex changes."

Include natural trigger terms users would actually say ("writing tests", "integration tests", "unit tests") to improve discoverability and distinctiveness.

DimensionReasoningScore

Specificity

The description "Test authoring guidance" names the domain (tests) and a minimal generic action (authoring) but lists no concrete capabilities. It is above the score-1 anchor because it names a domain, but below 3 since there are no specific concrete actions.

2 / 5

Completeness

It provides a vague "what" (test authoring guidance) and no "when" or "Use when..." trigger clause, matching the anchor for a vague what with no when and respecting the missing-trigger cap of 3.

2 / 5

Trigger Term Quality

It offers only one or two generic keywords ("test", "authoring") and misses the natural phrases a user would say, such as "writing tests", "integration tests", or "unit tests".

2 / 5

Distinctiveness Conflict Risk

"Test authoring" is a somewhat specific niche, but with no explicit triggers it could still overlap with other testing-related skills, fitting the somewhat-specific anchor.
