Quality

Content

85%

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

The content is a well-structured, actionable multi-step skill with clear sequencing, explicit validation checkpoints, a self-review checklist, and clean one-level-deep progressive disclosure; its only weakness is mild verbosity in the prerequisites/provenance sections.

Suggestions

Condense the 'Verify research provenance' example phrasings into a compact table or a single representative example to reduce token load.

Avoid restating the same constraint in multiple sections (e.g., 'use antithesis-launch, not snouty launch directly' appears in Purpose, General Guidance, and Self-Review) — cite once and reference it.

Dimension	Reasoning	Score
Conciseness	The body is mostly efficient and actionable, but the provenance/examples block in Prerequisites and several restated caveats could be tightened, fitting the 'mostly efficient but could be tightened' anchor.	2 / 3
Actionability	Guidance is concrete and specific — 'Set NO_COLOR=1 on all services via docker-compose.yaml environment blocks', 'Run compose build before snouty launch', 'snouty validate on antithesis/config/' — with specific file paths and commands throughout, satisfying the actionable instruction-only case.	3 / 3
Workflow Clarity	A clear six-step sequence is given ('Read and implement each reference file listed below one at a time') with an explicit re-validation loop ('check whether what you learned invalidates any decisions from earlier steps') plus a Self-Review checklist, matching the top anchor.	3 / 3
Progressive Disclosure	The body is an overview that signals one-level-deep references (references/directory-init.md, instrumentation.md, docker-images.md, docker-compose.md, config-dir.md, submit-and-test.md), all of which exist as real files, with language detail split under references/language/.	3 / 3

Description

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 specific and clearly niche, but it omits any explicit 'when to use' trigger guidance, capping completeness and trigger-term quality at the middle level.

Suggestions

Append a 'Use when...' clause stating when to invoke this skill (e.g., 'Use when setting up or re-initializing an Antithesis test harness for a project').

Add natural trigger variations users would actually say, such as 'Antithesis setup', 'Antithesis getting started', or 'set up Antithesis testing'.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'initialize the working directory, write Dockerfiles and docker-compose.yaml with build directives, and prepare to submit your first Antithesis test run' — matching the highest anchor.	3 / 3
Completeness	The 'what' is clearly stated, but there is no 'Use when...' clause or equivalent explicit trigger guidance, which the rubric caps at 2.	2 / 3
Trigger Term Quality	'Antithesis', 'Dockerfiles', and 'docker-compose.yaml' are relevant domain terms a user might say, but common variations and explicit trigger phrasing are absent, so it lands at the middle anchor.	2 / 3
Distinctiveness Conflict Risk	'Scaffold the Antithesis harness' names a clear niche with distinct triggers unlikely to fire for unrelated skills.	3 / 3
