antithesis-setup

Scaffold the Antithesis harness with docker-compose: initialize the working directory, write Dockerfiles and docker-compose.yaml with build directives, and prepare to submit your first Antithesis test run. If the desired setup is Kubernetes, defer to the antithesis-setup-k8s skill.

Quality

Content

83%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 SKILL.md body is well-organized, directive, and uses progressive disclosure effectively with a clear sequenced workflow, validation checkpoints, and a strong self-review checklist. Its main weakness is mild redundancy in the launch-deferral guidance and the fact that executable specifics live in reference files rather than inline.

DimensionReasoningScore

Conciseness

The body is directive and assumes Claude's competence without explaining basic concepts, but repeats the 'use antithesis-launch, not snouty launch directly' guidance three times and could be tightened slightly, fitting 'efficient with minor instances that could be trimmed' rather than fully lean.

4 / 5

Actionability

It points to concrete reference files, specific commands (snouty validate, snouty doctor, compose build), paths, and env vars, but delegates most executable detail to the reference files rather than embedding copy-paste-ready code in the body, leaving minor gaps.

4 / 5

Workflow Clarity

Steps are clearly sequenced (directory-init → instrumentation → docker-images → docker-compose → config-dir → submit-and-test) with an explicit revisit-after-each-step feedback loop, mandatory provenance confirmation before durable output, and snouty validate/build checkpoints, plus a thorough Self-Review checklist — matching the explicit-validation anchor.

5 / 5

Progressive Disclosure

The body is a clear overview with well-signaled, one-level-deep references to real reference files (references/*.md) and assets (assets/antithesis/), each introduced with its purpose, giving easy navigation without nested indirection.

Description

63%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 specific and clearly distinct from sibling skills, but it omits any explicit 'Use when...' trigger guidance, which caps completeness at 3. It reads as a strong 'what' statement with a useful deflection note rather than a fully trigger-qualified description.

Suggestions

Add an explicit 'Use when...' clause naming natural user triggers, e.g. 'Use when setting up or scaffolding an Antithesis harness with docker-compose, or when the user asks to initialize an Antithesis project.'

Surface a few more natural trigger terms users would actually say (e.g. 'Antithesis setup', 'Antithesis project', 'compose harness') to broaden trigger-term coverage beyond specialized jargon.

DimensionReasoningScore

Specificity

Names several concrete actions — 'initialize the working directory', 'write Dockerfiles and docker-compose.yaml with build directives', 'prepare to submit your first Antithesis test run' — with only minor coverage gaps, fitting the 'several specific actions' anchor rather than the fully comprehensive 5.

4 / 5

Completeness

It clearly states what the skill does but offers no explicit 'Use when...' trigger clause, and the 'if the desired setup is Kubernetes, defer...' sentence is a deflection rather than a when-condition, so the missing-trigger cap applies.

3 / 5

Trigger Term Quality

Includes natural domain terms a user would say ('Antithesis harness', 'docker-compose', 'Dockerfiles', 'Kubernetes') but leans on specialized jargon and lacks broader synonyms/extensions, placing it just below comprehensive coverage.

4 / 5

Distinctiveness Conflict Risk

It carves a clear niche (Antithesis docker-compose setup) and explicitly distinguishes itself from the sibling k8s skill, giving it distinct triggers with minimal conflict risk.
