nest-test

Creates NestJS backend tests with Vitest — unit specs with stubbed repositories, and Supertest end-to-end specs that boot the application against a real PostgreSQL database in Testcontainers. Use when the user asks to "write backend tests", "test the API", "write an e2e test", "test the endpoint", or mentions Supertest, Testcontainers, NestJS testing, or Vitest for a NestJS project.

Quality

Content

88%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 body is highly actionable and well-structured, delivering executable code and a validated multi-step workflow focused on real NestJS+Vitest failure modes. It is mostly concise, with only minor opportunities to trim explanatory prose.

Suggestions

Tighten the prose around the Testcontainers lifecycle constraints and the non-deterministic-inputs section to lift conciseness toward 5.

Consider moving the full unit/e2e example specs into a references/ file if the skill grows, to keep SKILL.md an overview while preserving progressive disclosure.

DimensionReasoningScore

Conciseness

The body is mostly lean and assumes Claude's competence, focusing on non-obvious gotchas (decorator metadata under Vitest, oxc default in Vite 8, fileParallelism off); a few explanatory prose passages could be trimmed further.

4 / 5

Actionability

Provides fully executable, copy-paste-ready code blocks (vitest.config.ts, global-setup.ts, create-app.ts, unit and e2e specs, fake timers) and concrete commands like 'npx vitest -t "UC-010"'.

5 / 5

Workflow Clarity

An 8-step numbered workflow with explicit validation checkpoints (check vitest config before tests, reconcile existing tests, run the whole file, confirm Docker daemon if e2e fails to start) gives clear sequencing and error-recovery feedback loops.

5 / 5

Progressive Disclosure

No bundle files exist, but the body is well-organized into clear sections with one-level-deep external references (project-layout.md, mcp-servers.md); full inline code examples are appropriate for a code skill, though some could conceivably live in references.

Description

100%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 exemplary: it states concrete capabilities, gives explicit natural-language trigger phrases, and is tightly scoped to a NestJS testing niche with low conflict risk. Both 'what' and 'when' are answered clearly.

DimensionReasoningScore

Specificity

Names multiple concrete actions — 'unit specs with stubbed repositories' and 'Supertest end-to-end specs that boot the application against a real PostgreSQL database in Testcontainers' — with comprehensive coverage.

5 / 5

Completeness

Explicitly answers both 'what' (creates unit and e2e NestJS tests with Vitest) and 'when' via a clear 'Use when the user asks to...' clause with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural quoted phrases users would say ('write backend tests', 'test the API', 'write an e2e test', 'test the endpoint') plus technology keywords (Supertest, Testcontainers, NestJS testing, Vitest) and synonyms.

5 / 5

Distinctiveness Conflict Risk

Targets a clear niche — NestJS projects tested with Vitest/Supertest/Testcontainers — with specific triggers and minimal overlap with unrelated skills.
