fprime-component-integration-test

nasa/fprime/.github/skills/fprime-component-integration-test/SKILL.md

Integration testing phase of F Prime component development. Guides the agent through writing reusable pytest-based integration tests in the component's test/int/ folder using the GDS Integration Test API. These tests ship with the component and can be run against any deployment that includes it. Trigger when unit tests pass and the component is ready for integration testing. Keywords: F Prime, integration test, pytest, GDS, fprime_test_api, reusable test, component test.

hyhmrrightSkill

brooks-test

hyhmrright/brooks-lint/skills/brooks-test/SKILL.md

Test quality review drawing on twelve classic engineering books — with primary focus on xUnit Test Patterns, The Art of Unit Testing, How Google Tests Software, and Working Effectively with Legacy Code — that diagnoses structural problems in an existing test suite: brittleness, mock abuse, coverage illusions, slow execution, poor readability. Triggers when: user asks about test quality, shares test files for review, or expresses frustration: "tests keep breaking whenever I change anything", "our tests take forever", "tests pass but bugs still reach production", or "we have too many mocks". Do NOT trigger for: writing new tests from scratch (use the regular test-writing workflow) or testing framework/syntax questions — this skill reviews an existing suite for structural quality problems, not individual test authoring.

FracteraSkill

use-testing

Fractera/web4-node-starter-kit/.claude/skills/use-testing/SKILL.md

Build process. How work is PROVEN here — before you say «done», «it works», «ready to check». Load it when you are about to report a result, when a gate goes green and you feel finished, when something must be verified on the node, and when the owner asks for proof («show me the proof», «докажи»). The rule that changes behaviour: two proofs from DIFFERENT planes, one of them with a negative control, and a build log is never one of them — it reads the same whether the capability works or not.

CLAUDE.md vs AGENTS.md

About skills

What is a Claude skill?

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.

How do I use one I find here?

Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.

What do the warnings mean?

We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.

Which skills worked for people?

Open a skill to see its discussion. Reports from people and their agents are coming.
