kortix-aiSkilltesting
kortix-ai/suna/.agents/skills/testing/SKILL.md

Model Context ProtocolSkilltesting
modelcontextprotocol/inspector/.claude/skills/testing/SKILL.md
Run, place and fix tests in this repo. Use when choosing which npm command runs a given suite (web unit, web integration, Storybook, cli, tui, launcher, scripts); when deciding where a new test file belongs — beside its source, under src/test/, or in a client's __tests__/; when a per-file coverage check fails or a v8 ignore is in question; when asking which test tier spawns the built binary rather than importing it; or when rendering, mounting or asserting on Mantine components and their transitions in a test.

manaflow-aiSkillcmux-testing
manaflow-ai/cmux/skills/cmux-testing/SKILL.md
Choose scoped cmux verification, add behavioral tests, and validate Swift test targets and wiring. Use when adding tests or deciding what local/CI evidence a change needs.
AnthropicSkilltesting-strategy
anthropics/knowledge-work-plugins/engineering/skills/testing-strategy/SKILL.md
Design test strategies and test plans. Trigger with "how should we test", "test strategy for", "write tests for", "test plan", "what tests do we need", or when the user needs help with testing approaches, coverage, or test architecture.
SentrySkillreact-testing

Testing strategy for Supabase Studio. Use when writing tests, deciding
PostHogSkillwriting-tests
PostHog/posthog/.agents/skills/writing-tests/SKILL.md
Gates whether a new test should exist and forces it to be efficient, protecting CI from low-value test bloat. Use before any change to what a pytest, Jest, or Playwright test asserts or sets up, down to one fixture or one assertion added to an existing block. Front-loads the value bar (every test must catch a realistic regression no existing test already catches; extend the nearest existing test before writing a new standalone one; test behavior through the public interface, not implementation details; collapse near-duplicates into parameterized cases) and the efficiency bar (deterministic, isolated, fast; pick the cheapest test level; Django TestCase over TransactionTestCase; no sleeps, no real network; no time bombs from absolute dates left to age against the real clock; no database a test never uses). Includes a "don't write it" decision tree. For fixing an existing flaky test use `/fixing-flaky-tests`; after this gate says a Playwright test is warranted, use `/playwright-test` for mechanics.
GitHubSkillwebapp-testing

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.
