LoveforwaSkillLoveforwa/spec-test.skill/en/SKILL.md
Use specification-based testing methodology for end-to-end testing of web applications. Use this skill when users request "test this feature", "check this feature completeness", "do E2E testing on this project", "test this web app with an agent", or directly mention spec-driven-test / specification-based testing. This skill also applies to scenarios where users want to automatically generate test specs and test cases from code, then execute tests through browser automation. Even if users don't explicitly mention "spec" or "test case", if they want to systematically and automatically test a specific feature of a web project, this skill should be used.

Guides automated testing of SPIP plugins and squelettes using PHPUnit — the standard test tool for SPIP. Covers the full self-contained setup (composer, spip-cli), unit tests with lightweight mocks, and integration tests against a real SPIP instance. Use whenever the user wants to test, verify, or validate a SPIP plugin or squelette — even if they don't mention PHPUnit — including questions like "how do I test my plugin", "I want to make sure my filtre works", or "how do I write tests for my autorisation / CVT form / #BALISE".
netresearchSkillnetresearch/typo3-testing-skill/skills/typo3-testing/SKILL.md
Use when a reported defect has to be reproduced as a failing test before it is fixed, when a change to a template or to any rendered output has to be proved, or when setting up TYPO3 extension test infrastructure, writing unit/functional/E2E tests, configuring PHPUnit 11/12/13, mutation testing, mocking final classes (v14), CI/CD matrix across TYPO3 12/13/14.3 LTS, dev-dependency consolidation via typo3-ci-workflows meta-package, or debugging CI failures. Also triggers on: testing-framework setup, ensure proper testing, test matrix, integration testing, e2e testing, coverage, test generation.
SensorsIotSkillSensorsIot/Embedded-AI-Harness/.claude/skills/testbench-test-handling/SKILL.md
Use this skill when running or writing automated tests against the testbench — the three-phase execution protocol every test case follows, live progress on the Pi's web UI, blocking prompts for physical operator actions (button press, cable swap, power cycle), the TestbenchDriver Python API, and activity log queries. Use it for authoring a pytest suite as well as for tracking a manual run. For driving one instrument, use that instrument's skill instead. Triggers on "test progress", "test session", "test spec", "test case", "test harness", "run the tests", "write a test", "TestbenchDriver", "human interaction", "operator", "activity log", "test panel".
tercelSkilltercel/spec-forge/skills/test-plan-generation/SKILL.md

This skill activates when the user asks to write a test plan, create test cases, draft a test plan document, create a test cases document, define a test strategy, write a QA document, produce a testing document, draft a test specification, or build a quality assurance plan. It produces comprehensive, structured test documentation that ensures thorough coverage, traceability to requirements, and a clear path from test design through execution and defect management.

Static inspection of HTML/JSX is NOT verification of a web deliverable.

Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.
CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.
A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.
Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
