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.

dylanroscover/Embody/.claude/skills/testing/SKILL.md

MUST READ before declaring any TouchDesigner build, fix or show done, and before any soak or performance test: the verification ladder (structure, errors, frame, motion, data, performance, soak, end to end), run_soak_test and the observer-effect rules that keep measuring from perturbing the show, the iterate-by-capture loop, and what done means.

VeryGoodOpenSourceSkill

testing

VeryGoodOpenSource/vgv-ai-flutter-plugin/skills/testing/SKILL.md

Best practices for Dart unit tests, Flutter widget tests, and golden file tests, covering group and test naming, setUp lifecycle and isolation, mocking with package:mocktail, and the shared pumpApp helper. Use when writing, modifying, or reviewing tests, goldens included, that use package:test, package:flutter_test, package:mocktail, or package:bloc_test. Use it also when no package is named: "add a golden test for my AppButton widget", "write a goldens test", goldens, matchesGoldenFile, tagging or updating goldens, writing a unit test or widget test, or adding a test helper or mock. A one-line golden or widget test request is in scope, including under "Dart code only"; a widget in a UI package is ui-package's. Use it too when the request asks for what these standards forbid: package:mockito, a raw string test tag instead of TestTag, an inline pumpWidget(MaterialApp(...)), asserting padding, color or font size in a widget test, or state shared between tests. Those requests are in scope, not out of it.

Agent instruction files

What are agent instruction files?

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 or AGENTS.md?

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.

What is a skill?

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.

Can I search my own team's files too?

Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
