Autocss-comSkill

testing

Autocss-com/ai/.agents/skills/testing/SKILL.md

How to verify AutoCSS work before it ships, in a zero-dependency architecture. Covers the air-gap test, driving the real app in a browser to observe behavior, verifying CSS-only state/visibility, and the accessibility passes. Test tooling is dev-only and never enters the shipped static shell. Use before committing any nontrivial change, or when asked to confirm something works.

matejformanekSkill

testing

matejformanek/postgres-claude/.claude/skills/testing/SKILL.md

Pick the right PostgreSQL test flavor for a core / contrib patch — covers pg_regress .sql / .out pairs, isolationtester specs and permutations for concurrency / deadlock races, TAP (PostgreSQL::Test::Cluster) for multi-node and pg_basebackup / replication / recovery scenarios, and src/test/modules for in-tree C test modules. Spans where test files live, how to wire them into the right schedule / meson.build, and how to run a single test fast (REGRESS_OPTS, --temp-instance, PROVE_FLAGS). Use whenever adding tests to a PG patch, reviewing a patch's test coverage, picking between regress / isolation / TAP for a new feature, debugging a regression diff, or asked "where should the test for X live". Skip for pytest / unittest / Jest / Vitest / Mocha / RSpec / JUnit / Go testing / Rust cargo-test app testing, pgbench / sysbench / HammerDB performance benchmarking, end-to-end / Selenium / Playwright web testing, and load / stress testing of production PG.

CLAUDE.md vs AGENTS.md

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.
