petrkindlmann/qa-skills/AGENTS.md

How AI agents should discover, load, and use skills from this repository. On first skill use per session: 1. Check for .agents/qa-project-context.md in the user's project root - If exists: read it and use as context for all subsequent skill interactions. A file whose fields are still the template's placeholders answers nothing; treat it as absent, take context from the project's own contract and configuration, and say so in the report - If not: suggest the user creates one using…

agentic-browser-testing

petrkindlmann/qa-skills/skills/agentic-browser-testing/SKILL.md

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.
