core

vercel-labs/agent-browser/skill-data/core/SKILL.md

Core agent-browser usage guide. Read this before running any agent-browser commands.

VercelSkill

derive-client

vercel-labs/agent-browser/skill-data/derive-client/SKILL.md

Reverse-engineer a website's internal API by recording browser traffic into a HAR file, then generate a standalone client or CLI that calls the endpoints directly, with no browser needed after the first recording. Use when asked to "derive a client", "build a CLI for <site>", "reverse engineer this site's API", "record network requests", "turn this site into an API", or when the same site will be automated repeatedly and direct HTTP calls would beat driving the browser every time.

AstralAGENTS.md

ruff

astral-sh/ruff/AGENTS.md

This repository contains both Ruff (a Python linter and formatter) and ty (a Python type checker). The crates follow a naming convention: ruff_* for Ruff-specific code and ty_* for ty-specific code. ty reuses several Ruff crates, including the Python parser (ruff_python_parser) and AST definitions (ruff_python_ast). Before starting work on an issue and again before opening a pull request, follow the guidance on avoiding duplicate work. If an open pull request already addresses the issue, do not submit a competing one…
