Guidelines for AI agents working on the Vercel monorepo. This is a pnpm monorepo containing 44+ packages for the Vercel CLI and runtimes: Run tests for a specific package: Always create a changeset for all PRs. A changeset is a markdown file in .changeset/ with YAML frontmatter listing affected packages and their bump type (patch/minor/major). Example changeset for a package change: Example changeset for an internal package (the public packages that bundle it are added at version time): Example changeset…

Always-loaded guidance for work inside packages/cli. Keep this file small. The CLI UX design system lives in packages/cli/.agents/skills/cli-ux/ and should be loaded only when the task or code review touches user-facing CLI behavior. Common shared areas:
VercelSkillcli-ux
vercel/vercel/packages/cli/.agents/skills/cli-ux/SKILL.md
Vercel CLI design system, the north-star standard for command names, options, help, prompts, output, copy, errors, JSON, exit codes, and agent/CI behavior in packages/cli. Use when designing, implementing, or reviewing any user-facing CLI surface. Skip implementation-only refactors that leave the CLI surface unchanged.

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.
