internal-dev-workbench

vercel/workflow/skills/internal-dev-workbench/SKILL.md

Spin up a portless + tmux dev session for the Workflow SDK that gives each git worktree isolated `<branch>.<name>.localhost` URLs for the Next.js workbench and the observability UI, plus a Claude statusline that surfaces those URLs. Use only when the user asks for a "portless dev session", a "tmux dev layout for workflow", "worktree-isolated dev URLs", or wants to wire workflow dev URLs into the Claude statusline. Do not activate for the generic "start the dev server" / "run pnpm dev" task.

Use when porting Activities, Workers, Signals, step.run(), step.waitForEvent(), Trigger.dev tasks / wait.forToken / triggerAndWait, ASL JSON state machines, Task/Choice/Wait/Parallel states, task tokens, or child workflows.

workflow

vercel/workflow/skills/workflow/SKILL.md

workflow / nextjs-turbopack

vercel/workflow/workbench/nextjs-turbopack/AGENTS.md

This version has breaking changes — APIs, conventions, and file structure may all differ from your training data. Read the relevant guide in node_modules/next/dist/docs/ (resolved from this file's directory; in monorepos the next package may not be visible from the repo root) before writing any code. Heed deprecation notices. This block is written and re-added by next dev — verify at node_modules/next/dist/server/lib/generate-agent-files.js. Removing it from a diff only re-creates the uncommitted change; committing it with your work keeps the tree…

vercel/chat/AGENTS.md

Guidance for coding agents working in this repository. For PR workflow, signed commits, and changeset rules, see .github/CONTRIBUTING.md. Install dependencies with pnpm add, not by editing package.json by hand. pnpm + Turborepo monorepo. Packages are ESM ("type": "module"), TypeScript, bundled with tsup. When editing a specific package, read its AGENTS.md if present (most adapters, state packages, create-chat-sdk, and packages/catalog have one). {adapter}:{channel}:{thread} — e.g. slack:C123ABC:1234567890.123456. Some adapters base64-encode IDs that contain delimiters (Teams, Google Chat). mdast is the canonical message…

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.
