Stop your AI coding agent from wasting tokens and ignoring your conventions. One command scaffolds stack-aware rules files so Claude Code, Cursor, and Copilot work the way your project expects.
Run Agent Rules: Generate rules files for this workspace from the Command Palette
(Ctrl/Cmd+Shift+P). It will:
- Detect your stack (Next.js, React, Vue, Express, Python, Go, Rust, TypeScript, your package manager, test runner, linters, Tailwind, Prisma, …).
- Let you pick which files to create: CLAUDE.md, AGENTS.md, .cursorrules, and
.github/copilot-instructions.md. - Write best-practice, stack-specific rules — commands, conventions, and "don't do this" guardrails your agent will actually follow.
Run Agent Rules: Sync rules from one source to all agents to pick one file as the source of
truth and mirror its content to the others. Edit your rules once; Claude Code, Cursor, and Copilot
all stay on the same page — no more drift between AI runtimes.
No account, no telemetry, fully local.
Without a rules file, agents re-read files, reinvent utilities, refactor things you didn't ask
about, and burn tokens. A good CLAUDE.md / AGENTS.md / .cursorrules is the single highest-leverage
file in an AI-assisted repo — and this writes a solid first draft in two seconds.
This generates a strong baseline. If you want battle-tested, role-specific config packs (framework presets, MCP server setups, sub-agent definitions, and review checklists), grab the Agentic Coding Starter Kit.
