A drop-in AGENTS.md file that makes coding agents behave like senior engineers, eliminating sycophancy and forcing verification.
A CLI tool to package and deploy consistent AI coding environments across multiple assistants.
Curated AI coding agent skills and playbooks for Codex, Claude Code, Cursor, OpenClaw, and other SKILL.md-compatible tools.
AGENTS.md rules and skills for AI coding agents, distilled from classic software engineering books.
agentsync is a command-line tool that keeps your AI coding-agent rules in sync. You write rules in one file (like AGENTS.md) and it automatically converts them to other formats like CLAUDE.md, .cursorrules, or Copilot instructions. It also checks for errors and can set up a pre-commit hook so everything stays updated.
agentsync (formerly ai-rules-sync) is a zero-dependency CLI tool that converts between AI coding-agent rule file formats: AGENTS.md (Codex), CLAUDE.md (Claude Code), .cursorrules (Cursor), .github/copilot-instructions.md (Copilot), .windsurfrules (Windsurf), and more. It can also scaffold a fresh AGENTS.md by scanning your project or from explicit fields. The tool supports one-command setup (agentsync setup) that generates a config, runs the first sync, and installs a git pre-commit hook. With --auto mode, you can edit any rule file and agentsync detects the change and regenerates the rest. It also includes linting to check for stale commands or missing paths. The same engine powers both the CLI and a browser playground. It requires Node.js >=18 and is published on npm as @panishandsome/agentsync.

Convert and sync AI coding-agent rule files between formats with zero dependencies.
Developers using multiple AI coding agents (Codex, Claude Code, Cursor, Copilot)., Tech leads who want a single source of truth for project rules., Open-source maintainers who need to support various AI tools.
The setup section provides repository-level starting guidance, not a guarantee of an independently verified installation. Check the official README and release notes.
Agent instruction templates should be reviewed before use because they can change coding-agent behavior across an entire repository. Avoid copying rules that grant broad filesystem, shell, network, or secret access without adapting them to your project.
Similar or complementary options to evaluate include agents-md, rulebook-ai, ok-skills.
