This Skill addresses the lack of unified specification guidance for AI coding assistants within a project context. In real-world development, developers often need to manually write AGENTS.md files to inform AI agents about project structure, command conventions, coding standards, etc. However, this is costly to maintain and prone to omissions. This Skill automatically scans a project to generate a context file that complies with the agents.md standard, ensuring AI agents always receive the latest and most complete project information.
Usage is simple. After installing the Skill, you can trigger it with natural language instructions like "Generate AGENTS.md" or "Update the agents document." It automatically detects configuration files in the project such as Makefile, package.json, composer.json, and go.mod, extracting build commands, test commands, run commands, etc. It then generates a multi-layered AGENTS.md file containing global rules and subsystem scopes. You can further refine it with instructions like "Create an AGENTS.md for the subsystem."
It is ideal for teams or individuals who need to provide a unified project context for AI coding assistants (like Claude Code, Cursor, or GitHub Copilot). This is especially true for developers working with multi-language, multi-module projects (Go, PHP, TypeScript, Python, etc.) or teams wanting AI to better understand project structure, commands, and coding conventions.
It is recommended to use this tool uniformly during project initialization or refactoring. Note that it primarily relies on the agents.md specification. The generated root file is about 30 lines long, containing only priority rules and global defaults. More detailed subsystem rules are distributed to AGENTS.md files in respective subdirectories. Automatic command extraction requires the presence of corresponding configuration files (e.g., Makefile) in the project; otherwise, manual supplementation is needed.
Key Features
Compared to manually writing AGENTS.md, it not only automates generation but also supports incremental updates (idempotent operations), automatic subsystem detection and scope file generation, and command extraction from configuration files like Makefile/package.json. In contrast, Cursor's Rules generator lacks the ability to automatically parse cross-project configuration files.
Limitations
Requires the presence of configuration files like Makefile, package.json, composer.json, or go.mod in the project to automatically extract commands; otherwise, the generated AGENTS.md may be incomplete. It also depends on the agents.md specification version (currently 1.0).
FAQ
What's the difference between this Skill and the AGENTS.md specification?
AGENTS.md is a specification file format, while this Skill is a tool for generating and managing such files. It adheres to the agents.md specification and can automatically generate, update, and maintain AGENTS.md files.
How do I update an already generated AGENTS.md?
Simply instruct the AI with "Update AGENTS.md" or "Refresh the agents file." The Skill will update it in an idempotent manner, preserving the existing structure while refreshing the content and updating the timestamp in the file header.
