Automating Project Documentation for AI Coding Agents
The author created a command that generates project documentation for AI coding agents like Cursor and Claude Code, helping them quickly orient themselves at the start of each session.
Why it matters
This approach helps improve the workflow and productivity of AI coding agents by providing them with the necessary context upfront, reducing the time spent on re-orienting at the start of each session.
Key Points
- 1Generates AGENTS.md file with project overview, tech stack, folder structure, and known issues
- 2Creates short README.md files in folders to aid navigation
- 3Prioritizes accurate and concise information over comprehensive documentation
- 4Can be run during breaks to keep documentation up-to-date
Details
The author found that repeatedly explaining project context to AI coding agents was slowing down their workflow. To address this, they created a command that automatically generates and updates project documentation. The command reads a markdown prompt file, walks the entire repository, and produces two key outputs: an AGENTS.md file at the root with a machine-oriented map of the project, and short README.md files in relevant folders to aid navigation. The AGENTS.md file includes the project's one-line purpose, tech stack, folder structure, and known issues or 'footguns'. The author designed the documentation to be accurate and scannable, rather than comprehensive and stale. By running this command during breaks, the author can keep the project documentation up-to-date, allowing AI agents to quickly orient themselves at the start of each session without repeated explanations.
