Devin supports AGENTS.md - a simple, open standard for providing context and instructions to AI agents. Think of AGENTS.md as a README for agents.

Creating an AGENTS.md File

Just put an AGENTS.md file in your project root (or anywhere else). Devin will look for the file before it starts coding. Devin automatically includes up to 16 KiB (16,384 bytes) from the beginning of each AGENTS.md file in its context. For longer files, Devin receives a truncation notice and can read the full file on demand, but instructions after the limit are not included automatically. Keep critical instructions near the top, keep always-on guidance under 16 KiB, and move longer or situational guidance into skills or referenced files. Here’s an example:
We also highly recommend doing repo setup to give Devin context on how to work with your repository.
