One file defines separate rules for maintainers, external contributors, and forks, then explains how the agent identifies its role.
Explain how to identify the contributor’s role before listing its permissions. Use the most restricted role when identity or access cannot be verified.
The agent chooses a scope before using the file. Maintainer status requires a listed username, the canonical remote, and verified write access; otherwise the most restricted scope applies.
AGENTS.mdL12–17
Source excerpt starting at line 12.
12- Maintainer accounts are listed in `.github/MAINTAINERS`. Treat the acting13 account as a verified maintainer only when its username is listed there, the14 configured remote is the canonical `herdrdev/herdr` repository, and the15 authenticated account has write access to that repository. If any condition16 cannot be verified, skip maintainer workflow and follow the external17 contributor guardrail instead.
Distinguish contributor roles before public actions
The pull-request section distinguishes branches owned by Vercel from external forks. It assigns different authorship permissions to those cases and points to the repository’s pull-request template.

Refer to the guidelines in `.github/pull_request_template.md`.314While you cannot write the full description for the user, you may offer to help review the description, or provide helpful technical details. You can provide them a link to the GitHub URL to create the PR.
A separate rule asks external contributors to create a named disclosure file with prescribed text. The condition is the contributor’s relationship to the repository, rather than the kind of code change.
