 # Agent instructions
 
-Only when you are using Kit as your agent harness: if you notice an issue with Kit's harness that produces friction, document it in `docs/issues/<issue-name>.md`. Do not use this self-reporting mechanism for issues with other harnesses.
+Only when you are using Kit as your agent harness: report issues with Kit's harness at https://github.com/speakeasy-api/kit/issues. Do not report issues with other harnesses there. Do not open an issue on the user's behalf unless the user explicitly requests it; ask the user first when they have not already made that request. Follow [Reporting Kit Issues](docs/user/reporting-kit-issues.md).
 
 Changes that meaningfully affect Kit's behavior must be accompanied by a version bump. Before 1.0, features and fixes receive a patch version bump; larger changes and refactors receive a minor version bump, but confirm the minor bump with a human first.
