01 / Generated file guards
Explain why manual changesets are banned
The guide says a GitHub Action creates changesets from the PR title. A manually authored changeset takes precedence, which is why the instruction prohibits adding one rather than merely calling it unnecessary.
Source excerpt starting at line 39.397. **Don't write changeset files.** A GitHub Action adds `.changeset/*.md` to your branch from the PR title, so a good title is all that's needed. The bot leaves an existing changeset alone, so a hand-written one silently replaces your title in the changelog.
02 / Contribution etiquette
Check for overlapping work before proposing a patch
The agentic contribution policy distinguishes duplicate fixes from materially different approaches. A second approach requires an explanation in the issue rather than an unexplained competing PR.
Source excerpt starting at line 58.58- If your approach is materially different, explain the difference and why a second PR is needed in the issue thread.
03 / Contribution etiquette
Define what disclosure covers
Disclosure applies to non-trivial AI assistance in both code and the PR description. The rule also distinguishes trivial autocomplete and requires self-review of generated code.
Source excerpt starting at line 29.293. **AI disclosure is mandatory.** If AI was used in any non-trivial way (drafting code, writing the PR description, etc.), you must disclose this in the PR template. Trivial autocomplete does not need to be disclosed. All AI-generated code must be self-reviewed.
04 / Behavioral framing
Assign review responsibility to the submitting human
The policy requires a human who understands and can defend the change. It makes reviewing every changed line and running relevant tests part of that responsibility.
Source excerpt starting at line 68.68- The submitting human is responsible for reviewing every changed line and running relevant tests.
