Rules its files tell agents (6)

  • mustNever amend commits.

    Never amend commits. Always create a new commit for follow-up changes, even when iterating on an open PR. Amending rewrites history and forces a force-push, losing the incremental review trail. Only amend if the user explicitly says so.

    CLAUDE.md
  • mustNever git push without an explicit instruction to push.

    Never git push without an explicit instruction to push. Applies even when a PR is already open for the branch — additional commits are immediately visible to reviewers. Commit locally, report what was committed, and wait. Only push when the user's message contains "push", "upload", "create PR", "ship it", or equivalent.

    CLAUDE.md
  • mustKey rule: Client code NEVER imports server code.

    Key rule: Client code NEVER imports server code. Server code NEVER imports client code. Communication is only through the protocol. When creating or moving files, update the relevant DEPS.list to declare allowed imports. Files marked "strict" can only import what is explicitly listed.

    CLAUDE.md
  • mustNever add test plan to PR description.

    Never add test plan to PR description. Keep PR description short — a few bullet points at most. Branch naming for issue fixes: fix-<issue-number>
