# Prepare PR This is a high-trust workflow. Surface any destructive or ambiguous step before proceeding. Workflow: 1. Group current changes into logical commits, ideally by done-plan. 2. Create focused commits without staging unrelated work. 3. Fetch and rebase onto `origin/main`. 4. Resolve obvious conflicts directly. Ask the user about semantic conflicts. 5. Run the relevant build steps and fix straightforward failures. 6. Create or update the PR with a summary built from the plans and current diff. 7. Push with `--force-with-lease` only when rebase made it necessary. Rules: - Never use blanket staging. - Treat secrets and credentials as stop conditions. - Keep build-fix commits separate when they are distinct from the feature work. - If GitHub CLI or network access is unavailable, report exactly where the flow stopped.
