Purpose: Keep packages/generated/donut-backend-api in sync with Java
controllers — never hand-edit generated output.
Output: Regenerated client + green frontend tests + summary ending with
## API CLIENT GENERATED.
</objective>
Never edit generated code directly. This includes whitespace-only cleanup in
sdk.gen.ts, types.gen.ts, and open_api_docs.yaml; if generated output
changes, accept it or fix the generator path.
Git does not use the Nix prefix. All other repo tooling does:
CURSOR_DEV=true nix develop -c …
Do not run raw git diff --check as a generated-client cleanup gate. Use
scripts/check_diff_whitespace.sh, which excludes generated API artifacts from
manual whitespace fixes.
Regenerate when:
pnpm openapi:lint or pnpm format:all fails with OpenAPI validation errorsRegenerate in the same change as the controller edit: the backend test
RobotsTests.openApiDocsMatchCommittedYaml fails until open_api_docs.yaml
matches, so a signature change cannot be committed on its own while CI stays green.
</context>
CURSOR_DEV=true nix develop -c pnpm frontend:test
Fix any broken frontend code that used the old API signatures. </step>
<step name="openapi_lint_failures"> If `pnpm openapi:lint` fails: **do not** edit `open_api_docs.yaml` (it is generated). Fix Java controllers, regenerate, then re-lint. Playbook details: `.agents/skills/linting_formating/SKILL.md` → **OpenAPI Linting**. </step> </process><success_criteria>
