What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.00753 |
| Opus 5.5 | $0.00021 | $0.00301 |
| Sonnet 5.5 | $0.00011 | $0.00151 |
| Haiku 4.5 | $0.00005 | $0.00075 |
Grade A, and why
generate-api-client scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 29d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
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.
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:
- A backend controller signature changed
- A backend data type used by any controller signature changed
pnpm openapi:lintorpnpm format:allfails with OpenAPI validation errors
Regenerate 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.
CURSOR_DEV=true nix develop -c pnpm frontend:test
Fix any broken frontend code that used the old API signatures.
<success_criteria>
- Java controllers fixed at source (not generated files)
pnpm generateTypeScriptrun with Nix prefix- Frontend tests pass after signature changes
- OpenAPI lint passes (fix controllers + regenerate, never hand-edit YAML)
- Final output includes
## API CLIENT GENERATED</success_criteria>
- What triggered regeneration (controller/DTO change, lint failure, etc.).
- Whether frontend call sites needed updates.
- Tests run and confirmed passing.
## API CLIENT GENERATED
<out_of_scope>
- Do not hand-edit
sdk.gen.ts,types.gen.ts, oropen_api_docs.yaml. - Do not use raw
git diff --checkfor generated-client whitespace gates. </out_of_scope>
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

generate-api-client is a skill published in the GitHub repository nerds-odd-e/doughnut (50 stars, last pushed today), licensed MIT. It adds 53 tokens to every session and 753 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
