Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.03675 |
| Opus 5 | $0.00000 | $0.01837 |
| Sonnet 5 | $0.00000 | $0.00735 |
| Haiku 4.5 | $0.00000 | $0.00367 |
Grade A, and why
cli 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
donut-cli
TypeScript CLI for Donut. Lives in cli/.
Structure

src/commonUIComponents/ # Context-neutral Ink UI reused across stages and the main prompt (borders, guidance lists, y/n, past user block, stage key context)
src/sessionScrollback/ # One Ink `<Static>` session history above the live column; transcript factories + recall answered rows; append context for stages

TypeScript module exports
Keep each module’s public surface small: export only what other modules actually use. Prefer leaving helpers, constants, and types unexported when they are implementation details. Do not add exports “for tests” or “maybe later” — if only tests need a symbol, test through a stable-boundary entry point when possible (unit-testing.mdc; see Vitest: observable behavior below). Avoid widening the export list when a single import site could instead live next to the code.
Commands
| Task | Command |
|---|---|
| Build bundle | pnpm cli:bundle |
| Run tests | pnpm cli:test |
| Mutation test (Stryker) | CURSOR_DEV=true nix develop -c bash -c 'cd cli && pnpm test:mutation' — see the mutation-testing skill |
| Format | pnpm cli:format |
| Lint | pnpm cli:lint |
Architecture notes
CLI architecture guidance lives in this rule and in cli/ code layout. New planning artifacts go under .planning/phases/ or .planning/quick/ — see gsd-coexistence.mdc.
Apply architectural changes when a feature needs them; challenge the fit first.
Session scrollback (interactive) — Past session lines use one Ink <Static> (append-only) above the live column (stage + MainInteractivePrompt). Generic SessionScrollback stays domain-agnostic; shell transcript shapes live in interactiveCliTranscript.tsx; recall “answered” outcomes use recallAnsweredScrollback.tsx; stages append via sessionScrollbackAppendContext.
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.

cli is a cursor rule published in the GitHub repository nerds-odd-e/doughnut (49 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,675 tokens. 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.
