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 | $0.01299 | $0.01299 |
| Opus 5.5 | $0.00520 | $0.00520 |
| Sonnet 5.5 | $0.00260 | $0.00260 |
| Haiku 4.5 | $0.00130 | $0.00130 |
Grade A, and why
design-system AGENTS.md 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 2mo 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Iress Design System (IDS) monorepo — React component library and design tokens for Iress products.
Setup
corepack enable
yarn
yarn prepare # installs husky hooks and builds all packages
Node 22, Yarn 4 (Berry). The packageManager field in package.json pins the exact Yarn version; corepack enable is required to activate it.
⚠️ Long-running commands — never run in agent workflows
Any dev, test (without :coverage), or watch command starts a persistent process that never exits. Always use these non-blocking alternatives:
| Instead of | Use |
|---|---|
yarn dev / yarn storybook |
yarn build (one-shot build) |
yarn workspace ... run test |
yarn workspace ... run test:coverage (runs once and exits) |
Build
yarn build # builds all packages (topological order) then runs translate scripts
The yarn monorepo alias runs yarn workspaces foreach -Ai --topological-dev --exclude=@iress/design-system-monorepo. Use it for cross-package commands.
Testing
yarn test:coverage # all packages, with coverage
yarn test:ci # coverage + threshold check
# single package
yarn workspace @iress-oss/ids-components run test:coverage
# single file
yarn workspace @iress-oss/ids-components run test:coverage Button.test.tsx
Tests use Vitest. Test startup can take 30+ seconds — this is normal, not a failure. Wait for explicit PASS/FAIL output.
Test files must live inside each package's src/ directory. Do not create tests for pure interface/type files with no runtime behavior.
Type checking
yarn typecheck # all packages
Bundle size
yarn size # check all packages against budgets
yarn size:check # same, but JSON output (useful for scripting)
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.
