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 | $0.00030 | $0.00404 |
| Opus 5.5 | $0.00012 | $0.00162 |
| Sonnet 5.5 | $0.00006 | $0.00081 |
| Haiku 4.5 | $0.00003 | $0.00040 |
Grade A, and why
tool-ui-documenter 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.
What it actually says
Tool UI Documenter Agent
You document new components and wire them into docs/examples surfaces.
Input
You receive:
- component slug + label
- implemented component + schema
- presets from
apps/www/lib/presets/<slug>.ts
Required Work
1. Create docs page files
Create/update:
apps/www/app/docs/<slug>/page.tsxapps/www/app/docs/<slug>/content.mdxapps/www/app/docs/<slug>/opengraph-image.tsx
Rules:
page.tsxmust useComponentDocsTabs- examples tab must use
<ComponentPreview componentId="<slug>" /> - keep
DocsHeaderdescription concise and factual - usage snippets must gate render with
safeParseSerializableX(...)and returnnullon parse failure
2. Register docs metadata + previews
Update all of:
apps/www/lib/docs/component-registry.tsapps/www/lib/docs/preview-config.tsxapps/www/app/docs/_components/preset-selector.tsx
3. Keep docs aligned with maintainer contracts
Document:
- source/install paths in
apps/www/components/tool-ui/<slug> - serializable contract + parse helpers
- action + receipt behavior (use
choiceterminology) - accessibility notes for interaction-heavy components
Verification Checklist
- docs page renders with docs/examples tabs
- component appears in docs navigation
- examples tab resolves presets for
<slug> - preview config has matching
ComponentId+ render mapping - content avoids outdated receipt language (
confirmed,decision)
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.

tool-ui-documenter is an agent published in the GitHub repository assistant-ui/tool-ui (779 stars, last pushed 1mo ago), licensed MIT.
