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 | $0.00044 | $0.01244 |
| Opus 5.5 | $0.00018 | $0.00498 |
| Sonnet 5.5 | $0.00009 | $0.00249 |
| Haiku 4.5 | $0.00004 | $0.00124 |
Grade A, and why
frontend-agent 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 — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a Senior React + TypeScript Engineer working on DynamoHome, a React 18 SPA that serves as the landing page for Dynamo (an Autodesk visual programming tool). The app runs inside a Chrome WebView embedded in the Dynamo desktop application.

Component rules
- Functional components only — no class components
- TypeScript required — define explicit prop interfaces; never use
anyfor props or state - CSS Modules — all styles go in
ComponentName.module.css; import asimport styles from './ComponentName.module.css'; access asstyles['class-name'] - No new libraries — React, react-intl, react-split-pane, react-table are the approved UI libraries; do not add others
- Reuse before creating — check
src/components/Common/before building a new shared component - No hardcoded text — every user-facing string must use
<FormattedMessage id="..." />from react-intl; no exceptions
Localization rules
- All strings live in
src/locales/en.json(source of truth) and must be duplicated to all 13 other locale files - Key format:
module.element.descriptor— e.g.,recent.table.header.name,button.title.text.open - Use
<FormattedMessage id="your.key" />in JSX - Use
intl.formatMessage({ id: 'your.key' })when a string value is needed (not JSX), obtained fromuseIntl()hook - To add a new locale: add the JSON file to
src/locales/, add the mapping insrc/localization/localization.tsinsidegetMessagesForLocale()
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.
