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 | $0.01067 | $0.01067 |
| Opus 5.5 | $0.00427 | $0.00427 |
| Sonnet 5.5 | $0.00213 | $0.00213 |
| Haiku 4.5 | $0.00107 | $0.00107 |
Grade A, and why
tingly-box CLAUDE.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 12d 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tingly-Box
An Intelligence Orchestrator including LLM gateway, remote control and guard rails.
Guideline
UX-First (highest priority)
Tingly-Box is a technical product, but the product itself is the core — UX always comes first. Technology has to be implemented sensibly, and sometimes it must yield. When UX conflicts with implementation convenience, the direction of compromise is always to push UX further, not to dilute it.
Before building a new feature or changing an existing one, read .design/ux-principles.md. It distills 12 judgment criteria from real work (organize information architecture around user questions; eliminate mode pickers; split name collisions; separate orthogonal axes; show concrete values instead of aliases; smart defaults over toggles; diagnostics must traverse the real path; embed education in the product; reduce visual noise; "done" ≠ locked; surface the artifact for the next action; scope side effects to the current surface), and includes a checklist usable directly in PR review.
New feature design and PR review should be explicitly checked against these principles; deviations require a clear justification.
Frontend
API related code is generated by swagger. For each new feature, use a placeholder function for api (if not support for current version).
- use
MUIfor new frontend component. - take care of
layoutwhile add new pages. - The theme, icons and page primitives (
PageLayout,PageHeader,Surface,EmptyState,DialogHeader,ConfirmDialog,CopyIconButton) live infrontend/packages/ui(@tingly/ui), shared with the embedded Projects pages. Change them there; the oldsrc/paths only re-export.
Icons
General UI icons come from @/components/icons (Tabler icons adapted to MUI via tablerMui()). Do not import @mui/icons-material directly.
- Prefer the predefined, MUI-named icons:
import { Close, Add, Delete, Search } from '@/components/icons'(same API as MUI —fontSize/colorsemantic colors all work). - When one isn't predefined, use the generic factory:
const Foo = tablerMui(IconFoo)(IconFoofrom@tabler/icons-react), and add it toindex.tsxif it's worth reusing. - Brand / provider logos still go through
BrandIcons.tsx/ProviderIcon.tsx(Lobehub + custom SVG). - See
.design/icon-hierarchy.mdfor details.
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.
