Bklit UI is an open-source collection of customizable interface components and charts for building React applications with shadcn. Developers use it to add data visualizations such as funnels, gauges, maps, financial charts, and other interactive displays. The catalogue add-ons provide workflows for using its components and chart registry.

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 | $0.00741 | $0.00741 |
| Opus 5.5 | $0.00296 | $0.00296 |
| Sonnet 5.5 | $0.00148 | $0.00148 |
| Haiku 4.5 | $0.00074 | $0.00074 |
Grade A, and why
bklit-ui 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 14d 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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent guide (bklit-ui contributors)
This repo uses Agent Skills in .agents/skills/ for monorepo-specific workflows. Read the relevant skill before acting — do not guess at file layout.
Building or editing a chart
Always read and follow .agents/skills/bklit-studio/SKILL.md first.
Develop and preview charts in Studio at http://localhost:3000/studio (pnpm dev from repo root). Use ?chart=<slug> for a specific chart (slugs in packages/studio/src/chart-slugs.ts).
The local /playground route is deprecated (redirects to Studio). Do not scaffold apps/web/app/playground/ or apps/web/components/playground/ for new work.
Committed building blocks (do not reimplement):
| Area | Path |
|---|---|
| Studio app shell | apps/web/app/studio/page.tsx → @bklitui/studio StudioShell |
| Chart registry + preview render | packages/studio/src/lib/registry.tsx |
| Layer tree (components panel) | packages/studio/src/lib/studio-components.ts |
| Control groups | packages/studio/src/lib/registry-control-groups.ts |
| URL state | packages/studio/src/lib/studio-parsers.ts |
| Chart primitives | packages/ui/src/charts/ |
Pane rules: left = layers + data + motion; right = selected layer properties; visibility = layer eye toggles.
Shipping a chart to production
Read .agents/skills/bklit-ship/SKILL.md when the chart API is stable in packages/ui and Studio.

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.
