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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00047 | $0.01246 |
| Opus 5.5 | $0.00019 | $0.00498 |
| Sonnet 5.5 | $0.00009 | $0.00249 |
| Haiku 4.5 | $0.00005 | $0.00125 |
Grade A, and why
bklit-studio 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 21d 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 — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Bklit Studio Skill (chart development)
Monorepo contributors only. Use this skill automatically whenever you build, edit, or prototype a chart — before shipping via bklit-ship.
Studio at /studio is the single development surface: full editor shell, component tree, properties, motion, codegen, and registry previews. Do not scaffold apps/web/app/playground/.
When to use (auto-trigger)
- Build, prototype, or edit a chart (new or existing)
- Tune props, layers, data, styling, or animation
- Mentions Studio,
/studio, registry preview, or chart controls - Work continues from a prior playground task → use Studio instead
Quick start
pnpm dev # repo root
Open http://localhost:3000/studio (optional query: ?chart=line-chart).
| Task | URL |
|---|---|
| Edit existing chart | /studio?chart=<slug> — slugs in packages/studio/src/chart-slugs.ts |
| Profit/loss line mode | /studio?chart=line-chart&lineChartMode=profitLoss |
Editor layout
| Region | Purpose |
|---|---|
| Left | Chart type (in full Studio), layer list, data controls, animation |
| Center | Canvas, rulers, resizable frame, replay/scramble |
| Right | Properties for the selected layer |
Pane rules: animation → left (motionPanel on chart config); per-layer props → right; visibility → eye icon on layer (uses hiddenComponents in URL state).
Where to implement (existing charts)
Edit the chart in packages/studio and packages/ui — not apps/web/components/playground/.
| Concern | Path |
|---|---|
| Chart preview + codegen | packages/studio/src/lib/registry.tsx (render, generateCode) |
| Layer tree (components panel) | packages/studio/src/lib/studio-components.ts (resolve*Components) |
| Control groups (properties) | packages/studio/src/lib/registry-control-groups.ts |
| URL / default state | packages/studio/src/lib/studio-parsers.ts |
| Chart UI | packages/ui/src/charts/ |
| Slugs | packages/studio/src/chart-slugs.ts + studioRegistry in registry.tsx |
| Studio-only previews | packages/studio/src/components/charts/*-studio-preview.tsx |
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.

bklit-studio is a skill published in the GitHub repository bklit/bklit-ui (1,898 stars, last pushed 5d ago), licensed MIT. It adds 47 tokens to every session and 1,246 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
