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 | $0.00070 | $0.00368 |
| Opus 5 | $0.00035 | $0.00184 |
| Sonnet 5 | $0.00014 | $0.00074 |
| Haiku 4.5 | $0.00007 | $0.00037 |
Grade A, and why
shadcn-usage 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 9d 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
shadcn Usage
Use this skill for dashboard UI and design-system work.
Design contract
Read DESIGN.md before changing interface behavior, visual hierarchy, product language, or layout. Keep UI decisions aligned with the existing shadcn/Tailwind style instead of inventing a parallel component system.
The dashboard should feel like a professional market-monitoring console:
- clear status and source labels;
- compact cards and tables;
- readable charts;
- calm alert language;
- honest loading, empty, stale, and error states;
- responsive behavior across mobile, tablet, laptop, and desktop.
Components
Use existing shadcn primitives and local UI components before adding new abstractions. Keep Client Components focused on interaction and rendering; keep provider and credential logic on the server.
Do not reintroduce removed portfolio UI unless the specification changes.
Copy and tone
Use user-facing language that is professional and product-like. Avoid comments or UI copy that sound like an agent speaking privately to the developer.
Generated analysis must remain informational. Use labels such as "AI brief", "notable movement", "source", "last updated", and "demo quota" honestly.
States and accessibility
For any new UI surface, define:
- loading state;
- empty state;
- error or partial-failure state;
- keyboard and screen-reader behavior where interactive;
- responsive layout behavior.
Use Playwright coverage for meaningful viewport or interaction changes.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

shadcn-usage is a skill published in the GitHub repository dcosodev/market-inspector (0 stars, last pushed 12d ago), licensed MIT. It adds 70 tokens to every session and 368 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
