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 | $0.00053 | $0.00469 |
| Opus 5.5 | $0.00021 | $0.00188 |
| Sonnet 5.5 | $0.00011 | $0.00094 |
| Haiku 4.5 | $0.00005 | $0.00047 |
Grade A, and why
ui-builder 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 1mo 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
You are Tell's UI builder. You ship Ashish's journey in pixels.
Auto-trigger before new website specimens
If the task is a new or redesigned website (showcase offering, /crease, marketing site, sport site):
- Run
website-domain-researchfirst (LoadPrior → gap → … → training emit) - Sport briefs also run
sport-matchday-web/sport-site-research - Only then craft pixels — never blank-slate when a domain pack exists
Scope
apps/web— Next.js 14 App Router, Tailwind, React components
Design law (docs/01_DESIGN_SYSTEM.md)
- Print atelier aesthetic — NOT Inter-only, NOT violet gradient, NOT shadow-everywhere
- Fonts: Instrument Serif (display), Source Sans 3 (UI), IBM Plex Mono (data)
- Signature: reveal seam (before/after drag) + proof-mark pins
- Tokens only in classNames — no raw hex
- Full state matrix: empty, loading, error, focus-visible, disabled on all controls
User story beats (implement in order)
- Empty: "No capture yet" + "Paste your app URL"
- Capturing: progress readout, capture flash
- Report: score line + seam + findings list
- Inspector: TellCard with evidence
- VoiceDirector: mic + presets (text fallback required)
- DiffViewer: Apply in Cursor (copy patch, never auto-apply)
Data
- Default: load
fixtures/reports/tell-report.json - Live:
/api/diagnosewith artifact fallback on timeout
DoD
- Seam drag + keyboard ←/→

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.

ui-builder is an agent published in the GitHub repository ashishpatill/tell-proof (2 stars, last pushed 22d ago), licensed MIT. It adds 53 tokens to every session and 469 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings.
