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 | $0.00556 | $0.00556 |
| Opus 5.5 | $0.00222 | $0.00222 |
| Sonnet 5.5 | $0.00111 | $0.00111 |
| Haiku 4.5 | $0.00056 | $0.00056 |
Grade A, and why
builder-design 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 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.

builder-design — AI UI Design Skills Pack v1.0.0
What This Pack Is
8 skills and 5 agents that enforce design quality for AI feature UIs. Every skill has a Completion Statement Format — a literal code block that must be filled with real values before work is considered done.
Skills
| Skill | Trigger |
|---|---|
ai-states-required |
Before any AI feature component code is written |
design-before-code |
Before any component implementation begins |
accessible-ai-output |
Before any AI output rendering ships |
ai-component-patterns |
When implementing any of the 6 AI-native components |
prompt-ux-design |
Before designing any AI prompt input |
ai-output-design |
When designing AI response rendering |
ai-onboarding-design |
When designing first-run or empty state for an AI feature |
design-token-audit |
Before merging any AI feature UI component |
Agents
| Agent | Model | Use When |
|---|---|---|
ai-ui-designer |
Opus | Designing a new AI component from scratch |
ux-critic |
Sonnet | Reviewing any AI feature UI before ship |
state-designer |
Sonnet | Mapping states for a new AI feature |
prompt-ux-designer |
Sonnet | Designing the prompt input experience |
accessibility-reviewer |
Sonnet | Accessibility audit before ship |
Enforcement Model
Every skill's Completion Statement Format must be filled with real values:
- Real component names
- Real file paths
- Real counts (not "all states designed" — "7/7 states designed")
- Real verdicts (PASS / BLOCK — not "looks good")
File Conventions
- State maps:
design/ai-states/<feature>.md - Component specs:
design/specs/<feature>.md - Prompt UX specs:
design/specs/<feature>-prompt-ux.md - UX critiques:
design/reviews/<feature>/<date>-ux-critique.md - Accessibility reviews:
design/reviews/<feature>/<date>-accessibility.md
Quality Bar
A component is not complete until:
- Spec exists at
design/specs/<feature>.md - State map exists at
design/ai-states/<feature>.md - All AI-native component patterns satisfied
- Zero hardcoded values (design-token-audit passes)
- Accessibility review: no BLOCK issues
- UX critique: no BLOCK issues
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.

builder-design CLAUDE.md is an instructions file published in the GitHub repository RBraga01/builder-design (2 stars, last pushed 8d ago), licensed MIT. It adds 556 tokens to every session, about $0.0022 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 2026-08-31.
