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 | $0.00198 | $0.04098 |
| Opus 5 | $0.00099 | $0.02049 |
| Sonnet 5 | $0.00040 | $0.00820 |
| Haiku 4.5 | $0.00020 | $0.00410 |
Grade A, and why
tailwind-v4-shadcn 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 11d 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.

⚠️ BEFORE YOU START (READ THIS!)
CRITICAL FOR AI AGENTS: If you're Claude Code helping a user set up Tailwind v4:
- Explicitly state you're using this skill at the start of the conversation
- Reference patterns from the skill rather than general knowledge
- Prevent known issues listed in
reference/common-gotchas.md - Don't guess - if unsure, check the skill documentation
USER ACTION REQUIRED: Tell Claude to check this skill first!
Say: "I'm setting up Tailwind v4 + shadcn/ui - check the tailwind-v4-shadcn skill first"
Why This Matters (Real-World Results)
Without skill activation:
- ❌ Setup time: ~5 minutes
- ❌ Errors encountered: 2-3 (tw-animate-css, duplicate @layer base)
- ❌ Manual fixes needed: 2+ commits
- ❌ Token usage: ~65k
- ❌ User confidence: Required debugging
With skill activation:
- ✅ Setup time: ~1 minute
- ✅ Errors encountered: 0
- ✅ Manual fixes needed: 0
- ✅ Token usage: ~20k (70% reduction)
- ✅ User confidence: Instant success
Known Issues This Skill Prevents
- tw-animate-css import error (deprecated in v4)
- Duplicate @layer base blocks (shadcn init adds its own)
- Wrong template selection (vanilla TS vs React)
- Missing post-init cleanup (incompatible CSS rules)
- Wrong plugin syntax (using @import or require() instead of @plugin directive)

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.

tailwind-v4-shadcn is a skill published in the GitHub repository NikitaDmitrieff/auto-co-meta (43 stars, last pushed 2mo ago), licensed MIT. It adds 198 tokens to every session and 4,098 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings.
