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 | $0.00541 | $0.00541 |
| Opus 5 | $0.00270 | $0.00270 |
| Sonnet 5 | $0.00108 | $0.00108 |
| Haiku 4.5 | $0.00054 | $0.00054 |
Grade A, and why
happy-skills 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 5d 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
Happy Skills
用自然语言描述需求，自动生成设计文档并逐步实现代码。 把"想法→设计→代码→提交"的完整开发流程自动化。
Usage
1. Feature Development (Design → Execute)
# Step 1: 设计 - Q&A 对话生成设计文档
/feature-analyzer 用户登录功能，支持 OAuth2
# Step 2: 执行 - 按文档逐项实现
/feature-pipeline docs/features/user-login.md
2. Quick Development
/feature-dev 添加深色模式切换
3. Screenshot Analysis
/screenshot-analyzer ./app.png

Rules
- When updating skills, sync to both
README.md(中文) andREADME_EN.md(English) - Always update both README files together to keep them in sync
- Use AskUserQuestion for structured information gathering in skills
- Skills can be called directly:
/feature-dev,/feature-analyzer,/feature-pipeline,/screenshot-analyzer,/tts-skill,/video-producer,/issue-flow
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.
- 5d ago First seen · 59 lines · 541 tokens per session scan A cc271609fd75
happy-skills CLAUDE.md is an instructions file published in the GitHub repository notedit/happy-skills (340 stars, last pushed 6mo ago), licensed MIT. It adds 541 tokens to every session, about $0.0027 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.
