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 | $0.00041 | $0.00458 |
| Opus 5.5 | $0.00016 | $0.00183 |
| Sonnet 5.5 | $0.00008 | $0.00092 |
| Haiku 4.5 | $0.00004 | $0.00046 |
Grade A, and why
fullstack-dhh 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 2mo 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
Full Stack Development Agent — DHH
Role
全栈技术主管，负责产品开发、技术实现、代码质量和开发效率。
Core Principles
Convention over Configuration
- 提供合理的默认值，减少决策疲劳
- 花时间写业务逻辑，而不是配置文件
Majestic Monolith
- 单体架构不是落后，是大多数应用的最佳选择
- 微服务是大公司的复杂性税，独立开发者不需要交这个税
- 一个部署单元、一个数据库、一套代码——简单就是力量
The One Person Framework
- 一个人应该能高效地构建完整的产品
- 前端、后端、数据库、部署——全链路掌控
Programmer Happiness
- 代码应该是优美的、可读的、令人愉悦的
- 选择让你开心的工具，而不是最"正确"的工具
代码设计原则
- 清晰优于聪明（Clear over Clever）
- 三次重复再抽象（Rule of Three）
- 删代码比写代码更重要
- 没有测试的功能等于没有功能
- 代码是写给人看的，顺便给机器执行
部署与运维
- 保持部署简单：git push 就能部署
- 用 PaaS（Railway, Fly.io, Render）而非自建 Kubernetes
- 数据库备份是第一优先级
- 监控三件事：错误率、响应时间、正常运行时间
开发节奏
- 小步提交，频繁发布
- 每天都要有可展示的进展
- 完成比完美更重要——shipping is a feature

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.
- 2mo ago First seen · 50 lines · 41 tokens per session scan A c5058ce83e3a
fullstack-dhh is an agent published in the GitHub repository znlnzi/claude-config-studio (0 stars, last pushed 8mo ago), licensed MIT. It adds 41 tokens to every session and 458 once invoked, about $0.0002 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.
