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 | $0.00510 | $0.00510 |
| Opus 5 | $0.00255 | $0.00255 |
| Sonnet 5 | $0.00102 | $0.00102 |
| Haiku 4.5 | $0.00051 | $0.00051 |
Grade A, and why
larksnap 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 10d 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
基本约定
- 输出都用中文，禁止使用任何互联网黑话（规约、派生、等），所有解释必须用大白话，代码必须简洁易懂。
- 写长文件的时候，不要一次写完，分批写到文件里面，不然会api中断，什么都写不进去浪费token
Plan 文件管理
- plan 文件不要写到 ~/.claude/plans/ 这里面，无法跟随项目管理
- INPORTANT 所有计划都需要写到 docs/plans/ 目录下，经过人工审查修改后再确认编码
- 所有正式计划文档都得写到这里面，跟随项目而走：docs/plans/（语义化命名，添加精确日期前缀，提交到 git）
- 命名格式：YYYY-MM-DD-功能描述.md（如：2026-02-03-ES集成.md）
- 完成计划后，立即将重要内容整理到 docs/plans/ 目录
开发规范
【代码生成原则（按优先级）】
- First Principles（第一性原理）：梳理最核心需求与边界
- YAGNI：只实现当前真正需要的功能
- KISS：保持设计和实现的简单性
- SOLID：面向对象/模块化设计时，遵循单一职责、开放封闭等
- DRY：消除重复，提炼公用逻辑
- 注意：你写的代码和文档后续会被codex和gemini进行审查
根据场景动态调整顺序
- 架构级／需求分析（Project Kickoff） First Principles → YAGNI → KISS → SOLID → DRY
- 新功能迭代／增量开发：YAGNI → KISS → SOLID → DRY → First Principles
- 小函数／工具库实现：KISS → DRY → YAGNI → SOLID → First Principles
- 复杂业务组件／面向对象建模：First Principles → SOLID → YAGNI → KISS → DRY
文档写入
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.
- 10d ago First seen · 29 lines · 510 tokens per session scan A 127a4f05f669
larksnap CLAUDE.md is an instructions file published in the GitHub repository AmbroseX/larksnap (269 stars, last pushed yesterday), licensed Apache-2.0. It adds 510 tokens to every session, about $0.0026 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 2026-08-30.
