Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

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 12d 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

CLAUDE.md / 项目记忆整理

用户输入

$ARGUMENTS

支持的意图:

  • create
  • update
  • audit
  • 指定某个路径下的 CLAUDE.md

核心原则

  • CLAUDE.md 是 Claude Code 自动加载的长期项目上下文
  • 内容要短、准、长期有效
  • 不要把 lint / format 规则硬塞进去
  • 不要把一次性任务说明塞进去
  • 不要自动生成一堆无价值内容
  • AGENTS.md 不会被 Claude Code 自动读取;需要共享时从 CLAUDE.md 导入 @AGENTS.md 或使用 symlink
  • subagent 定义属于 .claude/agents/,不要把 AGENTS.md 当成 agent 配置

推荐结构

  • Project Overview
  • Tech Stack
  • Project Structure
  • Development Commands
  • Critical Conventions
  • Known Issues / Gotchas

执行流程

create(创建)

  1. 分析项目结构和技术栈
  2. 草拟 CLAUDE.md
  3. 给用户审阅
  4. 确认后写入

update(更新)

  1. 读取现有 CLAUDE.md
  2. 找出冗余、过时或不该存在的内容
  3. 给出优化建议
  4. 审阅后更新

audit(审计)

  1. 检查行数和结构
  2. 识别 anti-patterns
  3. 输出报告,不直接改文件

质量约束

  • 目标控制在 200 行以内;更长内容拆到按路径生效的 rules 或按需 skills
  • 面向所有会话都适用
  • 文件引用可以减少重复维护,但不会减少加载上下文;需要按需加载时使用 rules 或 skills
  • 命令必须真实可用

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.
