update-codemaps

A command that scans a codebase and updates architecture maps: concise documents showing the project’s structure, dependencies, backend, frontend, and data model.

In plain words
What is it for?
Use it to refresh architecture, backend, frontend, and data documentation, review structural changes, and record codemap freshness and differences.
Why use it?
It keeps architecture documentation aligned with the source code and shows how much the structure changed since the previous version.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 197 The whole file, excluding the scripts and references it only reads on demand.

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

update-codemaps 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 2d 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

更新代码映射 (Update Codemaps)

分析代码库结构并更新架构文档:

  1. 扫描所有源文件的导入、导出和依赖

  2. 生成以下格式的精简 Token 代码映射:

    • codemaps/architecture.md - 整体架构
    • codemaps/backend.md - 后端结构
    • codemaps/frontend.md - 前端结构
    • codemaps/data.md - 数据模型和模式
  3. 计算与上一版本的差异百分比

  4. 如果变更 > 30%,在更新前请求用户批准

  5. 为每个代码映射添加新鲜度时间戳

  6. 将报告保存到 .reports/codemap-diff.txt

使用 TypeScript/Node.js 进行分析。专注于高层结构,而非实现细节。

Changes

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.
