trace: Instructions file for Claude Code

CLAUDE.md

trace CLAUDE.md is an instructions file for Claude Code from BUKOWSKIREAL/trace. It costs 560 tokens per session, scanned A, original, MIT.

Repository instructions for Trace, a Python application that tracks file versions across cooperating command-line agents. It uses SQLite for storage, watchdog to monitor files, and Textual for its terminal interface.

In plain words
What is it for?
Use it when changing Trace's file watcher, version repository, batching, handlers, command-line interface, or MCP server, and when running its tests and demos.
Why use it?
It records the project's commands, file-handling rules, excluded runtime directories, and required tests. This reduces the risk of reintroducing removed components or skipping verification after sensitive changes.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions Codex.

This is BUKOWSKIREAL/trace's own configuration. It tells Claude Code how to work on trace itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything trace configures →

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

trace 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 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

CLAUDE.md

本项目是 Trace,一个 Python + SQLite + watchdog + Textual 的多 CLI Agent 协作版本追踪器。

常用命令

uv sync
uv run python -m unittest discover -s tests
uv run python code/main.py --workspace test_workspace
uv run python code/main.py --workspace test_workspace --headless
uv run python code/main.py --choose
bash scripts/demo.sh

TUI 操作台:

uv run python code/main.py --workspace test_workspace

MCP 服务器测试:

python run_mcp_server.py --workspace test_workspace
uv run python -m unittest tests.test_trace_mcp_server

项目约定

  • Python 依赖通过 uv 管理,不要手动创建新的 venv 方案。
  • Phase 6 后 Trace 是纯 Python / Textual TUI 产品;不要重新引入旧桌面前端、系统托盘或平台打包链。
  • test_workspace/ 是本地演示目录,不进入版本控制。
  • .trace/ 是运行时仓库目录,不进入版本控制。
  • dist/ 和 build/ 是本地构建产物目录,不进入版本控制。
  • 文件版本存储以字节 blob 为准,handler 只负责 UI diff 展示。
  • .docx/.pptx/.xlsx/.pdf/image 等格式有专门 handler;未知格式走 BinaryHandler。
  • 修改 watcher、repository、batcher 时要跑完整测试。

MCP 功能

  • MCP 服务器位于 code/mcp/trace_server.py,提供 trace_record_files 工具。
  • 项目根目录的 .mcp.json 为 Claude Code CLI 提供配置。
  • run_mcp_server.py 是通用的 Python 包装脚本,自动设置 PYTHONPATH。
  • scripts/start_mcp_server.sh 是 Bash 启动脚本。
  • MCP 配置详见 MCP_SETUP.md。
  • 修改 MCP 相关代码后必须运行 tests/test_trace_mcp_server.py 验证。

验证重点

  • Repository.commit() 必须保持全量 manifest 语义。
  • checkout_commit() 必须删除目标 manifest 中不存在的已跟踪文件。
  • watcher 删除事件必须走 kind="delete",不能被 modify 事件去重吞掉。
  • 多 agent 防抖必须保持每个 agent 独立 timer。
  • MCP 服务器必须能在不同 agent 环境(Claude、Codex、Cursor 等)中正常运行。
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.
