dotfiles: Instructions file for Claude Code

CLAUDE.md

dotfiles CLAUDE.md is an instructions file for Claude Code from magic3007/dotfiles. It costs 3,023 tokens per session, scanned A, original, MIT.

Repository-specific instructions for a dotfiles repository, which stores personal computer settings such as shell, Git, and editor configuration and installs them with Dotbot.

In plain words
What is it for?
Use it when installing or previewing configuration links, synchronizing dotfiles, updating Vim submodules, or working on the repository's package and tool setup.
Why use it?
They describe the two-phase installation process, dry-run option, synchronization commands, and a rule not to change fish-shell files.

Instructions file for Claude Code

Written for Claude Code: ${CLAUDE_SKILL_DIR} variable. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is magic3007/dotfiles's own configuration. It tells Claude Code how to work on dotfiles 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 dotfiles 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

dotfiles 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 yesterday.

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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Overview

Dotfiles repository using Dotbot for installation. Stores configuration files and symlinks them to their standard locations (~/.zshrc, ~/.gitconfig, ~/.config/nvim, etc.).

Commands

./install              # Full installation (idempotent, safe to re-run)
./install -n           # Dry run — preview what would be installed
./sync.sh              # Quick sync (git pull + cross-platform symlinks only)
./sync.sh --install    # Install auto-sync scheduler (every 15 minutes)
git submodule update --init --recursive  # Update Vim plugins

⚠️ 重要约束

  • 禁止更新 fish 相关配置（已 archive）。 fish 配置已从 fish/ 移到 archive/fish/，处于冻结状态。不要修改 archive/fish/ 下的任何文件，也不要在 install.conf.yaml 中新增 fish 相关的 symlink 或安装步骤。现有 ~/.config/fish symlink 保留是为了让还在用 fish 的登录不丢配置，不要删除。详见 archive/fish/README.md。

Architecture

Two-Phase Installation (install.conf.yaml)

  • Phase 1 — Local: Defaults, directory creation, submodules, backup existing configs, symlinks. No network required, always succeeds.
  • Phase 2 — Network: Homebrew, platform packages, oh-my-zsh + plugins, fzf, Node.js/nvm, GitHub CLI, AI coding tools. All commands use --connect-timeout / || true to avoid blocking without network.

Symlink Model

All configs live in this repo and are symlinked to ~ via Dotbot. The link section in install.conf.yaml is the single source of truth for what gets symlinked where. When adding new configs: add files to the repo, then add symlink entries to install.conf.yaml.

Auto-Sync System

sync.sh provides automatic 15-minute cross-platform sync across all machines (macOS, Linux):

  • ./sync.sh — Git pull + apply only cross-platform symlinks (via sync.conf.yaml)
  • ./sync.sh --install — Install scheduler: macOS LaunchAgent or Linux systemd timer
  • Auto-enabled — sync.sh --install runs automatically during ./install, no manual setup needed
  • Error notification — On failure, sends alert via wechat-reminder (Feishu/WeChat)

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.
