dotfiles: Instructions file for Claude Code

CLAUDE.md

dotfiles CLAUDE.md is an instructions file for Claude Code from IvanWng97/dotfiles. It costs 199 tokens per session, scanned B, original, MIT.

Project-specific instructions for a macOS configuration repository, often called dotfiles, that manages settings for tools such as Neovim, Zsh, Tmux, and Homebrew. They explain how to edit, check, back up, and install those settings safely.

In plain words
What is it for?
Guiding changes to the dotfiles repository, checking script and symlink health with make doctor, and handling backups, Homebrew packages, and Claude Code settings.
Why use it?
They prevent common mistakes, such as treating Zsh scripts as Bash or overwriting Claude Code's own settings file.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions Claude Code.

This is IvanWng97/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 B, and why

dotfiles CLAUDE.md scanned grade B with 1 finding 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- `~/.claude/settings.json` is deliberately **not stowed** (Claude Code rewrites it in place, replacing symlinks). Sync it via `make backup` → `Backup/claude-settings.json`; `make install` seeds it only when absent.

What it actually says

dotfiles

  • mem0: repo-scoped memories use metadata={"scope":"repo","repo":"dotfiles"}.
  • scripts/*.sh are zsh — shellcheck refuses them (SC1071). Lint with zsh -n (pre-commit and CI already do); don't rename or port them to bash for shellcheck's sake.
  • ~/.claude/settings.json is deliberately not stowed (Claude Code rewrites it in place, replacing symlinks). Sync it via make backup → Backup/claude-settings.json; make install seeds it only when absent.
  • Verify changes with make doctor (script syntax + symlink health + Brewfile parse).
  • Backup/Brewfile is generated by brew bundle dump — hand edits survive only until the next make backup/make update; make durable changes by installing/uninstalling the package itself.
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.
