dotfiles: Settings file for Claude Code

.claude/settings.json

dotfiles is a settings file for Claude Code from ahonn/dotfiles. Its token cost is not measured, scanned A, original, MIT.

A set of agent settings that configures environment variables, permissions, cleanup, attribution, and automatic hooks for events such as prompts and tool use.

In plain words
What is it for?
Use it to enforce project checks, update agent status, control tool permissions, run prompt-time scripts, and configure session housekeeping.
Why use it?
It centralizes recurring agent behavior so projects do not need to configure these rules manually for every session.

Settings file for Claude Code

Written for Claude Code: PreToolUse hook event. Also seen: names the AskUserQuestion tool; mentions AGENTS.md; mentions Codex.

This is ahonn/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 →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/yuexunjiang/.claude/hooks/herdr-agent-state.sh.

One of 8 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 7 are separate, each on its own page.

Reuse

Borrowing it

Nothing to install: this file belongs to ahonn/dotfiles. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

Security

Grade A, and why

dotfiles 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 16d 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.

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.
