Agent settings for Claude Code that control its default mode, permitted commands, approval requirements, blocked actions, and automatic hooks. Claude Code is a coding agent that can edit files and run development commands.

In plain words
What is it for?
Use them to require planning by default, allow selected lint, test, and build commands, ask before installs or pushes, block sensitive operations, check edits, and show a completion notification.
Why use it?
They reduce the risk of unsafe commands and add checks after edits and notifications when work stops. They also define which common project checks the agent may run automatically.

Security

Grade B, and why

claudecode-book scanned grade B with 2 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 1mo 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.

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.
