permissions
Claude Code Permissions Reference
Claude Code uses a tiered permission system to balance capability and safety. Permissions control which tools Claude can use and what resources they can access.
Permission Tiers
| Tool Type | Examples | Approval Required | "Don't ask again" Scope |
|---|---|---|---|
| Read-only | File reads, Grep, Glob | No | N/A |
| Bash commands | Shell execution | Yes | Permanent per project + command |
| File modification | Edit, Write | Yes | Until session end |
Rule Evaluation Order
Rules evaluate in order: deny → ask → allow. First match wins. Deny rules always take precedence.
