+# Quickwit Claude Guidelines
+
+## Code Formatting
+
+Run `make fmt` to check and fix code formatting. This command performs three checks:
+
+1. **Rust formatting**: Ensures Rust code is properly formatted (via `cargo fmt`)
+2. **License headers**: Checks that files are prepended with the correct LICENSE header
+3. **Log format policy**: Checks that log statements follow our format rules:
+   - No trailing punctuation in log messages
+   - No uppercase for the first character of log messages
+   - See `scripts/check_log_format.sh` for details
+
+### Quick Fix
+
+Use `/fmt` to automatically run format checks and see issues.
