| Rule | Details |
|---|---|
| Read first | Never modify unread files |
| Edit > Write | Use Edit for existing, Write only for new |
| Delete completely | No _unused prefixes or // removed comments |
| Match style | Follow existing conventions exactly |
| Minimal changes | Only what's requested |
Prevent:
exec('cmd', [args])textContent, not innerHTMLpath.basename()Glob: pattern: "**/*.js" # Find files
Grep: pattern: "func", output_mode: "files_with_matches" # Search
Read: file_path: "/path/file.js" # Read before edit
Edit: file_path, old_string, new_string # Modify
Parallelize independent Read calls. Chain sequentially: Read → Edit → Bash (test).
// Before: Bug - off-by-one error
function getLastItem(arr) {
return arr[arr.length] // Wrong: returns undefined
}
// After: Fix
function getLastItem(arr) {
return arr[arr.length - 1]
}
Change is minimal and targeted - only fix what's requested.
