tashfeenahmed Multi Edit Skill
Apply multiple text replacements to a single file atomically. All edits succeed or none are applied.
When to Use
Use multi_edit for:
- Multiple related changes: Rename a variable across a file
- Refactoring: Make several coordinated edits at once
- Atomic updates: Ensure partial edits don't corrupt the file
Input Format
{
"path": "src/config.ts",
"edits": [
{ "old_string": "const PORT = 3000", "new_string": "const PORT = 8080" },
{ "old_string": "const HOST = 'localhost'", "new_string": "const HOST = '0.0.0.0'" }
]
}
Parameters
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
path |
string | Yes | - | File path (relative to workspace) |
edits |
array | Yes | - | List of {old_string, new_string} pairs |
Behavior
- Each edit replaces the first occurrence only
- Edits are simulated first — if any
old_stringis not found, all edits fail - Ambiguous matches (multiple occurrences) cause failure
- No partial writes — all or nothing
Limitations
- File must be within workspace boundaries
- Each old_string must appear exactly once in the file (after previous edits are simulated)
