Edit

Surgical find-and-replace in a file. Scans for exact matches, changes only those, saves. Fails if no match — so you know the edit was applied.

Call run_skill with skill: "edit". Set command or arguments.action to edit.

Arguments

• arguments.path (required) — File to edit. Relative to workspace or absolute.
• arguments.oldString (required) — Exact string to find. Must match exactly (including spaces/newlines).
• arguments.newString (required) — String to replace it with. Use empty string to delete the match.

When to use

Use when the user says things like:

• "In Auth.js replace password with token"
• "Change the API URL in config to https://…"
• "Fix the typo 'teh' to 'the' in readme"

Only exact matches are replaced. If oldString does not appear in the file, the skill returns an error and the file is unchanged.
