Editor Integration Principles
A good editor‑AI loop keeps the editor in control and the model on a short leash. Morph Apply makes that possible.
Preview Before Apply
Always show a diff preview before writing to disk.
Audit‑Friendly Output
Return clean merged files so the editor can log and review changes.
Scoped Context
Apply changes only to the selected file or diff scope to avoid side‑effects.
Minimal Apply Payload
Keep the apply call explicit and isolated to the file being edited.
Instruction + File + Update
<instruction>Extract the helper into a new function</instruction>
<code>function render(){ /* ... */ }</code>
<update>Create a new helper function and call it from render.</update>Editor Safety Checklist
Make your AI features feel trustworthy by default.
Trust Signals
- Always show a diff preview.
- Let users revert with a single click.
- Log the applied instruction alongside the output.
- Keep apply operations scoped to the selected file.
