# Start Modify Assistant

`POST /v1/templates/{template_id}/modify-assistant`

Start an EDIT-MODE setup assistant call to modify an existing template via AI.

Always creates a fresh interview + session — never resumes a prior one. The
edit-mode framing is composed at this layer:

1. The existing template's full JSON is rendered into EDIT_MODE_PREAMBLE
   and PREPENDED to the Setup Assistant's `system_instructions` (after
   its own {available_skills} placeholder is resolved). This puts the
   artifact-under-edit and the "you are not onboarding from scratch"
   framing at the very top of the agent's prompt.
2. The interview's goals are replaced with EDIT_MODE_GOALS — a single
   open-ended goal capturing what the user wants changed and why.
3. interviews.context.edit_mode_template_id = <template_id> tells the
   webhook (after the call completes) to run the edit-path synthesis
   and PATCH the existing template, instead of creating a new one.
