Model Editor: changes one model without breaking the rest
Model Editor changes one existing model with as little disruption as possible. You ask for a field, a renamed label or an extra choice in a status list. The agent returns a small edit plan, not a rewrite of the model. That matters because a model holds your real data, and a careless rewrite could cost you a column.
What it does
- Adds a field as a real typed column when it will be reported, filtered, grouped on a board or tracked in history.
- Changes labels, choice values and other properties by naming the exact field, not by position.
- Preserves the model identity, module, primary key, locked fields, permissions, indexes and everything you did not mention.
- Does not remove a field that holds data unless you explicitly ask for it.
- Reuses the built-in comments, attachments, activities, approvals, emails and call logs instead of adding equivalent fields.
- Explains in plain words what it will change, and only what it will really change.
When it helps
- A sales team wants a "Lost reason" field on deals. The edit adds one typed field and nothing else.
- You want a new stage in a status list. The agent adds the value and leaves the others in place.
- A manager asks to switch on approvals for expense claims. The agent turns on the built-in extension instead of inventing an approver model.
How it works with your data
Model Editor has no tools. It receives your request and the full definition of the one model, plus details of related models, and returns an edit plan. A separate part of Worknano shows the plan as a preview, and the change is only applied after you confirm it. Saving a configuration change can alter the database structure, so it is limited to people who may edit configuration. It uses a balanced model. It is a drafting agent, so it does not touch your records and it never applies a change on its own. Read the preview closely, especially when a request could remove or rename something that holds data.
Make it yours
This agent is a record in the Agents module. You can edit its instructions, for example to add naming rules, switch the model, adjust the temperature or duplicate it. The same model editor behaviour applies in every module, because they share one UI and one database design. Most requests arrive through the Meta Data Assistant. See Build your own agent and how to edit an agent.
