Every connected agent has one of two settings for how its changes reach your diagrams.

Propose is the default. Your agent's changes to diagrams it created itself appear directly in either mode.

Choose or change the settingCopy Anchor Link

You choose the setting when you approve an agent, whether it signs in through your browser, with a code at lycana.ai/activate, or with an agent key you create. You can change it any time:

• In Settings → Connected agents, beside each agent.
• On a diagram, in the Connected agents menu at the top right of the canvas. The setting there is the same one, so changing it applies to all your diagrams.

An agent can't change its own setting. When it proposes a change, Lycana tells it that you can give it Full access, so it may suggest that to you.

What always waits for youCopy Anchor Link

In either mode, and even on a diagram the agent created, these changes are always proposals:

• Removing more than three objects. Links removed along with a node or boundary count, and so does everything inside a removed node's subcanvas, at any depth.
• Clearing a canvas.

An edit that only gives nodes new, empty subcanvases applies at once, even in Propose.

When an agent asks for reviewCopy Anchor Link

An agent with Full access can send a change as a proposal on purpose: over MCP it passes review: true, and with the CLI it runs lycana edit --review. Lycana asks agents to do this before changes you would want to check first, such as restructuring or replacing large parts of a diagram, removing or renaming what you drew, or guesses about your system, and not for routine additions.

In Propose, every change is a proposal already.

While a proposal waitsCopy Anchor Link

• On the canvas. The canvas toolbar shows the waiting proposal with its number of changes, Accept, and Reject, and brings its changes into view. You can open a list of the proposed changes and jump to each one.
• Before and after. Clicking an empty part of the canvas shows the diagram as it was, without the proposed changes. Clicking the number of changes, or an object the proposal touches, shows the proposal again. Accept and Reject work in either view.
• Locked objects. Until you answer, you and your agents can't edit, connect, or delete the objects the proposal touches. You can still move them.
• Teammates. In an organization, teammates aren't blocked. If one changes an object the proposal touches, the proposal can no longer be accepted, and you are told why.
• One at a time. A new proposal from the same agent anywhere in the diagram replaces its pending one.

How long the agent waitsCopy Anchor Link

After proposing a change, the agent waits about 50 seconds for your answer. If you haven't answered by then, it gets an id for the proposal and can wait again (with get_proposal over MCP, or lycana proposal on the command line). It doesn't assume the change is in the diagram until you accept it.

If you remove an agent in Connected agents, its pending proposals are rejected.

UndoCopy Anchor Link

Accepted proposals, and changes an agent with Full access applies directly, join the diagram's history. Your undo reverses them like any other change. Agents can't undo.
