Agent Studio and Memories

Agent Studio is the four-step builder for custom agents inside the Composer: a name and description, some knowledge, a set of MCP servers, and a filtered tool list. Memories is the separate dialog listing the facts the Composer has saved about you from past chats.

Opening Agent Studio

From the Composer sidebar, choose Explore Nymphs to open the agent catalog, then Create Agent. To edit an agent you own, start a chat with it and click the pencil in the Composer header.

The catalog lists your agents and public agents together, with a search box and a My Agents filter. Clicking a card starts a chat with that agent. Custom agent chats run on GLM 5.

The four steps

Agent Studio fills the left side of the panel with a stepper. You can jump between steps freely; only Profile has required fields.

1. Profile. Give the agent a Name and a Description, both required. Custom knowledge is free-form notes carried into the agent’s prompt. Space Knowledge attaches whole Mantis spaces: paste a space link or id and press ↵, and connected spaces are listed underneath with a remove control.
2. MCP. Add one or more MCP server URLs. Quick add Mantis inserts the Mantis MCP server for you. Discover tools connects to each server, lists what it exposes, and moves you to the next step.
3. Tools. Every discovered tool appears grouped by server with a checkbox. Unchecking a tool records it as disabled for that server, so the agent is built with a filtered tool list rather than everything the server offers. The step reads “No tools discovered yet” until you have run discovery.
4. Review. Confirms the name, description, and visibility, then Create agent. Editing an existing agent shows Update agent and Delete agent instead.

Agents are created private.

Testing before you save

The right side of Agent Studio is a live test chat. It runs against a separate test socket using the form’s current values, so you can try an agent before it exists: the header says “Unsaved changes are used for testing”. It is text only, and the reset button clears the test transcript.

Teams

A Composer chat can be bound to a team as well as a single agent, and the backend has full team CRUD. There is no team builder in the Composer today: the frontend only reads an existing team by id. Chats bound to an agent or a team hide the mode selector and disable file upload and space attachment.

Memories

Open Settings at the bottom of the Composer sidebar. The dialog is titled Memories and lists what Mantis has saved about you, with a count badge and the note that memories let Mantis give more personalized responses.

Controls:

• Search memories filters on the memory text and its topics.
• The sort control offers Newest first and Oldest first. The list opens oldest first.
• The row menu has Delete, and shows the date the memory was saved from a chat.
• The panel menu has Delete all memories.

Memories are read only in this panel apart from deletion. You cannot write or edit one by hand: they are saved by the Composer during chats.
