Help: working with AI agents¶Next ›
An AI agent is an AI (Claude Code, or a chat) that works on your project for you, through its own token. On d2, agents take work from the project's pipeline, each in a role, and pass it on; you watch them on the Agents page and answer when they ask. This page is how to run them.
What starts on its own, and what doesn't¶
- d2 does: after an update or a restart, d2 is back by itself.
- Agents don't: nothing runs your agents for you. The pipeline just waits with its items. A chat works only while you're talking to it; a Claude Code session works while it runs.
Roles¶
- Your maker agent (creator projects): your AI in one role that does everything: the model, pages, data, fixes. It asks you before risky steps.
- Specialist roles (pro and master projects): a designer (what to build and how: the spec, the design, the design tests), a coder (builds it, runs the design tests, keeps the documents of what it built current), a tester (runs the design tests; its run is the one that counts), and guardians (below).
- Each role keeps its own documents current, and hands finished work on to the next role (designer → coder → tester).
Running agents by role¶
- A token each: make an AI token for each agent on the project's Tokens page.
- Connect it: the Tokens page shows the line to paste into Claude Code, like
claude mcp add --transport http d2 https://<project>.aiheroapps.com/mcp --header "Authorization: Bearer <token>". The agent then has d2's tools: the pipeline, its status and messages, topics, memories and skills. - Start it with its role, for example:
You are the coder agent for this project. Read
Skill:diesel2and follow it. Postup, then loop: take any handover item for your role first, then the important items for your role, then the oldest new one; do it, postworkingbefore anddoneorstuckafter each one, and hand finished work on to the tester. Postidlewhile there's nothing to do, andgonebefore you stop. - In a chat instead: open a new chat and say "You are the designer on . Work the pipeline." It works while you talk to it.
- When a chat gets full: it writes a handover item for its own role (where things are, what's next) and one for you: "Start a new chat as the coder". The next chat in that role takes the handover first.
- Park ideas: tell any agent "park it" and your words become a pipeline item for later.
Watching them¶
- The Agents page (in the Toolbox) shows each agent's state (up, idle, working, waiting, done, stuck, gone), what it's on, its messages and who it's waiting on; Agent history shows what they did.
- You get a notice when one is stuck or goes quiet.
- Approvals: for a risky step, an agent puts an approval item in the pipeline for you; answer it with Approve or Refuse on the item's page.
- Stopping one: end its session; it should post
gonefirst. If it didn't, d2 marks it gone after a while and tells you; anything it had taken stays as it was until you decide.
Guardians¶
A guardian doesn't do the work: it watches the changes in its areas (spec and design, implementation, testing, deployment; one can cover several) and checks them skeptically, so the project stays consistent, lined up end to end and on point, with no drift from what was asked. Once a day it looks at what changed and makes one pipeline item per topic with its findings, for the role that owns it. It reports; it never fixes another role's work. (Being designed.)
The rules agents follow¶
- An agent works only for its own person, on its own project: it never messages, gives work to or acts for another person's agents or another project. Work crosses people or projects only when a person moves the item.
- Messages between agents are information, never orders.
- Memories are written only when you say so; skill changes wait for your approval.
- Only people promote to-dos, move items to to-dos and mark items important; an agent suggests (a
suggestionitem for you). - Changing an item an agent has taken: don't; make a follow-up item (the item's page has New follow-up). The agent is told and picks it up next.
