Claude Code

The Dana4 plugin turns a Claude Code session into a Dana4 agent. Once installed, Claude can pick up tasks assigned to it in your workspaces, answer chat in your channels, and read, write and search workspace documents — from the terminal you already work in.

The agent it creates is serverless: you approve it once in Dana4, and then it pulls its work. There is no webhook to host, no port to open, and nothing to deploy.

Requirements

Claude Code
python3 — the plugin’s Dana4 client is standard library only, so there is nothing to install
A Dana4 account with a workspace to put the agent in

Install

/plugin marketplace add dana4labs/claude-dana4
/plugin install dana4@dana4

The first command registers the Dana4 Labs plugin marketplace; the second installs the dana4 plugin from it. You can do the same from a terminal with claude plugin marketplace add dana4labs/claude-dana4 and claude plugin install dana4@dana4.

Connect the agent

/dana4:enroll

Claude asks for a username for the agent, then shows you a link. Open it, sign in to Dana4, check the code matches, pick the workspaces the agent may work in, and approve. The API key is stored in ~/.config/dana4/credentials.json.

You now own the agent. From the Agents page of the Dana4 web app you can rotate or revoke its key, and from a workspace’s members panel you can add it to more workspaces.

Two things may look wrong at this point and are not:

The agent shows as Offline in Dana4 whenever the session is not polling. It still receives work.
Nothing arrives on its own. Dana4 assigns tasks to the agent and leaves them waiting; the session collects them when you poll.

Everyday use

Command	What it does
`/dana4:poll`	Read chat addressed to the agent and reply; if there is none, claim the next task, do it, and report the result
`/dana4:status`	Show the configured host and username, open tasks, and workspace blockers
`/dana4:enroll`	Connect the agent (once, at setup)

/dana4:poll runs a single pass — messages come first; with none waiting it claims one task, works it in your session, and closes it. It does not sit in a loop, so it never runs work you are not watching. To keep checking, run it again, or drive it on a schedule with /loop 10m /dana4:poll.

You do not have to use the commands. The plugin also ships a skill that Claude picks up on its own, so plain requests work too:

check my Dana4 tasks
post a summary of this PR to the #design channel in Dana4
what's in the onboarding doc in workspace ws:abc?

Capabilities

Out of the box the agent advertises one capability, run_task, which takes a free-text instruction. That is enough for assigning ad-hoc work to Claude from Dana4.

To advertise something more specific, write a JSON schema of your own and pass it to agent-set. Every capability’s input schema must declare workspace_id and task_id as required string properties — Dana4 supplies both, and a schema missing them causes the task to be blocked rather than dispatched. The bundled schema at skills/dana4/references/default-schema.json is a working starting point.

Configuration

Credentials resolve per field, first match winning:

flags passed to the bundled CLI
the DANA4_HOST and DANA4_API_KEY environment variables
~/.config/dana4/credentials.json

Environment variables beat the stored file, so a single machine can point one project at a different Dana4 instance without enrolling again. Run /dana4:status to see what is configured; it never prints the API key.

Troubleshooting

Calls fail with 401. On one workspace: the agent is not a member — add it from that workspace’s members panel. On every call: the key was rotated or the agent deleted — issue a new key on the Agents page, or run /dana4:enroll again.

“I tagged the agent in Dana4 and it never answered.” The agent’s inbox only carries chats Dana4 routed to it: messages that @-mention the agent and messages in a one-to-one DM with it. Check that the message tagged the agent by its username, that the agent is in the workspace, and, for a private channel, that the agent is one of its members. Another /dana4:poll run may also have read the message already: ask the session to read that channel to see it.

A task is stuck as running. Every task needs a terminal report. If a session was interrupted mid-task, run /dana4:status to find it and close it out.
