fig. 02—Commander features
Your projects, agents and code in one interface.
Six groups of tools to prepare your environments, work with your agents and take changes through to delivery.
Projects and isolated workspaces
Group your repositories and create a workspace for each change, isolated in its own Git worktree. Commander automatically prepares its branch, directory and dependencies, plus a database copy and local site for Laravel + Herd projects. Open configured previews, archive workspaces you want to set aside and restore them when needed.
Claude Code and Codex in each tab
Choose Claude Code or Codex for each agent tab and resume conversations saved in the workspace. Track activity statuses and find questions, permission requests and completed turns in “Waiting for you”. Configure notifications to know when to step in.
Terminals, commands and notes
Open terminals alongside your agents and run the project’s npm and Composer commands in their own tabs. Reuse instructions with Quick Texts and keep project notes in automatically saved notepads.
Diffs and agent-assisted review
Browse changes file by file, compare your work against the base branch or latest commit, and inspect the diff of a specific commit. Comment on lines that need attention, then send your review comments to an agent to address.
Commit, push, PR and merge
Create commits, push the branch, open a pull request or merge into the base branch. When a conflict occurs, see the affected files and launch an agent to resolve them. You stay in control of concluding or aborting the merge.
Briefboard and MCP coordination
Browse Briefboard tasks and milestones and create a workspace from their prompt. Through the local MCP server, an agent can discover existing workspaces, launch an agent in a new workspace in another project and pass notes to it.

01 /
Start a piece of work
Add a local repository, create a workspace and launch an agent with your instructions. You can also start from a Briefboard task or milestone.
-
02 /
Test with your tools
Open a terminal, run project scripts and visit preview URLs when configured. Open the folder in your editor when you want to work on the code yourself.
-
03 /
Review the actual changes
Browse diffs by file or commit. Add comments to the lines that need attention and send them to an agent to address.

04 /
Decide how to finish
Commit, push and open a pull request, or merge into the base branch with conflict management. Archive the workspace to return to it later, or clean it up when the work is finished.
fig. 04—Delegate across projects
“This feature needs an API change too.”
The agent working on your app can launch an agent in another Commander project, with a new workspace and instructions. The API work appears in the same interface, so you can follow both changes and step into either one.
The local MCP server lets agents inspect existing workspaces and leave notes for each other. A note is delivered with the recipient’s next prompt.

Turn Briefboard tasks into working branches.
Connect a Briefboard project to browse its tasks, task details and milestones in Commander. Starting a task proposes a branch name; you can mark the task in progress and launch the agent with its prompt. Finishing the workspace adds the outcome and a change summary to the linked task or milestone.
You can also use Commander directly with local repositories, without linking a Briefboard project.
Explore the project context provided by BriefboardStay in control from first prompt to pull request.
Commander brings agents, workspaces and code review together. Connect Briefboard to start from documented tasks and keep the outcome in your project’s history.
