Taking a mission through to a result
Building an app or improving a service involves assigning work, verifying it, reviewing it, and merging it alongside implementation. This Marblo update focuses on connecting those steps around a mission through the closed loop.
The orchestrator automatically assigns work, independent testers verify it, and reviews that have lingered receive a nudge. Work that passes proceeds to merge. People set direction and check results. The orchestrator, board agents, and system communicate to carry the intermediate steps forward.
This first build note introduces the features in this release. Part 2 follows the improvements to hypemarc.com from ticket creation through production deployment confirmation.
Eight new features in this release
| Feature | What your team can do |
|---|---|
| Closed loop | Automatic assignment → independent tester verification → nudges for lingering reviews → merge on passing |
| Agent Mosaic | Watch working agents' terminals together on one screen in real time |
| Orchebrain | Mission summary cards, development→testing→review dots, autonomous progress limits, and intake rate |
| Web Tabs | Open, read, fill, and test pages; delegate logged-in services without exposing cookies or passwords |
| Merge Train | Group verified PRs into one CI run and apply them to the default branch |
| Multiple AI accounts | Connect logged-in accounts without clicking and distribute work by remaining allowance |
| Risk-based independent testers | Have a separate AI tester check important changes, including counterexamples, while minor changes pass quickly |
| Telegram conversations with the orchestrator | Give instructions while away and receive progress and problem-cause reports |
Two ways to see progress: Mosaic and Orchebrain
Agent Mosaic brings working agents' terminals onto one screen so you can watch them simultaneously in real time. When several agents are working, you can see their progress together rather than moving between terminals.
Orchebrain shows progress by mission. Summary cards and development→testing→review dots show how far a mission has progressed. Teams can also manage autonomous progress limits and intake rate.
Use Mosaic to watch terminal activity and Orchebrain to follow the mission as a whole.
Continue work through Web Tabs and Telegram
Web Tabs let agents open, read, fill, and test pages. You can delegate a logged-in service to an agent while cookies and passwords remain unexposed.
Telegram lets you give instructions to the orchestrator while away and receive reports on progress and the causes of problems. Conversations with the orchestrator connect your team's direction and result checks to the work.
Distribute work by remaining account allowance
The multiple-account feature connects logged-in AI accounts without clicking. It checks remaining allowance to distribute work, spreading usage across the accounts you connect.
Add independent verification for important changes
For important changes involving payments, permissions, or deployment, a separate AI tester verifies the work, including counterexamples. Minor changes pass quickly, with verification handled according to risk.
During the hypemarc.com improvements, changes to security paths were automatically handed to an independent tester. A separate verification role examined the work produced by the implementing worker.
Group verified PRs with Merge Train
Merge Train groups multiple verified PRs into a single CI run before applying them to the default branch. It reduces the merge queue and CI costs.
The closed loop connects assignment, verification, review, and merging. Merge Train groups verified PRs for integration.
Preview: Marblo CI for local verification
Marblo CI is an upcoming feature. It aims to reduce GitHub Actions costs through local verification and signed receipts. The preview includes three CI modes:
- Off
- Important code only
- Always
The planned modes let teams choose how to apply CI. This preview is separate from the features introduced in this release above.
