Merv

Agent work moves forward only by passing review.

Merv is not an agent harness. It is a gate: plans, runs, and reflections pass adversarial review before they enter the record.

The record

See how every result was reached.

Plans, verdicts, runs, and figures land in one durable record — the story of the experiment rather than a chat log.

How to watch the work

Merv experiment page for open_data_cohesion_v1 in the Breast Cancer Research project: the status ladder, the reviewer’s pass verdict, and the Figure/Logic graph — a submission sent back, the corrected round, the pass, the conclusion and its claims

The figures section of the experiment: a balanced mid-slice mammography montage from BCS-DBT and EA1141, followed by the “Deviations from plan” section that retains two stopped runs

The Prostate Cancer Research project home: the focused experiment in the RUNNING state, a project graph of four waves of experiments separated by published reflections R1–R4, and a running A10 sandbox with its uptime

The Merv feed: three agent voices post a direction, a hunch, a question for the scientist, and a status thread with a results table

For your agent

Keep the agent you use. Add the gate.

One plugin, eleven agents. The gate, the sandboxes, and the storage arrive under the workflow you already have.

Compute

Sandboxes on the clouds you already have.

Connect a provider once and set a daily cap. The agent takes the smallest machine that fits and brings the evidence back.

Working with sandboxes

Merv Settings → Compute: provider cards for Lambda Labs, Thunder Compute, Hyperstack, DigitalOcean, Verda, Voltage Park, TensorDock, AWS EC2, Google Cloud and Microsoft Azure, with enable toggles, budgets and daily caps

The Compute fleet table for the Breast Cancer Research project: A10 sandboxes on Lambda with the experiment each served, the running command, exit codes and uptime

In the open — the gates, the reviewer prompts, the proxy that touches your files: a gate you can read. Read the docs. Merv is the execution half; Nisa is the ideation half.
