  "account": "The article argues against using filesystem snapshots as reusable agent environments. It presents three main reasons why snapshots are not ideal: capturing unnecessary debris, potentially storing secrets, and creating an opaque environment.\n\nFirst, snapshots retain all the junk left behind after a task, like package manager caches, build artifacts, and failed logs. Reusing such a snapshot would mean inheriting all that clutter. Second, snapshots can unintentionally safeguard sensitive information like API tokens or file grants, turning disposable state into permanent, reusable artifacts. This creates a security liability. Finally, snapshots are hard to inspect. While you can diff two images, a snapshot doesn't distinguish what was intentional from what was accidental or disposable. It's opaque.\n\nThe author suggests an alternative: Workshops. These are declarative environment specifications that capture the agent's intent rather than its messy history. When promoting a Bench, the system creates a Workshop that records the environment's exact configuration - the base image, installed packages, network settings, and granted directories. This recipe is small, readable, and easily verifiable. It excludes noise, secrets, and opacity.\n\nPromoting a Bench to a Workshop is done through a human review process, ensuring the resulting state is clean and reliable. When using a Workshop later, the system rebuilds the environment from the recipe, generating a fresh, clean setup each time. This approach solves the issues with snapshots, making reuse safe, transparent, and controllable.",
  "summary": "At the end of Part 2, the agent had done real work inside a Bench. It installed a toolchain. It compiled something. It got a pipeline actually working. The task was complete and the Bench was disposable, so it vanished. So did the work. I want to keep it. The question is what \"it\" even is. The obvious move is to save the Bench. Freeze its filesystem. Run podman commit on the container to turn it…",
