Bound command output before it reaches the agent
Keep logs useful, retain failure status and separate a small diagnostic summary from full artifact storage.

Isolated execution, files, ports and bounded runtime.

Budget sandbox runtime around complete task stages
Allocate finite compute time, leave room for verification and distinguish running usage from command count.
Choose a browser or sandbox for the actual task
Match page interaction to Browser Run and command execution to hosted containers without inventing cross-product capabilities.
Control subprocesses and network effects in sandbox jobs
Distinguish isolated execution from external side effects, supervise child processes and bound network work.
Install sandbox dependencies as a controlled task stage
Inspect runtimes, use pinned manifests and verify installation without assuming the hosted environment includes every tool.
Keep credentials out of sandbox commands and logs
Use minimal workload credentials, protect temporary desktop links and understand what noEnv does and does not guarantee.
Make a sandbox workload portable through explicit artifacts
Move reviewed inputs, scripts and verification checks between execution environments without assuming live process or machine-image migration.
Make sandbox results reproducible enough to review
Record actual environment facts, pin inputs and retain verification evidence instead of treating a sandbox name as a reproducible build.
Manage a hosted sandbox from creation to stop
Track provider readiness, resource identity, command results and confirmed cleanup across a container task.
Manage multiprocess work inside a task sandbox
Keep process ownership, health checks and shutdown explicit when a synchronous command starts longer-lived work.
Plan an agent compute task before allocating runtime
Separate preparation, execution, verification and cleanup so hosted compute produces a concrete reviewable result.
Publish a sandbox port without exposing private work
Check the service locally, add application authentication and treat the returned HTTPS address as a public endpoint.
Read command results beyond HTTP success
Use exit codes, stdout, stderr and artifact checks to decide whether a hosted command actually completed its task.
Reconcile sandbox commands before repeating them
Preserve command identities, inspect history and artifacts, and distinguish API deduplication from application idempotency.
Set command timeouts without assuming cancellation
Distinguish client deadlines, provider request bounds, command timeouts and total sandbox runtime.
Stop sandbox runtime with a reviewable cleanup result
Export useful artifacts, stop application work and verify provider closure without claiming deletion or port revocation.
Transfer small sandbox files with integrity checks
Use base64 uploads and downloads within their limits, verify bytes and avoid treating a partial transfer as a valid artifact.
Understand a sandbox’s isolation and authority
Separate hosted execution isolation from command authorization, network access and secret handling.
Understand what stop and resume mean for a sandbox
Use the supported lifecycle without assuming memory checkpointing, permanent retention or unchanged processes after resume.
Verify agent code with a small local fixture
Use deterministic inputs and semantic assertions to test transformation logic without making paid or consequential live calls.
