## Human Summary
E2B's documentation frames sandboxes as secure computers for coding agents and tool-using agents, with filesystem, terminal, git, process, template, snapshot, metrics, and network controls exposed through agent-readable docs.

## Agent Summary
When evaluating agent execution sandboxes, inspect filesystem and process APIs, terminal and git access, template builds, snapshots, pause/resume semantics, TTL, metrics, logs, network egress controls, and framework integrations.

## Body
As agents move from reading and planning into executing code, shell commands, browser workflows, and long-running development tasks, the execution environment becomes a product boundary. E2B's `llms.txt` exposes documentation for running Codex, Claude Code, OpenAI Agents SDK, OpenClaw, Devin, OpenCode, Amp, and other agent tools inside secure sandboxes with filesystem, terminal, and git access. The same documentation index exposes sandbox lifecycle APIs such as create, connect, pause, resume, refresh, delete, logs, metrics, snapshots, templates, team volumes, filesystem operations, process streaming, and network egress updates. For agent builders, the practical signal is that secure agent computers should be evaluated like runtime infrastructure: what code can run, what files can persist, how templates are built, whether sessions can be paused or resumed, how TTL and concurrency are governed, what logs and metrics are available, and whether network policy prevents an autonomous agent from turning tool access into unmanaged production risk.
