What it does
E2b is an agent skill from agent-sandbox/agent-sandbox. Core E2B SDK knowledge — correct imports, namespacing, terminology, and API patterns. Activates automatically when working with E2B sandboxes, templates, or code execution.
Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/api-reference.md` and `references/common-mistakes.md`).
It sits in Productivity & Automation. It works with Model Context Protocol, Git and Python. The repository describes itself as: Agent-Sandbox is an easy-to-use, enterprise-grade sandbox platform for AI Agents — letting them securely run untrusted LLM-generated code, Browser use, Computer use, and deploy… The licence is Apache-2.0.
When your agent uses it
- Productivity & Automation work in your project
Example prompts
- “/e2b”
Requirements
- Python 3
- A credential in E2B_API_KEY
What it can do on your machine
Read from SKILL.md and the folder at commit 6f7b273. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript and python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
E2B_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
E2b loads about 732 tokens when it runs, and up to ~3.9k if it reads all its reference files. Until then it costs about 44 tokens; SKILL.md has 238 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

E2B SDK — Core Knowledge
E2B provides sandboxes — secure, isolated Linux environments purpose-built as an AI agent runtime. Agents use sandboxes to safely execute code, run commands, manage files, and interact with git repositories.
Two SDK Packages
| Package | JS/TS import | Python import | Use when |
|---|---|---|---|
| Base SDK | import Sandbox from 'e2b' | from e2b import Sandbox | Templates, MCP gateway, sandbox lifecycle only |
| Code Interpreter | import { Sandbox } from '@e2b/code-interpreter' | from e2b_code_interpreter import Sandbox | Code execution with runCode()/run_code() + all base features |
Default choice: Use the Code Interpreter package — it includes everything from the base SDK plus code execution. Only use the base e2b package when you specifically need MCP gateway or don't need runCode().
Authentication
Set E2B_API_KEY environment variable or pass apiKey/api_key to SDK methods.
Critical: Correct Namespacing
All sandbox operations use namespaced methods:
| Namespace | Example (JS) | Example (Python) |
|---|---|---|
sandbox.commands | sandbox.commands.run('ls') | sandbox.commands.run('ls') |
sandbox.files | sandbox.files.read('/path') | sandbox.files.read('/path') |
sandbox.git | sandbox.git.clone(url, { path }) | sandbox.git.clone(url, path=path) |
WRONG: sandbox.run(), sandbox.read(), sandbox.clone() — these do NOT exist.
Critical: Sandbox Creation
Use Sandbox.create() — a static factory method. NEVER use new Sandbox() or Sandbox().
// ✅ Correct
const sandbox = await Sandbox.create()
// ❌ Wrong — constructor does not create a sandbox
const sandbox = new Sandbox()# ✅ Correct
sandbox = Sandbox.create()
# ❌ Wrong — constructor does not create a sandbox
sandbox = Sandbox()Critical: Timeout Units
| Language | Unit | Parameter name | Example |
|---|---|---|---|
| JavaScript/TypeScript | Milliseconds | timeoutMs | Sandbox.create({ timeoutMs: 60_000 }) |
| Python | Seconds | timeout | Sandbox.create(timeout=60) |
Terminology
- Use "sandbox" or "E2B sandbox"
- NEVER say "code interpreter sandbox", "ephemeral", "short-lived", or "cloud VM"
- E2B is an "AI agent runtime", not a "cloud provider" or "VM service"
- The main entity is
