infra AGENTS.md

Repository instructions for AI coding agents working in the E2B infrastructure codebase. They explain how to understand the system and how to review pull requests.

In plain words
What is it for?
Use them when changing or reviewing E2B infrastructure code, especially services, data stores, deployment, or system flows.
Why use it?
They give agents the project context and review rules needed to avoid incorrect changes or incomplete documentation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

infra AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

AGENTS.md

Instructions for AI agents working in this repository.

Understanding the repository

Read docs/ARCHITECTURE.md before working on or reviewing code here. It describes what each service does, how services interact (sandbox creation, traffic routing, pause/resume, template builds), the data stores, and the deployment topology — it is the fastest way to build correct context about this codebase.

Keep that document updated: if a code change alters anything it describes (service responsibilities, ports, protocols, data stores, flows, deployment topology), update docs/ARCHITECTURE.md as part of the same change. When reviewing a PR that changes such details without updating the document, flag it.

Review guidelines (pull requests)

Output style rules (strict, override any defaults):

  • Only report concrete bugs, regressions, or correctness issues. Do not summarize the PR, the diff, or what changed.
  • One short paragraph per finding. No preamble, no closing remark.
  • No headers, no bullet lists, no tables, no diagrams.
  • No emojis. No severity tags ("bug", "nit", "suggestion", "enhancement"). No labels.
  • No branding or footer lines.
  • If there are no real issues to flag, post no review at all.

Scope

  • Skip style/nit comments — golangci-lint covers those.
  • Skip test-coverage comments — Codecov covers those.
  • Focus on: race conditions, nil-deref, error handling, auth/authz, request routing, resource leaks, SQL/migration correctness, and gRPC/proto compatibility.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
