sandbox-advisor

A guide for understanding Claude Code sandbox permission errors, called EPERMs, and deciding when to rerun a command outside the sandbox.

In plain words
What is it for?
Use it when a Claude Code command fails because the sandbox blocks it and the command may need to be rerun without sandbox restrictions.
Why use it?
It turns an unclear permission failure into a short explanation and a suggested next action.

Getting it into your agent

Grade A, and why

sandbox-advisor 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 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.
