Claude Code adds sandbox.credentials to block credential access
TL;DR
Claude Code adds a sandbox.credentials setting that blocks sandboxed commands from reading credential files and secret environment variables.
What changed
Claude Code introduces a sandbox.credentials setting that stops sandboxed commands from reading credential files and secret environment variables. The update also applies organization model restrictions across all selection methods. Vibe Builders, Basic Users, and Developers will notice these controls in their secure workflows.
Why it matters
Basic Users gain protection when executing commands in shared sandboxes during routine tasks. Vibe Builders benefit in organization settings where model restrictions apply consistently unlike in some competitor environments such as standard AI coding assistants. Developers maintain tighter compliance without extra manual checks.
What to watch for
Developers should compare these controls against the standard terminal when testing new projects. Basic Users can verify the change by running a sandboxed command that tries to read an environment variable and confirming access is denied.
Who this matters for
- Vibe Builders: Use the sandbox.credentials setting to prevent AI agents from accessing sensitive local secrets.
Amy’s take
Claude Code is maturing into a production-ready tool by addressing the obvious security holes in agentic workflows. Blocking access to environment variables and credential files by default is a necessary step for any team running AI-generated commands locally. It prevents accidental leakage of API keys or database strings during exploratory coding sessions.
The enforcement of organization-level model restrictions is equally important. It ensures that builders stay within approved budget and compliance guardrails regardless of how they trigger the model. This update moves Claude Code away from being a loose experimental terminal toward a governed enterprise environment.
Operators should audit their current sandbox settings to ensure these protections are active before their next deployment.
