ca-sandbox

v0.1.6

Locally-hosted Codespace equivalent for codeArbiter. Pulls an untrusted repo into an ephemeral, isolated Docker container with no host-filesystem access and configurable egress, caches dependencies by content hash, then tears the box down. Requires Docker and nixpacks on PATH.

Run Claude Code INSIDE a ca-sandbox box (`--with-claude`). Routed to when the user wants an agent loop running against an isolated, ephemeral sandbox rather than the host. Authenticates via an env-injected CLAUDE_CODE_OAUTH_TOKEN with no host bind of ~/.claude; the image pins the CLI and disables the autoupdater; HOME is backed by a named volume so the .claude state persists across restart. Five gated phases — posture, image, token, run, teardown. The hard default is offline or Anthropic-domains-only egress, and the token volume is NEVER co-mounted with an untrusted-code run; both are enforced, not advised.
