DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

CCR Agent Proxy: Selective Relay Mode

What

New environment variables give fine-grained control over which hosts the CCR agent proxy relays to, allowing direct dial for selected hosts while tunnelling everything else.

Details
  • CCR_AGENT_PROXY_RELAY_MODE — set to selective to only tunnel traffic to hosts in the include list; all others use direct networking
  • CCR_AGENT_PROXY_INCLUDE_HOSTS — comma-separated list of hosts that the selective relay tunnels; unlisted hosts use normal networking
  • CLAUDE_CODE_AGENT_PROXY_GH_SHIM — enable a GitHub CLI shim inside the agent proxy environment
  • CLAUDE_CODE_AGENT_PROXY_GIT_CONFIG — pass a git config string to the agent proxy environment
  • A startup reachability probe is logged as [agent-proxy] startup reachability probe: ok
Evidence

Selective relay log messages (search for "[agent-proxy] selective relay:" or "CCR_AGENT_PROXY_RELAY_MODE=selective but include-host").

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
