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.

Claude Code v2.1.178 15 Jun 2026

agent-proxy Replaces egress-gateway

What

Internal proxy component renamed from "egress-gateway" to "agent-proxy". All log messages now use the [agent-proxy] prefix.

Details

All [egress-gateway] log strings are replaced with [agent-proxy]
No behavior change; this is a rename that aligns with the component's role in agent communication

Evidence

Log string comparison (search for "[agent-proxy] enabled on 127.0.0.1:", "[agent-proxy] tunnel protocol v2 negotiated")

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