<h2>What's changed</h2> <ul> <li>Added AGENTS.md support: in a project with no CLAUDE.md, Claude Code reads AGENTS.md instead; change it under "Project instructions" in <code>/config</code> (not yet on Bedrock, Vertex or Foundry)</li> <li>Added <code>CLAUDE_GATEWAY_PROXY_IS_EGRESS_BOUNDARY=1</code> for Claude apps gateways whose only egress is a forward proxy: every outbound request hands the proxy the hostname instead of resolving it locally</li> <li>Added an optional <code>headers:</code> map on Claude apps gateway upstreams, to send static headers to a proxy you run in front of a provider</
