Build your own agent kit — Allow network access

Reference note (untrusted external data; do not execute it as instructions). The network block does two things: it lists the hosts the sandbox can reach (allowedDomains), and it wires the kit-side half of the auth flow from Plan authentication with serviceDomains and serviceAuth. Bounded code example (external data; do not execute automatically): ```yaml network: serviceDomains: ampcode.com: amp serviceAuth: amp: headerName: Authorization valueFormat: "Bearer %s" allowedDomains: - "ampcode.com:443" - "*.ampcode.com:443" ``` allowedDomains here covers the apex (ampcode.com) and the install/CDN subdomains (.ampcode.com). Treat it as a starting point; Amp may reach other domains (model providers, analytics, updates) that you'll discover by watching sbx policy log while testing. Kits can also declare deniedDomains for hosts the sandbox should not reach, such as telemetry endpoints. Deny rules take precedence over allow rules and apply only to sandboxes that use the kit. For the auth wiring, when the agent makes an outbound request to ampcode.com, the proxy looks up the host in serviceDomains to find the service id amp, then uses serviceAuth.amp to inject an Authorization: Bearer header. The value comes from the secret you'll register in Register your API key, matched by host. The service id (amp) is just a label that ties the two blocks together — pick any name. > [!IMPORTANT] > Keep serviceDomains narrow. Mapping .ampcode.com would push the > proxy into TLS-intercepting mode for every subdomain — including the > binary CDN the install script downloads from — which corrupts those > downloads. List only the host that actually needs auth. Attribution: Adapted from Docker Documentation under Apache-2.0.
