The Application Load Balancer skill teaches agents to work with an Application Load Balancer as a product rather than as the objects it is stored in: create one, get the hostname to point DNS at, attach custom hostnames, add routes and the origins behind them, and configure traffic protection and authentication — all through datumctl alb. It also covers the policies the CLI does not wrap, for when you need WAF rule exclusions, rate limiting, circuit breaking or OIDC: TrafficProtectionPolicy, SecurityPolicy and BackendTrafficPolicy, attached via targetRefs.

​
Install

Once installed, the skill activates automatically when you ask an agent to work with Application Load Balancer on Datum. No further configuration needed.

​
Capabilities

  • Create a load balancer and get the generated hostname to point DNS at
  • Attach custom hostnames and follow their verification, DNS and certificate progress
  • Add routes and the origins behind them, by URL or by network service
  • Configure traffic protection (WAF), request headers and basic authentication
  • Read access logs for one load balancer
  • Attach the advanced policies the CLI does not cover: WAF rule exclusions, rate limiting, circuit breaking, OIDC
  • Preview every change before applying it
It also teaches the three ways this API’s status misleads a naive reader — conditions that report on several hostnames without naming one, a condition that is true when something is wrong, and two reasons set true to mean “does not apply” — so an agent does not report a problem that is not there, or miss one that is.

How it relates to other Datum surfaces

  • Product docs: Application Load Balancer — the human-facing reference for what an ALB is made of
  • Datum MCP: Datum MCP — for agents that need to read and write Datum resources during a session
  • datumctl: datumctl overview — the datumctl alb commands the skill teaches agents to use, plus apply, diff and delete for the advanced policies
