We install AL Development Collection (ALDC) 5.3.0 in a Business Central AL project that has never had it, and before asking for any work we check in the chat that the agents and the /al- commands are loaded.
What you'll see:
– The AL Development Collection 5.3.0 extension from the Marketplace.
– The "AL project detected" notification: you pick the project (Workshop, which holds App and Test) and the profile (BC29 native, the default it proposes). This path installs straight away, without a preview; to review the plan first, use Project Manager.
– Reloading the window so VS Code discovers the agents.
– Project Manager: the files match the installation receipt (133 managed paths). Whether VS Code loads them is not checked.
– Doctor: reads the configuration and finds App and Test. It doesn't compile anything or prove an agent works.
– In the Copilot chat: /al- lists the ALDC workflows as commands and the picker shows the agents (Architect, Spec, Conductor, Reviewer, Triage, Dredd…).
BCQuality and the MCP servers are left for episode 03.
Versions: ALDC extension and toolkit 5.3.0 (bc29-native profile), VS Code Insiders 1.146, GitHub Copilot Chat 0.74.2026111002 (Copilot harness, model Claude Fable 5), AL Language 18.1.2842859. Sample AL project with its workspace already organized: App and Test (platform 28).
