Five starter workspaces, one per block. Clone the repo before entering the room, open your block folder in VS Code and execute the ALDC flow — from the first prompt to the final PR.
Each folder is self-contained. Open the one that corresponds to the block you are following. Block 04 has two variants — green field and brown field — that start from different contexts and are solved with different approaches.
The entry workspace for Block 01. Copilot set up with Instructions + Prompts and a reference HelloWorld.PageExt.al. Everything ready to practice the Context / Task / Constraints / Output pattern.
ALDC installed and ready. The densest block — the full 5-layer architecture is deployed here and Skills Evidencing is practiced in real time.
skill-diagnostics exercisesThe real ALDC flow with the three subagents. Includes the ALDC installation guide and the Barista Incidents case ready to run al-architect.
Barista Incidents from an empty extension. The PRD v0.1-live at Sprint 0 — al-architect generates the spec, al-conductor orchestrates the implementation.
Barista Incidents on an already-built foundation. The Circe Innovation · Barista Incidents 1.0.0.0 extension is installed. Ticket CRONUS-2026-042 is the entry point.
Everything runs locally. VS Code + AL Language extension + GitHub Copilot Chat + ALDC. Block 03 includes its own ALDC installation guide — for blocks 01 and 02 the first two are enough.

Nothing is implemented without an approved spec. The contract precedes the code, not the other way around.
Plan approval, phase commit, PR. A human signs off between phases — not at the end, between them.
Each agent declares which skill it loaded and which pattern it applied. Auditable by design.
La spec es el cerebro.
Los agentes son el sistema nervioso.
Everything presented in the workshop is open source — ALDC lives on GitHub under an open licence. This repo contains the 5 starters; the creator's notes are private.
