Use when building an autonomous store or shop agent system (orders, catalog, delivery) — scaffolds the Waiter / Store Manager / Delivery pattern with bounded tools, an explicit state graph, and the receipt rule. From the Dev3Pack bootcamp.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Building an autonomous store — the Waiter/Manager/Delivery pattern ## When to use The user wants agents that take orders, manage a catalog, or fulfill deliveries — a shop, a café, a marketplace stall. NOT for general chatbots (no catalog, no fulfillment = no store). ## The pattern (three bounded agents, never one omnipotent one) - **Waiter** — the only agent that talks to the customer. Read-only tools over the Manager's catalog: `list_menu()`, `check_item(name)`, `quote(name, qty)`. Refuses unknown items and out-of-stock items with DIFFERENT, explicit reasons. - **Store Manager** — owns the catalog (items, prices, mints/SKUs, stock) and validates every order against it. The catalog is data the Waiter reads, not text pasted into prompts. - **Delivery** — an explicit state machine: `ordered → paid → delivering → delivered`, plus failure states (`payment_failed`, `undeliverable_zone`). Illegal transitions RAISE. Every transition appends a trace event. ## Workflow 1. Draw the delivery state graph in mermaid BEFORE coding; every arrow becomes a test. 2. Build the Manager's catalog as typed data (dataclass/JSON), then the …

How to install
mdr add gecko-academy/dev3pack-cohort-2026-09/store-builder@sha256:27ad413030d3a880The line at the top of this page pins the label git:20260904.280c57f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
