Operate a quack-on-demand FlightSQL gateway - boot/stop the manager, manage tenants/pools/ACLs, inspect nodes, run SQL.
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
# Quack on Demand Quack on Demand is a multi-tenant FlightSQL gateway in front of DuckDB Quack + DuckLake. The manager exposes a REST control plane (`/api/...`) and a React admin UI (`/ui/...`) on the same port (default `:20900`), a FlightSQL edge on a separate port (default `:31338`), and DuckDB's native Quack protocol on a third port (default `:9494`, for `ATTACH 'quack:host:9494'` from any DuckDB). Pools of Quack nodes are spawned as local subprocesses or K8s pods. Use this skill when the user wants to: - Boot, restart, or stop the manager - Create / scale / delete tenants and pools - Grant / revoke ACLs - Inspect node health, throughput, latency - See what SQL recently ran and where - Run ad-hoc SQL against the FlightSQL edge - Diagnose typical failure modes (dead nodes, expired sessions, ACL denials) ## Tooling Everything here runs through the `qod` CLI (PyPI package `qod`) against a live manager - no source checkout is needed. The pieces: - `qod start` / `qod stop` / `qod status` - run a manager from the released uber-jar (auto-downloaded and cached) against your Postgres; `qod setup` persists the `QOD_*` settings it needs …

How to install
mdr add starlake-ai/quack-on-demand/quack-on-demand@sha256:7a54914e799c7410The line at the top of this page pins the label git:20261106.b9ec1b7, 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.
