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
# Engineering Patterns Thirteen hard-won pattern guides for building tools and services, behind one catalog entry. Each guide is a **reference file** — read only the one that matches the problem in front of you, not the whole set. ## Pick the reference | If you are... | Read | |---|---| | Packaging a CLI — one-line install via `uv`/`npm`, subcommand dispatch, 3-tier config resolution | `references/cli-packaging-patterns.md` | | Writing a curl-piped installer for a stack that can't use `uv tool install`/`npm publish` | `references/one-line-installer-patterns.md` | | Persisting config and state — defaults merging, atomic crash-safe writes, XDG locations | `references/config-state-patterns.md` | | Building an HTTP service — FastAPI lifecycle, background poll loops, SPA + API proxy, WebSocket relay, SSE | `references/http-service-patterns.md` | | Adding auth or TLS — localhost bypass, token auth with auto-generation, automatic certificates | `references/auth-tls-patterns.md` | | Making processes talk through the filesystem — JSONL event logs, atomic snapshots, async request/response, SSE from file tailing | `references/file-ipc-patterns.md` | …

How to install
mdr add microsoft/amplifier-bundle-skills/engineering-patterns@sha256:db33ac3540dfa5faThe line at the top of this page pins the label git:20260907.03bded4, 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.
