Use when starting any coding task — establishes the 97 trigger map so principles fire when relevant.
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
## Overview **97** distills established programming practice into trigger-based skills, in the spirit of *97 Things Every Programmer Should Know* (O'Reilly, ed. Kevlin Henney; CC-BY-3.0 originals at https://github.com/97-things/97-things-every-programmer-should-know). You have eleven themed skills plus this bootstrap. Each one activates on a specific situation — refactoring, writing tests, designing an API, reviewing code, committing — and brings the relevant principles to bear. Per-skill `principles.md` files list every source. Unofficial companion, not affiliated with O'Reilly or any contributor. ## **CRITICAL: invoke matching skills BEFORE any response or action** When a user message matches a row in the Trigger Map, you MUST invoke the named skill before taking any other tool action and before writing your reply. Use the `Skill` tool with the **bare skill name** (e.g. `before-you-refactor`). This rule is not negotiable: even a 1% match means invoke. The skill carries the checklist; skipping it means doing the work the default way and losing the point of having 97 installed. …

How to install
mdr add oribarilan/97/using-97@sha256:ce38be7fec71ed1eThe line at the top of this page pins the label git:20260510.17c5ab8, 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.
