Weighted criteria scoring for multi-option decisions — makes trade-offs explicit and defensible with sensitivity analysis.
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
# Decision Matrix **Make trade-offs explicit. Score each option against weighted criteria.** A decision matrix forces you to separate "what matters" from "how each option performs" — avoiding the trap of choosing the option you want and then finding criteria that justify it. --- ## When to use - Choosing between 2–6 alternatives with multiple competing criteria - Vendor/tool/technology selection - Architecture decision records (ADRs) with real trade-offs - When the team is split and needs a shared evaluation framework - When you need a defensible, transparent decision - Pairs with `/brana:swot-analysis` for strategic decisions; `/brana:six-thinking-hats` for perspective sweep before scoring --- ## Step 1 — Define the decision What are we choosing between? ``` AskUserQuestion: "What decision are we making? List the alternatives (2–6)." ``` --- ## Step 2 — Define criteria What factors matter for this decision? Generate 4–8 criteria. Each criterion should be: - Independently measurable (you can score options against it without circular reasoning) - Relevant to the decision (not just "nice to have") - At the right level of abstraction (not too broad, not too narrow) …

How to install
mdr add martineserios/thebrana/decision-matrix@sha256:f5005557e2097628The line at the top of this page pins the label git:20260615.6d899e8, 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.
