# Decision Matrix ## What It Does Takes the guesswork out of tough decisions by applying structured frameworks. Instead of spinning in circles with pros/cons lists, you get a repeatable system for comparing options, weighting what matters, and reaching a conclusion you can explain and defend. --- ## Frameworks Available ### 1. Classic Pros & Cons (Benjamin Franklin Method) **Best for**: Quick decisions with low-to-moderate stakes | Step | Action | |------|--------| | 1 | Draw two columns: PROS and CONS | | 2 | List every reason for and against — no filtering | | 3 | **Weigh** each item (not all pros are equal). Assign +1 to +5 for pros, -1 to -5 for cons | | 4 | Sum the scores. A net positive suggests "yes." Consider emotional weight too | **Guardrail**: Pros/cons alone miss hidden assumptions. Always follow with: "What am I not considering?" ### 2. Weighted Decision Matrix (Pugh Matrix) **Best for**: Comparing multiple options against multiple criteria ``` | Criteria | Weight (1-5) | Option A | Option B | Option C | |------------------------|-------------|----------|----------|----------| | Cost | 4 | 8/10 | 6/10 | 9/10 | | Time to Market | 3 | 7/10 | 9/10 | 5/10 | | Strategic Fit

How do I install it?
Run `npx skills add cosmicstack-labs/mercury-agent-skills --skill decision-matrix --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From cosmicstack-labs/mercury-agent-skills, a repository with 364 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
