Individual skill
vendor-comparison-matrix
Compare vendors on a matrix that decides instead of decorates — the criteria weighted before the demos (so the shiny demo can't rewrite them), the evidence-based scoring with the marketing-vs-verified flags, the total-cost row that includes switching, and the reference-check questions that get honest answers. Use when asked compare these vendors/tools, build the selection matrix, the demo wowed us now what, or make this procurement decision defensible. Produces the weighted matrix, the scoring evidence rules, the TCO row, and the reference-call script.

# Vendor Comparison Matrix Skill
Vendor selections get decided by the best demo and then justified by a matrix built afterward — criteria reverse-engineered to bless the favorite, which is how the shiny interface wins over the boring integration that actually mattered. The honest matrix inverts the order: criteria and weights are set *before* the demos (from the requirements, with the must-have/nice-to-have line drawn), scores cite evidence (the [competitive-scan-lite](../competitive-scan-lite/SKILL.md) claimed/observed/verified flags), the cost row is *total* cost (license + implementation + training + the switching cost both ways), and references get called with questions designed to pierce the happy-customer screen.
## What This Skill Produces
- **The weighted matrix** — criteria × weights, set pre-demo, with the must-have gate separate from the scored nice-to-haves
- **The evidence-scored grid** — every score flagged: 📢 vendor-claimed / 👁 demo-observed / ✅ verified (trial, reference, docs)
- **The TCO row** — the all-in number per vendor: license, implementation, training, integration, and the exit cost
- **The reference script** — the questions that get past the curated happy customer
