compare-tech_skill

Overview

This skill helps you compare libraries, frameworks, SaaS products, or infrastructure options using a weighted scoring matrix. It produces a neutral, quantified recommendation with clear criteria, weights, and concise notes. The output is formatted for quick decision-making and easy sharing.

How this skill works

You start by defining the evaluation scope: the options and the target use case. Then select 5–8 criteria and assign weights that sum to 100, score each option 1–5 per criterion, and compute weighted totals. The skill returns a compact table, key differentiators, a winner with confidence, and any caveats to consider.

When to use it

• Choosing between competing libraries or frameworks for a new project
• Selecting SaaS vendors (monitoring, CI, analytics) with multiple trade-offs
• Evaluating infrastructure options (managed vs self-hosted)
• Comparing versions or forks when upgrading or migrating
• Shortlisting tools for procurement or architecture reviews

Best practices

• Limit criteria to 5–8 focused items and categorize as must/should/nice-to-have
• Assign weights totaling 100 using 15–25 for must-haves, 10–15 for should-haves, 5–10 for nice-to-haves
• Use score 3 as the neutral baseline and justify all deviations in Notes
• Cite primary sources for contested claims (docs, benchmarks, license text)
• Keep outputs concise: table, 1–2-line differentiators, and a short recommendation

Example use cases

• Compare React vs Vue for a single-page app with emphasis on ecosystem and hiring
• Choose between managed Postgres vs self-hosted for cost, reliability, and ops
• Decide on CI providers by weighing speed, integrations, and pricing
• Select an observability stack comparing vendor A vs vendor B on retention, scalability
• Evaluate authentication libraries focusing on security, ease of integration, and community
