Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
critical-thinking-tools
Critical Thinking Tools is a science-backed Claude Code plugin from Cognitive Bias Lab that helps users reason more clearly about decisions, beliefs, plans, forecasts, and disagreements. It provides structured thinking workflows based on research in psychology, decision science, forecasting, intelligence analysis, and debiasing. The plugin includes 12 practical tools: devil’s advocate review, pre-mortem analysis, outside-view forecasting, competing hypotheses, consider-the-opposite, steelmanning, Socratic questioning, base-rate audits, causal story dissection, calibration forecasting, decision journals, and groupthink red-team checks. Each tool guides Claude to produce structured outputs with likely bias risks, evidence that would change the conclusion, next actions, and a short science note. The plugin is designed as a practical judgment aid, not a guarantee of unbiased thinking, and emphasizes uncertainty, evidence updates, and careful reasoning.
