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
Python Refactoring Assistant
Educational Python refactoring assistant that provides guided suggestions for AI assistants.
stetkeep
stetkeep stops Claude from refactoring code that's intentionally the way it is. Two pillars: 1) XML-structured behavior protocols (BRAIN/CRAFT/PERF, ~1.8K tokens each) encode routing, refactor discipline, and measurement-first performance rules using the XML tagging pattern Anthropic's prompting guide recommends for reliable parsing. 2) A 16-entry false-positive catalog of patterns Claude commonly mis-flags as anti-patterns: 1000-line constants files (not God Files, just data tables), V8-optimized .map.map.map chains, below-fold <img> tags, useMemo that fixes reference-equality bugs. No other plugin in the directory ships this. Enforcement is mechanical, not prompted: permission deny-lists, PreToolUse hooks (safety-net.sh / .ps1), tool-scoped subagents that cannot Write new files, and path-scoped rules that auto-load CRAFT/PERF on src/** access. Honest 5-layer breakdown in ARCHITECTURE.md §1. Supply chain hardened: zero runtime dependencies, OIDC Trusted Publisher (no long-lived npm token), Sigstore SLSA v1 p
