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
nlpm
NLPM lints, scores, fixes, and trend-tracks the natural-language artifacts that make up a Claude Code plugin — skills, agents, commands, rules, hooks, manifests — against a 50-rule rubric on a 100-point scale. Ships focused agents (scanner, scorer, checker, fixer, tester, security-scanner, vague-scanner, vocab-drift-scanner) and a standalone Python validator (bin/nlpm-check) that runs in pre-commit hooks and CI without Claude Code installed, plus a shields.io "Validated by NLPM" badge.
dev.agentopskit/constitution-lint
Static linter for CLAUDE.md-style agent constitution files: 10 operational-guardrail checks.
