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
harnesskit
Adaptive harness for vibe coders — automatically detects your repo stack, applies experience-level guardrails (beginner/intermediate/advanced), observes sessions via zero-token shell hooks, and continuously improves your workflow by proposing custom skills, agents, and hooks based on real usage data. Marketplace-first: uses existing plugins, customizes only when data shows a gap.
ai.openhelm/dev-changes
Turn described changes into reviewed pull requests: propose, triage, review, dependency audits.
