harnesskit

plugin Software development

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.
Description from the marketplace entry / plugin manifest.
