guild vs. harness

Guild turns Claude Code into a self-evolving team of specialist agents for larger software tasks. It plans before execution, selects the right specialists, assembles focused context, preserves durable project memory, and improves its skills over time through evidence-based reflection. Instead of treating every request as a single long prompt, Guild breaks work into a governed workflow: clarify the goal, compose the right agent team, execute with scoped context, review the results, capture decisions, and only evolve specialists or skills when repeated evidence shows they are useful. When native agent teams are available, Guild coordinates them directly; when they are not, it falls back to sub-agents with the same planning and memory discipline. Guild is designed for projects where context, quality, and continuity matter: feature work, refactors, documentation, QA, release preparation, research-heavy implementation, and recurring workflows that benefit from reusable specialist knowledge.

Harness leverages Claude Code's agent team system to decompose complex tasks into coordinated teams of specialized agents. Say "build a harness for this project" and it automatically generates agent definitions (.claude/agents/) and skills (.claude/skills/) tailored to your domain.
