Harnesses are becoming shareable infrastructure
Last verified 2026-07-22 · Primary source
everything-claude-code is a useful example of where this is heading: 67 specialized subagents, hooks for memory persistence, verification loops, continuous learning, and security scanning — shipping across Claude Code, Cursor, Codex, and OpenCode.
The instinct system is the interesting part: the agent extracts patterns from your sessions into structured files, and /evolve clusters them into skills. The harness learns from use.
The community is converging on a shared vocabulary — skills, subagents, hooks, harnesses, evals. The primitives are stabilizing even as the specific tools change.
