everything-claude-code: Agent Harness Optimization System Reaches 166K Stars
affaan-m/everything-claude-code has surged to 166,600 stars as a comprehensive agent harness performance optimization system covering skills, instincts, memory, security, and research-first development for Claude Code, Codex, OpenCode, Cursor and beyond. The JavaScript-based repo, created January 2026, provides a full optimization stack for coding agents — making it one of the fastest-growing Claude Code ecosystem repos this year. Its cross-agent compatibility (not locked to a single IDE or CLI) and focus on harness-level performance rather than individual prompts distinguishes it from typical skills collections.
