affaan-m/ECC gained 458 stars on July 28 alone to reach 234,432 stars and 35,700 forks, making it one of the largest agent-tooling repos on GitHub. The v2.1.0 release ships 281 on-demand skills, 67 specialized subagents, an 'instincts' layer that extracts confidence-scored patterns from past sessions, and AgentShield — a security auditor that scans CLAUDE.md, MCP configs and hooks against 102 static analysis rules with an optional three-agent adversarial audit. Notably, despite calling itself a 'performance optimization system,' the MIT-licensed README publishes no quantified benchmarks — the claims are architectural (selective context loading, deterministic quality gates outside the model loop), not measured.
