ECC vs Gemini CLI

ECC leads on trust: 89.5/100 (Grade A) against 76.0/100 (Grade B), a 13.5-point gap. ECC leads on provenance and supply-chain integrity; Gemini CLI leads on adoption and rests on broader evidence. Note: ECC's evidence coverage is thinner (coverage B vs A) — its score rests on fewer independent signal types.

A ECC 89.5

The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.

Full evidence table

An independent, evidence-based trust comparison of ECC and Gemini CLI, two Coding Agents projects in the HVTracker registry. Scores come from public, checkable signals — supply-chain provenance, OSSF Scorecard, maintenance, and adoption — not popularity.

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption, scaled by an evidence-confidence factor. Grade bands: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Signals refresh daily. Full methodology v4.3 →
