What this does not tell you
Scores are percentiles of public GitHub signals. Nobody here tested these tools hands-on, so the higher score is not a verdict on which suits your project. Yellow marks the higher value.
Which one fits you
From measured data and licences, not from testing.
Pick Gemini CLI if
- You rely on thorough README docs (docs 69 vs 22).
Pick OpenCode if
- Recent activity and releases matter most to you (maintenance 76).
- You want the more widely adopted option (adoption 95).
- You want the tool whose automated scan found no issues.

Why different labels?
A label partly reflects how much of each tool is visible and scannable, not only how risky it is. A tool without a lockfile cannot get a dependency check.
- Gemini CLI: 9 critical-severity known vulnerabilities in runtime dependencies (OSV); Skill/agent file instructs piping a remote script into a shell: .gemini/skills/agent-tui/SKILL.md — curl -fsSL https://raw.githubusercontent.com/pproenca/agent-tui/master/install.sh | sh
