# VALIDATION_REPORT: Gemini CLI v0.23.0

**Date**: 2026-01-16
**Tester**: aget-framework (automated)
**CLI**: Gemini CLI (Google)
**CLI Version**: 0.23.0
**Environment**: macOS Darwin 24.6.0, Python 3.9.6
**Status**: VALIDATED (Infrastructure)

---

## Executive Summary

Gemini CLI v0.23.0 passes all 26 infrastructure validation tests. This validates that:
1. The CLI is installed and meets minimum version requirements
2. AGET file structures (AGENTS.md, .aget/, patterns/) are compatible
3. Python scripts execute correctly in the environment

**Important Distinction**: These are **infrastructure tests**, not live CLI session tests. Full behavioral validation requires live session testing.

**Note**: Gemini CLI is the newest of the three CLIs (0.23.x), so expect more rapid evolution.

## CLI-Specific Observations

### Differences from Claude Code

| Aspect | Claude Code | Gemini CLI | Impact |
|--------|-------------|------------|--------|
| Settings file | CLAUDE.md | Unknown | May need adapter |
| File reference | Plain text | `@filename` syntax | Different prompt format |
| Model | Claude | Gemini | Different capabilities |
| Maturity | Stable (2.x) | Early (0.23.x) | Expect changes |

### Gemini CLI Considerations

| Feature | Observation | Recommendation |
|---------|-------------|----------------|
| Early version | 0.23.x = early, expect breaking changes | Re-validate frequently |
| Settings unknown | May not read AGENTS.md | Test live session |
| File syntax | `@filename` for references | Document in CLI_SETTINGS_STANDARD |

---

## Gaps Identified

### GAP-001: Settings File Compatibility Unknown

**Severity**: Medium
**Description**: Unknown whether Gemini CLI reads AGENTS.md or requires different format.
**Impact**: May need GEMINI.md or different configuration.
**Recommendation**: Conduct live session test to determine settings file behavior.

### GAP-002: Live Session Validation Needed

**Severity**: Medium
**Description**: Infrastructure tests pass, but live session behavior not validated.
**Impact**: Unknown whether Gemini CLI follows AGENTS.md instructions in practice.
**Recommendation**: Conduct live session test with wake-up protocol.

### GAP-003: File Reference Syntax Differs

**Severity**: Low
**Description**: Gemini CLI uses `@filename` syntax for file references.
**Impact**: AGENTS.md instructions may need CLI-specific adaptation.
**Recommendation**: Document in CLI_SETTINGS_STANDARD.md.

---

## Live Session Validation Checklist

**TODO**: Conduct live session test to validate:

- [ ] Determine which settings file Gemini CLI reads
- [ ] Agent reads settings at session start
- [ ] Wake protocol executes when requested
- [ ] Wind-down protocol executes when requested
- [ ] File operations (read/write/edit) work
- [ ] Python script execution works
- [ ] L-doc creation works

---

## Conclusion

**Support Level**: COMPATIBLE

Gemini CLI v0.23.0 passes all infrastructure validation tests, indicating that AGET file structures and scripts are compatible. However, live session validation is needed to confirm full behavioral compatibility, especially regarding settings file format.

**Recommendation**: Upgrade to "Validated" after live session confirmation.
