# VALIDATION_REPORT: Codex CLI v0.77.0

**Date**: 2026-01-16
**Tester**: aget-framework (automated)
**CLI**: Codex CLI (OpenAI)
**CLI Version**: 0.77.0
**Environment**: macOS Darwin 24.6.0, Python 3.9.6
**Status**: VALIDATED (Infrastructure)

---

## Executive Summary

Codex CLI v0.77.0 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 (e.g., "Does Codex CLI follow AGENTS.md instructions?") requires live session testing, which is documented separately.

## CLI-Specific Observations

### Differences from Claude Code

| Aspect | Claude Code | Codex CLI | Impact |
|--------|-------------|-----------|--------|
| Settings file | CLAUDE.md (symlink) | AGENTS.md (native) | None - AGET standard |
| Approval model | Per-operation | `-y` flag available | May need automation flag |
| Model | Claude | GPT-4/Codex | Different capabilities |
| Permission model | Granular | Unknown | Needs live testing |

### Codex CLI Advantages

| Feature | Observation |
|---------|-------------|
| Native AGENTS.md | Reads AGENTS.md directly, no symlink needed |
| OpenAI ecosystem | Integrates with OpenAI tools |
| Automation flag | `-y` flag for non-interactive use |

### Codex CLI Considerations

| Feature | Observation | Recommendation |
|---------|-------------|----------------|
| Version churn | 0.x series, rapid changes | Re-validate on major updates |
| Permission model | May differ from Claude Code | Test live sessions |
| Tool availability | Unknown tool set | Document available tools |

---

## Gaps Identified

### GAP-001: Live Session Validation Needed

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

### GAP-002: Tool Availability Unknown

**Severity**: Low
**Description**: Available tools (Read, Write, Edit equivalents) not documented.
**Impact**: May need different tool invocation patterns.
**Recommendation**: Document Codex CLI tool model in CLI_SETTINGS_STANDARD.

---

## Live Session Validation Checklist

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

- [ ] Agent reads AGENTS.md 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

Codex CLI v0.77.0 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.

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