# Research – YOLO System Removal Verification

**Date:** 2026-01-26
**Owner:** Claude (research agent)
**Phase:** Research
**Git commit:** 84ce4ff3
**Git branch:** master
**Repo:** alchemiststudiosDOTai/tunacode

---

## Goal

Verify whether the YOLO (You Only Live Once) permission system has been completely removed from the codebase after the recent permission system deletion work.

---

## Findings

### Status: **COMPLETE** ✅

The YOLO system has been **fully removed** from the source code. Zero YOLO references remain in `src/` or `tests/`.

### Verification Results by File

| File/Directory | Status | Notes |
|----------------|--------|-------|
| `src/tunacode/tools/authorization/` | REMOVED | All `.py` files deleted. Only `__pycache__/` with `.pyc` files remains (harmless bytecode cache) |
| `src/tunacode/ui/commands/__init__.py` | CLEAN | `YoloCommand` removed from `COMMANDS` dict |
| `src/tunacode/core/state.py` | CLEAN | `yolo`, `tool_ignore`, `tool_handler` fields removed from `SessionState` |
| `src/tunacode/types/state.py` | CLEAN | `AuthorizationProtocol` removed |
| `src/tunacode/types/dataclasses.py` | CLEAN | `ToolConfirmationRequest`, `ToolConfirmationResponse` removed |
| `src/tunacode/constants.py` | CLEAN | No YOLO constants found |

### Current Commands (After YoloCommand Removal)

- `help`
- `clear`
- `debug`
- `model`
- `theme`
- `resume`
- `update`

---

## Remaining Artifacts (Expected)

### 1. Documentation/Research Files
- `memory-bank/research/2026-01-26_17-34-12_permission-system-removal-map.md` - Historical research doc (keep)
- `.tickets/psr-ba9c.md` - References YoloCommand removal (ticket should be updated/closed)
- `.tickets/psr-53c0.md` - References yolo field removal (ticket should be updated/closed)

### 2. Bytecode Cache
- `src/tunacode/tools/authorization/__pycache__/` - 11 `.pyc` files from previous compilation

**Cleanup command (optional):**
```bash
rm -rf src/tunacode/tools/authorization/
```

---

## Broken Imports/References

**None found.** All code references to the YOLO system have been successfully removed. No import errors or dangling references detected.

---

## Conclusion

The YOLO system removal is **functionally complete**. The permission system referenced in PR #246 and the associated research document has been fully implemented and cleaned up.

**No further action required** unless you want to:
1. Delete the `__pycache__` directory for cleanliness
2. Update/close the related tickets (`psr-ba9c`, `psr-53c0`)
