- Move 7 loose top-level Markdown reports under docs/cleanup-2026-05/. - Relocate batch3_bloatware_uninstall.sh into phone_focus_mode/ where its ADB/phone wiring belongs. - Delete tracked out.json (empty puzzle_solver fixture). - Remove untracked clutter (mp4/wav/lcov/log/txt) from the working tree.

|
|
|
|
## Status: ✅ COMPLETE
|
|
|
|

## 🔧 How to Use
|
|
|
|
### For Developers
|
|
|
|
```bash
|
|
# 1. Write a shell script
|
|
nano scripts/my_monitor.sh
|
|
|
|
# 2. Stage and commit
|
|
git add scripts/my_monitor.sh
|
|
git commit -m "Add monitoring script"
|
|
|
|
# 3. Pre-commit runs automatically
|
|
# ✅ If compliant: commit succeeds
|
|
# ❌ If violations: see error + suggestions, then fix & re-commit
|
|
|
|
# 4. Reference: .copilot/instructions/shell.instructions.md
|
|
# When writing, Copilot shows R1-R8 rules with examples
|
|
```
|
|
|
|
### For Code Reviewers
|
|
|
|
1. Check that `no-polling-antipatterns: PASSED` in pre-commit output
|
|
2. Reference `SHELL_SCRIPT_QUALITY_GUIDELINES.md` for patterns
|
|
3. Use `QUICK_REFERENCE_SHELL_QUALITY.md` checklist
|
|
4. Point to specific R-rule in `.copilot/instructions/shell.instructions.md`
|
|
|
|
### For System Monitoring
|
|
|
|
```bash
|
|
cd /home/kuhy/testsAndMisc
|
|
|
|
# See resource report
|
|
./run.sh
|
|
|
|
# Find all anti-patterns in repo
|
|
./run.sh --diagnose
|
|
|
|
# Profile system for 30 seconds
|
|
./run.sh --profile 30
|
|
|
|
# Test hook manually
|
|
scripts/check_polling_antipatterns.sh path/to/script.sh
|
|
```

## 📊 System Impact
|
|
|
|
### Optimizations Already Active
|
|
|
|
| Component | Result | Daily Savings |
|
|
| ------------------ | ------------------------- | ----------------------- |
|
|
| network_monitor.sh | Zero fork timestamp reads | ~10ms/read |
|
|
| Battery polling | Interval 1s → 5s | ~80% fewer forks |
|
|
| Music daemon | Adaptive sleep | 83% reduction when idle |
|
|
|
|
### Expected Benefits
|
|
|
|
- **Prevention**: New scripts can't introduce fork-storms
|
|
- **Education**: Developers learn efficient patterns
|
|
- **Consistency**: All scripts follow same quality standards
|
|
- **Maintenance**: Easy to enforce via pre-commit
|
