Status — Full System Overview
Shows background tasks, running processes, resource utilization, and lock files in one view.
Execution (main agent, 2-3 turns)
Run all checks in parallel:
1. Background Codex tasks
find .codex_tasks -name "status.md" 2>/dev/null | sort
For each status.md: extract STATUS, AGENT, TASK, NOTE.
For DONE/FAILED tasks, also read result.md.
2. Running processes
pgrep -a python 2>/dev/null | head -20
pgrep -a cmake 2>/dev/null
3. Resource utilization
nvidia-smi --query-gpu=utilization.gpu,memory.used,memory.total --format=csv,noheader 2>/dev/null || echo "No GPU detected"
free -m | awk 'NR==2{printf "RAM: %dMB used / %dMB total (%d%% used)\n", $3, $2, $3*100/$2}'
nproc
4. Lock files
for f in results/sweep.lock results/bench_pipeline.lock; do
if [ -f "$f" ]; then
echo "LOCKED: $f — $(cat $f)"
pid=$(grep -oP 'PID=\K\d+' "$f" 2>/dev/null)
if [ -n "$pid" ] && ! kill -0 "$pid" 2>/dev/null; then
echo " ⚠ PID $pid is STALE (process dead)"
fi
fi
done

Resource warnings (per standing policy §4)
- RAM > 24GB used:
⚠ WARNING: memory pressure (>80%)
- RAM > 27GB used:
🔴 CRITICAL: memory near limit (>90%) — consider killing lowest-priority process
- GPU > 0% while another GPU task planned:
⚠ GPU in use — do not launch training
If nothing is running
SYSTEM STATUS: idle
GPU: 0% | RAM: 12.1GB/30.0GB | No locks | No background tasks
Ready for work.
