Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.00416 |
| Opus 5 | $0.00011 | $0.00208 |
| Sonnet 5 | $0.00004 | $0.00083 |
| Haiku 4.5 | $0.00002 | $0.00042 |
Grade A, and why
health-check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Health Check
Run all checks and report anomalies only (silent when healthy):
#!/bin/bash
ISSUES=""
# Disk > 85%
DISK_PCT=$(df / | tail -1 | awk '{print $5}' | tr -d '%')
[ "$DISK_PCT" -gt 85 ] && ISSUES="${ISSUES}\n⚠️ Disk at ${DISK_PCT}%"
# Memory > 90%
MEM_PCT=$(free | awk '/Mem/{printf("%.0f", $3/$2*100)}')
[ "$MEM_PCT" -gt 90 ] && ISSUES="${ISSUES}\n⚠️ Memory at ${MEM_PCT}%"
# Services down
for svc in openclaw-poe-gateway openclaw-argus-gateway; do
status=$(systemctl --user is-active $svc 2>/dev/null)
[ "$status" != "active" ] && ISSUES="${ISSUES}\n❌ $svc is $status"
done
# High load (> 4.0 on a typical system)
LOAD=$(uptime | awk -F'load average:' '{print $2}' | awk -F, '{print $1}' | xargs)
HIGH=$(echo "$LOAD > 4.0" | bc -l 2>/dev/null || echo 0)
[ "$HIGH" = "1" ] && ISSUES="${ISSUES}\n⚠️ High load: $LOAD"
if [ -n "$ISSUES" ]; then
echo -e "🚨 Health Issues:$ISSUES"
else
echo "✅ All systems healthy"
fi
When used in /loop, only alert when issues are found.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

health-check is a skill published in the GitHub repository JansenAnalytics/claudex (5 stars, last pushed 2mo ago), licensed MIT. It adds 22 tokens to every session and 416 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
