system-health

system-health is a skill for Claude Code from aksika/abtars. It costs 15 tokens per session (747 once invoked), scanned A, original, Apache-2.0.

A system diagnostic procedure that checks the agent's health, background tasks, heartbeat, sleep audits, memory database, and maintenance records.

In plain words
What is it for?
Use it when the agent appears unhealthy, scheduled work may be stuck, or memory and maintenance services need checking.
Why use it?
It helps separate real failures from known and accepted differences in the system. It provides a structured way to find stalled processes, stale locks, or missing maintenance activity.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code scans file system directories looking for sensitive files. This could be reconnaissance for credential theft.
    Fix: Remove unnecessary filesystem scanning. If file access is needed, use explicit, scoped paths. Avoid reading ~/.ssh, ~/.aws, or credential directories.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

system-health 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 10d 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.

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

System Health Check

Run a comprehensive health check and report only real issues — not known/accepted deviations.

Step 0 — Read known deviations

read docs/system-notes.md

Parse this file first. Any item described here is expected and must NOT be reported as an issue. Mention them briefly as "known & accepted" if relevant.

Step 1 — Doctor

~/.abtars/scripts/doctor.sh

Step 2 — Heartbeat

cat ~/.abtars/memory/.heartbeat  # epoch ms — if >10 min old, stalled

Step 3 — Cron / Tasks

# Use /tasks command or:
cat ~/.abtars/memory/cron-state.json

Step 4 — Sleep cycle

ls -lt ~/.abtars/memory/sleep/ | head -5   # last audit — if >2 days, broken
ls -la ~/.abtars/memory/sleep/*.lock 2>/dev/null  # stale locks

Step 5 — Memory DB

sqlite3 ~/.abtars/memory/memory.db "SELECT 'messages', COUNT(*) FROM messages UNION ALL SELECT 'extracted', COUNT(*) FROM extracted_memories;"
sqlite3 ~/.abtars/memory/memory.db "SELECT datetime(timestamp/1000, 'unixepoch', 'localtime'), substr(content,1,60) FROM messages ORDER BY timestamp DESC LIMIT 3;"

Step 6 — Consolidation

ls -lt ~/.abtars/memory/daily/ 2>/dev/null | head -3    # if >3 days, broken
ls -lt ~/.abtars/memory/weekly/ 2>/dev/null | head -3

Step 7 — Bridge logs

grep -i "error\|fail\|crash\|WARN" ~/.abtars/logs/bridge.log 2>/dev/null | tail -20

Step 8 — Backup

ls -lt ~/.backup-abtars/ 2>/dev/null | head -5  # should be <2 days old

Step 9 — Processes

ps aux | grep -E "abtars|kiro-cli|ollama" | grep -v grep

Step 10 — System resources

top -l 1 -n 0 | head -10
df -h /
uptime

Step 11 — Model availability

# Check configured models from transport.json
python3 ~/.abtars/scripts/scout-ollama.py

Reporting

Produce a concise report:

  1. Status: one-line overall (✓ healthy / ⚠️ degraded / 🔴 down)
  2. Services: gateway, channels (Telegram/Discord) — up/down each
  3. Issues: only NEW/UNEXPECTED problems (not in system-notes.md)
  4. Known & accepted: one-line summary like "3 known deviations acknowledged, all expected"
  5. Resources: disk, memory, uptime — only flag if concerning (disk >85%, etc.)

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.
