System Service Registration

System Service Registration is a skill for Claude Code, Codex from llaa33219/casabot. It costs 12 tokens per session (1,240 once invoked), scanned A, original, Apache-2.0.

A manual for registering CasAbot as a systemd service, restarting it automatically, and scheduling it with cron. systemd is the Linux service manager that can start and supervise background programs.

In plain words
What is it for?
Use it to create and manage a CasAbot user service, enable persistent operation after logout, and check service status.
Why use it?
It provides the configuration needed to keep the agent starting on login, restarting after failures, or running without an active login session.

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is */5 * * * * podman exec monitor node /workspace/check.js >> ~/casabot/workspaces/monitor/cron.log 2>&1.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 Service Registration 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 7d 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.

System Service Registration

This manual explains how to register CasAbot as a systemd service, configure automatic agent restart, and set up cron scheduling.


1. Auto-start base (systemd user service)

Registering the CasAbot base agent as a systemd user service will automatically start it on login.

Create service file

# Create directory
mkdir -p ~/.config/systemd/user

# Write service file
cat > ~/.config/systemd/user/casabot.service << 'EOF'
[Unit]
Description=CasAbot Base Agent
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/env casabot
Restart=on-failure
RestartSec=10
WorkingDirectory=%h/casabot
Environment=NODE_ENV=production

[Install]
WantedBy=default.target
EOF

Enable and start service

# Reload daemon
systemctl --user daemon-reload

# Enable service (auto-start on boot)
systemctl --user enable casabot

# Start service
systemctl --user start casabot

Keep service running without login

By default, user services are stopped when there is no login session. To keep them always running:

# Enable lingering (keep service running after logout)
loginctl enable-linger $(whoami)

2. Check and manage service status

# Check status
systemctl --user status casabot

# View real-time logs
journalctl --user -u casabot -f

# View last 100 log lines
journalctl --user -u casabot -n 100

# View today's logs only
journalctl --user -u casabot --since today

# Restart service
systemctl --user restart casabot

# Stop service
systemctl --user stop casabot

# Disable service (disable auto-start)
systemctl --user disable casabot

3. Auto-restart sub-agents

Use podman container's --restart option to configure automatic restart for sub-agents.

Set at container creation

# Always restart (until manually stopped)
podman run -d \
  --restart=always \
  --name <agent-name> \
  --label casabot=true \
  -v ~/casabot/workspaces/<agent-name>:/workspace \
  -v ~/casabot/skills:/skills:ro \
  node:20-slim sleep infinity

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.

System Service Registration is a skill published in the GitHub repository llaa33219/casabot (5 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 12 tokens to every session and 1,240 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 2026-08-31.
