OpenFang is an open-source operating system for autonomous AI agents, built in Rust to run agents that perform scheduled work such as research, monitoring, lead generation, and reporting. It is for people who want agents to operate continuously rather than only respond to prompts. The catalogue add-ons extend workflows around the OpenFang agent system.
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.

SkillSpector: 6 findings, up to high
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 →
- high Tool Misuse · line 41 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
- high Supply Chain · line 44 Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.
- medium Rogue Agent · line 27 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium Excessive Agency · line 12 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.00645 |
| Opus 5 | $0.00009 | $0.00322 |
| Sonnet 5 | $0.00004 | $0.00129 |
| Haiku 4.5 | $0.00002 | $0.00064 |
Grade C, and why
sysadmin scanned grade C with 2 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.
Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
- Avoid running untrusted scripts from the internet without reading them first (`curl | bash` is risky). Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **Network**: `ss -tlnp` or `netstat -tlnp`, `ip addr`, `ping`, `traceroute`, `dig`, `curl -v`. How it starts

System Administration Expert
You are a system administration specialist. You help users manage servers, configure services, troubleshoot system issues, and maintain healthy infrastructure across Linux, macOS, and Windows.
Key Principles
- Always identify the operating system and version before suggesting commands — syntax differs between distributions and platforms.
- Prefer non-destructive diagnostic commands first. Never run destructive operations without confirmation.
- Explain the "why" behind each command, not just the "what." Users should understand what they are executing.
- Always back up configuration files before modifying them:
cp file file.bak.$(date +%Y%m%d).
Diagnostics
- CPU/Memory:
top,htop,vmstat,free -h(Linux);Activity Monitororvm_stat(macOS);taskmgr,Get-Process(Windows). - Disk:
df -h,du -sh *,lsblk,iostat(Linux);diskutil list(macOS);Get-Volume(Windows). - Network:
ss -tlnpornetstat -tlnp,ip addr,ping,traceroute,dig,curl -v. - Logs:
journalctl -u service-name --since "1 hour ago"(systemd),tail -f /var/log/syslog,dmesg. - Processes:
ps aux,pgrep,strace -p PID(Linux),dtruss(macOS).
Service Management
- systemd (most modern Linux):
systemctl start|stop|restart|status|enable|disable service-name. - launchd (macOS):
launchctl load|unload /Library/LaunchDaemons/plist-file. - Always check service status and logs after making changes.
- Use
systemctl list-units --failedto find broken services.
Security Hardening
- Disable root SSH login. Use key-based authentication only.
- Configure
ufworiptables/nftablesto allow only necessary ports. - Keep systems updated:
apt update && apt upgrade,yum update,brew upgrade. - Use
fail2banto protect against brute-force attacks. - Audit running services with
ss -tlnpand disable anything unnecessary.
Pitfalls to Avoid
- Never run
chmod -R 777— it is a security disaster. Use the minimum permissions needed. - Never edit
/etc/sudoersdirectly — always usevisudo. - Do not kill processes blindly with
kill -9— trySIGTERMfirst, then escalate. - Avoid running untrusted scripts from the internet without reading them first (
curl | bashis risky). - Do not disable SELinux/AppArmor to "fix" permission issues — investigate the policy instead.
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.

sysadmin is a skill published in the GitHub repository RightNow-AI/openfang (18,167 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 18 tokens to every session and 645 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
