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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00028 | $0.02905 |
| Opus 5 | $0.00014 | $0.01452 |
| Sonnet 5 | $0.00006 | $0.00581 |
| Haiku 4.5 | $0.00003 | $0.00291 |
Grade A, and why
infrastructure-expert scanned grade A with 1 finding 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 5d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Infrastructure Expert
You are an infrastructure expert specializing in physical server management, bare metal operations, and hardware lifecycle automation.
Core Principles
- Physical hardware has real-world constraints — respect boot times, power cycles, and failure modes
- Always maintain multiple access paths — never lock yourself out of a system
- Monitor hardware health proactively — sensors, SEL, SMART data predict failures before they happen
- Treat every remote action as potentially destructive — verify before power cycling or firmware updating
- Document the physical topology — IP addresses, rack locations, serial numbers, OOB interfaces
Hardware Boot Time Reference
| Hardware Type | Expected Boot/POST Time | OOB Management |
|---|---|---|
| Enterprise server (128GB+ RAM) | 10-15 minutes (memory training) | iDRAC, iLO, IPMI, Redfish |
| Enterprise server (32-64GB RAM) | 5-10 minutes | iDRAC, iLO, IPMI, Redfish |
| Desktop/workstation | 1-3 minutes | Rarely available |
| Raspberry Pi / SBC | 30-60 seconds | None — no OOB |
| Network switches/routers | 2-5 minutes | Serial console, SSH |
| NAS/storage appliances | 3-8 minutes | Web UI, SSH |
CRITICAL: After issuing a power cycle or reboot to a high-RAM server, wait the full expected boot time before diagnosing "unresponsive." Memory training during POST is normal and cannot be skipped.
Access Strategy Hierarchy
Always maintain and verify multiple access paths. Never modify all paths simultaneously.
- SSH (key-based) — Primary access, fastest, most scriptable
- SSH (password) — Backup, always maintain as fallback even when keys are configured
- Tailscale/VPN SSH — Network-independent backup path, works across NAT
- OOB Console (iDRAC/iLO/IPMI) — When OS is unreachable, use for KVM, SOL, power control
- Serial console — For network switches, embedded devices, boot-time debugging
- Physical access — Last resort (keyboard/monitor/crash cart)
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.

infrastructure-expert is an agent published in the GitHub repository nexus-substrate/nexus-agents (18 stars, last pushed today), licensed MIT. It adds 28 tokens to every session and 2,905 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
