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 | $0.00043 | $0.03624 |
| Opus 5 | $0.00022 | $0.01812 |
| Sonnet 5 | $0.00009 | $0.00725 |
| Haiku 4.5 | $0.00004 | $0.00362 |
Grade A, and why
cmdb-patterns 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 464 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CMDB Patterns for ServiceNow
The Configuration Management Database (CMDB) is the foundation of ServiceNow ITSM, tracking all Configuration Items (CIs) and their relationships.

Creating Configuration Items
Basic CI Creation (ES5)
// Create a new server CI
var ci = new GlideRecord("cmdb_ci_server")
ci.initialize()
ci.setValue("name", "PROD-WEB-001")
ci.setValue("ip_address", "10.0.1.100")
ci.setValue("os", "Linux Red Hat")
ci.setValue("os_version", "8.5")
ci.setValue("cpu_count", 8)
ci.setValue("ram", 32768)
ci.setValue("operational_status", 1) // Operational
ci.setValue("install_status", 1) // Installed
ci.setValue("used_for", "Production")
ci.setValue("owned_by", "sys_id_of_owner")
ci.setValue("support_group", "sys_id_of_group")
var sysId = ci.insert()
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.

cmdb-patterns is a skill published in the GitHub repository serac-labs/serac (78 stars, last pushed 7d ago), licensed Apache-2.0. It adds 43 tokens to every session and 3,624 once invoked, about $0.0002 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 2026-08-30.
