Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00067 | $0.00674 |
| Opus 5.5 | $0.00027 | $0.00270 |
| Sonnet 5.5 | $0.00013 | $0.00135 |
| Haiku 4.5 | $0.00007 | $0.00067 |
Grade A, and why
sn-advisor-router 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 6d 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.

SN Advisor Router
This skill routes ServiceNow advisory work. It is intentionally narrow so it can coexist with the official ServiceNow SDK plugin.
Use this skill when
First load ${CLAUDE_PLUGIN_ROOT}/references/configuration-policy.md, resolve
configuration, and enforce its activation and access gates. The task types below
are eligible only when the configured mode permits activation. In manual mode,
only explicit /sn-advisor or /advisor:sn-advisor invocation qualifies; in
disabled mode, stop.
- The user explicitly invokes
/sn-advisoror/advisor:sn-advisor. - The user asks for ServiceNow research.
- The user asks for current docs/community/support signals.
- The user asks for best practices.
- The user asks what to look out for.
- The user asks for risk assessment.
- The user asks for upgrade readiness.
- The user asks for troubleshooting context before action.
Do not use this skill when
- The user asks to create, edit, build, deploy, or implement ServiceNow code.
- The user asks to write Fluent SDK artifacts.
- The user asks to transform or deploy an app.
- The user asks for direct source changes.
For implementation, defer to the official ServiceNow SDK plugin.
Workflow
- Restate the task.
- Classify the ServiceNow domain:
- platform upgrade / release readiness
- UX / Next Experience / UI15 / UI16 / Workspace / UI Builder
- Service Portal / Employee Center
- ITSM process
- catalog / request / variables
- Flow Designer / workflow / approvals
- ACL / role / group / security
- CMDB / Discovery / Service Mapping
- integration / MID Server
- data import / transform maps
- notifications / events
- SLAs / schedules
- knowledge
- reporting / PA
- performance / technical debt
- Instance Scan / HealthScan-style review
- SDK/source-code task
- debugging / troubleshooting
- Load configured source policy, preserving the activation and access gates checked above.
- Search relevant online resources only when
web_search.enabledistrue. - Rank sources by trust.
- Pull read-only instance context through ServiceNow SDK auth profiles only when
instance_readonly.enabledistrueand it is useful. When disabled, do not discover profiles or contact an instance. - Produce the advisory brief.
- State explicitly that no changes were made.
- If implementation is requested next, hand off to the official ServiceNow SDK plugin.
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.

sn-advisor-router is a skill published in the GitHub repository mitchellOpZero/sn-advisor (3 stars, last pushed 7d ago), licensed MIT. It adds 67 tokens to every session and 674 once invoked, about $0.0003 per session on Opus 5.5. 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.
