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 5.1 | $0.00047 | $0.00636 |
| Opus 5.5 | $0.00019 | $0.00254 |
| Sonnet 5.5 | $0.00009 | $0.00127 |
| Haiku 4.5 | $0.00005 | $0.00064 |
Grade A, and why
sn-impact 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 3d 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 — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.
sn-impact — who depends on this?
Read-only analysis through the ServiceNow MCP server.
When not to use
- Something is already broken — start with sn-triage.
- Making the change itself — use sn-safe-write once the impact is known.
- A UI Builder page or experience — use sn-uib.
- Hand-offs (where the client has the plugin's subagents): a wide sweep over
many dependants goes to the
sn-investigatorsubagent, which returns the evidence without flooding the conversation; once the change is planned, pass the plan preview to thesn-change-reviewersubagent.
Steps
- Packages: this skill calls tools from
scripts,artifacts,flowsanddocs(the diagram), which the defaultdiscoveryprofile leaves off. ReadenabledPackagesinservicenow_get_status; for a missing package, enable it with the server'senable_packageadmin tool and tell the user, or ask the operator to add it toSN_TOOL_PACKAGES. A package listed indeniedPackagescannot be enabled — skip the steps that need it and report them as not checked. - Identify the target exactly:
servicenow_describe_tablefor a table or a field (type, reference, inheritance);servicenow_get_artifactorservicenow_explain_artifactfor a script, UI policy, flow or other artefact. - Where it is used:
servicenow_where_usedwithkindtable,fieldorscriptand thename. Setstructural: trueto add dictionary references, andscopeto stay inside one application. - Text references the structural pass cannot see:
servicenow_search_codewith the name (script includes, field names in GlideRecord calls). - What runs on the table:
servicenow_describe_table_logicand, for the operation you will change,servicenow_trace_table_event. - Optional picture:
servicenow_generate_er_diagramfor the table and its neighbours.
Output
A list of dependants grouped by kind (reference fields, scripts, automation, flows), each with where it lives (scope, table, sys_id), and a risk call: safe, needs coordination, or breaking. Say which sources were unreadable — an absent dependant is not proof there is none.
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-impact is a skill published in the GitHub repository IvanBBaev/servicenow-mcp-ai (8 stars, last pushed yesterday), licensed MIT. It adds 47 tokens to every session and 636 once invoked, about $0.0002 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 2026-09-27.
Other skills, from other repositories
debugging-mutations
Verify what changed on a ServiceNow instance after a tool call — sysaudit inspection, syslog/transaction logs, session context, Flow Designer execution logs, outbound HTTP traces.
inbound-email
Handle email arriving at a ServiceNow instance — inbound email action ordering and stop-processing, the real syseventinemailaction column names, and reading sysemail when a message created no record.
instance-performance-triage
Answer "the instance is slow" or "my nightly job never ran" from ServiceNow's own telemetry — transaction logs, syslog, systrigger, progress workers, execution trackers — instead of ad-hoc scripts that add to the load.
mcp-tool-discovery
Find and call tools on this ServiceNow MCP server — the two meta-tools it starts with, why a missing session id makes every other tool unreachable, which queries actually match, and which advertised tools are not on the server at all.
background-script-execution
What actually happens when you call snowexecutescript — the Scripted REST endpoint Serac auto-deploys on first use, the scheduled-job fallback, what scheduledjobpending means, and how to get output back when the call comes home empty.
change-rollback
Undo a change already written to a ServiceNow instance — recover the prior payload from sysupdateversion, write it back without corrupting it, and know which damage update set back-out, Deleted Records, or nothing at all can reverse.
