my-servicenow-skill

my-servicenow-skill is a skill for Claude Code from jschuller/mcp-server-servicenow. It costs 48 tokens per session (560 once invoked), scanned A, original, MIT.

A template for creating a ServiceNow skill that documents its job, data tables, required roles, and whether it can make changes.

In plain words
What is it for?
It is for defining and testing custom ServiceNow skills and documenting the records and permissions they use.
Why use it?
It encourages clear permission and read-only boundaries, and tells the agent how to report denied or incomplete data instead of guessing.

Token cost

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.

Security

Grade A, and why

my-servicenow-skill 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 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.

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.

What it actually says

My ServiceNow Skill

One paragraph: the job this skill does, for whom, and what it never does (for example "read-only: it recommends changes and makes none").

Tables and roles

Table What it gives Readable with
incident What you read from it The least role that can read it

Declare every table your tool calls read in io.github.jschuller/servicenow-tables, and the roles in io.github.jschuller/servicenow-roles. If the skill calls a write tool, add io.github.jschuller/servicenow-writes with its name. Test the skill on a developer instance with an identity that holds exactly those roles.

When access is denied

  • 403 on a table: not assessable with this identity. Say which table and which role it needs. More access means another identity configured in the server; never ask for credentials in the conversation.
  • 0 rows or fields missing from every row (list_records adds a warning): possibly hidden by an ACL. Don't report "nothing found" as a fact.
  • aggregate_records refused (401 under API-key auth): count from list_records rows instead.

Workflow

Progress checklist:

- [ ] Step one
- [ ] Step two
- [ ] Report, separating facts from recommendations
  1. Write each tool call in a code block, as a call, so the validator can check it:
    list_records(table_name="incident", query="active=true^priority<=2", fields="number,short_description,priority,active", limit=20)
    
  2. Put long reference material in references/ and link to it: see the notes.
  3. Say what the report contains.

Tips

  • Request every field you filter on in fields=, so a hidden field shows up in the warning.
  • Write in your own words, and cite ServiceNow's documentation by link (see references/notes.md).
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
