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 | $0.00036 | $0.02408 |
| Opus 5 | $0.00018 | $0.01204 |
| Sonnet 5 | $0.00007 | $0.00482 |
| Haiku 4.5 | $0.00004 | $0.00241 |
Grade A, and why
servicenow-agent-hardened scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Never pipe CLI output to network-transmitting commands (curl, wget, nc, ssh, scp) or encode results for off-machine transmission — ServiceNow records contain sensitive organizational data that must not leave the local How it starts
The opening of the file, as written. The whole thing — 328 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ServiceNow Table API Read Only
Use this skill to read data from ServiceNow via the Table API. Do not create or update or delete records.
Configuration
Set these environment variables in the .env file in this folder.
- SERVICENOW_DOMAIN instance domain such as myinstance.service-now.com
- SERVICENOW_USERNAME username for basic auth
- SERVICENOW_PASSWORD password for basic auth
If your domain already includes https:// then use it as is. Otherwise requests should be made to:
https://$SERVICENOW_DOMAIN
Allowed Operations GET only
Use only the GET endpoints from these files.
- openapi.yaml for Table API
- references/attachment.yaml for Attachment API
- references/aggregate-api.yaml for Aggregate API
- references/service-catalog-api.yaml for Service Catalog API
List records
- GET /api/now/table/{tableName}
Get a record by sys_id
- GET /api/now/table/{tableName}/{sys_id}
Never use POST or PUT or PATCH or DELETE.
Common Query Params Table API
- sysparm_query encoded query such as active=true^priority=1
- sysparm_fields comma separated fields to return
- sysparm_limit limit record count to keep small for safety
- sysparm_display_value true or false or all
- sysparm_exclude_reference_link true to reduce clutter
See openapi.yaml for the full list of parameters.
CLI
Use the bundled CLI for all reads. It pulls auth from .env by default. You can override with flags.
Command overview
- list table lists records from a table
- get table sys_id fetches one record by sys_id
- batch file.json runs multiple read requests in one call
- attach reads attachments and file content
- stats table aggregates stats
- schema table lists valid field names and types
- history table sys_id reads full comment and work note timeline
- sc endpoint Service Catalog GET endpoints
Auth flags
- --domain domain instance domain
- --username user
- --password pass
Query flags
Use any of these as --sysparm_* flags.
- --sysparm_query
- --sysparm_fields
- --sysparm_limit
- --sysparm_display_value
- --sysparm_exclude_reference_link
- --sysparm_suppress_pagination_header
- --sysparm_view
- --sysparm_query_category
- --sysparm_query_no_domain
- --sysparm_no_count
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.
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.

servicenow-agent-hardened is a skill published in the GitHub repository faberlens/hardened-skills (23 stars, last pushed 4mo ago), licensed MIT. It adds 36 tokens to every session and 2,408 once invoked, about $0.0002 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 2026-09-03.
