Now Sdk

by ServiceNow6f01c0e26cbeNo licenseListed Oct 8, 2026Updated Oct 8, 2026

Use whenever the user mentions fluent, ServiceNow, or the now-sdk, OR when the user prompts for edits within a fluent application (identified by a now.config.json at the project root). Also use when the user needs live instance data — looking up a sys_id, inspecting table columns or schema, checking whether a record already exists, fetching choice values, or reading role or scope info.

AI-generated overview

Guides use of the ServiceNow now-sdk CLI for fluent project orientation, SDK documentation lookup, and live instance queries.

What it does
This skill instructs an agent working in a ServiceNow fluent project (identified by now.config.json) to orient itself by running the now-sdk CLI: listing and reading SDK documentation topics, checking subcommand help, and querying live instance data. It defines a search, peek, then read workflow for the explain command and a query workflow for retrieving records, schema, choice values, and role or scope information as JSON. It also sets rules such as reading quickstart topics directly, not retaining query output as project knowledge, and confirming with the user before deleting fluent definitions.
When to use it
Use when the user mentions fluent, ServiceNow, or the now-sdk, or asks for edits inside a fluent application containing a now.config.json at the project root. Also use when live instance data is needed, such as looking up a sys_id, inspecting table columns or schema, checking whether a record exists, fetching choice values, or reading role or scope information.
Requirements
Requires the @servicenow/sdk package (explain needs version 4.6.0 or later; query needs 4.8.0 or later) runnable via npx, a fluent project with now.config.json, and network or instance access for live queries. Ships no scripts; instructions only.

Getting oriented — required before other work

Condition: the project root contains now.config.json (same role as package.json for an npm project — walk up from cwd to find it, and treat each one found as a distinct fluent project, not a nested copy of another). Action: run the orientation below for that project. Docs are versioned together with the @servicenow/sdk version installed per-project — orientation done for one project does NOT transfer to another. Re-run this for every distinct now.config.json you touch, even within the same session.

Step 1 — run all three:

bash
npx @servicenow/sdk explain quickstart --list --format=rawnpx @servicenow/sdk explain fluent-language --list --format=rawnpx @servicenow/sdk --help

Both lists are required — fluent-language is not a subset of quickstart.

Step 2 — read every topic returned by both --list calls in full, plus keys-file by name (not reliably tagged into either list). Read each topic once even if reachable multiple ways. Do not skip any. Do not --peek first — they are already pre-scoped, so peeking first is redundant overhead, not a safety step:

bash
npx @servicenow/sdk explain <topic> --format=rawnpx @servicenow/sdk explain keys-file --format=raw

Step 3 — treat this content as required working knowledge for the rest of this project's session. Do not re-derive fluent conventions from guesswork once they've been covered here — this includes safety-critical rules such as never deleting a Table()/BusinessRule()/Record() definition from a .now.ts file without confirming with the user first (deletion may need to propagate as an upgrade-time delete via keys.ts, which the code alone can't reveal). If uncertain later, re-run --peek on the specific topic rather than relying on memory:

bash
npx @servicenow/sdk explain <topic> --peek --format=raw

Rule: before using any subcommand for the first time, run npx @servicenow/sdk <subcommand> --help first — --help at the top level lists subcommands but not their flags. Never guess flag names.

SDK Documentation (explain)

Rule: never open a full topic without --peek first, except quickstart topics (covered in Getting oriented above — read those directly, no peek needed).

explain (including --peek and --list) is read-only documentation lookup with no side effects. Do not ask the user for confirmation before running it — peek and read relevant topics automatically as part of the task.

To show all available topics with their related tags:

bash
npx @servicenow/sdk explain --list --format=raw

To search for topics, showing the descriptions of all matches:

bash
npx @servicenow/sdk explain <topic> --list --peek --format=raw

To preview a topic:

bash
npx @servicenow/sdk explain <topic> --peek --format=raw

Once you are certain you want to read the full topic, open it like this:

bash
npx @servicenow/sdk explain <topic> --format=raw

What to search for

  • Metadata types — BusinessRule, Table, Acl, Flow, ScriptInclude, ClientScript, UiPolicy
  • Skills — workflows like build, transform, deploy, auth
  • Conventions — naming, structure, scoping, file-layout

For any task — always start here

Step order: search (--list) → peek (--peek) → read full topic. Repeat for every relevant topic — fluent behavior is often split across multiple topics, so stopping at one risks an incomplete picture.

  • Search: npx @servicenow/sdk explain <search-term> --list --format=raw
  • Peek: npx @servicenow/sdk explain <topic> --peek --format=raw
  • Read (only if peek confirms relevance): npx @servicenow/sdk explain <topic> --format=raw

If explain fails

  • explain is only available in @servicenow/sdk versions >= 4.6.0 — upgrade if the command is not found.
  • No documentation found for "<topic>" — wrong topic name, try --list
  • No match for "<topic>" — use a different search term

Live Instance Queries (query)

query is only available in @servicenow/sdk versions >= 4.8.0. If the command is not found, check the installed version and inform the user to upgrade.

Before writing any query call, run the subcommand help to get the exact flag names — the top-level --help does not show subcommand flags, so do not guess:

bash
npx @servicenow/sdk query --help

Then read the full usage guide and encoded query format guide for deeper context:

bash
npx @servicenow/sdk explain query --format=rawnpx @servicenow/sdk explain encoded-query-guide --format=raw

The required flag for filtering is -q / --query. Every query call needs it along with the table name. Always include the -o json flag to output machine-readable json.

bash
npx @servicenow/sdk query <table> -q '<query>' -o json

Rule: query output is live instance data, not documentation. Do not retain it as project knowledge the way quickstart topics are retained — treat it as scoped to the current task only.
