ServiceNow Legacy Scripting

ServiceNow legacy scripting uses the GlideRecord API for server-side data access, Script Include classes for reusable server-side logic, Business Rules for server-side automation, and g_form/g_user/g_list for client-side form manipulation. All APIs are described in the reference files below.

References

Read these files when you need them — do not pre-load all references at session start. Paths are relative to the skill root (the directory containing this SKILL.md file).

| File | When to Read | |------|-------------| | references/gliderecord.md | Generating or reviewing GlideRecord queries, CRUD operations, or addQuery/getValue patterns | | references/server-side.md | Generating Script Includes, Business Rules, or using GlideSystem (gs.) logging | | references/client-side.md | Generating Client Scripts using g_form, g_user, or g_list; or any client-side form manipulation | | references/gotchas.md | Before generating or reviewing any ServiceNow script — check for hallucination traps |

Scripts

| Script | When to use | |--------|------------| | scripts/validate-script.sh | When validating a ServiceNow script file for common issues before deploying |

Examples

Use these as structural templates — only read the example that matches your target type, do not pre-load all examples:

| File | Demonstrates | |------|-------------| | assets/examples/gliderecord-crud.js | Complete GlideRecord CREATE, READ (single and multi), UPDATE, DELETE with correct getValue() usage | | assets/examples/script-include-class.js | Script Include using Class.create() pattern with initialize(), utility methods, and type property | | assets/examples/client-script-gform.js | Client Script onLoad/onChange handlers using g_form.getValue(), g_form.setMandatory(), g_user.hasRole() |

Hard Rules

Never use GlideRecord when ServiceNow Fluent SDK is present.

If the workspace contains now.config.json, .now.ts files, or imports from @servicenow/sdk/core, the developer is working in a Fluent SDK application. Stop and redirect: "I can see you're working in a Fluent SDK project. Use the sn-sdk-fluent skill to generate typed metadata definitions instead of GlideRecord scripts. GlideRecord is the legacy scripting API and does not work inside Fluent SDK .now.ts files."

GlideRecord is server-side only — never generate GlideRecord in a Client Script. Use GlideAjax.

Always call query() before next() — while(gr.next()) without gr.query() never executes.

Use getValue() in loops — gr.field_name returns a pointer; gr.getValue('field_name') returns the string value.

Only use documented API methods — do not invent methods like gr.getField(), gr.setQuery(), or gr.addOrder().

Behavior by Task Type

Generating

Check for Fluent SDK signals first (Hard Rule 1) — if detected, redirect immediately; do not generate GlideRecord code.
Identify the script context: server-side (Business Rule, Script Include) or client-side (Client Script).
For server-side: read references/gliderecord.md for CRUD patterns, references/server-side.md for Script Include structure and Business Rule context variables.
For client-side: read references/client-side.md for g_form/g_user/g_list APIs. Never generate GlideRecord in a client script (Hard Rule 2).
Use example files in assets/examples/ as working templates.

Reviewing

Check Hard Rules 3 and 4: query() before next(), getValue() in loops.
Verify no GlideRecord in client-side code (Hard Rule 2).
Verify no invented methods — compare against references/gliderecord.md documented API (Hard Rule 5).
Run scripts/validate-script.sh <file> to check for GlideRecord in client scripts, bare setAbortAction, and g_form misuse.

Explaining

Route the developer to the relevant reference file for detailed method documentation.
For Fluent SDK questions, redirect to the sn-sdk-fluent skill.

Prompt

I am writing code for my ServiceNow project. My repository contains `now.config.json` and a `.now.ts` file. I need to fetch all active incident records where priority is 1. Please write the script for me to perform this query.

Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
