| description | Generates GlideRecord queries, Script Include classes, and client scripts for ServiceNow legacy scripting. Use for Business Rules, Scheduled Jobs, server-side Script Includes, and client-side g_form/g_user scripts. Redirects to sn-sdk-fluent when Fluent SDK is detected in the workspace.

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 |

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.
