servicenow-app-engine

servicenow-app-engine is a skill for Claude Code, Codex from Knuckles-Team/servicenow-api. It costs 179 tokens per session (1,324 once invoked), scanned A, original, MIT.

A guide to building scoped ServiceNow applications as code. ServiceNow is a platform for business workflows; a scoped application is a namespaced package of data tables, rules, permissions, menus, and request forms.

In plain words
What is it for?
Use it to plan an app’s structure, connect App Engine Studio artifacts to code, and assemble its data model, logic, security, navigation, and request experience.
Why use it?
It helps keep the application’s parts consistent when designing them as code instead of assembling them only through ServiceNow’s visual tools.

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

servicenow-app-engine 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 8d 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.

ServiceNow App Engine (scoped apps as metadata-as-code)

A scoped ServiceNow application is a namespaced bundle of metadata records (tables, rules, ACLs, menus, catalog items…). App Engine Studio (AES) / Application Studio build that bundle through a UI; this skill builds the same bundle as Fluent code and reconciles the two views. It defers the build/deploy/test mechanics to servicenow-sdk-lifecycle.

When to use

  • Designing a scoped app's shape: scope, x_ prefix, now.config.json, file layout.
  • Mapping an App Engine Studio artifact to the Fluent API that produces it.
  • Assembling a coherent app from multiple artifacts (data model + logic + security + nav + request UX).
  • Packaging/publishing a scoped app across instances.

When NOT to use

  • CLI lifecycle mechanics (init/build/transform/deploy/ATF) → servicenow-sdk-lifecycle.
  • Flow Designer flows/subflows/actions → servicenow-workflow-studio.
  • Reading the raw samples → servicenow-sdk-docs.
  • Ad-hoc live record CRUD → servicenow-table-api.

Prerequisites

  • A Fluent project (scaffold via servicenow-sdk-lifecycle → references/project-init.md).
  • For packaging/publish: the servicenow-api MCP server via the mcp-client skill. Env + tag matrix: agent-tools/mcp-client/references/servicenow-api.md.

The mental model

Everything in a scoped app is a record in a sys_* table, namespaced to a scope. Fluent constructs (Table, BusinessRule, Acl, ApplicationMenu, ServiceCatalog, Record, …) are typed emitters for those records. "Build the app as code" = author those constructs, then ship them via the SDK lifecycle.

Reference map — open just-in-time

  • references/scoped-app-anatomy.md — sys_scope, the x_<prefix>_ namespace, now.config.json, package.json, and the src/fluent/ layout. Read first when starting or structuring an app.
  • references/app-engine-studio-concepts.md — what AES / Application Studio are, their artifact vocabulary (data tables, experiences, logic-and-automation, security), and how a code-first project coexists with them. Read when reconciling with the UI.
  • references/metadata-as-code-mapping.md — the master table: App Studio artifact → Fluent API → canonical servicenow-sdk-docs sample. Read when you know what you want and need the construct + example.
  • references/full-app-walkthrough.md — assemble a working app end-to-end (table + business rule + ACL + application menu + catalog item), cross-referencing the samples. Read when building a whole app rather than one artifact.
  • references/packaging-and-publish.md — package and promote the scoped app across instances via servicenow_cicd + servicenow_update_sets. Read at release time.

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.
