Ecosystem

This library is useful on its own — install it, import a function, done. It is also part of a small ecosystem for Google Apps Script development, and two neighbours are worth knowing about.

Boot.gs — the application framework

Boot.gs is a framework for structured Apps Script applications. It brings controllers, decorators, dependency injection and a routing layer over doGet and doPost to an environment that otherwise offers global functions and nothing else.

npm install bootgs

import { Get, RestController } from "bootgs";

@RestController("api/sheet")
export class SheetController {
  @Get("active-range")
  getActiveRange(): string {
    return "This action returns the active sheet range.";
  }
}

The relationship to this library is a dependency, not a rivalry. bootgs lists apps-script-utils among its runtime dependencies, so a boot.gs project already has every function documented here, with no second install. The guards are what its parameter validation and its service lookups are built from.

Which to reach for:

You want	Use
Helpers inside a script you already have — a few functions, no new shape	`apps-script-utils` on its own
Routing, controllers, dependency injection, a web app with real endpoints	`bootgs`, with this library included

Agent Skills — teaching an AI agent this library

If you write Apps Script with an AI coding agent, the bootgs/skills repository publishes Agent Skills for it: packaged instructions an agent loads when a task touches a given topic. They work in Claude Code, Gemini CLI, Cursor and anything the npx skills CLI supports.

The catalogue splits in two:

Skill	Covers
`apps-script-utils`	This library: the `isX`/`nonX`/`requireX` convention, the guards, the helpers
`apps-script-triggers`	Simple and installable triggers, event shapes, quotas
`apps-script-services`	Quota-safe `SpreadsheetApp`, `PropertiesService`, `CacheService`, `LockService` use
`apps-script-ui`	Menus, sidebars, dialogs, and the `google.script.run` pitfalls
`apps-script-clasp-workflow`	The `clasp` CLI: push, deploy, versioning, multiple environments
`bootgs-quickstart`, `bootgs-*`	The framework above: project layout, architecture, validation, client, OpenAPI

Install into Claude Code:

/plugin marketplace add bootgs/skills
/plugin install apps-script@bootgs-skills

Install into any supported agent:

npx skills add bootgs/skills --skill apps-script-utils

Once installed, the agent applies the skill on its own when a task involves this library — it stops guessing at function names and starts using the ones that exist, with the validation convention the library actually follows.

A skill is a summary, though, and this site is the reference. When the two disagree, the pages here and the JSDoc they are generated from are what is current.
