Antigravity Skill Vault is a collection of reusable Agent Skills for Google Antigravity, covering software development, operations, security, and business work. It is for people who want Antigravity agents to follow specialized expertise, personas, and structured workflows. The catalogue skills are entries from this collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00042 | $0.02460 |
| Opus 5 | $0.00021 | $0.01230 |
| Sonnet 5 | $0.00008 | $0.00492 |
| Haiku 4.5 | $0.00004 | $0.00246 |
Grade A, and why
angular-migration 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 5d 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.
This is a copy
84% identical to angular-migration — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Angular Migration
Master AngularJS to Angular migration, including hybrid apps, component conversion, dependency injection changes, and routing migration.
Use this skill when
- Migrating AngularJS (1.x) applications to Angular (2+)
- Running hybrid AngularJS/Angular applications
- Converting directives to components
- Modernizing dependency injection
- Migrating routing systems
- Updating to latest Angular versions
- Implementing Angular best practices
Do not use this skill when
- You are not migrating from AngularJS to Angular
- The app is already on a modern Angular version
- You need only a small UI fix without framework changes
Instructions
- Assess the AngularJS codebase, dependencies, and migration risks.
- Choose a migration strategy (hybrid vs rewrite) and define milestones.
- Set up ngUpgrade and migrate modules, components, and routing.
- Validate with tests and plan a safe cutover.
Safety
- Avoid big-bang cutovers without rollback and staging validation.
- Keep hybrid compatibility testing during incremental migration.
Migration Strategies
1. Big Bang (Complete Rewrite)
- Rewrite entire app in Angular
- Parallel development
- Switch over at once
- Best for: Small apps, green field projects
2. Incremental (Hybrid Approach)
- Run AngularJS and Angular side-by-side
- Migrate feature by feature
- ngUpgrade for interop
- Best for: Large apps, continuous delivery
3. Vertical Slice
- Migrate one feature completely
- New features in Angular, maintain old in AngularJS
- Gradually replace
- Best for: Medium apps, distinct features
Hybrid App Setup
// main.ts - Bootstrap hybrid app
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { UpgradeModule } from '@angular/upgrade/static';
import { AppModule } from './app/app.module';
platformBrowserDynamic()
.bootstrapModule(AppModule)
.then(platformRef => {
const upgrade = platformRef.injector.get(UpgradeModule);
// Bootstrap AngularJS
upgrade.bootstrap(document.body, ['myAngularJSApp'], { strictDi: true });
});
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.

angular-migration is a skill published in the GitHub repository rmyndharis/antigravity-skills (1,480 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 2,460 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 84% identical to angular-migration, differing in 10 lines, and is treated as a copy.
