I use Antigravity almost every day while building things. In the beginning, I was just running agents and connecting tools, but it still felt like I was doing a lot of work outside the flow.
Then I came across agent skills. They are basically plug-and-play capabilities that let your agent connect with different tools and actually get things done. I got curious and started trying them out in my own workflow.
That is when things started to click. I was not jumping between tools or writing extra logic for every step. I could use a skill and keep everything inside one flow. It made the whole setup feel much more natural and a lot less messy.
So in this article, I am sharing 10 useful skills you can use with Antigravity, what they do, and where they can help in real workflows.
1. Composio Skill - Connect agents to 1000+ SaaS apps in seconds
The Composio skill is what connects your agent to external tools and services. It gives you access to 1000+ tools through a single interface, so you don't have to deal with separate APIs, auth flows, or custom integrations for each one.
Everything shows up as simple actions your agent can call when needed. It also takes care of things like sessions, tokens, and maintaining stable connections, so you do not have to worry about the setup.
In real use, your agent can find a tool, connect to it, and run actions as part of one flow. It can pull data from one place, use it, and trigger something somewhere else without extra code. You can also chain multiple steps, handle errors, and react to events, which makes it work well for real workflows.
Why it matters
No need to deal with OAuth or token handling for every app toolkit
Works with different frameworks (Claude Agents SDK, Mastra, LangChain, Vercel AI SDK, etc), so you are not locked in
Handles sessions, errors, and execution flow for you
Supports triggers, so your agent can react to events for event driven workflows.
Who is it useful for: If your agent needs to talk to more than one tool, you will need this. It is useful for anyone building multi-step workflows or connecting to tools like GitHub, Slack, or other platforms where setup usually takes time.

You can also build and run custom scrapers, so you are not limited to predefined sources. In practice, your agent can collect live data, track updates, and combine multiple sources in one flow, working with fresh information that it can actually act on.
Why it matters
Gives your agent access to real-time web data
Supports many platforms out of the box
Returns structured data your agent can directly use
Let's you build and run custom scrapers
Helps avoid relying on outdated information
Who is it useful for: This is useful if your agent needs live external data. It works well for tracking prices, monitoring competitors, collecting leads, following trends, or building data pipelines.

The Metabase skill connects your agent to your internal business data. It lets your agent query databases using natural language, generate and run SQL, create dashboards, and surface insights using the semantic layer your team has already set up.
This means your agent is not just working with external data; it is working with the data that actually matters to your business.
Your agent can explore data, detect patterns, create visualizations, and even manage dashboards. It can turn plain questions into queries, refine results, and keep everything within your existing data permissions and structure.
Why it matters
Gives access to internal business data, not just public data
Converts natural language into SQL queries
Helps generate insights and dashboards automatically
Works within your existing data governance setup
Reduces the need for manual data analysis
**Who is it useful for: **Useful for teams that rely on internal data, like operations, finance, product, and analytics. It is also helpful for developers building agents that need to monitor systems or generate insights from structured data.

The Cloudflare skill gives your agent access to Cloudflare’s full developer and infrastructure stack. It covers topics such as Workers, storage, networking, security, and AI tools, and helps your agent choose the right service for the task. Instead of relying on static docs, the agent receives up-to-date guidance and patterns for building or managing systems.
Your agent can work with deployments, manage infrastructure, apply security rules, and build or update edge services. It can also generate production-ready setups using Cloudflare tools and follow best practices without you needing to look everything up manually.
Why it matters
Covers a wide range of infrastructure and edge services
Helps choose the right tools based on use case
Uses up-to-date documentation and patterns
Supports building and deploying directly on Cloudflare
Useful for both development and security workflows

The Remotion skill lets your agent create videos using code. It is built around the Remotion framework, where videos are defined using React components, animations, and data. This means your agent can describe a video and generate it without using a traditional editor.
It covers things like animations, captions, charts, media handling, and timing, so everything needed to build a video is handled through code.
Your agent can generate videos from data, text, or events, and control every part of the output. Since everything is code, the videos are repeatable, editable, and easy to update. It also supports advanced features like animations, audio sync, and visual effects, making it useful for more than just simple clips.
Why it matters

The Postman skill gives your agent a way to test and validate APIs before using them in a workflow. It acts as a pre-check layer, ensuring endpoints are working, responses are correct, and nothing breaks mid-run. It can also generate tests, update collections, and work with various APIs, including REST, GraphQL, and more.
Your agent can check APIs, catch issues early, and even automatically create or update test cases. This helps avoid failures during execution and keeps workflows stable when dealing with multiple external services.

Once you start using skills like these, Antigravity stops feeling like just another tool and starts feeling like a system that can actually get things done end to end. Each skill handles a specific part of the workflow, but together they cover everything from data and infrastructure to communication, content, and payments.
You do not need all of them at once. The real value comes from picking the ones that match your workflow and slowly building around them. Over time, you end up with flows that are cleaner, more reliable, and require less manual effort.
If you are already using Antigravity, trying out even a couple of these skills can change how you approach building. It is less about wiring things together and more about letting the system handle the heavy lifting.
