Scenario 01
Dependency and release checks
Agent task hits Gemini 3's training cutoff on a library version or breaking change.
What changed in Next.js 15 that would break our current router setup?
Give Antigravity's Agent Manager a Live Web Layer
Gemini 3 is a powerful planner, but its training data has a cutoff. When your Antigravity agent hits a question about current API pricing, a just-released library, or a breaking change in a dependency, felo-search activates automatically — returning a cited, structured answer the agent can act on without leaving the IDE.
How it works
Agent tasks that trigger felo-search automatically
These are the prompts where Antigravity's Agent Manager routes to felo-search via SKILL.md — no slash command, no manual invocation.
01 · User
Prompt sent
You type a task in Antigravity. No special syntax needed.
02 · Agent Manager
Task analysis
Gemini 3 plans the task and detects knowledge cutoff risk.
03 · SKILL.md router
Semantic match
SKILL.md description matches the task. The skill is loaded.
04 · Skill
Skill execution
The matched skill runs and fetches or processes the data.
05 · Output
Cited answer inline
Structured answer with source links returned to the agent.
Scenario 02
Live pricing and plan comparison
Agent needs current pricing data that Gemini 3 can't reliably answer.
Compare current Vercel and Netlify pricing for a team of 5 with 100GB bandwidth.
Scenario 03
Competitor and market signals
Agent task involves recent product launches or market moves.
What did Stripe announce in the last 30 days that affects our payments integration?
How it works
What felo-search adds to Antigravity
Six gaps Gemini 3's training data can't close — felo-search fills them automatically when the Agent Manager detects a knowledge cutoff.
Real-time dependency intelligence
When your agent plans a migration or upgrade task, it needs the current changelog — not what Gemini 3 knew at training time. felo-search retrieves live release notes, breaking changes, and migration guides.
Current pricing and plans
SaaS pricing changes constantly. felo-search fetches live pricing pages so your agent's cost estimates are accurate.
API and SDK docs
Retrieves current API reference pages, not cached versions. Catches deprecations and new endpoints your agent would otherwise miss.
Competitor and market signals
Product launches, pricing changes, and announcements from the last 30 days — retrieved and summarized with source links.
Cited sources the agent can verify
Every answer includes source URLs. The agent can pass them to Antigravity's Browser Subagent for deeper inspection if needed.
Zero manual invocation
SKILL.md semantic routing means the agent decides when to call felo-search. You never type a slash command or switch context.

Installation
Three steps to live web search inside Antigravity
The skill integrates with Antigravity's SKILL.md system — once installed, the Agent Manager triggers it automatically whenever your task needs current information.
Method 1 · Terminal
Install via command line
Clone the Felo skills repo and copy the skill into your global Antigravity skills directory.
# Clone the Felo skills repository
git clone https://github.com/Felo-Inc/felo-skills.git
# Copy this skill to your global Antigravity skills folder
cp -r felo-skills/felo-search ~/.gemini/antigravity/skills/Installs to ~/.gemini/antigravity/skills/ — available across all your projects
Method 2 · Agent prompt
Let the agent install it for you
Paste this prompt directly into Antigravity. The agent clones the repo and copies the skill automatically.
Paste into Antigravity
Install https://github.com/Felo-Inc/felo-skills into my global Antigravity skills directory.
The agent handles cloning, copying, and directory setup — no terminal needed
1
Copy the skill folder
Clone the Felo skills repo and copy felo-search into .agent/skills/ (shared with your team via Git) or ~/.gemini/antigravity/skills/ (personal, available across all projects).
2
Set your Felo API key
Add FELO_API_KEY to your environment. The skill's SKILL.md description tells the Agent Manager when to activate it — no further setup needed.
3
Let the agent trigger it
Work normally in Antigravity. When your agent encounters a task involving current pricing, release notes, or live documentation, it loads felo-search automatically and returns a cited answer inline.
No configuration needed. The SKILL.md file inside the skill folder tells Antigravity's Agent Manager when to activate it. Once the folder is in place, the agent routes to the skill automatically based on your prompt.
FAQ
Felo Search in Google Antigravity — FAQ
Yes. The SKILL.md description field acts as a semantic trigger. When your agent's task involves current pricing, release notes, API changes, or live documentation, the Agent Manager loads felo-search on demand — you don't invoke it manually.
Close Gemini 3's knowledge gap with live web search
Install felo-search as an Antigravity skill and let the Agent Manager pull current, cited answers whenever your task needs the live web.
One API key. Drop the folder in .agent/skills/ and the whole team's Antigravity agents get live web search.
