Let Antigravity Agents Read the Room on X Before They Ship
When Antigravity's Agent Manager is planning a launch, drafting a competitive brief, or researching a market, it needs to know what's actually being said on X right now — not what Gemini 3 learned months ago. Felo X Search activates automatically when the task involves social signals, returning structured post data, reply threads, and sentiment the agent can reason over.
How it works
Agent tasks that trigger felo-x-search automatically
These are the prompts where Antigravity's Agent Manager routes to felo-x-search — when the task needs live social signals, not training data.
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
Launch signal monitoring
Agent needs to gauge early reaction to a product launch before writing copy.
How is the Cursor 1.0 launch landing on X? Any complaints or praise?
Scenario 03
Competitor move tracking
Agent task involves monitoring what a competitor just announced.
What did Linear announce in the last 7 days and how is it being received?
How it works
What felo-x-search adds to Antigravity
Six live social intelligence capabilities that Gemini 3's training data can't provide.
Live X signal retrieval
Real-time posts, threads, and reactions — not cached training data.
Filtered by relevance
Returns signal, not noise. Ranked by engagement and recency.
Sentiment analysis
Agent gets a structured read on how a topic is landing on X right now.
Time-bounded queries
Search the last 24h, 7 days, or 30 days — agent controls the window.
Account monitoring
Track specific accounts or hashtags as part of a competitive research task.
SKILL.md auto-routing
Activated when the agent task involves social signals, launches, or public sentiment.

Installation
Three steps to live X intelligence inside Antigravity
Once installed, the Agent Manager triggers felo-x-search automatically when a task involves social signals, launch monitoring, or competitor chatter on X.
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-x-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 into .agent/skills/
Clone the Felo skills repo and copy felo-x-search into .agent/skills/ to share it with your team via Git. The SKILL.md description tells the Agent Manager to activate it for social research and launch monitoring tasks.
2
Set your Felo API key
Add FELO_API_KEY to your environment. No X API key needed — felo-x-search handles the data access layer so your agents can query X without managing separate credentials.
3
Agents monitor X as part of the workflow
When an Antigravity agent is building a launch plan or competitive brief, it pulls live X posts, reply threads, and sentiment data automatically — the social layer becomes part of the agent's reasoning, not a separate research step.
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 X Search in Google Antigravity — FAQ
When a task involves social signals — launch monitoring, competitor tracking, sentiment analysis, influencer discovery, or any research where what people are saying on X right now matters. The SKILL.md description matches these intents semantically.
Give Antigravity agents live social intelligence before they plan or ship
Install felo-x-search in .agent/skills/ and let the Agent Manager pull real X signals into launch plans, competitive briefs, and market research tasks.
One API key. Commit to .agent/skills/ and every agent task that needs social signals gets live X data automatically.
