Give Every Antigravity Agent Task a Grounded Knowledge Base

Antigravity's Agent Manager is powerful at planning and executing — but it starts each task with only what's in the context window. Felo LiveDoc adds a persistent retrieval layer: index your runbooks, internal APIs, and architecture docs once, and every agent task that touches those topics gets grounded answers from your actual source material, not Gemini 3's training memory.

Agent tasks that trigger felo-livedoc automatically

These are the prompts where Antigravity's Agent Manager routes to felo-livedoc — when the task needs internal team knowledge, not public web 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 01

Internal policy lookup

Agent task references internal documentation the team has indexed.

What's our current API rate limit policy for enterprise customers?
Scenario 02

Architecture and spec reference

Agent needs to check internal architecture docs before making a recommendation.

Does our current auth service support OAuth 2.0 PKCE flow?
Scenario 03

Runbook and process lookup

Agent task involves a recurring process that's documented in the team's runbooks.

What's the rollback procedure for a failed database migration?
How it works

What felo-livedoc adds to Antigravity

Six capabilities that give every agent task a persistent, grounded knowledge layer.

Persistent knowledge base

Team knowledge persists across agent sessions — not lost when context resets.

Semantic search over docs

Agent retrieves the most relevant knowledge chunk, not a keyword match.

Team-shared context

One LiveDoc, shared across all team members' Antigravity instances.

Live sync

Knowledge base updates propagate to all agents without reinstalling.

Source-linked answers

Every retrieved chunk includes its source document for agent verification.

SKILL.md auto-routing

Activated when the agent task references internal docs, specs, or team knowledge.

Installation

Three steps to a persistent knowledge base in Antigravity

Once installed, the Agent Manager triggers felo-livedoc automatically when a task needs retrieval from your indexed documents — no slash commands, no copy-paste.

Method 1 · Terminal

Install via command line

Clone the Felo skills repo and copy the skill into your global Antigravity skills directory.

Terminal
# 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-livedoc ~/.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-livedoc into .agent/skills/ to share it with your team via Git, or into ~/.gemini/antigravity/skills/ for personal use. The SKILL.md description tells the Agent Manager when to activate it.

2

Index your source documents

Point felo-livedoc at your runbooks, internal API docs, architecture decision records, or any reference material the team's agents should know. Indexing happens once; retrieval is available in every subsequent session.

3

Agents retrieve, not hallucinate

When an Antigravity agent task touches a topic covered in your LiveDoc, it retrieves the relevant passage and cites the source — instead of guessing from Gemini 3's training data.

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 LiveDoc in Google Antigravity — FAQ

The SKILL.md description field acts as a semantic trigger. When an agent task involves querying internal documentation, runbooks, or stored references, the Agent Manager loads felo-livedoc on demand and retrieves the relevant passages — you don't invoke it manually.

Ground every Antigravity agent task in your team's actual docs

Install felo-livedoc in .agent/skills/ and let the Agent Manager retrieve from your indexed knowledge base instead of guessing.

One API key covers every Felo skill in Google Antigravity. Build a knowledge base once and query it whenever your agent needs grounded answers.
