Extend Antigravity's Agent Manager beyond Gemini 3

Extend Antigravity's Agent Manager With Skills Gemini 3 Doesn't Have

Antigravity's Agent Manager is a powerful planner — but it starts every task with only what Gemini 3 knows. Felo Skills add the missing layers: live web data, persistent team knowledge, page extraction, slide generation, video transcripts, social signals, and visual evidence. Drop a skill folder into .agent/skills/ and commit it to Git — the whole team's agents get the capability immediately.

What Gemini 3 can't do alone

The capability gaps Felo Skills close for Antigravity agents

Antigravity's Agent Manager is a strong planner, but Gemini 3 has a training cutoff, no persistent memory, and no output layer. Felo Skills drop into .agent/skills/ and fill those gaps — automatically triggered by the agent, not by you.

Live data Gemini 3 doesn't havefelo-search, felo-web-fetch, and felo-x-search give agents current pricing, release notes, documentation, and social signals — the information that changed after Gemini 3's training cutoff.

Finished deliverables, not just summariesfelo-slides, felo-content-to-slides, and felo-landingpage turn agent research into .pptx decks and live hosted pages — the Agent Manager ships outputs, not just plans.

Persistent knowledge across sessionsfelo-livedoc indexes your runbooks, internal APIs, and architecture docs once. Every agent task that touches those topics retrieves grounded answers instead of starting from scratch.

Felo Skills give Antigravity's Agent Manager the data layers and output tools it needs to complete real work — not just plan it.

Live data layer

Closes Gemini 3 gaps

felo-search, felo-web-fetch, and felo-x-search give Antigravity agents current pricing, release notes, documentation, and social signals — the information Gemini 3's training cutoff can't provide.

Knowledge layer

Persistent team memory

felo-livedoc indexes your runbooks, internal APIs, and architecture docs once. Every agent task that touches those topics retrieves grounded answers — not Gemini 3 guesses.

Output layer

Finished deliverables

felo-slides, felo-content-to-slides, and felo-landingpage turn agent research into .pptx decks and live hosted pages — the Agent Manager delivers outputs, not just summaries.

Install model

.agent/skills/ in Git

Drop a skill folder into .agent/skills/ and commit. Every developer's Antigravity instance picks it up automatically — no per-user setup, no configuration drift.

How teams usually expand Antigravity

How Antigravity teams usually layer in Felo Skills

Most teams start by closing the knowledge cutoff gap, then add persistent team memory, then add output generation. Each layer makes the Agent Manager more capable without changing how you work.

Start by closing the knowledge cutoff

The first gap most teams hit is Gemini 3's training cutoff. felo-search and felo-web-fetch give agents current pricing, release notes, and documentation — the information that changed after training.

Agents stop returning stale pricing and outdated API docs

Current information becomes part of every research task automatically

No slash commands — the Agent Manager triggers the skill when the task needs it

Then add persistent team knowledge

Once live data works, teams add felo-livedoc to index internal runbooks, architecture docs, and API references. Every agent that touches those topics retrieves grounded answers instead of guessing.

Index once, available to every agent on the team via .agent/skills/ in Git

Grounded answers from your actual docs, not Gemini 3 approximations

Works across sessions — knowledge persists beyond the context window

Then add output generation

The final layer is turning agent research into finished deliverables. felo-slides and felo-landingpage let the Agent Manager ship .pptx decks and live pages — not just summaries.

Agent tasks end with a real deliverable, not a markdown summary

Research-to-deck and research-to-page happen in one agent workflow

The Agent Manager becomes a production tool, not just a planner

Agent tasks that Felo Skills unlock in Google Antigravity

Each skill fills a specific gap in what Antigravity's Agent Manager can do without leaving the IDE. These are the workflows that become possible once the skill is in .agent/skills/.

Live research and pricing checks

When an agent task involves current pricing, release notes, API changes, or competitor moves, felo-search activates automatically and returns a cited answer the agent can act on.

Triggered when

Any prompt containing 'latest', 'current', 'compare pricing', or 'what changed in' — the Agent Manager routes to felo-search when Gemini 3's training data isn't enough.

What you get

Agents stop hallucinating stale pricing and release data. Current information becomes a reliable part of every research task.

What the agent does

Agent encounters a question about current information Gemini 3 can't answer reliably.
SKILL.md semantic match triggers felo-search automatically — no slash command needed.
Cited, structured answer returns inline so the agent continues the task without leaving the IDE.

Grounded answers from team knowledge

When an agent task touches internal documentation, runbooks, or architecture decisions, felo-livedoc retrieves the right passage from your team's indexed knowledge base instead of guessing.

Triggered when

Tasks involving internal APIs, onboarding docs, architecture decisions, or any knowledge your team has already written down but Gemini 3 has never seen.

What you get

Internal knowledge becomes a reliable retrieval layer for every agent that needs it, shared across the whole team via Git.

What the agent does

Team indexes runbooks, internal specs, and architecture docs into a named LiveDoc once.
Agent tasks that reference those topics trigger felo-livedoc via SKILL.md routing.
Grounded answer returns from the actual source — not a Gemini 3 approximation.

Research-to-deck in one agent task

When an agent task ends with a presentation or report, felo-slides turns the research output into a .pptx deck without the agent needing to switch tools or summarize into a different format.

Triggered when

Launch briefs, competitive analysis decks, stakeholder updates, and any agent task where the final deliverable is a slide deck rather than a markdown summary.

What you get

Agent tasks that used to end at 'here's a summary' now end at 'here's the deck'. The Agent Manager ships deliverables.

What the agent does

Agent completes the research phase using felo-search or felo-livedoc.
SKILL.md routes the output step to felo-slides when the task calls for a presentation.
Structured .pptx deck is generated and ready to share — the Agent Manager delivers a finished output, not a summary.

Questions teams ask before adding Felo Skills to Google Antigravity

A quick check on what Gemini 3 can't do alone, how the Agent Manager picks up skills automatically, and which gap to close first.

Do I need to invoke Felo Skills manually inside Antigravity?

No. The SKILL.md description field acts as a semantic trigger. When your agent's task matches the skill's description — current pricing, internal docs, slide output — the Agent Manager loads the skill automatically. You work normally and the skill activates when the task needs it.

Where should I put the skill folder — .agent/skills/ or ~/.gemini/antigravity/skills/?

Use .agent/skills/ when the whole team should have the skill — commit it to Git and every developer's Antigravity instance picks it up on next pull. Use ~/.gemini/antigravity/skills/ for personal skills that only apply to your own projects.

Which Felo Skill should Antigravity teams add first?

Most teams start with felo-search, because Gemini 3's training cutoff is the most common blocker — agents return stale pricing, outdated release notes, or wrong API docs. felo-search closes that gap immediately and the value is visible on the first agent task that needs current information.

How is felo-livedoc different from just putting docs in the agent's context?

Context window space is finite and resets every session. felo-livedoc indexes your docs once into a persistent knowledge base and retrieves only the relevant passages when the agent needs them. The whole team shares the same knowledge base via .agent/skills/ in Git — no per-session pasting required.
