50+ builtin skills

Skill Forge

SOTA

Describe what you want. The forge researches SOTA techniques, scans literature, and synthesizes a comprehensive skill.

Research-driven synthesis

Composition Studio

Phase 1

Chain skills into DAG pipelines with dependencies. Track manifest versions and monitor execution health.

Compose • Version • Measure

Self-Improvement Loop

Phase 2

Episodic memory, failure diagnosis, and curriculum learning. Let agents improve themselves from past execution logs.

Voyager-style learning

Trust & Coordination

Phase 3

Marketplace trust verification, multi-agent coordination with shared scratchpad, and DSL compilation for parallelization.

Trust • Coordination • Compilation

Apex Agents

Phase 4

Self-authoring constitution amendments, privacy-preserving skill distillation, and LLM-as-judge verification.

Self-authoring • Distillation • Verification

Manifest Export

New

Export skill manifests as JSON or Markdown documents. Share configurations, back up agents, or migrate skills across workspaces.

JSON • Markdown • Clipboard

Antigravity MCP

Runtime

Model Context Protocol runtime for autonomous agents. Connect agents, delegate tasks, and manage multi-agent workflows with unified coordination.

MCP • Delegation • Orchestration

Coder

Generation

Leverage Gemini's code generation to synthesize skills from natural language specifications. Instant implementation from prompts.

Code Generation • LLM-powered

Manifest Registry

Inspect

View and manage all installed skill manifests. Check dependencies, inspect configuration, and track versions across your ecosystem.

Registry • Inspection • Management

Skills Manifest

Skills Manifest Registry

Reusable, parameterized skill plans

Each skill is a named, parameterized plan template with an input schema and an ordered set of tool steps over the Antigravity tool surface registry. 7 builtin skills ship out of the box — plus marketplace and user-authored manifests.

Manifest schema

Typed input schema, tool surfaces, plan template, version, source (builtin / marketplace / custom).

Plan compilation

Resolves a manifest against inputs into an ordered, executable step plan.

Export and install

Export manifests as JSON or Markdown. Install one-click into your agents.

Marketplace

Skills Marketplace

Discover, install, and share skills

Four ways skills enter your agent's library: recommended from usage patterns, installed from a manifest URL, forged locally, or distilled from cross-user execution data. All flow through the same manifest schema.

Recommended for you

Personalized suggestions powered by your run history and the `skillRecommender` backend, surfaced via the Recommended Skills feed.

skillRecommender

Install from URL

Paste any hosted manifest URL (JSON) to import a skill from another workspace, a public catalog, or a GitHub gist.

UrlInstallBar

Forge & publish

Author skills in the Forge Studio, version them, and export portable JSON or Markdown manifests for distribution.

SkillForgeStudio

Cross-user distillation

Phase 4 distills successful run patterns across users into new, anonymized skills via `skillDistillation`.

skillDistillation

Every channel emits the same manifest shape — skill_id, input_schema, plan_template, version.

Infrastructure

Skills Infrastructure

The 5-layer skill stack

Every skill flows top-down through these five backend layers: authoring → compilation → execution → verification → distillation. Each layer is a dedicated backend function with its own studio.

01Authoring

Skill Forge & Self-Authoring

Forge skills manually or let an agent author one from a goal description.

agentSelfAuthoragentCoordinator

02Compilation

DSL Compiler

Compile a manifest's plan_template into an optimized execution DAG with parallel groups and cache keys.

skillDSLCompiler

03Execution

Cascade Executor

Runs the compiled plan with retry, fallback, and step-level telemetry. Streams artifacts back as steps complete.

skillCascadeExecutor

04Verification

Trust Verifier

Sandbox + critic ensemble produces a 0..1 trust score per skill, with verdicts: trusted / caution / untrusted.

skillTrustVerifierverifierSkill

05Distillation

Pattern Distillation

Mines successful execution logs to propose new skills. Cross-user patterns are anonymized before lifting.

Code Generation

Gemini 3.5 Flash Coder

Code generation with Node preview & agent chains

Generate, fix, refactor, or review code. Run output live in a Node.js sandbox. Compose architect, implementer, reviewer, and integrator sub-agents for larger builds.

Single-shot coding

Generate, fix, explain, refactor, or review across 10 languages.

Node.js live preview

Browser-sandboxed runtime with console, process, and require for path, util, crypto.

Agent + sub-agent chain

Architect plans, implementer codes, reviewer audits, integrator finalizes.

Antigravity MCP

Managed agents over every Base44 surface

Google-style agent suite that orchestrates 29 tool surfaces across creative, decision, research, and utility families. Each surface maps to a real Base44 backend function and is exposed via the Model Context Protocol so Antigravity desktop or any MCP client can invoke them.

Agent roster and tasks

Spawn agents, compose plans, inspect artifacts, review desktop bridge activity.

MCP bridge

Single manifest exposes all tool surfaces to Antigravity desktop and in-app agents.

Skill registry

Browse, install, and chain skills directly from the agent console.

How it works

1. Browse

Explore the skill catalog. Filter by category, search by name, preview manifests.

2. Forge

Describe your need. The forge synthesizes a SOTA skill combining research, literature, and LLM reasoning.

3. Deploy

Install skills to your agents. Trigger them in tasks, monitor execution, iterate.
