via “skill system for composable agent capabilities”

Workspace template + MCP server for Claude Code, Codex CLI, Cursor & Windsurf. Multi-agent knowledge engine (ag-refresh / ag-ask) that turns any codebase into a queryable AI assistant.

Unique: Provides a skill system where reusable capabilities (code review, testing, documentation) are defined as composable modules that can be combined to create specialized agents. Skills encapsulate tool sets, prompts, and execution patterns, enabling rapid agent specialization without code duplication. Skills can be enabled/disabled per agent, allowing the same framework to support multiple use cases.

vs others: Unlike monolithic agent frameworks (which require code changes to add capabilities) or plugin systems (which require installation), Antigravity's skill system enables capabilities to be composed declaratively and enabled/disabled at runtime. This approach provides flexibility without requiring code changes or external dependencies.

via “skill composition and reuse across agents and workflows”

Claude Code learns from your corrections: self-correcting memory that compounds over 50+ sessions. Context engineering, parallel worktrees, agent teams, and 17 battle-tested skills.

Unique: Implements skills as first-class composable units with explicit dependencies and parameters rather than embedding logic in agent code. Skills are defined declaratively in config.json and can be reused across different agents and commands. Most agent frameworks (LangChain, AutoGen) embed tool logic in agent code; Pro Workflow's skill abstraction enables better code reuse and testability.

vs others: More modular than monolithic agent code because skills are independent and testable; more composable than tool libraries because skills can be combined into workflows without code changes.
