v0.5.0 — Introducing Subagents: Parallel AI Power

Highlights

  • Meet Subagents: The main AI can now spin up independent, parallel agents to research your codebase or execute complex, multi-step tasks in the background
  • Real-time visibility: Watch the subagents stream their thoughts and use tools live in the chat, keeping you fully in the loop
  • Fast and comprehensive: The new 'Explore' subagent rapidly searches, greps, and reads your files, handing off a neat summary back to the main chat
  • No more context overload: Deep-dive investigations happen in their own thread, keeping the main conversation clean and focused on building your game

Changes

Added
  • Subagent Architecture: The orchestrator AI can now delegate tasks to specialized, background AI agents
  • Explore Subagent: A fast, read-only agent built for rapid codebase discovery using ripgrep and file system tools
  • General Purpose Subagent: A fully capable agent that inherits the orchestrator's intelligence for making complex edits autonomously
Improved
  • UI Chat Experience: Subagent activity streams live as a beautifully interleaved transcript of thoughts and tools, ending with a clear summary report
Fixed
  • File Reading Reliability: Hardened the bridge between Summer Engine and the AI so it perfectly reads the exact file requested, even if you are actively working in another tab
