Architecture
Both Copilot Chat and Kilo Code share the same Istar Code agent definition:
- Copilot Chat uses @Istar-code for quick tasks, code explanations, inline edits
- Kilo Code uses the same agent for complex multi-step tasks with MCP orchestration
- Both use the same model routing and fallback chains
Quick start
# Automatic setup
.\scripts\byok-master.ps1
# Then in VS Code, type @istar-code in Copilot ChatContributors
