Summary

AI summary

Wizard now detects running from zip, Windows version, Ollama PATH issues, model download failures, and fixes install scripts.

Full changelog

What's new

Onboarding — new user experience hardened end to end

  • Temp directory detection — if you run install.bat from inside the zip without extracting first, the wizard now catches it and tells you exactly what to do instead of silently writing config to a temp folder that gets deleted
  • Windows version check — catches Windows builds older than 19041 (pre-WSL2) before Docker install fails with a confusing error
  • Ollama PATH fix — after winget installs Ollama, the wizard now adds it to the current session PATH so it can actually launch it immediately without requiring a new terminal
  • Ollama not-starting fallback — if Ollama is installed but won't start, setup now exits with a clear message instead of continuing into silent model download failures
  • Model download failure detection — if a model pull fails, the wizard now reports it and stops instead of printing success and continuing
  • install.ps1 rewrite — complete rewrite using single-quoted strings throughout, eliminating the PowerShell parser crash that affected fresh Windows installs
  • install.bat elevation fix — path-with-spaces bug in the UAC re-launch fixed

README quick start rewritten for non-technical users

  • Primary actions are now double-click launch.bat / stop.bat — no terminal commands required
  • Docker restart instructions say "double-click install.bat again" instead of "run python"
  • Agent names removed — agents choose their own names, not hardcoded

CLAUDE.md added

Project context file loaded automatically by Claude Code at the start of every session. Contains project overview, agent roles, key files, invoke_claude protocol, release process, known bugs, and rules. Eliminates the need to re-explain the project at the start of each session.
