Full changelog

Fixed

  • Critical: .env path resolution — auto-route hook used 3 parent directories (resolving to src/.env instead of project root). Now uses Path.cwd() as primary lookup + 4 parents as fallback. Without this fix, OLLAMA_BUDGET_MODELS, LLM_ROUTER_CLAUDE_SUBSCRIPTION, and API keys were invisible to the hook.
  • Echo rendering — routed responses now render as normal black text in Claude Code CLI instead of warning-styled orange text. Uses contextForAgent (same priority as MANDATORY ROUTE) instead of additionalContext (which Claude ignores when CLAUDE.md is loaded).
  • session-start.py — added os.getcwd() as first .env search path for consistency.

Changed

  • Default render mode changed from block to echo. Configurable via LLM_ROUTER_RENDER_MODE=block env var for zero-cost (warning-styled) display.
