Walkthrough

This PR removes the agent_id parameter from the lead-agent application. The backend replaces dynamic agent_id handling with a hardcoded RUNAGENT_ID constant, while the frontend removes agent_id from its state and API requests. The frontend also switches from hardcoded localhost URLs to relative paths, and the vite configuration enables port fallback for development.

Changes

Cohort / File(s)	Summary
Backend agent_id removal and RunAgent integration examples/lead-agent/backend-rust/src/main.rs	Introduces RUNAGENT_ID constant; changes ScoreLeadsRequest.agent_id and ScoreSingleRequest.agent_id from String to Option<String> with deprecation comments; removes agent_id validation; replaces request.agent_id with hardcoded RUNAGENT_ID in client initialization; adds candidate JSON normalization with debug logging; enhances RunAgent result logging with JSON parsing and fallback handling; expands CORS allowed origins to include port 5174 variants.
Frontend agent_id state and API changes examples/lead-agent/frontend/src/App.tsx	Removes RunAgent agent_id state, UI input field, and related help text from Configuration step; removes agent_id from API request payload; changes API endpoint from hardcoded localhost URL to relative path (/api/score-leads); simplifies Continue button disabled state logic to remove agentId dependency.
Development server configuration examples/lead-agent/frontend/vite.config.ts	Changes strictPort setting from true to false to enable automatic fallback to next available port on startup.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Agent_id API contract changes: Verify the transition from required String to optional Option<String> doesn't break existing clients; confirm deprecation comment is sufficient.
• Hardcoded RUNAGENT_ID approach: Ensure this architectural decision aligns with intended deployment model and security posture.
• Candidate normalization logic: Review JSON parsing robustness and edge cases for malformed candidates.
• CORS configuration changes: Verify port 5174 variants are correct and the expansion doesn't introduce unintended access.

Poem

🐰 Agent ID's gone, the config grows lean,
Constants now reign where variables had been!
No more localhost, just paths so divine,
Port fallback blooms—let the bunnies align! 🌸
