 Build a new Codex MCP provider side‑by‑side with the existing Codex SDK provider. The new provider lives in `packages/server/src/server/agent/providers/codex-mcp-agent.ts` and is selected via a new provider id (e.g. `codex-mcp`). All testing is **E2E only** (no mocks/fakes). Use `/Users/moboudra/dev/voice-dev/.tmp/happy-cli/src/codex/` as reference for MCP + elicitation.
 
+## CRITICAL RULES - READ BEFORE EVERY TASK
+
+1. **NO VAGUE REPORTS**: Never say "test hung", "was interrupted", "failed locally" without:
+   - The EXACT error message or stack trace
+   - The SPECIFIC line of code causing the issue
+   - A concrete hypothesis for the root cause
+
+2. **NO SKIPPING/DISABLING TESTS**: Skipping tests, adding `.skip`, or "opt-in gating" is **NOT ACCEPTABLE**. Fix the actual problem. If a test hangs, find out WHY and fix the code, not the test.
+
+3. **NO WORKAROUNDS**: Adding timeouts, fallbacks, or "defensive" code that hides bugs is forbidden. The code must work correctly, not appear to work.
+
+4. **INVESTIGATE DEEPLY**: When something fails:
+   - Read the actual source code
+   - Add debug logging if needed
+   - Trace the exact execution path
+   - Find the ROOT CAUSE, not symptoms
+
+5. **BE SPECIFIC**: Every "Done" entry must include:
+   - What the actual problem was (specific)
+   - What code was changed (file:line)
+   - How you verified it works
