Research conducted on modern AI coding assistants (Cursor, GitHub Copilot, Cline,
Aider, Windsurf, Replit Agent) to understand architecture patterns, context management,
code editing workflows, and tool use protocols.
Key Decision: Pivoted from building full CLI (40-50h) to validation-driven MCP-first
approach (10-15h). Build 5 core CODEX MCP tools that work with ANY coding assistant,
validate adoption over 2-4 weeks, then decide on full CLI if demand proven.
Files:
- research/ai-systems/modern-coding-assistants-architecture.md (comprehensive research)
- research/ai-systems/codex-coding-assistant-implementation-plan.md (original CLI plan, preserved)
- research/ai-systems/codex-mcp-tools-implementation-plan.md (approved MCP-first plan)
- ideas/registry.json (updated with approved MCP tools proposal)
Architech Validation: APPROVED with pivot to MCP-first approach
Human Decision: Approved (pragmatic validation-driven development)
Next: Begin Phase 1 implementation (10-15 hours, 5 core MCP tools)
