Detailed Verification¶
#186: Layered Text-to-SQL Architecture¶
- Requirement: Define a 5-layer pipeline (Router -> Intent -> Table -> Prune -> SQL).
- Implementation: The architecture is fully defined in
docs/architecture/data-copilot-text-to-sql.md, including a Mermaid diagram of the layers and HITL checkpoints. - Reference:
roadmap.mdunder "🌟 Future Projects -> Data Copilot".
#187: MCP Tool/Data Standardization¶
- Requirement: Use MCP for data/tool access with free/cheap integration paths.
- Implementation:
docs/knowledge_base/patterns/data-copilot-mcp-tooling.mdprovides an integration matrix, 5 concrete examples (SQL, Docs, KPI, HA API, Metadata), and a migration path. - Reference:
roadmap.mdunder "🌟 Future Projects -> Data Copilot".
#188: Agentic RAG + Hybrid Retrieval¶
- Requirement: Pattern for diagnostic analytics using SQL + Docs.
- Implementation:
docs/knowledge_base/patterns/data-copilot-agentic-rag.mddefines the agentic planner logic, a hybrid workflow diagram, and includes a root-cause investigation example ("Why did metric X drop?"). - Reference:
roadmap.mdunder "🌟 Future Projects -> Data Copilot".
#189: SQL Validation & Repair Guardrails¶
- Requirement: Safety rules, syntactic/semantic validation, and repair loops.
- Implementation:
docs/playbooks/data-copilot-sql-validation.mdincludes a 4-stage pipeline, a policy checklist (row limits, no mutations, etc.), and a self-correction logic definition. - Reference:
roadmap.mdunder "🌟 Future Projects -> Data Copilot".
#190: Answer Synthesis Schema¶
- Requirement: Standardized output including sources, confidence, and actions.
- Implementation:
docs/reference-implementations/data-copilot/answer-synthesis-schema.mdprovides a Pydantic schema (SynthesisResponse), a prompt contract, and two detailed example outputs (lookup and diagnosis). - Reference:
roadmap.mdunder "🌟 Future Projects -> Data Copilot".
Conclusion¶
Issues #186, #187, #188, #189, and #190 are considered Closed/Complete. The requested architectural patterns and documentation have been merged into the canonical repository structure.
