Agents that have a tool contract: natural language to SQL with schema checks and a self-correction loop, plus early evaluation of on-device agent models.

## What I build

- Natural-language interfaces that compile to a constrained action, such as a read-only SQL query, instead of an open-ended chat reply.
- Evaluation of small on-device models (including FunctionGemma) for agentic workflows on IoT hardware. That evaluation is in progress, not a shipped product claim.

## Architecture

- The SQL agent treats query generation as a compile step. Pydantic checks the shape of the output before anything runs.
- If execution fails or returns an empty result, the error goes back into the context and the agent retries. That reflection loop is the reliability mechanism.
- Permissions stay read-only. The prompt receives only the tables relevant to the question, which keeps the schema small.
- Responses are structured JSON: the SQL and the interpreted rows, so a dashboard can render them without parsing prose.

## Production constraints

- Hallucinated table names and SQL injection are the same class of bug. Schema validation plus a read-only role is the control.
- Stuffing the full database catalog into the prompt raises latency and token cost. The agent selects tables from the user's intent first.

## Stack

Python, LangChain, Pydantic, PostgreSQL, OpenAI, Gemini

## Tradeoffs

- A compile-and-check agent is slower than one-shot SQL generation and much safer to put in front of a real database.
- On-device models such as FunctionGemma are being evaluated for IoT because a cloud round-trip is the wrong dependency for that hardware. They are not a replacement for the hosted SQL agent.

## Questions

### What agent has he built that is more than a chatbot?

The SQL AI Agent turns a question into validated, read-only SQL, retries when execution fails, and returns structured JSON.

### Is FunctionGemma in production?

No. It is under evaluation for agentic workflows on IoT hardware, alongside quantized PyTorch and Ollama prototypes.
