Part of the Agent migration epic (roadmap: Weeks 3–4 → July). Owner: Jack.

Goal

Migrate the document classify/extract step off the raw Gemini seam onto a Pydantic AI agent.

Remaining call sites

  • backend/routes/documents.py:150 — call_gemini_json(prompt, model=MODEL_LITE)
  • backend/routes/documents.py:225 — call_gemini_json(prompt)

Notes

Acceptance

  • documents.py no longer imports/calls call_gemini_json; classification/extraction runs through the agent.
  • Existing document tests pass; add coverage for the agent path in backend/tests/.

                Part of the Agent migration epic (roadmap: Weeks 3–4 → July). Owner: Jack.
                Goal
                Migrate the document classify/extract step off the raw Gemini seam onto a Pydantic AI agent.
                Remaining call sites
                • backend/routes/documents.py:150 — call_gemini_json(prompt, model=MODEL_LITE)
                • backend/routes/documents.py:225 — call_gemini_json(prompt)
                Notes
                Acceptance
                • documents.py no longer imports/calls call_gemini_json; classification/extraction runs through the agent.
                • Existing document tests pass; add coverage for the agent path in backend/tests/.
