Gemini API tool-grounding workflow for coding assistants

Design a grounded coding assistant using Gemini API tools, explicit context retrieval, and deterministic response formatting.

Last reviewed Feb 25, 2026

Use case

Build a coding assistant that answers with grounded, source-linked recommendations.

Architecture

  1. Query intake
  2. Context retrieval (repo + docs)
  3. Tool execution (search, file reads, tests)
  4. Structured response with citations

Prompt contract

Require these output sections:

  • decision summary
  • referenced files
  • command evidence
  • confidence and risks

Validation checklist

  • every recommendation maps to a source
  • no invented file paths
  • no unverified runtime claims

Operational tips

  • cache retrieval for repeated prompts
  • separate planning from execution calls
  • keep tool budget and timeout limits explicit
