Summary

Essential reference guide for ADK agent development, covering spec-driven workflow, code preservation rules, and operational best practices.

  • Read DESIGN_SPEC.md first as your primary source of truth; all implementation decisions must align with it
  • Follow four mandatory phases: understand spec, build and implement, evaluate (using /adk-eval-guide), and deploy with human approval
  • Preserve all unrelated code when making modifications; only alter explicitly targeted segments and never change model names unless requested
  • Use Gemini 3 series models (gemini-3-flash-preview, gemini-3-pro-preview) for new agents; fix location issues (not model names) when encountering 404 errors
  • Stop immediately after three consecutive identical errors; fix root causes (tool bugs, state conflicts, location mismatches) before retrying operations

ADK Development Workflow & Guidelines

Session Continuity

If this is a long session, re-read the relevant skill before each phase — /adk-cheatsheet before writing code, /adk-eval-guide before running evals, /adk-deploy-guide before deploying, /adk-scaffold before scaffolding. Context compaction may have dropped earlier skill content.


DESIGN_SPEC.md — Your Primary Reference

IMPORTANT: If DESIGN_SPEC.md exists in this project, it is your primary source of truth.

Read it FIRST to understand:

  • Functional requirements and capabilities
  • Success criteria and quality thresholds
  • Agent behavior constraints
