Showcase

The showcase section is for proof-of-concept builds — agents and integrations the project ships specifically so readers can see ADK's contracts working in something more than a quickstart snippet.

• The Ask ADK Agent — an earlier in-browser docs-agent design (tool-less Llama-3.2-3B, synthetic RAG). End-to-end narrative of the pipeline (retrieval, citations, memory, the rejection-and-redo gate) and every choice behind it. The live agent in the floating Ask ADK launcher is now the more capable flagship; this remains a study of the patterns it inherits.
• Building the On-Device Batteries — tool-calling, reasoning, and multimodal on 360M–4B models in Node and the browser, no API. The build/test narrative: parser archaeology, the false greens and crashes, and the one wall (LiteRT is Gemma-only) we proved at the file-format level.
• Building the Dev Tools Battery — edit -> write -> lint --fix -> check as one plan, one tool call, one result, with write mid-chain. What that costs once you refuse to lie about any of it: a pipe grammar that provably cannot carry code, a path translator that throws for every file you are about to create, a filesystem contract with no delete, and a write path that is not atomic and says so.
• Punching Above Its Weights — the live site agent (the floating Ask ADK launcher): Gemma-4 (2B/4B) on WebGPU, a real tool loop, a planner book-end, a cascade of deterministic gates, and SQLite persistence, all made to behave like it has adult supervision. No API, no backend.
  • The Agent, In Full — the complete source, all 31 files, browsable and fetchable whole for whoever wants to port it.
