Tadpole is a from-scratch agent in 3,500 lines of Python, with LoRA adapters that teach Qwen3-4B tool use
Shown on HN Oct 31 under MIT, the framework-free agent handles files, shell, web search and session compaction from a terminal or Telegram, on any OpenAI-compatible API or a local Qwen3-4B, and its repo logs each build stage with tests and measurements. Its released adapters lift Qwen3-4B from 0.419 to 0.774 pass@1 on held-out task types, but that's the author's own 140-task benchmark measured only inside Tadpole's harness (adapter).
