Show HN: Mole Is a Go Deep-Research Agent With a Hard Spend Ceiling and Quote-Level Verification
Mole, which hit 76 points on HN, is a single static Go binary (no runtime deps, SQLite storage) that decomposes a question, searches, extracts claims, verifies each against a literal source quote, surfaces contradictions, and returns a cited answer — under an enforced dollar or token budget rather than an open-ended agent loop. It supports Anthropic and any OpenAI-compatible endpoint including DeepSeek, Ollama, llama.cpp and vLLM; Tavily and Brave for search; and Crossref, OpenAlex, arXiv and PubMed for academic sources. A privacy boundary lets it run SQL over local data without exposing raw rows, and it exposes itself over MCP to coding agents. Apache-2.0, 151 stars, 173 commits.
