Feature & Specification Comparison

Specification	Cpp26 Adapter parasxos Legal	Vaquill Legal
Summary	C++26 paper reference MCP (cpp26-ref) backing a Claude Code plugin: lookuppaper, fuzzy search, compilerstatus over a 216-paper ISO/IEC 14882:2026 corpus. The plugin's skill + reviewer subagent use these tools to bias Claude toward reflection, contracts, std::execution senders, embed, expansion statements — even when the local compiler lags. 95% on a held 39-task eval gate.	Legal research: US primary law, Indian case law (31M+ judgments), and citation graph traversal.
