What problem does it solve? Understanding Solana's internals — the SVM execution engine, account model, consensus, and validator economics — requires digging through scattered blog posts, SIMD proposals, and Agave/Firedancer source code. This Skill centralizes that research by routing architecture questions to the right reference material and fetching authoritative content via the Helius MCP server. ## Core Features & Use Cases - Topic Routing: Maps questions to ten curated reference files covering compilation, program deployment, execution, accounts, transactions, consensus, validators, data layer, development frameworks, and Token-2022. - Live Source Fetching: Uses Helius MCP tools (fetchHeliusBlog, getSIMD, readSolanaSourceFile, searchSolanaDocs) to pull current blog posts, SIMD proposals, and Agave source files, with citations in every answer. - Use Case: A developer asks how local fee markets prevent one congested token swap from raising fees network-wide. The Skill reads references/transactions.md, fetches the relevant Helius blog post, and explains per-account fee contention with a cited source. ## Quick Start Ask how Solana's Sealevel runtime executes transactions in parallel and why upfront account declarations make it possible.
