🛡️ Safe Solana Builder The first Claude skill for writing production-grade, security-first Solana programs. Built by a Solana security researcher, for Solana developers — so your code arrives at audit already hardened. What Is This? Safe Solana Builder is a security skill system you can load into AI coding workflows (Claude / Cursor) so Frank Castle's Solana security knowledge is applied before writing a single line of code. This is not a prompt. It is a layered reference architecture that forces Claude to: Select the right framework (Anchor, Native Rust, or Pinocchio) and load the matching security ruleset Choose a testing approach (LiteSVM or framework default) and load the matching test patterns Assess the program's risk level (🟢 Low / 🟡 Medium / 🔴 Critical) before touching the keyboard Apply a curated set of security rules drawn from real audit findings — CPIs, PDAs, account validation, arithmetic, Token-2022, and more Deliver a full project scaffold — not just Generate a test file skeleton with security edge cases pre-identified Output a security checklist documenting every rule applied and every known limitation Every program this skill produces has a first layer of...

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
