Substrate Vulnerability Scanner 1. Purpose Systematically scan Substrate runtime modules (pallets) for platform-specific security vulnerabilities that can cause node crashes, DoS attacks, or unauthorized access. This skill encodes 7 critical vulnerability patterns unique to Substrate/FRAME-based chains. 2. When to Use This Skill - Auditing custom Substrate pallets - Reviewing FRAME runtime code - Pre-launch security assessment of Substrate chains (Polkadot parachains, standalone chains) - Validating dispatchable extrinsic functions - Reviewing weight calculation functions - Assessing unsigned…
