What problem does it solve?

This skill helps Solana developers model and audit account flows to ensure correct ownership, signers, rent handling, and deterministic PDAs, reducing runtime errors and security risks.

Core Features & Use Cases

• Ownership and signer validation: verify which accounts must be owned by which programs and which must sign.
• PDA seeds and bump planning: document seed patterns, bump derivation, and collision avoidance.
• CPI metas and account layout: design cross-program invocations with correct writable and signer flags and account order.
• Rent planning and lifecycle: ensure accounts remain rent-exempt as they grow or shrink.
• Use Case: auditing a program's initialization and state transitions for correctness and security.

Quick Start

Review an instruction set and map each involved account's owner, signer, writable, and seeds to produce a robust, auditable account plan.
