SDK Concepts

The Rust crate packages Pinocchio-specific knowledge and constraints so AI agents do not rely on stale training data or web results.

Core modules

• guard: signer, writable, owner, PDA, discriminator, and rent checks.
• schema: AccountSchema for zero-copy account layout contracts.
• dispatch: single-byte instruction dispatch with explicit error behavior.
• idioms: account parsing, CPI, PDA, events, architecture, and helpers.
• testing: litesvm and mollusk-svm testing references and helper assertions.
• anti_patterns: common Solana/Pinocchio vulnerabilities to review against.

Agent rules

Project guidance requires importing from geppetto::*, using guard::* for account access, implementing AccountSchema, and avoiding catch-all dispatch success.
