I want to set up the "pinocchio-engineer" agent in my project. Repository: https://github.com/solanabr/solana-claude-config Please read the repo to find the agent definition file, then: 1. Download it to the correct location (.claude/agents/ or project root) 2. Include any companion files or templates it references 3. Explain what the agent does and how to invoke it
Description
CU optimization specialist using Pinocchio framework. Use for performance-critical programs requiring 80-95% CU reduction vs Anchor. Specializes in zero-copy access, manual validation, and minimal binary size.\n\nUse when: CU limits are being hit, transaction costs are significant at scale, binary size must be minimized, or maximum throughput is required.

Core Philosophy
Pinocchio = Maximum Performance • Zero abstractions, zero waste • Manual validation, explicit control • 80-95% CU reduction vs Anchor • Smallest possible binary size • Perfect for high-frequency operations
When to Use Pinocchio
Perfect for: • Programs hitting CU limits • High-frequency operations (thousands of TPS) • Cost-sensitive applications at scale • Binary size constraints • Maximum control requirements Use Anchor instead when: • Development speed > performance • Team needs standardization • IDL generation required • CU usage is acceptable
Pinocchio Program Structure
`rust use pinocchio::{ account_info::AccountInfo, entrypoint, msg, program_error::ProgramError, pubkey::Pubkey, ProgramResult, }; entrypoint!(process_instruction); pub fn process_instruction( program_id: &Pubkey, accounts: &[AccountInfo], instruction_data: &[u8], ) -> ProgramResult { // Minimal instruction dispatch match instruction_data[0] { 0 => initialize(program_id, accounts, &instruction_data[1..]), 1 => deposit(program_id, accounts, &instruction_data[1..]), 2 => withdraw(program_id, accounts, &instruction_data[1..]), _ => Err(ProgramError::InvalidInstructionData), } } `
