What problem does it solve?

It prevents performance regressions and correctness hazards in Solana RPC and streaming infrastructure where latency at p99 and validator stability are critical.

Core Features & Use Cases

• Hot-path performance review: flags allocations, lock contention, async correctness issues, and missing backpressure patterns in request/message handling code.
• gRPC streaming and subscription rigor: validates bounded buffers, flow-control behavior under slow clients, and lag handling to avoid silent memory blowups.
• Solana-specific correctness safeguards: checks compute budgeting, account discriminator and owner validation, pagination/timeouts, and common Solana gotchas like lamports vs SOL and slot vs block height.
• Geyser plugin safety: enforces panic containment, bounded handoff queues, and memory-budget awareness to avoid validator-level instability.

Quick Start

Use this skill to review a PR diff that touches Solana RPC method handlers, gRPC streaming code, or Geyser plugin callbacks for perf risk, backpressure behavior, and validator safety.
