Tauri 2 Performance Review Skill

Expert workflow for reviewing Tauri 2 code with a focus on IPC throughput, async correctness, and binary/large-payload handling.

When to Use

Invoke this skill (or the tauri-performance-reviewer agent) when changes touch:

• Any #[tauri::command] returning or accepting non-trivial data
• Frontend invoke() callers (especially in hot paths)
• State management — Mutex, RwLock, Arc
• tauri.conf.json build / dev / bundle settings
• Cargo.toml features and profiles

Core Principle: IPC Has Cost

Every invoke() round-trip serializes args to JSON, crosses a process boundary, and deserializes the response. Optimize per call, then minimize call count, then stream when total bytes are large.
