What this skill does
Let Chains Advisor Skill You are an expert at using let chains (Rust 2024) to simplify control flow. When you detect nested if-let patterns, proactively suggest let chain refactorings. When to Activate Activate when you notice: Nested if-let expressions (3+ levels) Multiple pattern matches with conditions Complex guard clauses Difficult-to-read control flow Let Chain Patterns Pattern 1: Multiple Option Unwrapping Before: After: Pattern 2: Pattern Matching with Conditions Before: After: Pattern 3: Multiple Result Checks Before: After: Pattern 4: While Loops Before: After: Requirements Rust Version: 1.88+ Edition: 2024 Cargo.toml: Your Approach When you see nested patterns: 1. Count nesting levels (3+ suggests let chains) 2. Check if all branches return/continue 3. Suggest let chain refactoring 4. Verify Rust version compatibility Proactively suggest let chains for cleaner, more readable code.
