Master Dart Concurrency: Enhance AI Agent Skills with Async

Master Dart Concurrency: Enhance AI Agent Skills with Async

This skill is designed to facilitate the design and debugging of asynchronous infrastructures in Dart, focusing on explicit ownership, ordering, cancellation, and error propagation. The skill assists developers in managing concurrency efficiently using Future, Stream, isolates, and cancellation mechanisms, ensuring lifecycle-safe ownership and error-handling protocols.

What this skill does

• Identifies producers, consumers, and lifecycle owners to clarify ownership and ordering requirements.
• Uses 'Future' for obtaining a single result and 'Stream' for handling a sequence of asynchronous events over time.
• Manages cancellation of asynchronous tasks to prevent stale results from affecting newer state changes.
• Handles CPU-bound work using isolates while avoiding ordinary network I/O.
• Maintains stack trace integrity when dealing with error propagation across different asynchronous contexts.
• Advises on retry and timeout strategies based on idempotency and user intent.

Who it is for

This skill benefits developers and teams who utilize AI coding agents such as Claude Code, Cursor, and Codex, especially those needing to implement robust asynchronous handling in Dart applications.

Use cases

• Managing race conditions or leaks in complex asynchronous systems.
• Structuring CPU-bound background tasks requiring isolation without impacting UI responsiveness.
• Implementing fault-tolerant systems through explicit async ownership and error-handling strategies.
• Optimizing lifecycle management to guard state changes after asynchronous operations.

Technical details

• Utilizes Future and Stream for asynchronous programming in Dart.
• Employs isolates for effective CPU-bound processing.
• Incorporates robust cancellation mechanisms to prevent data inconsistency.
• Safeguards against outdated requests using sequencing or latest-wins logic.
