Why does the skill emphasize multiple heap dumps?

A single dump only shows a snapshot of memory at one point in time; comparing multiple dumps is essential to establish a trend and prove that memory is actually leaking rather than just being temporarily occupied.

How does this skill help identify memory leaks?

It provides a systematic 7-step process including baseline establishment, heap dump analysis, and tracing retention paths back to GC roots to find the specific code maintaining unnecessary references.

Which languages and platforms are supported?

The skill is grounded in cross-platform patterns applicable to any garbage-collected language, with specific guidance for Java, Node.js, and browser-based JavaScript.

Can Claude actually fix the leak for me?

Yes, once the retention path and culprit code are identified, Claude can use this skill to suggest and implement the necessary code changes, such as removing references or ensuring proper cleanup in listener subscriptions.

分析与监控

Identifies and resolves application memory leaks by performing systematic heap dump analysis and reference tracing.

This skill provides a structured framework for diagnosing performance degradation caused by memory leaks across various environments like Java, JavaScript, and Node.js. It guides Claude through a rigorous process of establishing memory baselines, capturing heap snapshots at peak usage, and tracing retention paths back to Garbage Collection (GC) roots. By applying industry-standard patterns and avoiding common pitfalls like misattributing issues to the garbage collector or overlooking global state, it helps developers pinpoint exactly which references are preventing memory from being reclaimed, ensuring long-term application stability.
