Investigate memory leaks from V8 heap snapshots (.heapsnapshot files). This skill starts when snapshots already exist: either the user provided them, DevTools exported them, or another workflow produced them. Use the helpers here to compare snapshots, group object deltas, and trace retainer paths.
Heap Snapshot Analysis is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/heap-snapshot-analysis/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when given .heapsnapshot files, asked to compare before/after snapshots, asked to find what retains objects, or investigating why objects survive GC.
The Heap Snapshot Analysis Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 146,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
