heap-snapshot-analysis
100 / 100 · Low risk
Fine to try.
Analyze V8 heap snapshots to investigate memory leaks and retention issues. Use when given .heapsnapshot files, asked to compare before/after snapshots, asked to find what retains objects, or investigating why objects survive GC. Provides snapshot parsing, comparison, retainer-path helpers, and scratchpad scripts.
What this skill can do
We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.
Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'heap-snapshot-analysis' ] || [ -L ~/.agents/skills/'heap-snapshot-analysis' ]; then echo 'A skill folder named heap-snapshot-analysis already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/posit-dev/positron' "$d" && git -C "$d" checkout --quiet '5d355d4cbe7e46087286c0d17f277c0d82fd2593' -- '.github/skills/heap-snapshot-analysis' && mkdir -p ~/.agents/skills && cp -R "$d"/'.github/skills/heap-snapshot-analysis' ~/.agents/skills/'heap-snapshot-analysis' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'heap-snapshot-analysis' ~/.claude/skills/'heap-snapshot-analysis' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
