Analyses a heap dump held by a running Jeffrey Microscope — what is holding the memory, what is leaking, which class loader survived a redeploy, where the waste is — starting from the catalogue or from a .hprof file Jeffrey has not seen yet. Use whenever the user asks what is holding memory, why the heap keeps growing, why the JVM ran out of memory, what is leaking, or mentions retained size, a dominator tree, GC roots, a heap dump or an .hprof file.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'analyze-heap' ] || [ -L ~/.agents/skills/'analyze-heap' ]; then echo 'A skill folder named analyze-heap already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/petrbouda/jeffrey' "$d" && git -C "$d" checkout --quiet 'b7fcdb7b36f8f188c3d9642fd8aabc46dc882b20' -- 'jeffrey-agent-plugin/skills/analyze-heap' && mkdir -p ~/.agents/skills && cp -R "$d"/'jeffrey-agent-plugin/skills/analyze-heap' ~/.agents/skills/'analyze-heap' && 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/'analyze-heap' ~/.claude/skills/'analyze-heap' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
