Load before the first heap_executeQuery call, whichever skill is driving the analysis: the schema of a Jeffrey heap-dump index (class, instance, outbound_ref, class_instance_field, string_content, gc_root, dominator, retained_size) and the traps that return a wrong answer without an error — the string table is the name pool, not the String contents; outbound_ref.field_id counts the whole field layout; retained sizes need the current tree.

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/'heap-sql' ] || [ -L ~/.agents/skills/'heap-sql' ]; then echo 'A skill folder named heap-sql 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 "$d" checkout --quiet 'b7fcdb7b36f8f188c3d9642fd8aabc46dc882b20' -- 'jeffrey-agent-plugin/skills/heap-sql' && mkdir -p ~/.agents/skills && cp -R "$d"/'jeffrey-agent-plugin/skills/heap-sql' ~/.agents/skills/'heap-sql' && 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-sql' ~/.claude/skills/'heap-sql' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
