DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Reference / Slash commands

/heapdump

A Claude Code slash command, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

What it is

Write a JavaScript heap snapshot and a memory breakdown to ~/Desktop, or your home directory on Linux without a Desktop folder, for diagnosing high memory usage. Attach only the -diagnostics.json file when reporting a memory issue; the .heapsnapshot contains your full conversation and credentials, so don't share it. [Hidden from the command menu](#how-the-command-menu-matches-what-you-type); type it in full. See [what to do with the output](/docs/en/troubleshooting#high-cpu-or-memory-usage)

Presence across releases

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Changelog entries naming it

  1. v2.1.248Local file paths and error text withheld from remote sessions

    /heapdump and restart no longer send local paths or error text to remote sessions.

Documentation pages

A reference table page is one whose own table defines this name, and it is where the description above came from. A page that mentions it carries the name somewhere in its text and may say nothing about it at all. Every page carrying it.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the slash command does. All slash commands.
