`/heapdump`

slash never mined documented JSON

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.

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; type it in full. See what to do with the output

First cited

No release's published evidence quotes this name. The ledger indexes the Evidence lines of every changelog on this site, so this says nobody here has ever quoted it; it says nothing about how old the name is.

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.

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.
