/subtask

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.

Spawn a forked subagent: a background subagent that inherits the full conversation and works on the task while you keep working. Its result returns to this conversation when it finishes. To copy the conversation into a separate background session instead, use /fork. Requires Claude Code v2.1.212 or later; on v2.1.161 through v2.1.211 this command is /fork. When agent view is turned off, /subtask isn't available and /fork keeps the forked-subagent behavior

Anthropic's own wording. Read off Commands, captured 2026-09-28.

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.

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.
