What's wrong with this entry?
Spawn a background agent fork that inherits the full conversation context and executes a specific directive independently.
/fork <directive>- The fork receives the parent conversation's full history as read-only reference context
- Each fork executes ONE directive, then stops — it is not a continuation of the parent
- Fork prompts should be specific directives about what to do, not descriptions of the situation
- The fork agent name is auto-generated from the first few words of the directive
- Requires at least one conversation turn before forking (you'll see "Cannot fork before the first conversation turn" if attempted too early)
- Controlled by the
tengu_copper_foxfeature flag orCLAUDE_CODE_FORK_SUBAGENTenvironment variable
