 For a skill with `context: fork`, Claude Code follows the rules in [Run skills in a subagent](/docs/en/skills#run-skills-in-a-subagent) instead, whether or not fork mode is on.
 
-Background subagents run with a [smaller built-in tool set](#available-tools) than foreground subagents, except for conversation forks, and they surface every permission prompt in your main session. When you answer one of those prompts with a choice that lasts beyond that one tool call, such as "Yes, allow all edits during this session", Claude Code applies your answer to the whole session, including your main conversation.

 A background subagent's results reach Claude as a completion notification in a later turn. Claude waits for that notification before reporting the subagent's results, and if you ask about progress first, it reports that the subagent is still running. Before v2.1.211, Claude sometimes reported results for a background subagent that hadn't finished.
