Unclear What consumes this added tools value and what effect it has is not stated.
What
When Claude Code forks a subagent (a separate Claude instance spun up to handle part of a task), the call that builds its context now includes tools: e.options.tools, passing along the set of tools the subagent has available.
Why
This makes the subagent's available tools visible to the context-building step, which likely improves how context is assembled around what that subagent can actually do.
