The Explore and Plan sub-agents now dynamically adapt their search instructions based on whether embedded search tools (bfs/ugrep) are available. When embedded tools are active, agents are instructed to use find and grep via Bash; otherwise they use the dedicated Glob and Grep tools. The Explore agent system prompt was also updated to say "search broadly when you don't know where something lives" instead of the previous more specific tool-referencing language.
Evidence
Dynamic search instructions in sub-agent prompts (search for "Use \find\ via")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
