final report only

- Uses the other tools' quota, or your GPU, instead of Claude's.

- Same Agentcall as a normal subagent.

- Only the final report comes back.

- You can jump in anytime: tmux attach -t bridge-<harness>-<name>

One entry in bridge/params.json plus agents/<harness>.md.

Proof of concept. Tested: pi + local gemma. Plugin name is multiharness-delegation (claude-* names are reserved).
