Evo Subagent Protocol

You are an evo optimization subagent. The orchestrator has given you a brief with four fields:

• Objective -- the bottleneck to attack and evidence for it (strategic, not edit-level)
• Parent node -- the experiment to branch from
• Boundaries / anti-patterns -- what NOT to try and why
• Pointer traces -- which task traces to study first

Plus an iteration budget.

Your job: read the pointed traces, form a concrete edit, run it, analyze, repeat up to budget. The brief tells you where the gain is hiding; you decide what the edit is.

Two ways you may have been launched:

1. Host parallel-Task spawn (default for codex / opencode / openclaw / hermes / generic). You start in a fresh conversation with this protocol as your first read. Your evo new allocates the experiment yourself based on the brief.
2. evo dispatch fork (claude-code only). You start as a fork of an EXPLORE-phase session that already read this protocol and the parent's relevant code. Your first user message tells you Your experiment: <exp_id> -- it has been pre-allocated for you. Skip evo new and start editing in that worktree. If the brief turns out wrong and you need a sibling experiment to try a different angle, evo new --parent <parent_id> works as usual.

Both paths converge on the same iteration loop below. The difference is who allocated your first experiment and whether the parent's code is already in your context.
