The multimodal-looker prompt described what to do but never told the model which tools are available. Smaller VL models (e.g. Qwen3-VL-8B) would try to call non-existent tools and enter an infinite loop emitting:
Model tried to call unavailable tool 'invalid'. Available tools: call_omo_agent, read.
Add a single sentence at the top of the prompt that explicitly enumerates the only allowed tools ('read' and 'call_omo_agent') and forbids calling any other tool. This matches the runtime allowlist enforced by createAgentToolAllowlist(["read"]).
Regression test asserts the prompt contains the available-tools enumeration so future prompt rewrites don't regress.
