Recommended action: Add header Foundry-Features: AgentsOptimization=V2Preview; include system_prompt/tools/skills in optimization_config; start with builtin.task_adherence; pass --optimize-model gpt-5 or set optimization_model in eval.yaml; use exact deployment names.
Option: Send preview header and targets [evidence: official_recommended_action]
Steps:
1. Foundry-Features: AgentsOptimization=V2Preview
2. optimization_config with system_prompt
3. --optimize-model gpt-5
