 Agent APIPresets
 Prompt caching for presetsAgent API presets now use stable prompt cache keys automatically, allowing independent requests with the same preset to reuse the shared prompt prefix (system prompt and tool definitions). No request changes are required, and an explicit prompt_cache_key still overrides the preset default. This can reduce costs by about 5% for applications that use presets frequently, depending on cache utilization. The current preset values include each key for frozen configurations.
