1.9.2

Long Claude sessions are now cheaper: Swival caches the conversation after the first reply on Anthropic, OpenRouter, Bedrock, and Vertex AI.

Claude models on Vertex AI now use prompt caching, and the Anthropic API caches tool definitions separately so sessions and subagents can reuse them.

When a file write, edit, or delete fails, Swival skips dependent tool calls sent after it in the same response.
