Context & Analysis

The update reflects the plugin's evolution to support OpenRouter's expanding model catalog, particularly reasoning models that require more sophisticated integration points. The move to OpenRouter's Responses API and the addition of server-side tools (Shell, WebFetch, WebSearch) suggests a shift toward enabling more complex, tool-augmented workflows without requiring users to manage separate infrastructure. By allowing tools to be toggled via command-line flags, the plugin maintains backward compatibility while letting advanced users compose more powerful agents.
