Conversation
The model sometimes claims tools like mcp_invoke_tool or mcp_get_service_details don't exist — even when they're in the tool list — producing false denial text in follow-up passes. Now checks the follow-up result against CapabilityDenialRegex and discards it rather than appending misinformation to the user's response.

Summary
The model sometimes hallucinates that tools like
mcp_invoke_toolormcp_get_service_detailsdon't exist — even when they're right there in the 40-tool list. When this happens on a follow-up pass, the false denial gets appended to an otherwise good response.Now checks the follow-up result against
CapabilityDenialRegexand silently discards it rather than showing the user misinformation like "the runtime does not expose mcp_get_service_details."Test plan
