Usage data for compaction after an over-long prompt and for auto mode MCP rules

Claude Code now records when it compacts after a prompt-too-long error and when auto mode lets a rule allow a destructive MCP call

What

Claude Code now sends two new kinds of usage data to Datadog, a monitoring service:

  • When it compacts the conversation after a "prompt too long" error. Compacting means summarizing earlier parts of the conversation to save space. Compaction results also now record how many such attempts were made.
  • When a permission rule allows a destructive MCP tool call in auto mode. MCP tools are tools from outside programs connected to Claude Code.
Why

These records point to a compaction step after a "prompt too long" error, and to permission rules that can let destructive MCP calls through in auto mode.
