Currently tool messages in Duo are large and blocky and contain multiple lines of hard to read JSON. When many tools are called as part of an agent cycle this can take up a substantial portion of the chat window, though users primarily care about the **output** of those tool uses. This will be especially important for Orbit, as Duo will be the primary surface through which Orbit is showcased and this will often mean multiple subsequent calls. We should dramatically scale back the appearance to allow the agent response to take center stage and provide a more easily scanned history. **Proposal** * Reduce all tool calls to a single line * Utilize human readable labels with standardized phrasing * Avoid extraneous details * Avoid referencing "MCP" for GitLab-native tools like semantic search or Orbit * Utilize more specific iconography, vs. defaulting most to `work-item-maintenance`
