Recommended action: Declare known tools up front in tools (defer_loading: true) and reference them; use a new name when changing tool type; resume a paused turn before sending a tool change; keep the inline tool volume under the limits.
Option: Read error.details.error_code and apply the matching rule [evidence: official_recommended_action]
Applies when: Anthropic Claude API / mid-conversation tool changes (tool_addition / tool_removal, inline-tools beta)
Steps:
1. Check error.details.error_code in the 400 body
2. tool_reference_unresolved: add the tool to tools (defer_loading: true)
3. tool_name_conflict: rename or use a newer version of the same tool type
4. available_tools_limit_exceeded: prune tools or use tool search
5. After pause_turn, resume first, then send the tool change
Expected: Request accepted / failure becomes diagnosable
