Proposed fix: [Anthropic SDK tool runner compaction] 'Params.Compaction cannot be set on a tool runner' / 'messages were changed while the conversation was being compacted'
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Leave Params.Compaction unset; call runner.CompactBeforeNextTurn(config) when a threshold is reached; modify messages only after the compaction response is read; remove compaction edits from context_management first.
Option: Use CompactBeforeNextTurn [evidence: official_recommended_action]
Steps:
1. runner.CompactBeforeNextTurn(anthropic.BetaCompactionConfigUnionParam{})
2. don't set Params.Compaction or a compaction context_management edit
Expected: Runner compacts once and continues
