Agent SDK v0.10.5

This release changes default tool-calling behavior on supported models and improves how summary-only context preserves important conversation state. It does not require a migration, but you should verify agents that use tools or rely on summary_only context after upgrading.

Breaking changes

• Strict tool calling is now the default on supported models (#12)
  Review and test any agent that uses tools on supported models, and update tool schemas or handling if your current flow depends on non-strict behavior.

Highlights

• Enable strict tool calling by default on supported models (#12)
  Agents using tools now default to stricter tool schema handling on supported endpoints. This can change runtime behavior for existing tool-enabled flows, so validate your tool definitions and responses after upgrading.
• Preserve instructions and tool results in summary_only context (#11)
  Summary-only context now keeps the first user instruction, tool results, and unsummarized turns. This helps agents retain important guidance and recent execution context instead of losing it during summarization.

Upgrade notes

No migration is required for this upgrade. Replace the image or package as usual, then test agents that use tools on supported models and any workflows that rely on summary_only context to confirm behavior matches your expectations.
