Original Pull Request: https://github.com/anomalyco/opencode/pull/2835

State: closed
Merged: No

Summary

  • Drop prior assistant reasoning parts from history passed to providers (display-only), preventing OpenAI Responses API error: item of type 'reasoning' provided without required following item.
  • Filter aborted assistant messages with no contentful parts (text or completed/error tool results) so history never serializes to empty content, avoiding messages.N must have non-empty content.

Rationale

Interruptions (Ctrl-C) could leave an assistant turn with only step markers or partial tool scaffolding; combined with replaying reasoning chunks, subsequent calls errored and wedged the session. This patch makes history safe while preserving visible reasoning and contentful context.

Scope

  • smartypants: provider transform + message-v2 + prompt filter only.

Notes

  • Typecheck OK via turborepo; no API or configuration changes.
