Issue

Closes #9902

Type of change

  • Bug fix
  • New feature
  • Refactor / code improvement
  • Documentation

What does this PR do?

Handles context overflow errors by automatically triggering compaction instead of silently ignoring them. When a ContextOverflowError is caught, the code now sets needsCompaction = true to ensure the session can recover from context overflow without manual intervention.

Changes

  • Updated packages/opencode/src/session/processor.ts to set needsCompaction = true when a ContextOverflowError is caught
  • Previously this was a TODO comment that did nothing
  • Also fixed a TypeScript error in auth.ts that was causing typecheck failures

Why this works

The existing compaction logic already handles token overflow by compressing the conversation history. By triggering this same logic when an API returns a ContextOverflowError, we ensure the session automatically recovers rather than failing.

How did you verify my code works?

  • Code review: The fix follows the same pattern as the existing overflow detection at line 283
  • All tests pass (typecheck, unit, e2e)
