📝 Walkthrough

Walkthrough

The CLAUDE context-window override CLAUDE_CODE_MAX_CONTEXT_TOKENS now applies to all user types when set to a valid positive integer. Streaming handling for stopReason === 'model_context_window_exceeded' now yields an assistant error including errorDetails: 'context_window_exceeded' alongside the existing max-output error fields.

Changes

Cohort / File(s)	Summary
Context Window Configuration src/utils/context.ts	Removed the process.env.USER_TYPE === 'ant' gate so CLAUDE_CODE_MAX_CONTEXT_TOKENS override applies universally when parsed as a positive integer.
Streaming Error Handling src/services/api/claude.ts	When streaming stops with model_context_window_exceeded, the yielded assistant error now includes errorDetails: 'context_window_exceeded' in addition to existing max-output error fields for clearer routing.

Poem

🐰🌱 I hopped through code to clear the gate,
A token window opened wide and late.
Streams now label why they cease,
A tidy hop toward calmer peace.
