Description

When the LLM context limit is exceeded, the raw API error message is being sent to the user through messaging channels (Telegram, etc.) instead of being handled gracefully.

Error seen by user

LLM request rejected: input length and max_tokens exceed context limit: 170636 + 34048 > 200000, decrease input length or max_tokens and try again

Expected behavior

These internal errors should be caught and either:

1. Auto-compact and retry (which exists but apparently doesn't always catch these)
2. Show a user-friendly message like "Session getting long, refreshing..." or just silently handle it

Environment

• Version: 2026.1.24-3
• Channel: Telegram
• Model: claude-opus-4-5

Notes

The release notes mention "auto-compact on context overflow prompt errors before failing" but this error is still reaching users. Seems like the error is thrown before the retry logic kicks in, or there's a code path that bypasses it.
