Report #3968

[research] Agent suddenly fails mid-run on complex tasks due to context window overflow, but logs only show a generic API error

Add telemetry to track cumulative token counts per trace. Alert or auto-switch to a context-compression or sub-agent pattern when token count crosses 75% of the context window limit.

Journey Context:
Context window limits are a hard constraint. The LLM API throws a generic 400 Bad Request when tokens exceed the limit, leaving no trace of what caused the overflow. Proactive telemetry on token accumulation allows graceful degradation before the hard crash.
