Report #1553

[agent\_craft] Agent runs out of context window mid-task, leading to truncated system prompts or catastrophic looping

Implement a strict context budget. Track token usage and trigger a compaction/summarization step before hitting the hard limit, ensuring the system prompt and recent scratchpad are preserved. Never let the API truncate the system prompt.

Journey Context:
Hitting the context limit causes the oldest tokens to be dropped, which usually means the system prompt \(the agent's core instructions\) is lost, causing it to break bad. Proactive compaction \(e.g., at 80% capacity\) allows the agent to intentionally choose what to keep \(instructions, current state\) and what to discard \(old tool outputs\), maintaining operational coherence.
