Report #36629

[agent\_craft] Agent uses a sliding window or simple truncation on the conversation history, accidentally cutting off the original user goal

Implement priority-based context management. The system prompt and the initial user task must have 'pinned' priority \(never truncated\). Older tool outputs and exploratory steps should be truncated or summarized first.

Journey Context:
When the context hits the limit, naive APIs or frameworks just chop off the oldest messages. If the system prompt was message 0, it stays, but if the user's detailed task was message 1, it gets chopped. The agent then forgets what it was doing and hallucinates a new goal. Pinning the task and summarizing the journey is essential.
