[agent\_craft] Multi-step agent loses the original user goal after several rounds of context compaction

Maintain an immutable 'intent block' at the top of the system prompt that is excluded from summarization/compaction. Only compress the execution history, never the original goal and constraints.

Journey Context:
As conversations grow, agents compact older messages into summaries. If the compaction algorithm summarizes the original user request, subtle constraints \('use Python 3.9', 'avoid external dependencies'\) are often dropped. By the 10th step, the agent is solving a generalized version of the problem. An untouchable intent block prevents goal drift.
