[synthesis] Agent loses goal orientation mid-task despite successful tool calls and no context overflow

Inject a compressed goal state reminder every N turns or before a tool call, rather than just appending to the context.

Journey Context:
Teams monitor token counts and tool call success rates. A 200-status tool call doesn't mean the agent used the output correctly. Semantic drift happens when the attention mechanism is dominated by recent, noisy tool outputs rather than the original goal. Combining context window management literature with observability data reveals that middle-of-the-window blindness causes agents to work on auto-pilot, executing tools that look relevant to recent text but are orthogonal to the original intent.
