Report #6992

[agent\_craft] Autonomous agent loops fail or degrade after many steps because the context window fills up with intermediate thinking and failed tool calls

Implement a context checkpoint mechanism. When context reaches 70-80% capacity, pause, extract the current goal and state into a compact scratchpad, clear the history, and resume with only the scratchpad and the original system prompt.

Journey Context:
Long autonomous runs \(e.g., resolving a complex bug\) generate massive logs of failed attempts. If left in context, the agent gets stuck in loops or hallucinates based on old errors. Clearing the context breaks the loop, but without a scratchpad, the agent forgets its goal. The 70-80% threshold prevents the context overflow error while leaving room for the next tool call.
