Find where the agent lost the plot.
Drag through a tool-using coding run. Watch goal, context, and tool state travel together, then extract the exact checkpoint another agent can resume.

The bundled trace contains eight events across agent, context and tool lanes. Three are agent actions, two context events and three tool results. At sixty pixels per event the lane counts measure one hundred eighty, one hundred twenty and one hundred eighty. The tool command and output are identical at events three, five and seven. Patches occur between those results, so this is not three consecutive retries with no intervening state change. The detection groups equal command-output pairs across the entire trace, then chooses the most repeated group. It is a local deterministic fixture, not a live coding run. The final meaningful file change occurs at event six, before the last repeated tool result at event seven. The handoff retains the first six events and names src slash routes slash checkout dot js. It assigns resume after event six, while remaining two events show the failure and the next intent. At forty pixels per event preserved six measures two hundred forty, remaining two eighty and total eight three hundred twenty. This retains a checkpoint but does not test the actual file or fix checkout behavior. The suggested next action is to inspect request construction or add logging before repeating the same test. Assigned context tokens sum to two thousand four hundred twenty across all eight events. The first six sum to nineteen hundred eighty, leaving four hundred forty in the later two. At one pixel per ten tokens the bars measure two hundred forty two, one hundred ninety eight and forty four. The handoff display labels six of eight events preserved; its JSON includes selected payloads rather than token counts or measured savings. Pixi initialization safely returns if absent, then readable trace inspection, loop detection and export listeners still work. Verify the actual native JSON and reset independently, while absent animation cannot prove a healthy rendered timeline.
