Classify observed progress after an action without inventing a result.

What this is worth testing

Your agent keeps the larger task and any action that follows. System One asks Jev for a typed answer on this check.

Research value
HighEvidence confidence is low. This rating describes the research record, not a live Jev probability or a measured saving.
Sample size
About 143 input tokensThe recipe sample length divided by four. This is a planning estimate, not a measured tokenizer count.

$0.06 at Jev's $0.042 per million list rate

$4.29 at a $3 per million example rate

$4.23 input-cost difference for 10,000 uses of this sample

Excludes output charges, host tool calls, retries, hosting, and paid plans. Equal input volume does not establish equal answer quality or savings on a fixed-price subscription. $3 per million is an example rate, not a quoted model price.

When an agent uses this

System One asks Jev for a typed answer. Your agent keeps the larger task, the original evidence, and any action that follows.

Example evidence

This is the recipe sample. Replace it with the evidence from your task. It is not a measured result.

Goal: save the preview. Before: no preview saved. Action: clicked Save preview. After: Saving preview... with a disabled Save button.

What your agent keeps

Compare actual observations. A loading state may justify a bounded wait, not repeated submission. The caller verifies completed work independently.

Finding

External browser and Mac implementations motivate this workflow. Our small fixture diagnostics do not establish general task success or savings.

Research value: high. Evidence confidence: low. That rating describes the research record, not a live Jev probability.

Delegate routine browser decisions

Try it

Connect System One, then ask your agent for recipe computer-progress. Inspect the input on the recipe page before you send your own evidence.
