Check a citation in context

Compare a claim with the supplied source passage.

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 moderate. This rating describes the research record, not a live Jev probability or a measured saving.
Sample size
About 116 input tokensThe recipe sample length divided by four. This is a planning estimate, not a measured tokenizer count.

$0.05 at Jev's $0.042 per million list rate

$3.48 at a $3 per million example rate

$3.43 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.

Claim: all accounts get unlimited exports. Source: free accounts may export ten files per day.

What your agent keeps

Check quote existence in code first. Preserve the source ID and context. This is advice, not certification.

Finding

Our small diagnostic and a controlled SRE study support testing the pattern. Both expose errors; neither establishes general reliability.

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

Catch a claim the evidence does not support

Try it

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