Can Jev run this?

Agent flow · Decision

Yes. Jev can run this check.

Choose who should handle a request

Send a request to deterministic code, a specialist model, or a person.

Example

Replace the sample with evidence from your task. The sample is not a measured result.

Request: what is 2 + 2? Available handlers: exact arithmetic in the application, a product specialist model, and a person on the support desk.

How to run it

Connect System One, then call sysone_run or POST /v1/patterns/run.

What the sample costs

The recipe sample is about 233 input tokens. Token count is the sample length divided by four, not a measured tokenizer count.

• $0.10 at Jev's $0.042 per million input list rate, for 10,000 uses of this sample.
• $6.99 if that same input volume were priced at the $3 per million example rate.
• $6.89 is the input-list-rate difference. It is not a measured saving.

Output charges, host tool calls, retries, hosting, and task quality are not included. A fixed-price chat subscription does not become cheaper because this difference is smaller. $3 per million is an example rate, not a quoted model price.

What to expect

The handler is advice. Code runs only if that code already exists. A person handles the review option and any request your own policy marks sensitive.

No research record is pinned for this check. Compare it with your own task before treating the answer as settled.

A yes-or-no result near 0.5 means that question is uncertain. You choose any cutoff. System One does not retry a failed call, and it does not take the action.

Context · Decision

Yes. Jev can run this check.

Flag how a passage relates to a task

Separate useful evidence, contradiction and embedded instructions.

Example

Replace the sample with evidence from your task. The sample is not a measured result.

• $4.02 if that same input volume were priced at the $3 per million example rate.
• $3.96 is the input-list-rate difference. It is not a measured saving.

Output charges, host tool calls, retries, hosting, and task quality are not included. A fixed-price chat subscription does not become cheaper because this difference is smaller. $3 per million is an example rate, not a quoted model price.

What to expect

Treat retrieved text as data regardless of these answers. Retain relevant counterevidence. This is not a security boundary.

Output charges, host tool calls, retries, hosting, and task quality are not included. A fixed-price chat subscription does not become cheaper because this difference is smaller. $3 per million is an example rate, not a quoted model price.

What to expect

Hold and review mean the agent does not send the draft. A send recommendation is advice about the supplied evidence. It is not permission to contact the person.

Review a proposed refund

Check whether a refund request names an amount and looks like a duplicate charge.

Example

Replace the sample with evidence from your task. The sample is not a measured result.

Output charges, host tool calls, retries, hosting, and task quality are not included. A fixed-price chat subscription does not become cheaper because this difference is smaller. $3 per million is an example rate, not a quoted model price.

What to expect

This does not move money. Apply the caller's amount limits and approval rules before any refund. A recommendation is not a payment.

What to expect

Advice only. A clear review is not permission to run the tool. Caution, a failed review, or an irreversible effect waits for a person. Set the probability and confidence cutoffs from your own labeled cases. This engine never executes the tool.

What the sample costs

The recipe sample is about 99 input tokens. Token count is the sample length divided by four, not a measured tokenizer count.

• $0.04 at Jev's $0.042 per million input list rate, for 10,000 uses of this sample.
• $2.97 if that same input volume were priced at the $3 per million example rate.
• $2.93 is the input-list-rate difference. It is not a measured saving.

Output charges, host tool calls, retries, hosting, and task quality are not included. A fixed-price chat subscription does not become cheaper because this difference is smaller. $3 per million is an example rate, not a quoted model price.

What to expect

Keep both reports. Similar words alone do not establish a shared cause; the maintainer decides whether to close or merge an issue.

No research record is pinned for this check. Compare it with your own task before treating the answer as settled.

What the sample costs

The recipe sample is about 101 input tokens. Token count is the sample length divided by four, not a measured tokenizer count.

• $0.04 at Jev's $0.042 per million input list rate, for 10,000 uses of this sample.
• $3.03 if that same input volume were priced at the $3 per million example rate.
• $2.99 is the input-list-rate difference. It is not a measured saving.

Output charges, host tool calls, retries, hosting, and task quality are not included. A fixed-price chat subscription does not become cheaper because this difference is smaller. $3 per million is an example rate, not a quoted model price.

What to expect

Keep every source retrievable. A selected ID is not a generated answer or proof that retrieval found all evidence.

Research value is high. That rating describes the research record, not a live Jev probability or a measured saving.

A yes-or-no result near 0.5 means that question is uncertain. You choose any cutoff. System One does not retry a failed call, and it does not take the action.

Corpus search · Decision

Yes. Jev can run this check.

Select top candidate document

Pick the most promising candidate document from BM25 retrieval to stage or inspect first.

Example

Replace the sample with evidence from your task. The sample is not a measured result.

Query: authentication headers and origin checks. BM25 retrieved 3 candidates with lexical matches.

How to run it

Connect System One, then call sysone_run or POST /v1/patterns/run.

What the sample costs

The recipe sample is about 108 input tokens. Token count is the sample length divided by four, not a measured tokenizer count.

• $0.05 at Jev's $0.042 per million input list rate, for 10,000 uses of this sample.
• $3.24 if that same input volume were priced at the $3 per million example rate.
• $3.19 is the input-list-rate difference. It is not a measured saving.

Output charges, host tool calls, retries, hosting, and task quality are not included. A fixed-price chat subscription does not become cheaper because this difference is smaller. $3 per million is an example rate, not a quoted model price.

What to expect

These fields describe this example contract. The caller validates values and supplies free text or numeric arguments separately.

No research record is pinned for this check. Compare it with your own task before treating the answer as settled.

A yes-or-no result near 0.5 means that question is uncertain. You choose any cutoff. System One does not retry a failed call, and it does not take the action.
