Use the result as advice. Review missing or low-probability answers; the calling agent retains authority.

Potential value: medium. This is a research judgment, not a measured return.

Agent flow / decideReview a proposed tool callClassify a proposed tool call as clear or caution before anything runs.Not ratedEvidence confidence

THE JOB

Review a proposed tool call

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.

Evidence, findings and limits ↗

EXAMPLE INPUT

Agent flow / decideChoose who should handle a requestSend a request to deterministic code, a specialist model, or a person.Not ratedEvidence confidence

THE JOB

Choose who should handle a request

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.

Evidence, findings and limits ↗

EXAMPLE INPUT

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

Verification / decideReview a draft before it is sentCheck a draft reply against the evidence, then recommend send, hold, or review.Not ratedEvidence confidence

THE JOB

Review a draft before it is sent

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.

Evidence, findings and limits ↗

EXAMPLE INPUT

Verification / decideReview a proposed refundCheck whether a refund request names an amount and looks like a duplicate charge.Not ratedEvidence confidence

THE JOB

Review a proposed refund

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

Coding / decideCompare issue reportsFlag whether two reports describe the same observed failure.Not ratedEvidence confidence

THE JOB

Compare issue reports

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

Advice only. The browser companion owns observed targets and freshness checks. The calling agent owns authorization and verifies the outcome.

Computer use / decideMatch a visible controlChoose a control ID from descriptions captured by your browser tool.lowEvidence confidence

THE JOB

Match a visible control

Supply observed IDs and descriptions as candidates. A returned ID never supplies permission. Re-observe after a page change; never execute a model-generated selector or coordinate.

Potential value: high. This is a research judgment, not a measured return.

THE JOB

Check a form against the task

Prefer exact comparisons for explicit values. This semantic check never grants permission to submit. Preserve original values and review conflicting answers.

Potential value: high. This is a research judgment, not a measured return.

THE JOB

Read what changed on screen

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