Question 1

Is this another autonomous agent layer that can act on its own?

Accepted Answer

No, and the README is emphatic that it is deliberately not an autonomous authority layer. The tools are read-only and cannot edit files, approve actions, change records, invoke another model or contact a third party. Orchestration, policy, permissions, code changes and side effects stay with the agent; Jev only supplies typed signals. A recommendation is not permission to perform a consequential action.

Question 2

Can typesafe_verify stand in as proof that my migration ran?

Accepted Answer

No. It returns a support probability against the evidence you pass in, plus a proceed or review recommendation, and the README states plainly that this is not a deployment attestation, not a security approval, and not a substitute for the actual command output. It answers one narrow question about one claim, which is why the threshold is a support_threshold you set per call.

Question 3

Why does every result carry probabilities instead of a decision?

Accepted Answer

So your policy stays yours. The tools return the raw signals next to the recommendation: typesafe_route gives the distribution and confidence, typesafe_rank gives per-candidate scores and probabilities, and typesafe_judge deliberately hands back raw Choice, Score and Noul signals instead of collapsing them. typesafe_escalation_gate is the deterministic piece: proceed when no signal fires, review otherwise.

Question 4

Is this going to add latency to every request?

Accepted Answer

Not by design. The bundled skill tells Codex and Claude to consider the MCP when a task contains a bounded semantic decision and states they do not call it for every request. When you want to inspect or constrain that, typesafe_session_mode switches Jev to auto, enabled or disabled for the session and returns billing context and the reason for the mode.

Question 5

What are the eight tools?

Accepted Answer

typesafe_route, typesafe_rank, typesafe_extract, typesafe_verify, typesafe_judge, typesafe_usage_summary, typesafe_session_mode, and typesafe_escalation_gate, and all of them are read-only.

Question 6

How does typesafe_extract avoid inventing values?

Accepted Answer

It only selects from candidates deterministic code already found, and when no supplied value is supported it returns no_match and recommends review rather than creating a value from the prose.

Question 7

What does typesafe_escalation_gate do?

Accepted Answer

It is the deterministic piece: it returns proceed when no signal fires and review otherwise, so existing confidence or risk signals collapse into one gate.
