How We Are Using Jev – Sapience Cloud

Overview

Jev is a fast decision model from TypeSafe. It doesn't write answers. It makes quick judgments, like "which of these options fits this message best?", and says how sure it is about each option. Sapience uses Jev just before your chat message goes out, to help in four ways:

Skill suggestions. It offers the skills that fit what you're trying to do, so you don't need to know every skill by name.

Reply mode. It picks how hard the agent should think about this particular message: a quick answer, a balanced one, or a longer, more careful one.

Agent suggestions. When you're talking to the Sapience Agent, it can point out a specialist agent that suits your request better.

Plan mode suggestion. When your request is a big, multi-step job, it offers to have the agent draw up a plan for your approval before it starts.

All four are part of one preview, which is off by default. Jev never decides anything for you without showing it: a skill, an agent or plan mode is only used if you pick it, and a mode it chooses is always shown on screen and you can change it. If Jev is slow or unavailable, your message simply sends as it normally would.

Turning It On

Open Menu ▸ Settings ▸ Advanced.

Tick Preview: Jev skill, mode & agent suggestions.

Optionally, set Skill-suggestion history (turns). This is how many recent messages Jev reads for context, from 1 to 30. The default is 10.

Both settings are saved to your account, so they follow you to every device.

What Happens When You Press Send

You type your message and press Send.

Sapience asks Jev about your message. One question covers skills, reply mode and whether to suggest a plan. If you're talking to the Sapience Agent, a second question about agents runs at the same time, so it adds no extra wait.

Jev looks mainly at the message you're sending now. Earlier messages are only context, so an old request in the conversation won't trigger a suggestion for a new message that doesn't need one.

Every question includes a "none of these" answer, and it wins ties. A greeting, a quick question or a simple edit therefore gets no suggestion at all.

The reply mode is applied quietly and shown on the mode chip. If there are skills, agents or a plan worth offering, a popup opens. Otherwise your message sends straight away.

Skill Suggestions

When Jev finds skills that fit, a popup asks:

These skills seem relevant to what you're trying to do, would you like to use one of these skills?

It lists up to three skills, best match first. Hover over a name to read the skill's description.

You click	What happens
A skill	The skill is applied to this message, just as if you had chosen it from the skill list, and the message sends
Send without a skill	The message sends as normal
Back to editing (or Escape)	Nothing is sent, and your text stays in the message box

Jev doesn't suggest skills when you've already chosen one, either from the skill list or by typing /skill-name.

Reply Mode And The Mode Chip

Every message is also given the reply mode that suits it:

Mode	When Jev picks it	Example
Minimal - Fast	A short, factual question	"What is the capital of Australia?"
Balanced (default)	Most everyday requests	"Draft a short reply to Sam saying I can meet Thursday"
Detailed: think longer	A request that needs careful analysis	"Why is our churn rising? Think this through carefully"

Balanced stays in place unless another mode is a clear fit, so Jev doesn't switch modes over a close call.

A mode chip next to the message box always shows the mode in use. Hover over it to see "Mode chosen for this message — click to change", and click it to open the mode picker.

Your choice always wins. Once you pick a mode yourself, Jev doesn't change it for the rest of that conversation. That covers a pick from the mode picker, from the chip, or from a link that opens a chat in a set mode. A new conversation starts fresh.

Agent Suggestions (Sapience Agent Only)

The Sapience Agent is your general concierge, but you may have access to a specialist that's better suited, for example a contract reviewer or a stock-market analyst. When you message the Sapience Agent, Jev compares your request with every agent you can use, installed or not. It reads each agent's name, description and welcome message.

If a specialist is a clearly better fit, the popup shows a section titled:

A specialist agent may suit this better

You click	What happens
A suggested agent	That agent takes over this same conversation and replies to your message, just like @-mentioning it. Nothing is lost and no new chat is opened
Keep the Sapience Agent	The Sapience Agent answers as usual

Casual messages ("hi, how are you?") never trigger an agent suggestion. When you're already talking to a specialist agent, this check doesn't run at all.

Plan Mode Suggestion

Plan mode makes the agent lay out a plan and wait for your approval before it does anything. That is the right way to start a big job, but it's easy to forget to ask for it. When your message is clearly a substantial, multi-step piece of work, such as a migration, a build, a multi-part research project or a deliverable with several stages, the popup adds a section titled:

Plan this first?

For example, "Migrate our CRM from HubSpot to Salesforce, including data mapping, testing and the cut-over" gets the offer. A quick question, a typo fix, a short email draft or a request to explain something does not.

You click	What happens
Plan this first	Plan mode is switched on for this message only. The agent proposes a plan for your approval before it acts, and your next message goes back to normal
Send without a plan	The message sends as normal
Back to editing (or Escape)	Nothing is sent, and your text stays in the message box

This section only appears when Jev is quite sure the job needs planning, and never when plan mode is already on. If you'd rather always plan, you can still switch plan mode on yourself from the plan chip or with Shift+Tab, as before.

Quick Reference

Feature	When it runs	What you see	Who decides
Skill suggestions	Every message, unless you already chose a skill	Popup with up to 3 skills	You
Reply mode	Every message	Mode chip beside the message box	Jev, unless you picked a mode
Agent suggestions	Messages to the Sapience Agent	"A specialist agent may suit this better" section	You
Plan mode suggestion	Big, multi-step requests, when plan mode is off	"Plan this first?" section	You

Summary

With the preview on, Jev makes four quick judgments before each message: which skills fit, which reply mode suits it, whether the job is big enough to plan first, and, with the Sapience Agent, whether a specialist would serve you better. Suggestions are always yours to accept or ignore. The chosen mode is always visible and changeable, and if Jev can't answer in time, your message goes out exactly as it would have.
