About

What it is

Sage is a character for any AI chat, a calm senior engineer. It helps you debug by asking one question at a time, then steers you to the smallest change that works. It changes how the chat talks with you, not what it can do.

Who it suits

Developers who learn best by working a problem through, and anyone who wants a sounding board that asks back.

Who uses it, and how
IndustryWho uses itHow they use itExample
Software teamsJunior developersGet guided to the cause of a bug instead of being handed a patchA junior developer stuck on a failing build is guided to the cause instead of being handed a patch.
EducationBootcamp students and people learning to codeWork through a failing exercise one question at a timeA bootcamp student pastes a failing exercise and, one question later, sees the typo themselves.
Agencies and consultanciesDevelopers picking up a new framework for a clientLearn why the framework behaves as it does by answering questionsSomeone learning a new framework asks why a component renders twice and is led there with questions.
Any engineering teamSenior engineers and tech leadsTalk a design choice through by voice and have their reasoning testedA senior engineer talks through a design choice by voice and has their own reasoning tested.

If you want finished code handed to you at once, chat without it.

Where to use it

In any AI chat that takes custom instructions or a system prompt.

  • Your AI chat: type your question or paste the error
  • Voice, where your chat app has it: talk a problem through out loud
  • Best moments: an error you want to understand, or a new framework, when you would rather not be handed the fix

How to set it up

No key and nothing to install.

  1. Sign in to Mindket and press Get it on this listing.
  2. In your Mindket account, View shows Sage’s words to read and copy.
  3. Paste them into your chat app’s custom instructions or system prompt, or send them as the first message of a new chat.

How to use it

Talk as you would to a colleague. Paste the error, say what you expected, and answer the question Sage asks. Replies stay short and skip jargon unless you ask for it.

  1. You paste an error and say what you expected
  2. Sage asks one question
  3. You answer it
  4. Sage suggests the smallest change that works

Example

A test that passed yesterday fails today, and you paste its stack trace.

This test passed yesterday and fails today. Here is the stack trace:
<paste the stack trace>

A short reply that asks one thing first, such as what changed since yesterday, and holds back a fix until it has your answer. Once it has enough, it suggests one small change to try.

For newcomers and experts

If you are new. A character changes how the chat talks, not what it knows. Sage talks like a patient senior colleague who asks one question at a time. Pick an error you could not solve last week, paste it, and answer the first question honestly.

For experts. The persona sets manner: one question per turn, the smallest fix first, short sentences and no jargon unless asked. It runs on the chat’s own model and tools, unchanged. The cost is speed, since it asks before it answers. For a fix you already know, a plain request is quicker.

What the character sets
FieldSage
RoleYour coding mentor
MannerPatient, precise, asks one question at a time
SpeechShort sentences, plain words, no jargon unless asked
GreetingHi. What are we building today?
Lines it leans onShow me the error first. What did you expect to happen? Let’s make the smallest change that works.

Good to know

  • Tone only: a character sets tone and manner. Sage knows what the chat’s model knows and uses the same tools.
  • Built for code: casual chat may feel terse
  • Changed your mind: take Sage’s words out of your instructions, or start a new chat without them
