J Jev ArchitectGitHub ↗
An agent skill for builders

What could you build with Jev?

Explore new product ideas. Find better ways to run what you already have. Jev Architect helps your coding agent work out where Jev could help and what to test first.

Independent, open-source project.

An architect sketches how information becomes a decision, then an action or human review.
From an idea to a decision you can test.

Know where to startLeave with a first experiment and a way to judge it.

Start with the idea

Does this message need a reply?

“Can we move our meeting to Friday?” needs a reply. “Friday’s meeting is cancelled” usually doesn't. Jev can help find messages that need a reply. Your software can put them in one place for you to review.

1. A message arrives“Can we move our meeting to Friday?”

Your software gives Jev the message and any context it needs.

2. Jev makes a choiceNeeds a reply

For the question “Does the sender ask for a response?”

3. Your code actsAdd it to your reply queue.

Your software flags the message. You decide what to say.

Illustrative example. Jev can misread a message. Test it on examples you have checked yourself before relying on its answers.

The opportunity

What would you check more often?

A useful check can still be too slow or expensive to run every time. Jev Architect helps you explore what you could build if that changed, and test whether Jev makes it practical.

Improve something you have

Already using AI to make the same kind of decision repeatedly? Compare Jev against what works today.

  • Set the quality you need before comparing costs
  • Measure time and cost on the same inputs
  • Include cases that need another model or a person

Explore something new

Start with who you want to help and what they struggle with. The skill asks questions, explores possible solutions, and helps you choose one to test.

You don't need a codebase. Start with a problem you care about.

A faster decision is only useful if its mistakes are acceptable. The skill helps you define what happens when Jev is wrong or unsure.

What you get

A reason to build.
Or a reason to skip it.

Jev Architect compares the opportunities, checks current documentation, and proposes a first experiment. You'll know what to measure and what result would make the idea worth pursuing.

If an exact rule already works, keep it. If you need writing or broad reasoning, use an appropriate language model. Use Jev only if your tests show that its answers, speed, and cost are good enough for the job.

2. Open your agent and try a prompt

For Claude Code, run claude in your terminal to start a new session. Then paste a prompt below into its chat, not your terminal.

Use Jev Architect. I want to help adults practise spoken English between lessons. What could I build?
Use Jev Architect. My coding agent keeps retrying fixes that don't work. Could Jev help it notice when it's stuck and ask me for help?
Use Jev Architect. I want a browser assistant that finds invoices across supplier websites with different layouts. Could Jev help it choose what to click?
