AI Software Agent

Handyst

Techyst developed Handyst around the way engineering teams already deliver work: describe the change, let the agent operate in an isolated environment, and review a concrete pull request. Open Handyst ↗

Overview

The
gist

Handyst works directly from a code repository and a plain-language task. It explores the existing implementation, edits the required files, runs project commands and tests in an isolated runtime, and prepares changes in a reviewable delivery format.

Problem → fix

Why we
built it

We kept hitting the same annoying problem, so we built the thing we wanted to use.

/001/Challenge

The product problem

Coding assistants often stop at suggestions or isolated snippets, leaving developers to understand the repository, apply changes across files, run verification, and package the work for review.

/002/Solution

What the experience needed

Handyst gives the agent a contained execution environment and an end-to-end software task flow, connecting repository context, file changes, command execution, test feedback, and pull-request delivery.
