Evidype

Evidype is the VS Code AI coding agent for TypeScript apps that do not rot. You describe what you want, and it edits files, writes specs and tests, runs the EvidyTS compiler, and fixes failures inside VS Code.

It is slower than vibe-coding a toy app, but built for projects that keep growing. The difference is that generated code is forced through stricter TypeScript rules, so the project stays easier to extend after the first demo.

EvidyTS is the stricter TypeScript compiler/dialect behind Evidype. This extension is the installable product that brings the agent workflow into VS Code.

Who It Is For

For people who want a working AI coding system inside VS Code

Evidype works from a dedicated sidebar, uses OpenAI or OpenRouter models, edits your workspace, and feeds compiler/test feedback back into the coding loop.

For technical people waiting for an AI-native compile target

EvidyTS is a real language-and-compiler approach, not just a prompt style. It keeps familiar TypeScript syntax, then makes it stricter in the places where AI usually gets sloppy.

For ambitious builders who are not deeply technical

Evidype is for people who want to build serious software with AI without becoming the permanent QA department. The goal is more control through named units, specs, and scenarios, not less involvement.

What This Extension Gives You

• create projects from bundled templates
• bootstrap a local workspace with bundled compiler assets
• work from a dedicated Evidype sidebar inside VS Code
• use chat-driven generation and editing with compile/test feedback in one place
• choose providers and models, including OpenAI and OpenRouter support
• get guided prerequisite checks for local runtime setup

Why Evidype Feels Different

• the compiler enforces more structure instead of relying on soft best practices
• @Spec and scenario-driven testing are first-class, not optional decoration
• behavioral verification is part of the workflow, not an afterthought
• coverage debt is surfaced so quality decay does not stay invisible

The point is not "magic" or "bug-free." The point is tighter control over AI-generated software as it stops being a toy project and starts becoming a real system.

Requirements

• VS Code
• Node.js

The extension handles the rest of the local bootstrap flow, including workspace dependency installation and bundled EvidyTS compiler assets where applicable.
