OAICLI

A .NET CLI that uses the OpenAI Chat Completions API (gpt-4o) to generate unit tests and XML documentation comments for C# code in the current solution.

What it does

OAICLI scans the current .sln and .csproj files, gathers C# source files, and posts them to OpenAI along with a structured prompt and response schema. The model returns JSON containing a summary, file edits, and a commit message; the tool then displays the diff and (optionally) applies the changes.

Command	Status	Purpose
test (default)	available	Generate MSTest unit tests for the current solution.
document	available	Add or improve XML doc comments on C# files.
code-review	stubbed	Source exists; the file-diff and atomic-write logic is currently commented out.

Tech

• Built on ktsu.Sdk.App (multi-targeted from netstandard2.0 through net10.0).
• CLI uses Spectre.Console.Cli with CommandLineParser for option parsing, plus Spectre's Json and ImageSharp extensions for rich console output.
• Calls the OpenAI HTTP API directly (POST https://api.openai.com/v1/chat/completions) — does not depend on any OpenAI SDK.
• The expected response schema is generated via NJsonSchema.
• Hard-codes the gpt-4o model.

Auth

On first run the tool prompts for an OpenAI API key and stores it locally via ktsu.AppDataStorage (typically %APPDATA%\ktsu\OAICLI on Windows). Subsequent runs reuse the stored key.

Installation

git clone <repo>
cd OAICLI
dotnet build
