VS Code Extension

The Decodie VS Code extension lets you analyse code selections, get explanations, and ask follow-up questions — all within your editor.

Prerequisites

• Install the extension
• Configure an API key

Features

Analyse Selection

Select code in your editor, right-click, and choose Decodie: Analyse Selection. Decodie will generate structured learning entries for the selected code, including:

• A title summarising the pattern or concept
• A focused code snippet
• An explanation of why the code works this way
• Alternatives that were considered
• Key concepts to take away

The generated entries are saved to your .decodie/ directory.

Explain Selection

Select code and choose Decodie: Explain Selection for a quick, inline explanation without creating a persistent entry. Useful for understanding unfamiliar code on the fly.

Q&A

Open the Decodie sidebar panel to ask follow-up questions about any learning entry. The conversation is contextual — the LLM sees the entry’s code, explanation, and your conversation history.

Conversations are saved locally in .decodie/conversations/ so you can pick up where you left off.

Settings

Setting	Default	Description
decodie.model	(empty)	LLM model override. Leave empty for the provider default.
decodie.apiKey	(empty)	Deprecated. Use .decodie/.env instead. If set, treated as an Anthropic key.

Tips

• The extension reads your .decodie/.env file for the API key, so you can use different providers per project.
• If no API key is found in the project, the extension checks environment variables and VS Code settings as fallbacks.
• The Analyse and Explain features use generateText (non-streaming) for structured output. Q&A uses streamText for real-time responses.
