LeetCode Pseudocode Coach

A Chrome Manifest V3 extension that opens in the side panel on LeetCode problem pages, reads the current problem statement and examples, and uses OpenAI to simulate your pseudocode on a visible test case without revealing the full solution.

Run Locally

npm install
npm run build

Then open Chrome Extensions, enable Developer mode, choose Load unpacked, and select the generated dist folder.

Development

npm test
npm run build

The extension stores only provider settings in chrome.storage.local. Problem text, pseudocode, hidden references, and traces stay in memory for the current side-panel session.

MVP Notes

• Provider support is OpenAI-first via a provider adapter boundary.
• LeetCode data is extracted from the active problem page DOM.
• Pseudocode is simulated by the model and rendered as a step timeline.
• Guardrail sanitization strips common solution/code fields before rendering model output.
