Yukti

Yukti lets you ask Codex about everything visible above the current notebook cell. The notebook stays the conversation: markdown, code, outputs, earlier questions, and earlier answers all become context for the next %%ask question.

Install for development

You need JupyterLab 4, Node.js, and an authenticated Codex CLI.

codex login
cd /Users/yeshwanth/Code/Personal/yukti
npm install
npm run build:prod
uv pip install -e .

Restart JupyterLab after installation.

Use Yukti

Load the kernel extension once near the top of the notebook:

%load_ext yukti

Then ask a question in a cell:

%%ask
Why did the previous query return these rows?

Yukti sends cells above that question through a Jupyter Comm channel. Outputs are limited to 8 KB each, and the complete request is limited to 512 KB. Yukti starts a disposable Codex App Server thread with its own visible base instruction, an empty working directory, a read-only sandbox, and no project instruction files.

Yukti accepts only ChatGPT subscription authentication. It stops before the model call when Codex reports API-key authentication.

See the exact Codex request

Add --debug to show the authentication type, base instruction, thread settings, and complete notebook transcript in the cell output:

%%ask --debug
Why did the previous query return these rows?

Debug mode starts the local App Server protocol and stops before the model turn.

Verify the installation

jupyter labextension list
python -m compileall -q yukti

The extension list should show yukti as enabled.
