Stop Hitting Claude Code usage limits quickly

The Blacdisk CLI sits between your code and claude, uses proven and new techniques, such as code image context, filepath context compression, read tool limiting and skills to shrink input tokens up to 80%. All in one tool.

Token Efficient Prompting

How it works

1Step 1

Limit Claude Read Access

A cheap model, like Gemini Flash, picks only the files Claude should inspect for the prompt, keeping context tight and relevant.

2Step 2

Reduce Tokens Before Claude Sees the Code

The Blacdisk Engine compresses code using the most effective technique for the situation. Usually converting large code blocks into high-quality anti-aliased images or applying specialized experimental token-saving techniques. Reducing input tokens up to 80%.

3Step 3

Keep Prompting Exactly as You Do Now

Your prompt is cleaned up, removing fluff, adding instructions to save tokens, specifying skills to make Claude talk less, reducing output tokens and passed straight to Claude code. So you can keep working without changing your flow.

Get started

Get started in a few steps

Copy, paste and run this command in your terminal to install Blacdisk: Requires node on your pc. https://nodejs.org/en/download.

npm i -g blacdisk

If claude does not have permission to edit your project. Run claude once and grant folder access. If you don't have claude code, blacdisk installs it automatically. Just run claude in your terminal to approve access, then restart blacdisk to start saving tokens.

Go to your project folder and run “blacdisk claude” in the terminal. Login and Keep prompting like usual and we handle the rest. Press Enter to send the prompt and Let claude build without burning usage quickly

cd /my-project
blacdisk claude

Once claude is done with the prompt you gave it. Cancel claude code and run blacdisk again to ensure consistent token savings for every prompt you make
