Pi Claude Pro — Development skill for Claude Code

[](https://github.com/HugoLopes45/pi-claude-pro/actions/workflows/ci.yml) [](https://www.npmjs.com/package/pi-claude-pro) [](https://pi.dev/packages/pi-claude-pro) [](LICENSE)

Use your Claude Pro or Max subscription in [Pi](https://pi.dev), with your usage in the footer and a clear message when a limit is spent.

What it does

When the Anthropic model uses a subscription token, the extension:

• sends the request with the Claude Code identity: user agent, x-app header, session header and billing block;
• moves Pi's documentation section from the system prompt to the start of the first user message;
• uses the full context window from Pi's model catalog;
• shows your 5-hour and weekly usage in the footer;
• replaces the error of a spent limit with a clear message and its reset time, and stops pointless retries.

Requests that use an Anthropic API key are not changed.

Compatibility with other extensions

The adapter accepts structured Pi prompts and complete text prompts returned by other extensions. It does not require a specific extension configuration.

Only complete `` blocks starting with `Pi documentation` are moved. Custom documentation, instructions, tools and skills remain unchanged. Unrecognized or fragmented documentation stays in place.

Requirements

• Pi. CI checks the lockfile baseline and the latest published Pi packages; see the compatibility policy below.
• A Claude Pro or Max subscription.

[Claude Code](https://docs.anthropic.com/en/docs/claude-code) is optional. When `claude` is on the `PATH`, the extension sends its version. Otherwise it sends the bundled version, 2.1.289.

Install

pi install npm:pi-claude-pro
