- Repository: https://github.com/pankajudhas81/pi-claude-auth
- License: MIT
- Adapted files in this repository:
  - `src/billing.ts`
  - `src/subscription-credentials.ts`

The original project is MIT licensed. Its license permits use, modification,

## gotgenes/pi-anthropic-auth

- Repository: https://github.com/gotgenes/pi-anthropic-auth
- License: MIT
- Adapted files in this repository:
  - `src/anthropic-shape.ts`

`src/anthropic-shape.ts` reimplements that project's system-prompt sanitizer and
its summarization-transcript reasoning strip. It is written against this package's
own shaping entry point rather than copied verbatim (the upstream version parses
pi's prompt into typed chunks; this one scans the rendered string), so the
algorithm, the anchor strings and the measured reasoning behind them are what came
across.
