@ryan_nookpi/pi-extension-cc-system-prompt

Use your Claude Code subscription (Max, Team, Enterprise) with pi.

Claude Code's API uses a dedicated system prompt to identify itself. This extension swaps pi's system prompt with that Claude Code-style prompt when you select a Claude model, so the API recognizes requests as coming from Claude Code and routes them through your subscription plan.

Pi's original system prompt is preserved by injecting it once as a persistent <system-reminder> message.

Install

pi install npm:@ryan_nookpi/pi-extension-cc-system-prompt

Great for

• experimenting with Claude Code-flavored prompt behavior inside pi
• keeping pi's original guidance available as a reminder
• using a vendored, reviewable prompt source instead of a remote dependency

Behavior

• Applies only when the selected model ID starts with claude-
• Replaces pi's system prompt with a curated Claude Code prompt assembled from vendored prompt fragments
• Injects pi's original system prompt once as a persistent reminder message

Notes

• No additional API charges — requests are billed against your existing Claude Code subscription.
• This relies on undocumented Anthropic internal behavior and may break at any time without notice.
• Vendored prompt fragments come from Piebald-AI/claude-code-system-prompts.
