README

pi-devtools

Developer inspection tools for pi: peek under the hood at what pi sends to the model and how the API responds.

Install

pi install npm:pi-devtools

Then /reload or restart pi.

Tools

/system-prompt

Print the current session's full system prompt — exactly what pi sends to the LLM. Styled for scanning: section headers are bold+highlighted, bullet markers are dimmed, XML wrappers are muted.

Press Esc or q to close.

Model API Inspector

Every provider round-trip is rendered as an inline panel in the chat:

  • Collapsed: one dense line — API provider/model status latency ↑tokens ↓tokens ⚡cache% $cost time
  • Expanded (Ctrl+O on the panel): HTTP method + URL, status, latency, request ID, stop reason, notable headers (rate limits, retry hints), then raw request/response JSON

The inspector resets each turn so you only see calls for the current prompt. Steering/follow-up messages during streaming also reset the panel.

Configuration

Edit CONFIG at the top of model-api-inspector.ts:

Option Default Description
maxCalls 5 Most recent calls to show (Infinity = all)
maxStringLen 50 Truncate strings in raw JSON
showRaw true Show request/response JSON in expanded view
hidePaths ["tools"] JSON paths to collapse to a placeholder
headerFilter /ratelimit|rate-limit|retry-after|request-id/i Response headers to surface
