ReAct fallback extension for the Pi Coding Agent.

Text-based tool calling bridge for models without native function calling support.

pi install "npm:@vtstech/pi-react-fallback"

Automatically loaded — no commands needed. When a model lacks native tool calling:

Parses Thought:, Action:, Action Input: patterns from model output
Multi-dialect support: classic ReAct (Action:), Function (Function:), Tool (Tool:), Call (Call:) — each with dynamically-built regex patterns
Multiple regex strategies including parenthetical style and loose matching
Bridges text-based tool calls into Pi's native tool execution pipeline
Falls back when native tool calls fail
Disabled by default; toggle via /react-mode with persistent config across restarts
