Autofix Extension for Malformed JSON
Automatically fixes broken JSON in tool calls using Synthetic's
hf:syntheticlab/fix-jsonmodel.Why?
Some models generate malformed JSON (missing quotes, trailing commas, etc). This extension catches those errors and fixes them automatically, so tool calls don't fail.
Quick Start
Then use
/test-autofixto try it out.How It Works
Uses the new
onToolCallParsehook from https://github.com/clebreto/pi-mono/pull/feature/hook-based-tool-parsing:Config
PI_AUTOFIX_ENABLED- turn on/off (default: true)PI_AUTOFIX_MODEL- which model to use (default: hf:syntheticlab/fix-json)SYNTHETIC_API_KEY- your API keyFiles Changed
