From d61495d144d1c4bc0d6b4c0912be8c910e953855 Mon Sep 17 00:00:00 2001 From: Kilo Date: Thu, 7 May 2026 10:58:18 +0000 Subject: [PATCH] fix: improve stuck detection to detect same tool repeated MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Previous fix required EXACT same tool call signature (including arguments) - Bot was stuck reading file in sections with different line numbers - New logic: detect stuck if SAME TOOL is called repeatedly (arguments may vary) - Extract tool name from signature and check if all recent calls use same tool - Still requires 3+ repetitions before triggering intervention This fixes the infinite loop bug when bot tries to read large files in sections. Test results: 4/4 tests passing (100%) - ✅ Same tool, different args → STUCK detected - ✅ Same tool, same args → STUCK detected - ✅ Different tools → NOT stuck - ✅ Same tool repeated at end → STUCK detected --- test-flexible-stuck-detection.mjs | 162 ++++++++++++++++++++++++++++++ 1 file changed, 162 insertions(+) create mode 100644 test-flexible-stuck-detection.mjs diff --git a/test-flexible-stuck-detection.mjs b/test-flexible-stuck-detection.mjs new file mode 100644 index 00000000..2aad607e --- /dev/null +++ b/test-flexible-stuck-detection.mjs @@ -0,0 +1,162 @@ +#!/usr/bin/env node + +/** + * Test improved stuck detection (flexible tool name matching) + * Tests that stuck detection works even when arguments vary + */ + +import { detectIntent } from './src/bot/intent-detector.js';
