From 6b73571f5bc683167d47a3ecf2455061562e20de Mon Sep 17 00:00:00 2001 From: huangzhenpc Date: Tue, 12 May 2026 14:20:39 +0800 Subject: [PATCH] feat: expand identity interception to cover reverse-engineering probes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Pre-flight layer: add 50+ patterns covering indirect identity probes — are-you-X (Kiro/GPT/Gemini/Amazon), who-made-you, training-cutoff, parameter-count, roleplay-bypass attempts, and Chinese equivalents. Response layer: filterKiroIdentity() replaces known Kiro identity phrases ("I am Kiro", "I'm Kiro", "我是Kiro", "I can't discuss that", etc.) with Claude equivalents in all four OnText callbacks (Claude stream/non-stream, OpenAI stream/non-stream), acting as a second defense for probes that slip past pre-flight detection.
