From d86fa71fc4470145d3b3c4da8160063b6b2b9e43 Mon Sep 17 00:00:00 2001 From: shashank Date: Thu, 24 Sep 2026 21:51:54 +0530 Subject: [PATCH 1/2] FEAT: Add PromptTemplateConverter and deprecate TaskFramingConverter TaskFramingConverter is named for its original use, but all it does is insert the prompt into a template at a {{ prompt }} placeholder. This adds PromptTemplateConverter with the same logic under a generic name and a required `template` argument. TaskFramingConverter is now a thin subclass that keeps its `task_template` argument and default, emits a DeprecationWarning, and will be removed in 1.4.0. Its docstring starts with "Deprecated alias", so the converter registry no longer lists it. It keeps the `task_template` identifier param, so existing TaskFramingConverter identifiers and eval hashes are unchanged. The flip technique and the SATA docs/tests now use PromptTemplateConverter with the same template, so the output is unchanged. The flip technique's eval hash changes because the converter class changed. The converters doc gains hidden HTML/Markdown template examples for indirect prompt injection (XPIA), citing WASP, along with the strip_characters each hiding spot needs.

The "Deprecated alias" docstring prefix made the registry skip TaskFramingConverter, so ConverterRegistry.create_instance("TaskFramingConverter", ...) and ConverterService.create_converter_async(type="TaskFramingConverter") failed before the deprecation warning could run. The docstring no longer uses that prefix, so the class is discovered and built by name as on main until its removal in 1.4.0. Registry and service regression tests build it by name and check the warning and output. The Markdown hidden-text recipes in the converters doc now put the prompt on one line and backslash-escape "\" and the delimiter with SearchReplaceConverter before PromptTemplateConverter inserts it, so blank lines and trailing backslashes no longer make the prompt visible. PromptTemplateConverter still inserts text literally. New tests render both recipes with markdown-it-py (CommonMark) and Mistune and check that only the carrier text is visible.
