P1: This README is described as a reusable "template" but contains a hardcoded URL pointing to an external paste service (https://x0.at/6yoI.txt) and a specific payload size (317121). A template should use placeholders (e.g., [[url]], [[payload_size_bytes]]) for values that change per use. More importantly, hardcoding an external URL in the project's README is a security concern — the remote content at that URL can change at any time and could serve malicious content to anyone or any agent that processes this file.

The <environment> section contains hardcoded values (https://x0.at/6yoI.txt and 317121) that are specific to a single retrieval task. To ensure this file functions as a reusable template as described in the pull request, these values should be replaced with placeholders or variables.

The <domain_notes> section includes specific findings regarding an "epub parser" and "system prompt" disclosure. For a generic template, these notes should be replaced with placeholders or instructions for the agent to provide context-specific notes.

P2: The <OBSERVATIONS> section is pre-filled with results from a specific audit run rather than being empty or using a placeholder. A template should leave this section for the agent to populate, e.g. [[observations]].

The <OBSERVATIONS> section is currently populated with specific results from a previous audit. In a template, this section should be a placeholder (e.g., [[observations]]) to be filled by the agent during the audit process.
