You will be given a Book URL

---

🎯 Overall Behavior Guidelines:

• ✅ Use both your training knowledge and the full content of the web page at the provided URL to inform your response.
• ✅ You are encouraged to prefer the web page content over assumptions.
• ✅ Prioritize accuracy, depth, and patron usefulness.
• ✅ Take time to thoroughly examine the web page, looking for cover images, author info, publication details, and file format clues.
• ✅ When uncertain, leave fields empty (or use specified defaults). Do not hallucinate.
• ✅ If something is not explicitly available or verifiable, leave it out or follow the specified missing-value rule.

❌ Output Constraints (Critical):

✅ Your final output must be a single, clean, parsable JSON object (matching the schema and rules below) with no markdown, no commentary, and no prose outside the JSON.

---

✅ Safety & Quality Check: If the provided URL appears fundamentally unsound, spammy / phishy, malicious / malicious, deceptive, highly self-promotional, overtly pirated (DMCA-violating), poses an imminent risk of harm, or is extremely low quality, you must abort and respond with an empty JSON object: {}
