Here is the exact error I got:\n\n```\nFable 5's safeguards flagged this message. The safeguards are intentionally broad right now and may flag safe and routine coding, cybersecurity, or biology work.

I'm just trying to understand font rendering from the firmware up to avoid that stale look most e-readers have.\n\nI suspect the LLM is treating firmware modification as \"compromising a system.\" If writing a simple driver or custom rendering software for proprietary hardware is flagged as a security risk, it makes me wonder about the future of AI workflow for low-level dev. Does this mean any project involving reverse engineering or closed-source chips (like Broadcom) is going to trigger these broad filters?\n\nI'm trying to figure out if this is a prompt engineering issue or if the models are becoming too restrictive for real-world hardware projects. If the \"Cyber Verification Program\" is now a requirement just to tinker with an old e-reader, that's a steep barrier for a hobbyist.\n\n[Next Patreon Layoffs: AI Workflow Efficiency vs. Headcount →](/en/threads/2320/)", "url": "https://wpnews.pro/news/claude-code-getting-cybersecurity-refusals-for-hardware-hacks", "canonical_source": "https://promptcube3.com/en/threads/2339/", "published_at": "2026-07-23 13:48:36+00:00", "updated_at": "2026-07-23 22:06:09.837906+00:00", "lang": "en", "topics": ["ai-safety", "ai-policy", "ai-tools"], "entities": ["Anthropic", "Claude Code", "Fable 5", "Opus 4.8", "Cyber Verification Program"], "alternates": {"html": "https://wpnews.pro/news/claude-code-getting-cybersecurity-refusals-for-hardware-hacks", "markdown": "https://wpnews.pro/news/claude-code-getting-cybersecurity-refusals-for-hardware-hacks.md", "text": "https://wpnews.pro/news/claude-code-getting-cybersecurity-refusals-for-hardware-hacks.txt", "jsonld": "https://wpnews.pro/news/claude-code-getting-cybersecurity-refusals-for-hardware-hacks.jsonld"}}
