The developer states the tool is not a hardened sandbox and can be bypassed by a capable person or process, and is seeking community feedback on its usefulness and whether companies would adopt it.", "body_md": "Hi all, With everybody (and especially companies) using AI agents, I have decided to work on a deterministic guardrail tool for AI agents.\n\nWhat does it mean? On the same way that an AI agent can run “terraform plan”, it can also run “terraform destroy”. The tool ALLOWS or BLOCKS AI commands accordingly, to avoid unexpected “tragedies”. Please, note that this is not a hardened sandbox. The tool can be bypassed by a capable person or process, since this is my first proof of concept.\n\nI would like to present it to the community and receive honest feedback (pros, cons, issues, concerns, is it really useful? Would companies be interested in using it?). Please, feel free to visit the GitHub page, read more details in the README file and download it to try.\n\nThanks!!\n\nComments URL: [https://news.ycombinator.com/item?id=50117268](https://news.ycombinator.com/item?id=50117268)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-deterministic-ai-agents-guardrail", "canonical_source": "https://github.com/aws-safebox/aws-safebox", "published_at": "2026-10-16 11:53:12+00:00", "updated_at": "2026-10-16 12:14:30.024336+00:00", "lang": "en", "topics": ["ai-agents", "ai-safety", "developer-tools", "ai-tools"], "entities": ["GitHub", "Hacker News", "Terraform"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-deterministic-ai-agents-guardrail", "markdown": "https://wpnews.pro/news/show-hn-deterministic-ai-agents-guardrail.md", "text": "https://wpnews.pro/news/show-hn-deterministic-ai-agents-guardrail.txt", "jsonld": "https://wpnews.pro/news/show-hn-deterministic-ai-agents-guardrail.jsonld"}}
