Small tools for a careful web.
Sentinel Tools is a suite of focused, single-purpose security utilities built by Jeremy Hayes. Each one does a narrow job well and reports honestly about what it can and cannot see.
What these tools are
Quick first-pass checks. LinkSentinel inspects URLs before you click. RepoSentinel reads the public surface of a GitHub repository before you clone. FileSentinel verifies files on your own machine before you open them. All three produce plain-English reports with an explainable score.
What these tools are not
Not an antivirus, not a penetration test, not a guarantee. A passing report means no obvious issues were detected by these checks — nothing more. Treat the reports as one input to your own judgment, not a substitute for it.
