Your host says it patched PHP. What would confirm that?
Ask for evidence tied to the PHP runtime serving each site, then check the application journeys that matter after the update.

The demo works. What happens on the second try?
A booking page can look finished after one successful click. Try the retry, the last available place and the uncertain response before customers rely on it.

No agent? No problem.
Less juggling.
More handled.
A party to plan. A gift drive to organize. Sometimes the useful thing is a simple checker and a good set of pages.

Different jobs.
Same practical streak.
Independent. Practical. JustHandled.
Built with a
working purpose.
JustHandled Labs is built by H.J. Westerfield, bringing communications, editing and practical AI systems together around one question: what actually helps get the job done?
Meet the person behind the work ↗A few useful answers.
What is an agent skill?
A focused set of instructions, sometimes with supporting scripts and references, that helps an AI agent handle a particular task. Check the skill’s requirements and example output before choosing it.
How do I access a skill?
Access depends on the destination. Agensi offers agent-connected access. Gumroad offers downloadable packages where listed, and GitHub hosts a free installable subset. Each product page explains its available routes.
Will it work with my AI assistant?
SKILL.md support alone does not guarantee that a host can run every skill. Check the listed tools, runtime requirements and access method. We have tested Model Release Impact Mapper’s retirement workflow through Agensi in Claude with Python execution. Other skills and hosts still need their own checks.
