TessaCodeTools

Tell me what is broken.

One person builds and reads everything here, so a message about a tool that fails on your input is the single most useful thing you can send.

What gets a fast reply

  • A tool that produces the wrong output. Include the exact input if you can share it. Most parser bugs are one specific character in one specific position, and a real example finds it in minutes rather than hours.

  • A tool that fails on a valid input. Especially for the YAML, cron, and CSS tools, where the specifications are large and this implementation covers the practical subset rather than every corner.

  • A tool you keep searching for. The build list is driven by what people actually need, and a single clear request is usually enough to put something on it.

  • Anything privacy-related. If you spot something that contradicts the privacy policy, that goes to the top of the list.

What I cannot help with

I cannot debug your application, recover a file you converted, or tell you what a token you decoded means. The tools keep no history, so once a tab is closed the data is gone from everywhere, including from me.


Please also do not email me live credentials for diagnosis. If a token fails to decode, describing its shape is enough: the algorithm in the header, the approximate length, and what error appeared.


Other ways to reach me

Email is best: nosborne@tessacodesolutions.com


There is no form that posts to a server here, and that is deliberate. The whole site is static with no backend, which is what lets the tools promise that nothing is uploaded. Adding a form endpoint just for this page would undercut the claim, so the composer above hands off to your own mail client instead.


Response time

This is a side project, so allow a few days. Bug reports with a reproducible input get looked at first, because they are the ones I can actually act on.
