How pages earn a place here
Indexable tools must have a working interaction, a reproducible method, concrete examples, important limitations, and a clear privacy statement. Pages that do not meet that bar are removed rather than left as public filler.
Verify important output
Formatting and encoding tools can still produce the wrong result for a specific style guide, locale, protocol, or security context. Check the cited standard and test with representative input before using output in production.
