How Peesuto recognises it

An error line (TypeError: …, Exception in thread …, panic: …, PHP Fatal error: Uncaught …, Ruby's file.rb:12:in 'm': … (ErrorClass)) followed by its stack trace, or a Python traceback with the error last. Frames from libraries (node_modules, site-packages, gems, vendor…) are dimmed and your own are marked.

The exact rules are in docs/templates.md.
