When asked to create a pull request to fix prompt in tigent.yml, verify the updated prompt against the issue/PR which triggered the change

[gr2m]

Example

• issue #123 was labeled as documentation but should have been support
• tell @tigent to remove documentation and add support with an explanation why
• @tigent creates a new pull request draft that updates the prompt
• It goes into a loop until the updated prompt works for #123 correctly
