The files are empty except some boilerplate code. Could you please suggest what I need to try to fix it. Do I have to include more header files in the SourcesPaths key?

Like I suggested in comments to your commit, you should include TRANSLATOR rules that would accept all methods and types. Everything is ignored by default.

TRANSLATOR: 
  ConstRules: 
    defines: expand
  Rules: 
    global: 
      - {transform: lower}
      - {action: accept, from: "^hb_"}
      - {action: replace, from: "^hb_", to: _}
      - {transform: export}
    const:
      - {action: accept, from: "^HB_"}
      - {action: replace, from: "^hb_", to: _}
    type: 
      - {action: replace, from: "_t$"}
    private:
      - {transform: unexport}
    post-global: 
      - {action: replace, from: _$}
      - {load: snakecase}

Everything seems alright then. After that you'l' be able to specify PtrTips for the methods.
Consult the documentation for that https://github.com/xlab/cgogen/wiki/Translator-config-section.

Actually, I did incorporate the changes you recommended already:
https://github.com/deepakjois/harfbuzz-go/blob/master/harfbuzz.yml

Although, I must admit I don’t what those rules mean. I will read the documentation and try again.

@deepakjois alright. I see many methods have sliced arguments where they're supposed to be pointer-like. So you can set a default ground like

- {target: ".", tips: [sref,sref,sref,sref,sref]}

And then add exceptions where actually you want slices, above that rule.
