Is Kamil Az-Ziyarat reliable?

Sahib Kamil Az-Ziyarat writes:

We acknowledge that we cannot encompass everything which has been narrated from them about this topic (ziyarah) or about any other topic (for that matter).  Furthermore, I have only narrated that which was reported to me by the trustworthy ones from among our companions – may Allah’s Mercy be upon them – and I did not include anything which has been reported by unknown or unreliable sources who are not well-known for their knowledge and narrations.

📚Kamil Az-Ziyarat P19-20

Sahib Al-Wasail writes:

“And also Ja’far bin Muhammad bin Qulawayh has testified that the narrators of Kamil al-Ziyarat are reliable and trustworthy. His explicit statement in the beginning of Kamil al-Ziyarat is more expressive and frank than Ali bin Ibrahim’s (about authenticity of his book.”
