Nobulex receipt layer plugin merged - tamper-evident audit trail for Dify agents

[arian-gogani]

The Nobulex receipt layer plugin just merged into the official dify-plugins repository (PR #2500).

What it does: adds Ed25519-signed receipts to every Dify agent tool call. Each receipt is content-derived (the identifier is a SHA-256 hash of the action fields), so any third party can verify what your agent did without trusting you or your logs.

Tools included:

• sign_receipt - sign a receipt for any tool call
• verify_receipt - verify a receipt's signature and action_ref
• get_trust_score - check an agent's accumulated trust score
• export_article12 - export an EU AI Act Article 12 evidence package

Install: search for "nobulex" in the Dify plugin marketplace.

Why you might want this: if you run Dify agents that touch customer data, make payments, or do anything a client might ask you to prove later, receipts give you a tamper-evident audit trail that holds up to independent verification.

If anyone tries it, I would genuinely like to hear what works and what breaks. Feedback welcome.

pip install nobulex for the standalone SDK.
