+
+            `cargo vet` has failed in this PR. Please run `cargo vet --locked` locally to check for new or updated unvetted dependencies.
+            Details about the vetting process can be found in [supply-chain/README.md](../blob/main/supply-chain/README.md)
+
+            ## If the unvetted dependencies are not needed
+            Please modify Cargo.toml file to avoid including the dependencies.
+
+            ## If the unvetted dependencies are needed
+            Post a new comment with the questionnaire below to the PR to help the auditors vet the dependencies.
+            After the auditors have vetted the dependencies, the PR will need to be rebased to pick up the new audits and pass this check.
+
+            ### Copy and paste the questionnaire as a new comment and provide your answers:
+
+            **1. What crates (with version) need to be audited?**
+
+            **2. How many of the crates are version updates vs new dependencies?**
+
+            **3. To confirm none of the already included crates serve your needs, please provide a brief description of the purpose of the new crates.**
+
+            **4. Any extra notes to the auditors to help with their audits.**
