Verify File Attestation Certificate
Upload a file and its attestation certificate, then cryptographically verify that the certificate is authentic and the file has not been tampered with. Uses post-quantum ML-DSA-65 signature verification. Perfect for confirming software release integrity, validating compliance evidence, or verifying any file that was previously attested.
Upload the Original File
Goal: Ask the user for the original file they want to verify. Upload it using the File Management tool. | Inputs: The user provides the file they want to verify — a software release, document, archive, or any artifact that has an attestation certificate. | Outputs: A file_id from File Management after uploading the file. | Constraints: The file must be uploaded to File Management using upload_standard before proceeding. Save the returned file_id. | Success criteria: The file is uploaded and a file_id is returned.
Upload the Attestation Certificate
Goal: Ask the user for the attestation certificate JSON file. Upload it using the File Management tool. | Inputs: The user provides the attestation certificate JSON file they received from the attestation issuer. | Outputs: A file_id for the attestation certificate from File Management. | Constraints: The certificate must be a JSON file. Upload it using File Management upload_standard. Save the returned file_id as the attestation_file_id. | Success criteria: The attestation certificate JSON is uploaded and a file_id is returned.
Verify Attestation
Call verify_attestation with the file_id from the original file upload and the attestation_file_id from the certificate upload. Report the result clearly: if accept is true, the file is verified authentic. If accept is false, list the failed_checks and explain what each failure means.

What the agent will follow (tools, prompts, and workflow steps).
1. Apply the following prompt: Goal:
Ask the user for the original file they want to verify. Upload it using the File Management tool.
Inputs:
The user provides the file they want to verify — a software release, document, archive, or any artifact that has an attestation certificate.
Outputs:
A file_id from File Management after uploading the file.
Constraints:
The file must be uploaded to File Management using upload_standard before proceeding. Save the returned file_id.
Success criteria:
The file is uploaded and a file_id is returned.
2. Apply the following prompt: Goal:
Ask the user for the attestation certificate JSON file. Upload it using the File Management tool.
Inputs:
The user provides the attestation certificate JSON file they received from the attestation issuer.
Outputs:
A file_id for the attestation certificate from File Management.
Constraints:
The certificate must be a JSON file. Upload it using File Management upload_standard. Save the returned file_id as the attestation_file_id.
Success criteria:
The attestation certificate JSON is uploaded and a file_id is returned.
3. Call tool: Quantum-Safe File Attestation (Verify Attestation).
Instructions:
Call verify_attestation with the file_id from the original file upload and the attestation_file_id from the certificate upload. Report the result clearly: if accept is true, the file is verified authentic. If accept is false, list the failed_checks and explain what each failure means.
Parameters:
{"action": "verify_attestation"}
4. Apply the following prompt: Goal:
Present the verification result to the user in clear, non-technical language.
Inputs:
The verification report from the attestation tool including accept, failed_checks, manifest_sha256, and signer_public_key_hex.
Outputs:
A clear statement of whether the file is verified or not, with explanation of what was checked.
Constraints:
If accept is true, confirm the file is authentic and untampered. If accept is false, explain each failed check in plain language. Never overstate what verification means — it proves the file matches what was signed, not that the contents are safe or correct.
Success criteria:
The user understands whether their file is verified and what that means.Agent Reviews
