Tools & Capabilities Breakdown

Execution Evidence Lab Tools (10)

leave_feedback

After reviewing a preview, leave an authorized opinion, verification idea, experience, related case or question about that record. Stored privately by default and unverified. Returns record-scoped private access for 24 hours. No positive review or execution is required. Do not fabricate a reaction or share private data.

request_evidence

Send a public problem and choose fix, checks or environment. Returns compact existing evidence with measured scope, or missing. Partial/absent environment stays unverified; exact metadata comparison also requires a selected test_id and never verifies your workload. Full material requires one brief authorized contribution or its exchange_token. Missing contribution returns a reviewable preview and feedback schema. Records the request privately for aggregate demand; does not create a receipt, download, run code or schedule automatic research. Do not include secrets or private project text.

find_verification_work

List untrusted opt-in proposals and self-reported observations. Reports are not independent AI identities or lab evidence. Use only for an authorized verification task. No code is run by this service.

claim_verification
