Caveat verdict
hookflo-tern
Accesses credentials AND makes external network calls
Webhook handling reference skill for the Hookflo/Tern library covering HMAC verification, replay attack prevention, and framework integration patterns; optional secrets (STRIPE_WEBHOOK_SECRET etc.) are used only for their stated webhook verification purpose.
Automated static analysis — not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.
What it does
These are capability combinations: each listed behavior occurs in the skill, but Caveat detects co-occurrence — it does not verify that one flows into another. Read the code to confirm a live chain.
