We built it.\n\nPromptShield is officially live. It’s a semantic analysis engine that scans prompts for injection, jailbreaks, and policy bypasses before they touch your model. No fuzzy matching. No guesswork. Just binary, reliable safety checks.\n\nIn our initial stress test, the system flagged a complex instruction override attempt with 95% confidence. It correctly identified the attack vector, isolated the risky payload, and blocked execution. The receipt confirms the exact bytes processed, ensuring you know precisely what was scanned and why it was flagged.\n\nThis isn’t a beta. The API is stable, the logic is hardened, and the documentation is ready.\n\n**The CTA:**\nTest your own worst-case prompt against PromptShield now.\n1. Visit https://zambo.dev/api/prompt-shield\n2. Run a free scan (no credit card required).\n3. Check the receipt URL to verify the detection logic.\n\nIf the scan misses a known threat, reply to this email. I’ll fix it personally.\n\nIf it works as intended, you know what to do.\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:3a2136f10a112f7795432a9cc55850c2fb29d863f7f046e3bcdddb3279e554d4","input_hash_layout":"zambo-json-sorted-keys-utf8-v1","free_used":0,"free_remaining":0,"free_limit":0,"signal_handle":null,"tool":{"name":"write","version":"4.0.0","scope":"public"},"caller":{"type":"session","id":"sha256:0935e20eebe4d3c7235feb326e80f431c4d7cc59cbcacfca12756c19c9f83469","label":"zambo-home-demo","label_source":"caller_reported"},"side_effects":{"declared":["none"],"schema_version":"zambo-side-effects/1","declaration_hash":"sha256:45aad38f3aa982b9aafe92ecb416ebe98791eddbaf8ab6df0bd08605b7c1bfee"},"evidence_sha256":null,"evidence_url":null,"evidence_byte_length":null,"evidence_content_type":null,"evidence_source_url":null,"evidence_status":"no_upstream_bytes_captured","external_evidence":[],"provenance":null,"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:36c975e4a4414b990cee28652698effd2242308ec2e90f7203b12fd555a764bc","anchor":{"event_id":"b8b61552d01aacda197d2f04058d3e86a42f9c3d3352cc30a5a9820294619c50","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-19T14:38:10.695Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-19T14:38:09.207Z","evidence_url":null,"receipt_uuid":"4a6968e5-9a7c-49cd-acf3-ca8dcb7b7804","output_sha256":"sha256:5d5b7611f0ea7fb9734da27f42f69e8cf7bebf3464ddcde00e3b6aae213bd2b4","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-19T14:38:09.207Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:5d5b7611f0ea7fb9734da27f42f69e8cf7bebf3464ddcde00e3b6aae213bd2b4\",\"receipt_uuid\":\"4a6968e5-9a7c-49cd-acf3-ca8dcb7b7804\",\"schema_version\":\"zambo-receipt-anchor/1\"}"},"receipt_profile":"zambo-hosted-receipt/1","schema_url":"https://zambo.dev/aer-1/hosted-profile.schema.json","api_version":1,"verification_scope":"separate_sha256_commitment_and_provenance_binding_checks","checks":{"commitment_matches":{"label":"SHA-256 commitment","passed":true,"status":"pass","detail":"The exact decoded canonical bytes match the stored SHA-256 output hash."},"canonical_payload_matches":{"label":"Canonical payload reconstruction","passed":true,"status":"pass","detail":"The stored output and known call context reconstruct the exact canonical bytes."},"provenance_binding":{"label":"Provenance claim binding","status":"pass","passed":true,"detail":"The metadata claim is consistent with the verified receipt bytes; issuer is not authenticated."},"metadata_binding":{"label":"AER-1 metadata hash","status":"pass","passed":true,"detail":"metadata_hash matches the canonical metadata block."},"signature":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"No Ed25519 signature or pinned signing key was checked."},"chain":{"label":"Receipt chain (not checked)","passed":false,"status":"not_checked","detail":"No append-only receipt-chain proof was checked."},"issued_by_zambo_dev":{"label":"Issuer authentication","passed":false,"status":"not_checked","detail":"A zambo.dev receipt URL does not authenticate the issuer; no pinned signature or trusted issuer key was checked."},"immutable_log_timestamp":{"label":"Stored timestamp","passed":true,"timestamp":"2026-10-19T14:38:09.207Z","detail":"The receipt store reports 2026-10-19T14:38:09.207Z; immutability is not checked here."},"receipt_schema_version":"0.4","signature_valid":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"Compatibility field only.
