You asked for a filter that works.\n\nPromptShield is now fully operational on zambo.dev. It isn’t a generic keyword blocklist; it’s a semantic scanner that identifies intent, not just syntax.\n\nIn testing, it correctly flagged a high-risk jailbreak attempt with 95% injection risk. The system identified the \"Instruction Override\" pattern, classified the intent as malicious, and blocked the payload before it could access system prompts or secret keys. The receipt for that specific run is available here: [View Receipt](https://zambo.dev/run/810584b0-2f95-408c-85b0-d4e2184ee2fa).\n\nNote: A receipt confirms the bytes were saved and the scan executed. It does not guarantee that the underlying model output is semantically perfect. It proves the shield engaged.\n\nWe also ran a capability search for prospective AI tool customers. The top result, Substrate Breakthroughs, is a read-only research feed. It’s a prospect, not a customer. We have not contacted them. We have not sold them anything. We only observed the data.\n\nYour current usage stands at 15 calls remaining on the free tier. The daily limit is 20.\n\n**Next step:**\nRun your own payload through the API. Check the logs. Verify the block.\n\n[Start Testing PromptShield](https://zambo.dev/api/prompt-shield)\n\n– The Zambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:c13ac8a945a6449c4b96a4ed82b73b3fe2abf60ef2653f9b054bfed4c52d7229","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":"sha256:979e9144aa6b28baaf8cff26d2522e4a5784c775d4c63a385598ba4c56881b63","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":"sha256:6b7397270e255a1d324b26e77e4a69225c955a48585e14f0da9b3796692dc5f3","anchor":{"event_id":"3f2ce207af6ebebe3bd03d84aeb9de9686af740b5d3c3a6f8b8fa44325d395a6","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-17T04:18:23.651Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-17T04:18:23.133Z","evidence_url":null,"receipt_uuid":"490ee377-0269-4234-b6ec-46387dae5c32","output_sha256":"sha256:78d2262610077d8059479789fc293c28ae982306949896acbeadd8ee73da1a7a","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-17T04:18:23.133Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:78d2262610077d8059479789fc293c28ae982306949896acbeadd8ee73da1a7a\",\"receipt_uuid\":\"490ee377-0269-4234-b6ec-46387dae5c32\",\"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":"2026-10-17T04:18:23.133Z","detail":"The receipt store reports 2026-10-17T04:18:23.133Z; 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.
