{"slug": "agentblackbox-a-policy-gate-and-tamper-evident-audit-log-for-ai-agents", "title": "AgentBlackBox – a policy gate and tamper-evident audit log for AI agents", "summary": "AgentBlackBox launched as a policy gate and tamper-evident audit log that sits between AI agents and the systems they touch, recording each agent's observations, decisions, requests, changes, blocks and executions plus human approvals into a SHA-256 hash chain linked from a GENESIS root, so any edit, insert or delete breaks the chain and is detectable. The tool returns ALLOW, REQUIRE_APPROVAL or BLOCK for proposed actions with matched rules and a recommendation, gates high-risk actions on human sign-off, and generates a one-click audit report per work unit with executive summary, full event log, Print/Save as PDF and JSON export. External agents POST events to /api/events with an API key, while OAuth integrations, billing and banking are intentionally mocked in the MVP until credentials are configured.", "body_md": "AgentBlackBox records what an AI agent saw, decided, requested, changed, blocked, and executed — and who approved it — into a tamper-evident, cryptographically chained audit trail you can prove to a customer, auditor, or regulator.\n\nAgentBlackBox sits between your AI agents and the systems they touch and records a complete, ordered, tamper-evident log of their behavior and the human approvals around it. Each work unit (a task an agent is handling) gets a timeline of events, a policy gate, optional human sign-off, and a one-click audit report.\n\nAutonomous agents now read inboxes, move money, change records, and message customers. When something goes wrong — or a customer, auditor, or regulator asks “what exactly did the AI do, and who approved it?” — you need a provable answer. A tamper-evident hash chain makes the record trustworthy: nothing can be quietly edited after the fact without detection.\n\nEvery event is SHA-256 hashed and linked to the previous one (prevHash → eventHash) from a GENESIS root. Any edit, insert, or delete breaks the chain and is instantly detectable.\n\nRecords what an agent observed, decided, requested, executed, blocked, or errored on — in order, with payloads.\n\nHigh-risk actions gate on a human decision. Approvals and denials are themselves recorded as chained events.\n\nSimulate any proposed action and get ALLOW, REQUIRE_APPROVAL, or BLOCK with the matched rules and a recommendation.\n\nOne-click, investor-ready audit report per work unit with executive summary, full event log, Print / Save as PDF, and JSON export.\n\nExternal AI agents POST events to /api/events with an API key. Mock connectors (Gmail, Slack, Drive, Browser) show the future surface.\n\nWalk the full loop in a couple of minutes:\n\nStart a new tamper-evident timeline for a task an agent is handling.\n\nRun a proposed action through the policy engine to see ALLOW / REQUIRE_APPROVAL / BLOCK.\n\nAdd an observation, decision, or tool call — it chains onto the timeline.\n\nDecide on a pending high-risk request; the decision is recorded as an event.\n\nSee the executive summary, full event log, and hash-chain status.\n\nExternal OAuth integrations, billing, and banking are intentionally mocked in this MVP until credentials are configured.\n\nDownload the signed-style JSON record or save a clean PDF for an investor or auditor.", "url": "https://wpnews.pro/news/agentblackbox-a-policy-gate-and-tamper-evident-audit-log-for-ai-agents", "canonical_source": "https://agent-blackbox-five.vercel.app/demo", "published_at": "2026-10-18 07:25:01+00:00", "updated_at": "2026-10-18 07:44:20.982035+00:00", "lang": "en", "topics": ["ai-agents", "ai-safety", "ai-policy", "developer-tools"], "entities": ["AgentBlackBox", "Gmail", "Slack", "Google Drive"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/agentblackbox-a-policy-gate-and-tamper-evident-audit-log-for-ai-agents", "markdown": "https://wpnews.pro/news/agentblackbox-a-policy-gate-and-tamper-evident-audit-log-for-ai-agents.md", "text": "https://wpnews.pro/news/agentblackbox-a-policy-gate-and-tamper-evident-audit-log-for-ai-agents.txt", "jsonld": "https://wpnews.pro/news/agentblackbox-a-policy-gate-and-tamper-evident-audit-log-for-ai-agents.jsonld"}}
