That’s Not Evidence. **[Medium](https://daily.dev/sources/medium_js)** · 14 min read · 3 upvotes · 0 comments ## Summary Autonomous AI agents can now build, validate, and publish data pipelines end to end, but 'pipeline healthy' status checks don't prove correctness. A syntactically valid, operationally healthy pipeline can still leak prohibited fields, mishandle deletes, preserve values while destroying their semantic meaning, or misinterpret ambiguous business intent. This is framed as a test oracle problem: an agent that generates, implements, and validates its own interpretation only proves internal consistency, not correctness against reality. The piece proposes a layered verification model (specification, transport, behavioral correctness, data correctness, policy, business intent) and six concrete verification gates, using Estuary's Agent Skills, flowctl CLI, and schema-evolution/deletion semantics as a working example, arguing that as generation gets cheaper, independent verification becomes the real bottleneck. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why isn't a green health check enough to trust a data pipeline built by an AI agent? A green check only proves the configuration is syntactically valid and data moved, not that the pipeline is correct. Correctness has separate layers — transport, behavioral correctness (deletes, retries, schema changes), policy compliance, data correctness, and business intent — and passing one layer never proves the layer above it, since technical correctness is not transitive. _Anyone shipping agent-built pipelines can weigh this layered verification argument on daily.dev before trusting a single 'healthy' status._ ### What is the test oracle problem when an AI agent both builds and validates its own pipeline? When the same agent interprets a requirement, generates the pipeline, generates the validation, and evaluates whether validation passed, the test only proves the agent implemented its own interpretation correctly, not that the interpretation itself was right. An independent source of truth — a contract, invariant, policy, or human-approved rule — is needed outside the generation loop to define what correct actually means. _Teams deciding how much to trust agent self-verification can use daily.dev to dig into this oracle problem in agentic pipelines._ ### How can soft-delete semantics in a CDC pipeline cause a deleted customer to remain accessible downstream? With soft-delete configured, a deleted record still exists downstream but gets tagged with metadata such as _meta op equal to d rather than being physically removed. If the consuming application's retrieval query does not filter on that deletion marker, the deleted customer remains visible to that application even though the pipeline itself processed the delete exactly as configured. _Engineers debugging stale deleted records downstream can review this soft-delete gotcha on daily.dev before it reaches production._ ## Similar posts on daily.dev - [Code that runs is not code that's correct: 4 ways to trust an AI-written data pipeline](https://daily.dev/posts/code-that-runs-is-not-code-that-s-correct-4-ways-to-trust-an-ai-written-data-pipeline-6o63ugcr5) · MotherDuck · 1 upvotes · 0 comments - [Your CI/CD Pipeline Is Not Ready To Ship AI Agents](https://daily.dev/posts/your-ci-cd-pipeline-is-not-ready-to-ship-ai-agents-imnreunmi) · The New Stack · 0 upvotes · 0 comments - [Most 'AI Agents' Are Just If-Statements in a Trench Coat](https://daily.dev/posts/most-ai-agents-are-just-if-statements-in-a-trench-coat-txevbbjv0) · DEV · 1 upvotes · 0 comments - [Agentic Verification](https://daily.dev/posts/agentic-verification-tekwi3ces) · Elevate · 1 upvotes · 0 comments --- Tags: [#devops](https://daily.dev/tags/devops), [#testing](https://daily.dev/tags/testing), [#ai-agents](https://daily.dev/tags/ai-agents), [#data-engineering](https://daily.dev/tags/data-engineering) [View this post on daily.dev](https://daily.dev/posts/your-ai-agent-says-the-pipeline-works-that-s-not-evidence--06xfqlqdb) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Your AI Agent Says the Pipeline Works.
