Validate agent output against declared domain rules and ground truth before trusting it downstream. Trigger after any agent produces output that will be used in a decision, stored persistently, or passed to another agent.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Domain Validator > **Agent output is a hypothesis. Domain validation is the test.** An agent that produces output without validation is a system that produces hallucinations at scale. The domain validator is the check that separates "the agent said so" from "it is true." ## When to use - After an agent produces output that feeds a downstream system or human decision - When an agent has reasoned over domain-specific data (financial figures, medical records, legal clauses, system configurations) - Before persisting agent-generated content to a database or document store - When an agent output will be presented to an end user as factual ## Procedure 1. **Declare the domain rules** — before running any validation, the domain rules must be explicit: - What are the invariants? (e.g. "a date range must have start < end", "a price must be positive", "a configuration must reference an existing resource") - What are the allowed value ranges or enumerations? - What is the ground truth source? (database record, API response, regulatory document, schema definition) …

How to install
mdr add jpantsjoha/ai-native-developer-experience/domain-validator@sha256:75cfc3b599db7351The line at the top of this page pins the label git:20260807.c64e31f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
