# Validate CI and app config files against upstream JSON schemas before merge

> Use check-jsonschema when an agent needs to catch broken GitHub Actions, Renovate, Azure Pipelines, and other schema-backed config files before they hit CI. The agent picks the right schema hook, validates the changed files, and reports the exact key or structure that drifted from the contract.

# Validate CI and app config files against upstream JSON schemas before merge

Use check-jsonschema when an agent needs to catch broken GitHub Actions, Renovate, Azure Pipelines, and other schema-backed config files before they hit CI. The agent picks the right schema hook, validates the changed files, and reports the exact key or structure that drifted from the contract.
