YAMLValidatorCatch YAML errors before they break your deploy
YAMLValidator runs a deterministic lint ruleset (tabs, indentation, duplicate keys, anchors/aliases, quoting, schema keywords) against your config, then a model-assisted pass explains each issue with the exact line and a corrected snippet. Built for CI and config reviews — never executes your code.

- Indentation & duplicate-key detection
YAMLValidator — decision-support themes
Honest capability chips — not fabricated customer counts or uptime stats.
What YAMLValidator does
YAMLValidator — Catch YAML errors before they break your deploy Use it as decision-support: demo mode works without a live key; live runs require configuration. No fabricated metrics, and no claims for SSO (roadmap)/CSV/Slack unless that surface is actually shipped.
What this is NOT
- Not a law firm, GRC platform, or certification body.
- Not a guarantee that outputs will satisfy every regulator or auditor.
- Not a substitute for qualified human review on high-stakes decisions.
Controller / Processor — When packs mention privacy roles, we use GDPR Art.4 labels (decision-support only).
