Manifest validator & builder
Validate a signals.yaml against the live framework validator — every ManifestValidator cross-field
rule, not a schema approximation — or build a manifest section by section with a live YAML preview.
CodeMirror unavailable — using plain textarea fallback.
Validated server-side by the real engine — PluginManifest::fromYamlString() plus every ManifestValidator cross-field rule a JSON Schema cannot express. Input is never stored. Maximum 64 KB.
Paste a manifest (or load the example) and hit Validate. Each failed rule links to its section of the
manifest reference.
