+  signals.

+
+# Signal Taxonomy Skill
+
+## When to Use
+- Normalizing multiple provider outputs into a unified schema.
+- Rolling out new intent topics, enrichment attributes, or scoring dimensions.
+- Auditing lineage + compliance requirements.
+
+## Framework
+1. **Schema Definition** – fields, datatypes, required/optional flags.
+2. **Topic & Attribute Mapping** – align provider-specific attributes to canonical names.
+3. **Versioning** – maintain change logs, effective dates, and migration steps.
+4. **Validation Rules** – min/max values, allowed lists, dependency rules.
+5. **Documentation** – publish data dictionary + lineage diagrams.
+
+## Templates
+- Data dictionary sheet (field, description, source, owner).
+- Topic mapping table by provider.
+- Migration checklist for schema changes.
+
+## Tips
+- Keep names human-readable for GTM teams but consistent with data warehouse standards.
+- Tag every field with owner + refresh cadence.
+- Pair with `identity-resolution` to ensure IDs and linkages stay consistent.
