comparison-taxonomy

Maintain the comparison schema across the canon.

Use this skill when the task is to define or refine axes, tags, categories, relevance tiers, or normalization rules.

Load First

• Read comparison/COMPETITOR_GUIDE.md.
• Read comparison/TRACKING.md.
• Read comparison/_template/index.md.

Inspect a few real competitor records before changing the schema.

What This Skill Owns

• comparison axes
• tag vocabulary
• category and segment naming
• relevance tiers
• stable field naming
• normalization rules across competitor records

Taxonomy Workflow

1. Identify the schema pressure:
   • new website filter need
   • repeated inconsistency across competitors
   • missing dimension that keeps showing up in research
2. Prefer the smallest change that resolves the pressure.
3. Decide whether the concept belongs in:
   • a stable field
   • a comparison axis
   • a tag
   • editorial prose only
4. Update all schema authorities together:
   • guide
   • template
   • tracker if statuses or priorities are affected
5. Note migration implications for existing records.

Taxonomy Rules

• protect schema stability
• prefer explicit fields over overloaded tags
• do not add tags that duplicate stable fields
• do not create new axes unless they will matter across multiple competitors
• do not solve a publishing problem by polluting canonical schema without clear long-term value

Output Expectations

When making taxonomy changes, always state:

• what changed
• why it was necessary
• which existing records will need normalization later
