Semantic Core Builder
Build an evidence-labeled semantic core and crawlable site structure from keyword harvests, existing content, or user-provided search-demand data. Use before SEO/LLM site architecture, concept prototypes, paid traffic planning, IA, or public-site redesign decisions.

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Semantic Core Builder
This skill turns raw keyword/search inputs into a structured semantic core. It hands the result to seo-llm-site-architect, concept-prototyper, and later design/implementation skills.
Operating Modes
build: createreports/semantic-core.jsonanddocs/site-structure.md.merge: merge existing-site keywords, user-provided terms, and harvested demand.audit: review a semantic core for missing provenance, duplicate clusters, or weak intent mapping.
Required Workflow
- Read [references/semantic-core-contract.md](references/semantic-core-contract.md).
- Load
reports/keyword-harvest.jsonor a user-provided equivalent. - Cluster keywords by intent and topic; label any LLM grouping as
Inference. - Produce cluster records: intent, priority, canonical URL candidate, page type, evidence, and confidence.
- Write machine-readable
reports/semantic-core.jsonand human-readabledocs/site-structure.md. - Hand off to
concept-prototyperandseo-llm-site-architect.
Safety And Evidence
- Do not invent search volume or SERP facts.
- If no real SERP/source evidence exists, label the output as
ManualorInference. - Do not bury conflicts; record cannibalization, unclear intent, or missing evidence.
