What problem does it solve? Managing a Thai product category hierarchy is error-prone: nodes get created without enough keywords, embeddings are forgotten after inserts, and edits to taxonomy_nodes silently break classification for thousands of products. This Skill provides the schema knowledge, design rules, and safe workflows to design, extend, and modify a Thai product taxonomy without regressing classification accuracy. ## Core Features & Use Cases - Taxonomy Hierarchy Design: Enforces a 3-level structure (L1 main, L2 sub, L3 specific) with rules such as minimum 3 Thai keywords per node and no ambiguous catch-all categories. - Hybrid Classification Guidance: Documents the 60% keyword / 40% embedding (384-dim vector, cosine distance) algorithm and how to tune keyword_rules priorities. - Safe Modification Workflow: Provides blast-radius SQL checks (product counts, child nodes) and backup thresholds before editing or deleting nodes. - Use Case: You need to add a new "นมสด" (fresh milk) category under the dairy parent node. The Skill walks you through checking the parent hierarchy, defining Thai keywords and brand aliases, inserting the node, generating its embedding via the local FastAPI server, and verifying classification with a test product name. ## Quick Start Ask the assistant to add a new Thai product category to the taxonomy, and it will check the parent hierarchy, define keywords, insert the node, generate its embedding, and test classification.
