SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve? In an ecosystem with dozens of AI skills, choosing which skill to activate for a given request is error-prone: ambiguous prompts trigger the wrong skill, or too many skills activate at once and waste context tokens. This Skill acts as the entry point for every substantive request, classifying intent and selecting the minimum sufficient skill set. ## Core Features & Use Cases - Intent classification and routing: Classifies requests as simple, complex, or ambiguous, then maps them to skills via semantic meaning rather than literal keyword matching, with confidence scoring thresholds. - Two-level domain routing: Routes first to a domain node (L1), then to a minimal skill set inside that node (L2), loading only one node manifest instead of every SKILL.md. - Multi-skill coordination: Defines handoff protocols, parallel activation rules, and typed-context passing between skills, with validation of combined outputs. - Use Case: A user asks to "build a validated n8n workflow and remember the session" — the router activates n8n-orchestrator and continuation-memory in parallel, then validation-mesh on the combined output, instead of loading all 28 skills. ## Quick Start Ask the assistant to route an ambiguous or multi-part request, for example: "Route this request: build a validated automation workflow and save our session state."

Frequently Asked Questions about semantic-router

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I route a request to the right AI skill automatically?▼

Submit any substantive request and the router classifies it as simple, complex, or ambiguous, then matches intent to skill descriptions semantically. Simple tasks activate one skill or none; complex tasks activate a minimal coordinated chain; ambiguous tasks trigger exactly one clarifying question.

What is semantic intent matching for skill selection?▼

Semantic matching compares the meaning of a request against skill triggers rather than requiring exact keyword matches. Synonyms and paraphrases activate the same skill, so users do not need to know the precise trigger phrases listed in skill descriptions.

How does confidence scoring work in skill routing?▼

Each candidate skill receives a confidence score based on intent signals. Scores of 0.80 or higher activate without questions, 0.50 to 0.79 activate with an explanatory comment, and below 0.50 the router asks the user one clarifying question before proceeding.

Can multiple AI skills run in parallel on one request?▼

Yes, skills activate in parallel when their tasks are independent and each maps clearly to its own skill. If one skill's output feeds another, they run sequentially with structured context handoffs, and a validation skill checks the combined result.

When should I not use a semantic router for skill selection?▼

Skip the router when a request clearly maps to a single obvious skill — activate that skill directly. It also does not handle multi-agent topology mechanics, kernel-level agent activation, or heavy meta-orchestration, which belong to dedicated orchestration skills.
