About OASF Classification

Agents are automatically classified using a multi-strategy approach:

  1. Metadata extraction — skills and domains from the agent's registration JSON services[].skills/domains
  2. LLM classification — AI-powered analysis of the agent description (DeepSeek, OpenAI, or Claude)
  3. Keyword matching — rule-based fallback when no LLM is available

Classification follows strict validation rules: descriptions must be at least 20 characters, error messages are filtered out, and the system prefers no classification over an incorrect one.
