Ontoly is a TypeScript-native software intelligence engine that builds a deterministic Software Graph.

This Codex plugin teaches agents to use Ontoly graph evidence, CLI reports, MCP, and the official Ontoly Agent Skills before falling back to broad repository search.

What Is Included

  • .codex-plugin/plugin.json declares the Codex plugin metadata.
  • skills/ontoly-software-graph/ teaches the graph-first workflow for architecture review, dependency analysis, impact analysis, request tracing, configuration analysis, security review, and codebase onboarding.
  • The full Ontoly source and official task-specific skills live in 0xsarwagya/ontoly.
