Ontoly Software Graph

Use this skill when the user asks Codex to understand a TypeScript repository's architecture, dependency graph, request flow, service ownership, configuration usage, impact radius, package topology, or security-sensitive code paths.

Ontoly is a deterministic Software Graph compiler. It does not answer questions with AI. It builds graph evidence that Codex can query before falling back to source search.

Workflow

1. Check whether .ontoly/SoftwareGraph.json exists.

2. If the graph is missing or stale, ask before installing dependencies or writing generated graph files. Then run:

   pnpm add -D @0xsarwagya/ontoly-cli
   pnpm ontoly build .
   

3. Inspect graph quality before answering:

   pnpm ontoly coverage .
   pnpm ontoly stats .
   

4. Prefer Ontoly graph queries before repository-wide source search:

   pnpm ontoly architecture --json
   pnpm ontoly report dependencies --format markdown
   pnpm ontoly report routes --format markdown
   pnpm ontoly query impact <node-id>
   pnpm ontoly trace <node-id-or-name>
   

5. Start Ontoly MCP when the environment supports MCP-backed tools:

   pnpm ontoly mcp
   

6. Use source files only when the graph is missing, stale, low confidence, or insufficient for the question.

Common Questions

• "Explain this repository."
• "Which service owns authentication?"
• "Trace the login flow."
• "What breaks if I remove this repository/service/function?"
• "Which packages depend on this module?"
• "Where is this environment variable read?"
• "Which routes are protected by auth?"

Evidence Rules

When answering, cite graph evidence:

• graph hash
• node ids
• relationship types
• source spans when available
• diagnostics or confidence warnings
• fallback reason if source files were inspected

Never claim certainty beyond Ontoly evidence. If graph coverage is incomplete, say exactly which part is inferred or unresolved.

Official Ontoly Skills

Ontoly publishes task-specific Agent Skills in its own repository. To inspect or install them with the open skills CLI:

npx skills add 0xsarwagya/ontoly --list
npx skills add 0xsarwagya/ontoly --skill architecture-review
npx skills add 0xsarwagya/ontoly --skill impact-analysis
npx skills add 0xsarwagya/ontoly --skill request-tracing

Use those official skills when the task maps directly to one of their workflows.
