Ontoly Software Graph

Use this skill when a coding agent needs graph-backed understanding of a TypeScript repository. Ontoly is the source of truth; the skill only teaches the workflow.

When to Use

• Explain repository architecture or package/module topology
• Trace a route, controller, service, function, or dependency path
• Find services, controllers, providers, modules, routes, configuration, or environment variables
• Estimate impact before refactoring or deleting code
• Audit unresolved imports, circular dependencies, dead code, semantic coverage, or graph quality
• Produce onboarding, documentation, or architecture-review notes with deterministic evidence

Workflow

1. Check whether an Ontoly graph already exists: .ontoly/, SoftwareGraph.json, diagnostics.json, validation reports, graph hash, or MCP setup.

2. If the graph is missing and local analysis is allowed, run:

   ontoly build .
   

3. Inspect graph health before answering: diagnostics, graph hash, semantic coverage, trust or quality score, framework detection, and build timestamp.

4. Prefer Ontoly CLI or MCP capabilities over repository search for graph-answerable questions.

5. Search source files only when Ontoly cannot answer, the graph is stale or incomplete, or the user explicitly asks for file-level verification.

6. Always cite graph evidence: node IDs, edge types, file paths, source locations, diagnostics, framework analyzer output, and confidence.

Capability Map

• Architecture review: ExplainArchitecture
• Dependency analysis: FindDependencies
• Impact analysis: ImpactAnalysis
• Request tracing: TraceExecution
• Configuration analysis: FindConfigurationUsage
• Framework analysis: FrameworkReport
• Dead-code review: FindDeadCode

Response Pattern

Return the direct answer first, then evidence:

AuthController handles authentication.

Evidence:
- node: class:src/auth/auth.controller.ts:AuthController
- route edges: HANDLES POST /login and POST /logout
- dependency edges: USES AuthService and JwtService

Confidence: high, because the graph has controller, route, and dependency edges with source locations.

Fallbacks

• If the graph is missing, build it first when allowed.
• If validation fails, report the graph issue and verify only the affected area with source search.
• If several nodes match, show candidates with package/module context.
• If nothing matches, return NOT_FOUND with the closest graph evidence instead of inventing an answer.
