Ontoly Software Graph

Use Ontoly when a coding agent needs graph-backed software understanding before searching source files directly.

Ontoly builds a deterministic Software Graph from a TypeScript repository and exposes it through CLI queries, MCP capabilities, and agent skills. The skill teaches workflow only; Ontoly remains the source of truth.

Workflow

Check whether an Ontoly graph already exists in the repository, such as .ontoly/, SoftwareGraph.json, or documented Ontoly scripts.
If the graph is missing and local graph output is appropriate, run ontoly build ..
Check graph diagnostics, trust, semantic coverage, framework detection, and validation before making architecture claims.
Prefer Ontoly CLI or MCP capabilities for architecture summaries, request tracing, dependency analysis, configuration lookup, framework reports, and impact analysis.
Inspect source files only when the graph is missing, incomplete, untrusted for the question, or the user explicitly asks for source-level verification.

Use Cases

Explain repository architecture, module ownership, services, routes, packages, or dependencies.
Trace a request, route, controller, service, provider, dependency, or call chain.
Estimate impact for removing, renaming, or refactoring a symbol, module, package, route, or service.
Review circular imports, dead code, configuration usage, environment variables, or graph diagnostics.

Evidence Rules

Separate graph facts from inference.
Cite exact graph nodes, edges, packages, routes, diagnostics, or query outputs when available.
Treat unresolved imports, low trust, missing framework detection, and validation failures as answer limitations.
Do not claim a relationship exists unless Ontoly reports it or the answer labels it as inferred.

Example Prompts

Use Ontoly to explain this repository's architecture.

Use Ontoly to trace the login flow from route to controller, service, and repository.

Use Ontoly to find what depends on UserRepository and what breaks if it changes.

How to use it

Copy the folder

Take davepoon/ontoly-software-graph from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
