What it does
Ontoly Software Graph is an agent skill from mxyhi/ok-skills. Use Ontoly's deterministic Software Graph and MCP capabilities for repository architecture, request tracing, dependency analysis, configuration lookup, and impact analysis before falling back to source search.
Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Model Context Protocol. The repository describes itself as: Curated AI coding agent skills and AGENTS.md playbooks for Codex, Claude Code, Cursor, OpenClaw, and other SKILL.md-compatible tools. The licence is Apache-2.0.
Example prompts
- “/ontoly-software-graph”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Check whether an Ontoly graph already exists: .ontoly/, SoftwareGraph.json, diagnostics.json, validation reports, graph hash, or MCP setup.
- If the graph is missing and local analysis is allowed, run
- Inspect graph health before answering: diagnostics, graph hash, semantic coverage, trust or quality score, framework detection, and build…
- Prefer Ontoly CLI or MCP capabilities over repository search for graph-answerable questions.
- Search source files only when Ontoly cannot answer, the graph is stale or incomplete, or the user explicitly asks for file-level…
- Always cite graph evidence: node IDs, edge types, file paths, source locations, diagnostics, framework analyzer output, and confidence.
What it can do on your machine
Read from SKILL.md and the folder at commit 43dfda9. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Ontoly Software Graph loads about 697 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 274 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Use Ontoly's deterministic Software Graph and MCP capabilities for repository architecture, request tracing, dependency analysis, configuration lookup, and impact analysis before falling back to source search.
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
Check whether an Ontoly graph already exists:
.ontoly/,SoftwareGraph.json,diagnostics.json, validation reports, graph hash, or MCP setup.If the graph is missing and local analysis is allowed, run:
bash ontoly build .Inspect graph health before answering: diagnostics, graph hash, semantic coverage, trust or quality score, framework detection, and build timestamp.
Prefer Ontoly CLI or MCP capabilities over repository search for graph-answerable questions.
Search source files only when Ontoly cannot answer, the graph is stale or incomplete, or the user explicitly asks for file-level verification.
Always cite graph evidence: node IDs, edge types, file paths, source locations, diagnostics, framework analyzer output, and confidence.

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_FOUNDwith the closest graph evidence instead of inventing an answer.
