At a glance
Generate comprehensive ontological knowledge graphs in [[wikilinks]] syntax for InfraNodus visualization.
- Works in 2 steps: Topic: Generate comprehensive ontology… → Text: Extract ontological structure from…
- The user requests to create an ontology
- SKILL.md covers Input Types, Entity Generation Principles, Output Format and Relation Codes, plus 6 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Ontology Generator is an agent skill from infranodus/skills. Generate comprehensive ontological knowledge graphs in [[wikilinks]] syntax for InfraNodus visualization. Use when the user requests to create an ontology, extract entities and relationships from text, or generate knowledge graph structures. Handles both topic-based ontology generation and entity extraction from existing text. Output is formatted for direct paste into InfraNodus.com for network visualization and AI-powered gap analysis.
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Knowledge Management, covering Knowledge graphs. The repository describes itself as: Skills to augment LLM thinking process, integrated with InfraNodus insight generation tool.
When your agent uses it
- The user requests to create an ontology
- Extract entities and relationships from text
- Generate knowledge graph structures
Example prompts
- “/ontology-generator”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Topic: Generate comprehensive ontology for a given domain
- Text: Extract ontological structure from provided text
What it can do on your machine
Read from SKILL.md and the folder at commit 8a2a909. 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.
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
Ontology Generator loads about 2.2k tokens when it runs. Until then it costs about 115 tokens; SKILL.md has 681 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 681 words (~2,184 tokens).
“Generate ontological knowledge graphs in InfraNodus format using [[wikilinks]] syntax. Output can be pasted directly into InfraNodus.com to visualize as a network and develop gaps and clusters with AI.”
