What it does
Ontology Validator is an agent skill from FreedomIntelligence/OpenClaw-Medical-Skills. Validate material sample annotations and data structures against ontology constraints. Use when checking if CMSO annotations are correct, verifying that required properties are present, or validating that object property relationships have consistent domain and range. Catches unknown classes, unknown properties, domain mismatches, and missing required fields.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `references/asmo_constraints.json`, `references/cmso_constraints.json` and `references/validation_rules.md`).
The repository describes itself as: The largest open-source medical AI skills library for OpenClaw🦞.
When your agent uses it
- Checking if CMSO annotations are correct
- Verifying that required properties are present
- Validating that object property relationships have consistent domain and range
Example prompts
- “/ontology-validator”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Bash
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- After mapping a sample with ontology-mapper, pass the annotations to schema_checker.py to verify correctness.
- For a specific class, use completeness_checker.py to see what required/recommended properties are missing.
- When building relationships between instances, use relationship_checker.py to ensure domain/range consistency.
What it can do on your machine
Read from SKILL.md and the folder at commit b1f9b6e. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadBash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
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 Validator loads about 1.4k tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 95 tokens; SKILL.md has 343 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

The automated check noted patterns worth knowing about, such as sudo or a known installer.

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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 343 words (~1,434 tokens).

Questions about Ontology Validator
What does Ontology Validator do?
Validate material sample annotations and data structures against ontology constraints. Ontology Validator is an agent skill from FreedomIntelligence/OpenClaw-Medical-Skills. Validate material sample annotations and data structures against ontology constraints.
When should I use Ontology Validator?
Ontology Validator fits situations like: checking if CMSO annotations are correct; verifying that required properties are present; validating that object property relationships have consistent domain and range.
How do I install Ontology Validator in Claude Code?
Run `npx skills add FreedomIntelligence/OpenClaw-Medical-Skills --skill ontology-validator -a claude-code`. Or copy the skill folder (skills/ontology-validator in FreedomIntelligence/OpenClaw-Medical-Skills) into .claude/skills/ontology-validator in your project.

Can I use Ontology Validator in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add FreedomIntelligence/OpenClaw-Medical-Skills --skill ontology-validator -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ontology-validator, .gemini/skills/ontology-validator, .github/skills/ontology-validator and .opencode/skills/ontology-validator in your project.
What does Ontology Validator need to run?
Going by SKILL.md and its folder, Ontology Validator needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Bash.
Does Ontology Validator access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Ontology Validator safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Ontology Validator use?
No licence was found for Ontology Validator or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Ontology Validator use?
About 1.4k tokens (SKILL.md is roughly 5.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.1k tokens, read only when the agent opens those files.
