52_NDF_RT

Query NDF-RT (National Drug File Reference Terminology) via the NCI EVS REST API. Use when looking up drug mechanisms of action, physiological effects, pharmacologic classes, chemical structures, or drug–disease relationships (may_treat / may_prevent) in NDF-RT. Accepts drug names or NDF-RT codes.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
4 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by QSong-github on GitHub. Read the source before you install it.

Installation

Install the 52 NDF RT AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/QSong-github/DrugClaw/tree/main/skills/drug_ontology/ndfrt
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/QSong-github/DrugClaw.git /tmp/DrugClaw
mkdir -p .claude/skills
cp -r /tmp/DrugClaw/skills/drug_ontology/ndfrt .claude/skills/52_NDF_RT

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable 52 NDF RT in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads 52 NDF RT on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so 52 NDF RT is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

NDF-RT Query Skill

Search NDF-RT concepts by drug name or NDF-RT code via the NCI EVS REST API. Auto-detects entity type by pattern:

Input Pattern	Detected As	Lookup Logic
`N0000145918`	NDF-RT code (`N` + 10 digits)	direct concept GET
anything else	free text	full-text search endpoint

API

Function	Input	Returns
`search(entity, limit)`	single entity string	`dict` with `entity`, `type`, `results`
`search_batch(entities, limit)`	list of entity strings	`dict[str, dict]`
`summarize(result, entity)`	search result dict + label	compact multi-line text
`to_json(result)`	search result dict	`list[dict]`

Result dict structure

Each item in results contains:

Key	Description
`code`	NDF-RT concept code
`name`	Preferred concept name
`kind`	Concept kind (e.g. `DRUG_KIND`, `DISEASE_KIND`)
`properties`	flat `{type: value}` property dict
`roles`	list of `{type, relatedCode, relatedName}` role relationships
`parents`	list of `{code, name}` ISA parent concepts
`synonyms`	deduplicated list of synonym strings

Key NDF-RT relationship types (roles)

Role	Meaning
`has_MoA`	mechanism of action
`has_PE`	physiological effect
`has_EPC`	established pharmacologic class
`may_treat`	indicated disease/condition
`may_prevent`	preventable disease/condition
`CI_with`	contraindicated with
`has_Chemical_Structure`	chemical structure classification

Usage

See if __name__ == "__main__" block in 52_NDF_RT.py for runnable examples covering: drug name search, code lookup, batch search, JSON output, and root concept listing.

Frequently asked questions

What does the 52 NDF RT AI skill do?

Why use 52 NDF RT on TypingMind?

Because you install it once and use it with any model. 52 NDF RT is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install 52 NDF RT in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/QSong-github/DrugClaw/tree/main/skills/drug_ontology/ndfrt. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use 52 NDF RT?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with 52 NDF RT?

As many as you like. As long as a model supports skills, you can use 52 NDF RT with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the 52 NDF RT AI skill free?

It is published on GitHub by QSong-github. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
