Query the RxNorm drug naming and normalization API. An agent skill from QSong-github/DrugClaw.

  • SKILL.md covers Capabilities, Quick Start, query() Output Schema and Notes
  • Runs Python scripts from its folder; reaches rxnav.nlm.nih.gov
  • Normalize a drug name

What it does

Rxnorm Query is an agent skill from QSong-github/DrugClaw. Query the RxNorm drug naming and normalization API. Use whenever the user asks to look up an RxCUI, normalize a drug name, find drug interactions, retrieve brand/trade names, or resolve any clinical drug name via RxNorm. Supports single drug or batch queries. Trigger on mentions of RxNorm, RxCUI, drug normalization, drug interaction lookup, or brand-name resolution.

Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files (for example `README.md`, `__init__.py` and `example.py`).

It sits in Databases, covering Database schema design. The repository describes itself as: 🦀 Agentic RAG for drug intelligence · 57 skills · 15 task categories · DTI · ADR · DDI · PGx · Repurposing · Powered by LangGraph.

When your agent uses it

  • The user asks to look up an RxCUI
  • Normalize a drug name
  • Find drug interactions
  • Retrieve brand/trade names

Example prompts

  • “/rxnorm-query”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit bc7b93e. 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

    Ships script files (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • rxnav.nlm.nih.gov

    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

Rxnorm Query loads about 476 tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 113 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~476

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 113 words (~476 tokens).

“Look up clinical drug information via the RxNorm REST API (no API key required).”
