Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# ATC/DDD Query Skill Look up ATC classification and DDD data for drugs. Auto-detects entity type: | Input Pattern | Detected As | Query Path | |---|---|---| | `N02BA` `A10BA02` `C09XX01` | ATC code | local DDD lookup + RxNav member drugs | | `aspirin` `metformin` | drug name | RxNav ATC classification + local DDD match | ATC code regex: `^[A-Z]\d{2}([A-Z]{1,2}\d{0,2})?$` ## API | Function | Input | Returns | |---|---|---| | `load_local(path)` | Excel path | `list[dict]` — cached ATC/DDD records | | `search(entity)` | single string | `dict` with `entity`, `entity_type`, `local_hits`, `api_hits` | | `search_batch(entities)` | list of strings | `dict[str, dict]` — keyed by entity | | `summarize(result)` | search result dict | compact LLM-readable text | | `to_json(result)` | search result dict | JSON string | All functions accept `use_api=True|False` to toggle RxNav queries (default: on). ## Usage See `if __name__ == "__main__"` block in `27_ATC_DDD.py` for runnable examples: ```python from importlib import import_module atc = import_module("27_ATC_DDD") # Drug name → ATC classes r = atc.search("aspirin") print(atc.summarize(r)) # ATC code → member drugs + DDD r = atc.search("N02BA")

What does the 27_ATC_DDD skill do?
Query the WHO ATC/DDD Classification System. Use whenever the user asks about ATC codes, drug classification hierarchy, Defined Daily Doses (DDD), or wants to look up drugs by ATC class or find the ATC code for a drug name.
How do I install it?
Run `npx skills add BioTender-max/awesome-bio-agent-skills --skill atc --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From BioTender-max/awesome-bio-agent-skills, a repository with 135 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
