At a glance

Query the FDA Adverse Event Reporting System (FAERS) via openFDA API.

  • The user asks about adverse drug reactions
  • SKILL.md covers API, Usage and Notes
  • Runs Python scripts from its folder; reaches api.fda.gov
  • Drug safety signals

What it does

Faers Query is an agent skill from QSong-github/DrugClaw. Query the FDA Adverse Event Reporting System (FAERS) via openFDA API. Use whenever the user asks about adverse drug reactions, side effects, drug safety signals, or wants to look up reported adverse events for one or more drug names.

Its SKILL.md is about 350 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`).

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 about adverse drug reactions
  • Drug safety signals
  • Wants to look up reported adverse events for one
  • More drug names

Example prompts

  • “/faers-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:

    • api.fda.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

Faers Query loads about 347 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 119 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~347

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 119 words (~347 tokens).

“Query adverse event reports from FDA's FAERS database. No API key required.”
