openfda-database

openfda-database is a skill for Claude Code, Codex from google-deepmind/science-skills. It costs 81 tokens per session (2,282 once invoked), scanned A, original, Apache-2.0.

A guide for querying openFDA, a United States Food and Drug Administration database and API covering medicines, devices, foods, cosmetics, tobacco, and related records.

In plain words
What is it for?
Searching adverse events, recalls, drug labels, approvals, shortages, medical-device clearances, product identifiers, and other FDA records.
Why use it?
It provides the required setup and safe query process for retrieving FDA regulatory and safety information without directly accessing the database.

About the project

Science Skills is a collection of add-ons that give AI agents structured instructions, scripts, and references for scientific research, including genomics, structural biology, cheminformatics, and literature search. Researchers use it to guide agents through specialized scientific tasks with information from databases and tools such as AlphaGenome, AFDB, and UniProt. The catalogue entries are individual skills from this collection.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

openfda-database scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/openfda_query.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

openFDA Search and Query

Prerequisites

  1. uv: Read the uv skill and follow its Setup instructions to ensure uv is installed and on PATH.
  2. User Notification: If .licenses/openfda_database_LICENSE.txt does not already exist in the workspace root directory then (1) prominently notify the user to check the terms at https://open.fda.gov/apis/ and https://open.fda.gov/license, then (2) create the file recording the notification text and timestamp.
  3. .env file: Make sure the .env file exists in your home directory. Create one if it does not exist.
  4. FDA_API_KEY (optional but recommended): Raises the daily request limit from 1,000 to 120,000. The skill works without it, but an agent can easily exhaust the keyless limit in a single session. You can register for a free key at https://open.fda.gov/apis/authentication/. You MUST use the safe credentials protocol in the credentials skill to check for and request this key if this skill looks relevant to the user's request.

Core Rules

  • Use the Wrapper: ALWAYS execute the provided helper scripts to query the database rather than accessing the database directly. The scripts automatically enforce the required rate limit gracefully.

  • Rate Limiting: Respect openFDA rate limits. Without API key: 240 requests/min, 1,000 requests/day per IP. With API key: 240 requests/min, 120,000 requests/day per key. Always set an API key before running multi-query workflows.

Warning: An automated agent can easily exhaust the 1,000-request daily limit in a single research session. Always set an API key before running multi-query workflows.

You MUST use the safe credentials protocol in the credentials skill to help the user add FDA_API_KEY to their .env file if this skill looks relevant to the user's request. The script will emit a warning to stderr if no API key is detected.

  • Always Use --output: All subcommands require --output <file> to write results to a file. This prevents large output becoming overwhelming. Use jq or code to read the output file.

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
