## What it does

This skill queries 28 openFDA API endpoints and writes responses to JSON files. It covers FDA datasets for drugs, devices, food, tobacco, cosmetics, veterinary products, substances and transparency, including recalls, approvals, shortages and 510(k) clearances.

All operations go through `uv run scripts/openfda_query.py`. Its `search`, `count` and `download` subcommands retrieve records, aggregate a field, or fetch multiple pages; every call requires `--output <file>` so large responses are stored outside the agent context.

You need `uv`, a `.env` file in the home directory, and an openFDA terms notice in `.licenses/openfda_database_LICENSE.txt`. `FDA_API_KEY` is optional, but the keyless allowance is 1,000 daily requests rather than 120,000 per key. For multi-query work, an API key is effectively required because an agent can exhaust the smaller limit in one session. Set the key before a multi-query run.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill openfda-database -a claude-code
```
```bash
npx skills add google-deepmind/science-skills --skill openfda_database -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/openfda_database/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/openfda_database/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill openfda_database -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/openfda_database/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill openfda_database -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/openfda_database/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install google-deepmind/science-skills openfda_database
```

2. **Manually: put the files in place**
- File: `.github/skills/openfda_database/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill openfda_database -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/google-deepmind/science-skills --path skills/openfda_database
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/openfda_database/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add google-deepmind/science-skills --skill openfda_database -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- search adverse event reports for a drug
- count recurring reactions in matching records
- download several result pages into JSON
- look up a product by NDC
- find FDA labels or recall records

## Example prompts
- Search adverse events for aspirin and save the JSON to `/tmp/fda_results.json`.
- Count reactions for aspirin in the `drug` `event` endpoint and write the result to `/tmp/aspirin_reactions.json`.
- Look up NDC `51285-092` and save the response to `/tmp/ndc.json`.

  Query, search, and download data from the openFDA API for drugs, devices,

# 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.
