## What it does

The skill runs in phases. It resolves the drug to a ChEMBL and DrugBank ID, pulls the most frequent adverse events from FAERS, then computes PRR, ROR and IC with 95% confidence intervals for each one. From there it mines FDA label sections, checks mechanism of action through OpenTargets and DrugBank, compares the drug against others in its class, and searches PubMed for case reports and safety studies. The output is a Safety Signal Score from 0 to 100 plus evidence grading from T1 to T4.

Computation is the point here. Statistics, scoring and enrichment run as Python code through Bash, using pandas, scipy, statsmodels and matplotlib, so the agent executes the analysis instead of describing it. Causality follows the Naranjo algorithm: prior reports, timing, dechallenge, rechallenge, alternative causes, dose-response. The signal threshold is fixed — PRR of at least 2.0, at least 3 cases, lower confidence bound above 1.0.

You need the ToolUniverse tools that fetch FAERS, FDA labels, OpenTargets, DrugBank and PharmGKB data. Without them the data phases have nothing to work with and you are left with text-only reasoning. The directory also ships `PHASE_DETAILS.md`, `REPORT_TEMPLATE.md`, `TOOL_REFERENCE.md` and `QUICK_START.md` with tool call examples and a report template.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse-adverse-event-detection -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse-adverse-event-detection -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse-adverse-event-detection -a cursor
```

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

npx skills add mims-harvard/ToolUniverse --skill tooluniverse-adverse-event-detection -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mims-harvard/ToolUniverse/tree/HEAD/skills/tooluniverse-adverse-event-detection/SKILL.md

## When to use it
- surface adverse events that clinical trials missed
- compute PRR, ROR and IC for one drug with confidence intervals
- compare the safety profile of two drugs in the same class
- break down serious outcomes: deaths, hospitalizations, life-threatening events
- grade causality with the Naranjo algorithm for a regulatory submission

## Example prompts
- What are the FAERS safety signals for metformin?
- Compare the adverse event profile of two statins
- Is this drug associated with rhabdomyolysis? Calculate PRR and ROR

description: Detect and analyze adverse drug event signals using FDA FAERS reports, drug labels, and disproportionality statistics (PRR, ROR, IC). Generates quantitative safety signal scores (0-100) with evidence grading. Use for post-market surveillance, pharmacovigilance, drug safety assessment, regulatory submissions, and detecting rare AE signals not visible in clinical trials.

## COMPUTE, DON'T DESCRIBE
When analysis requires computation (statistics, data processing, scoring, enrichment), write and run Python code via Bash. Don't describe what you would do — execute it and report actual results. Use ToolUniverse tools to retrieve data, then Python (pandas, scipy, statsmodels, matplotlib) to analyze it.

# Adverse Drug Event Signal Detection & Analysis

Automated pipeline for detecting, quantifying, and contextualizing adverse drug event signals using FAERS disproportionality analysis, FDA label mining, mechanism-based prediction, and literature evidence. Produces a quantitative Safety Signal Score (0-100) for regulatory and clinical decision-making.

**KEY PRINCIPLES**:
1. **Signal quantification first** - Every adverse event must have PRR/ROR/IC with confidence intervals
2. **Serious events priority** - Deaths, hospitalizations, life-threatening events always analyzed first
3. **Multi-source triangulation** - FAERS + FDA labels + OpenTargets + DrugBank + literature
4. **Context-aware assessment** - Distinguish drug-specific vs class-wide vs confounding signals
5. **Report-first approach** - Create report file FIRST, update progressively
6. **Evidence grading mandatory** - T1 (regulatory/boxed warning) through T4 (computational)
7. **English-first queries** - Always use English drug names in tool calls, respond in user's language

**REASONING STRATEGY — Start Here**:
