## What it does

The skill evaluates protein and gene targets across four dimensions: human genetic support from GWAS and ClinVar, druggability via Pharos TDL and ChEMBL bioactivity, tissue-specific safety, and current competition. It handles disambiguation first by resolving gene symbols into UniProt accessions or Ensembl identifiers.

Research follows a report-first structure. The agent initializes the target dossier file before querying, grades all collected evidence from T1 to T4, and records negative findings instead of leaving empty sections. Calls to underlying biological APIs are automatically translated into English to avoid query failures against external databases.

Parameter verification is strictly enforced before running tools, because parameter signatures differ between data sources. Reactome expects `uniprot_id`, while Ensembl uses `id`. This check prevents execution errors midway through data gathering. For simple sequence downloads or standalone chemical lookups, this workflow is excessive.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mims-harvard/ToolUniverse tooluniverse-target-research
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse-target-research -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mims-harvard/ToolUniverse --path skills/tooluniverse-target-research
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse-target-research -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- assess druggability and tractability for a protein or gene target
- verify human genetic evidence linking a target to a disease
- retrieve tissue expression data across GTEx and Human Protein Atlas
- identify active chemical matter and binding affinity in ChEMBL

## Example prompts
- Run a target validation report for EGFR in lung cancer
- Check the safety profile and tissue expression of KRAS using GTEx
- Evaluate genetic evidence and druggability for PCSK9

# Comprehensive Target Intelligence Gatherer

Gather complete target intelligence by exploring 9 parallel research paths. Supports targets identified by gene symbol, UniProt accession, Ensembl ID, or gene name.

**KEY PRINCIPLES**:
1. **Report-first approach** - Create report file FIRST, then populate progressively
2. **Tool parameter verification** - Verify params via `get_tool_info` before calling unfamiliar tools
3. **Evidence grading** - Grade all claims by evidence strength (T1-T4)
4. **Citation requirements** - Every fact must have inline source attribution
5. **Mandatory completeness** - All sections must exist with data minimums or explicit "No data" notes
6. **Disambiguation first** - Resolve all identifiers before research
7. **Negative results documented** - "No drugs found" is data; empty sections are failures
8. **Collision-aware literature search** - Detect and filter naming collisions
9. **English-first queries** - Always use English terms in tool calls, even if the user writes in another language. Translate gene names, disease names, and search terms to English. Only try original-language terms as a fallback if English returns no results. Respond in the user's language

## LOOK UP, DON'T GUESS

When asked about a specific protein or gene target, look it up in UniProt/Ensembl/OpenTargets BEFORE reasoning about it. Verify the gene name, function, and disease associations from databases. When you're not sure about a fact, your first instinct should be to SEARCH for it using tools, not to reason harder from memory.

## When to Use This Skill

Apply when users:
- Ask about a drug target, protein, or gene
- Need target validation or assessment
- Request druggability analysis
- Want comprehensive target profiling
- Ask "what do we know about [target]?"
- Need target-disease associations
- Request safety profile for a target
```
