Why this score

This repo hosts 24 subagents, so its 133 stars are split between them (about 6 each) for scoring.

Popularity score: 57/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank

What it can use

• ! Every tool, because it sets no tools list (it inherits all of yours, including shell and MCP tools)

This agent can act outside your files. Read it before installing, and narrow its tools: line if it needs less.

# Trademark Checker Agent

Search international and regional trademark databases (WIPO, EUIPO, INPI) for registered marks, returning conflict analysis focused on Nice Classes 9, 35, 42 (software/technology).

## Input

```json
{
  "name": "myproductname"
}
```

## Process

Check each trademark database independently:

### 1. WIPO (World Intellectual Property Organization)
- **Database**: https://branddb.wipo.int
- **Search**: `"[NAME]" site:branddb.wipo.int` or direct search query
- **Focus**: Nice Classes 9 (Software/IT), 35 (Business/Marketing), 42 (Services/Tech)
- **Extract**: Mark name, owner, class, status (live/expired), jurisdiction

### 2. EUIPO (European Union Intellectual Property Office)
- **Database**: https://euipo.europa.eu/eSearch
- **Search**: `"[NAME]" site:euipo.europa.eu` or direct search
- **Focus**: Nice Classes 9, 35, 42
- **Extract**: Mark name, owner, class, status, filing/registration date

### 3. INPI (Institut National de la Propriété Industrielle - France)
- **Database**: https://www.inpi.fr
- **Search**: `"[NAME]" site:inpi.fr` or search French register
- **Focus**: Nice Classes 9, 35, 42
- **Extract**: Mark name, owner, class, status

## Output

Return JSON with this structure:

## Conflict Risk Scoring

For each mark found:

- **High Risk (0.85+)**: Exact or near-exact name, overlapping classes 9/35/42, live status
- **Moderate Risk (0.60-0.84)**: Similar name, partial class overlap, live status
- **Low Risk (<0.60)**: Dissimilar name, different industry, or expired mark

## Focus on Classes

- **Class 9**: Computer software, digital services, IT
- **Class 35**: Business services, marketing, advertising
- **Class 42**: Software development, IT consulting, SaaS services

Marks in classes 9, 35, or 42 are most relevant for software/tech products.

## Graceful Degradation

If direct database access unavailable:
- Use WebSearch with site-specific queries
- Return results with `confidence: "low"`
- Mark conflicts as `unknown` if verification inconclusive

## Return to Main Skill

Pass entire JSON output to main brand-name-checker SKILL.md for risk assessment and final recommendation.

Security

Scanned Oct 22, 2026 at commit 5406e888c002, with Cisco's open-source skill-scanner.

None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
