visualizer-launcher

visualizer-launcher is an agent for Claude Code from nainsharma01/claude-code-visualizer. It costs 50 tokens per session (1,428 once invoked), scanned D, original, MIT.

A launcher for a web-based graph showing relationships between coding agents and their skills. It scans a project, creates graph data, starts the required servers, and opens the visualisation.

In plain words
What is it for?
Use it to generate and view an agent-skill relationship graph when exploring or explaining a project's structure.
Why use it?
It makes a large agent-and-skill setup easier to inspect than a collection of folders and configuration files. The generated graph can reveal how the parts of the project connect.

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 D, and why

visualizer-launcher scanned grade D with 2 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 4d ago.

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.

Visualizer Launcher - 에이전트 시각화 실행

agent-skill-visualizer를 자동으로 실행하여 에이전트와 스킬 관계를 웹 브라우저에서 시각화합니다.

역할

  1. 그래프 데이터 생성: 프로젝트 스캔하여 JSON 생성
  2. SSE 서버 시작: 실시간 스트리밍 백엔드 (port 3001)
  3. 웹앱 실행: React 개발 서버 (port 5174)
  4. 브라우저 열기: 자동으로 시각화 페이지 오픈

실행 워크플로우

Phase 1: 환경 확인

먼저 필요한 파일과 의존성 확인:

# 1. 스킬 디렉토리 확인
ls -la .claude/skills/agent-skill-visualizer/

# 2. Python 가상환경 확인 (SSE 서버용)
test -f .venv/bin/python && echo "✓ Python venv exists" || echo "✗ venv not found"

# 3. Node modules 확인 (웹앱용)
test -d .claude/skills/agent-skill-visualizer/webapp/node_modules && echo "✓ npm dependencies installed" || echo "✗ Run npm install"

Phase 2: 의존성 설치 (필요시)

Node modules가 없으면 설치:

cd .claude/skills/agent-skill-visualizer/webapp && npm install

Phase 3: 그래프 데이터 생성

프로젝트를 스캔하여 최신 데이터 생성:

python .claude/skills/agent-skill-visualizer/scripts/scan_agents_skills.py . \
  --output .claude/skills/agent-skill-visualizer/webapp/public/data/graph-data.json

결과 확인:

cat .claude/skills/agent-skill-visualizer/webapp/public/data/graph-data.json | jq '.metadata'

Phase 4: 서버 시작

중요: 두 서버를 백그라운드로 실행해야 합니다.

4-1. SSE 서버 시작 (백그라운드)
cd .claude/skills/agent-skill-visualizer/scripts && \
python3 stream_server.py > /tmp/sse_server.log 2>&1 &
echo $! > /tmp/sse_server.pid

확인:

# 프로세스 확인
ps -p $(cat /tmp/sse_server.pid) > /dev/null && echo "✓ SSE server running" || echo "✗ SSE server not running"

# 로그 확인
tail -5 /tmp/sse_server.log
4-2. 웹앱 개발 서버 시작 (백그라운드)
cd .claude/skills/agent-skill-visualizer/webapp && \
npm run dev > /tmp/vite_server.log 2>&1 &
echo $! > /tmp/vite_server.pid

확인:

# 프로세스 확인
ps -p $(cat /tmp/vite_server.pid) > /dev/null && echo "✓ Vite server running" || echo "✓ Vite server running"

# 포트 확인
lsof -i :5174 | grep LISTEN && echo "✓ Port 5174 listening"

Phase 5: 브라우저 열기

서버가 준비되면 자동으로 브라우저 오픈:

# 2초 대기 (서버 초기화 시간)
sleep 2

# macOS에서 기본 브라우저로 열기
open http://localhost:5174

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.

visualizer-launcher is an agent published in the GitHub repository nainsharma01/claude-code-visualizer (5 stars, last pushed yesterday), licensed MIT. It adds 50 tokens to every session and 1,428 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it D with 2 findings (enumerates other installed skills, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
