In plain words
What is it for?
Use it to audit a codebase, check dependencies, find typosquatting or suspicious patterns, and produce a security report.
Why use it?
It helps uncover threats hidden in packages or source code before they affect your project.

Which agent this was written for is unclear — built for roo code. Also seen: positional $N argument; mentions Claude Code; built for roo code.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 /tmp/sentinel_scanner.py --path <PROJECT_DIR> --output /tmp/sentinel_report.json.

Good fit Use it to audit a codebase, check dependencies, find typosquatting or suspicious patterns, and produce a security report.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 B, and why

supply-chain-sentinel scanned grade B with 3 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 9d 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.

Reaches for credential filesmediumPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

(r'open\s*\(\s*["\'][^"\']*(?:\.aws|credentials|\.netrc)["\']', "CRITICAL", "acesso a arquivo de credenciais"),

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Supply Chain Sentinel

Scanner portátil de segurança para detectar ataques de supply chain, dependências maliciosas, injeção de prompt, código obfuscado e padrões suspeitos em projetos de software.

Fluxo de Execução

  1. Leia este arquivo completo antes de começar
  2. Execute o scanner Python via scripts/scanner.py
  3. Complemente com análise manual dos achados de alta severidade
  4. Gere o relatório final em Markdown

Passo 1 — Localizar o Projeto

Se o usuário não especificou o path:

# Tenta caminhos comuns
ls /mnt/user-data/uploads/ 2>/dev/null || true
ls ~/project/ 2>/dev/null || true
pwd

Pergunte ao usuário se não encontrar. O scanner aceita qualquer diretório raiz.


Passo 2 — Executar o Scanner

Copie o script para um local gravável e execute:

cp /mnt/skills/*/supply-chain-sentinel/scripts/scanner.py /tmp/sentinel_scanner.py \
  || cp "$(dirname "$0")/scripts/scanner.py" /tmp/sentinel_scanner.py

python3 /tmp/sentinel_scanner.py --path <PROJECT_DIR> --output /tmp/sentinel_report.json

Se o script não estiver acessível via path relativo, escreva-o em disco usando o conteúdo da seção ## Scanner Script abaixo, salve em /tmp/sentinel_scanner.py e execute normalmente.


Passo 3 — Análise Manual Complementar

Após o scanner, faça buscas direcionadas nos achados críticos:

3a. Verificar setup.py / pyproject.toml suspeitos

# Chamadas de rede no setup
grep -rn "urllib\|requests\|socket\|http" <PROJECT_DIR>/setup.py \
  <PROJECT_DIR>/pyproject.toml 2>/dev/null

# Exec/eval no install
grep -rn "exec\|eval\|compile\|__import__" <PROJECT_DIR>/setup.py 2>/dev/null

3b. Strings Base64 / Ofuscadas

grep -rEn "base64\.(b64decode|decodebytes)|\\\\x[0-9a-f]{2}|eval\(.*decode" \
  <PROJECT_DIR> --include="*.py" --include="*.js" --include="*.ts" 2>/dev/null | head -50

3c. Prompt Injection em arquivos de config/prompt

grep -rniP "(ignore previous|disregard|you are now|forget your|override instructions|\
act as if|new system prompt|jailbreak|\\[INST\\]|<\|system\|>)" \
  <PROJECT_DIR> --include="*.txt" --include="*.md" --include="*.json" \
  --include="*.yaml" --include="*.yml" --include="*.toml" 2>/dev/null

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.

supply-chain-sentinel is a skill published in the GitHub repository Bilal140202/the-lord-of-the-skills (4 stars, last pushed 6d ago), licensed MIT. It adds 159 tokens to every session and 7,678 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it B with 3 findings (reaches for credential files, makes network calls, runs shell commands). It is 100% identical to supply-chain-sentinel, differing in 0 lines, and is treated as a copy.
