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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00159 | $0.07678 |
| Opus 5.5 | $0.00064 | $0.03071 |
| Sonnet 5.5 | $0.00032 | $0.01536 |
| Haiku 4.5 | $0.00016 | $0.00768 |
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 1mo 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
grep -rn "urllib\|requests\|socket\|http" <PROJECT_DIR>/setup.py \ Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.

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
- Leia este arquivo completo antes de começar
- Execute o scanner Python via
scripts/scanner.py - Complemente com análise manual dos achados de alta severidade
- 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 (6 stars, last pushed 1mo ago), licensed MIT. It adds 159 tokens to every session and 7,678 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it B with 3 findings (reaches for credential files, makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

Use when a tool-calling agent does not call a tool, sends wrong arguments, loops without stopping, or needs a function schema. Guides a four-branch diagnosis and five-step schema repair. Do not use for framework-specific, MCP-server, or production-observability questions.
ainb-fleet:daemons
Runtime-health view of the four fleet daemons — phone bridge, notifyd, ATC, and the fleet auto-continue daemon — in one table. Each row reports state (running / stopped / unknown), pid, uptime, last activity, error count, and a HEALTH reason that distinguishes a clean stop from a crash (stale heartbeat) or a…
ainb-fleet:atc
ATC (Air Traffic Control) — the single operator-visible fleet supervisor, in exactly one mode: lite (no LLM: deterministic scan, known-transient retry policy, safety caps, evidence) or full (the persistent orchestrating brain). Full mode is a plain ainb session (Claude or Codex) running a generated policy, woken on a…
ainb-fleet:fleet-needs
Workflow-backed Jarvis control panel. Runs the deterministic hangar workflow with verb=needs (discover → enrich → prioritize), renders the Jarvis HUD from its render-ready cards, fires AskUserQuestion per blocked session, and routes each answer back via tmux send-keys (broker fallback only). Requires the workflow gate…
