hello_world_system

hello_world_system is a skill for Claude Code, Codex from asepsafrudin/multiple-mcp-server-by-kimi. It costs 28 tokens per session (311 once invoked), scanned A, original, MIT.

A small readiness check that returns a greeting to test an smolagents executor and an E2B sandbox. smolagents is a framework for running AI agents, and E2B provides isolated environments for running code.

In plain words
What is it for?
Use it when verifying that a smolagents setup can start and communicate with its sandbox.
Why use it?
It gives a simple way to check whether both the agent executor and its code sandbox are available.

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 A, and why

hello_world_system scanned grade A with 0 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 18d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Keterampilan: Hello World & System Check

Keterampilan (Skill) ini digunakan oleh agen (seperti smolagents, Cursor, atau Claude) untuk memverifikasi bahwa lingkungan sandbox / python eksekutor sudah stabil dan mampu memproses operasi matematis dasar.

Mekanisme

  1. Eksekutor koding (misal CodeAgent di smolagents) diminta membaca struktur file ini.
  2. Agen menulis baris kode Python yang mampu mengeksekusi sapaan dan perhitungan.

Contoh Eksekusi Kode Python

Saat agen dipanggil, Anda dapat menggunakan potongan panduan di bawah ini untuk menghasilkan operasi:

def check_environment():
    import sys
    print("Halo Dunia! Smolagents Sandbox Test.")
    print(f"Versi Python: {sys.version}")
    # Uji kalkulasi otonom
    return 19 * 21

print(f"Kalkulasi agen: {check_environment()}")

Parameter Kesuksesan (Post-Condition)

  • Agen berhasil mendapatkan exit-code 0 dari eksekusi python.
  • Output standar (stdout) mencetak teks "Halo Dunia!".
  • Setelah ini tereksekusi, workflow dapat diteruskan kembali ke Lapisan 1 (MAF Orchestrator).

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.
