OSNK Trainer

Pelatih OSNK - Bank soal OSK/OSNK/SNK/Bebras (2006-2025) dengan latihan cerdas, speed run, performance tracking, dan mentoring lengkap.

Security Scan

The skill's description and bundled question files line up with an offline trainer, but the runtime shell script (run.sh) that the skill depends on was not provided for code review here and the SKILL.md / SECURITY.md assert optional network access to raw.githubusercontent.com — this combination warrants caution before installing.

Purpose & Capability

The name/description (OSNK trainer) match the packaged content: many local .md question banks, a simple bash runtime, and JSON state files. There are no declared env vars, binaries, or unrelated credentials requested, which is proportional to an offline quiz trainer.

Instruction Scope

SKILL.md describes only local operations (reading .md files, writing JSON into memory/) which is consistent — but it also documents an optional GitHub fallback (raw.githubusercontent.com) used when local files are missing. The provided package includes a SECURITY.md that describes run.sh behavior, but the actual run.sh source was not included in the review text here (only its presence/size is listed). Because the runtime behavior (parsing commands, fetching fallbacks) is implemented by run.sh, not seeing its contents prevents verification that it truly never executes arbitrary code, never uses eval, and only performs safe GET requests.

Install Mechanism

There is no install spec (instruction-only skill plus an included run.sh). That is low-risk compared to remote installers. No archives or third-party package installs are declared. However, the included executable script (run.sh) would be executed at runtime — its contents should be reviewed before running.

Credentials

The skill declares no required env vars or credentials and stores data under $OPENCLAW_WORKSPACE/memory or ./memory — this is proportional. Note: SKILL.md/SECURITY.md reference $OPENCLAW_WORKSPACE and an optional outbound HTTPS fallback to raw.githubusercontent.com/jrrqd/osnk-question-bank; network access is reasonable for a fallback but it is an external endpoint and should be trusted/verified before allowing the skill to fetch from it.

Persistence & Privilege

always is false and the skill stores only JSON under the workspace memory directory. It does not request system-wide privileges. SECURITY.md mentions no sudo or system modifications. There is a minor oddity: SECURITY.md points to a local path under a developer's home and an npm-global path which suggests typical dev install locations, but not elevated privileges.

What to consider before installing

This package appears to be a legitimate offline OSNK/Bébras question trainer with local markdown banks and local JSON state — but before installing or enabling autonomous invocation you should: 1) Inspect run.sh yourself (open the file) to confirm it contains only safe parsing, file reads/writes, and at most harmless HTTPS GETs to the documented GitHub raw URL; look specifically for no eval/exec of downloaded content, no use of curl/wget|--output to execute archives, and no exfiltration logic. 2) If you cannot review the script, run the skill in an isolated sandbox or VM and monitor network traffic and filesystem writes. 3) If you allow the GitHub fallback, verify the exact repository URL (raw.githubusercontent.com/jrrqd/osnk-question-bank) and ensure you trust that upstream content; consider blocking network access if you want fully local-only operation. 4) Check that writing to $OPENCLAW_WORKSPACE/memory (or ./memory) fits your privacy requirements and that you are comfortable storing practice data locally. 5) Because source/homepage are unknown, prefer manual review and sandboxing; if you need higher assurance, ask the author for the run.sh source (or for a signed release) and verify it matches the packaged script.

Penyimpanan Data

Semua data pengguna disimpan secara lokal di workspace Anda:

• Progres: memory/osnk-progress.json
• Statistik: memory/osnk-stats.json
• Konfigurasi: memory/osnk-config.json

Tidak ada informasi pribadi yang dikumpulkan. Semua data bersifat anonim.

🔒 Keamanan & Transparansi (April 2026)

Skill ini mencakup dokumen keamanan lengkap SECURITY.md yang menjelaskan fungsi shell script run.sh:

Apa yang run.sh lakukan:

• Command routing bash sederhana untuk parsing perintah natural language
• Mengambil soal dari file markdown lokal atau GitHub fallback (opsional)
• Menyimpan statistik performa ke JSON di workspace user

Yang TIDAK dilakukan:

• ❌ Tidak mengeksekusi kode arbitrer
• ❌ Tidak mendownload executable pihak ketiga
• ❌ Tidak mengirim data keluar tanpa izin explisit
• ❌ Tidak memodifikasi sistem files diluar workspace
