qsnctf-practice-dynamic

获取青少年CTF练习场的排行榜和解题动态。Invoke when user wants to check QSNCTF leaderboard or recent solve activities.

Security Scan

The skill's code and instructions match its description: it fetches leaderboard and recent-solve data from qsnctf.com, requests no credentials, and contains no unexpected behavior.

Purpose & Capability

Name/description promise (QSNCTF leaderboard and dynamics) aligns with included script and SKILL.md. The script calls the stated qsnctf.com API endpoints and formats results; nothing requested that would be unrelated (no cloud creds, no unrelated services).

Instruction Scope

Runtime instructions are limited and concrete: run the provided Python script with action arguments. The SKILL.md and script only perform HTTP GETs to the documented endpoints and print formatted results. The instructions do not read local secrets, system files, or send data to third parties beyond qsnctf.com.

Install Mechanism

No install spec included (instruction-only plus a simple Python script). Dependencies are minimal (requests) and installation via pip is documented. No downloads from untrusted URLs or archive extraction.

Credentials

The skill requires no environment variables, no credentials, and no config paths. The script uses only public HTTP GET requests; there is no disproportionate secret access.

Persistence & Privilege

Skill does not request always:true and does not modify system or other skills. It is user-invocable and can be invoked autonomously (platform default) but its functionality is limited to on-demand API queries.

Assessment

This skill appears to be what it claims: a small Python tool that queries public QSNCTF APIs and prints leaderboard / solve activity. Before installing/using: (1) note it will perform network requests to https://www.qsnctf.com (no credentials required), (2) pip-installing requests gives the script network ability—run in an environment you control if you’re cautious, and (3) you can review the included scripts/qsnctf_stats.py (already provided) — it contains no hidden endpoints or secret exfiltration. If you don't trust the publisher, run it in a sandbox or inspect/execute the script manually rather than granting it broad automated privileges.
