Security Scan

The skill is mostly a coherent CET‑6 spaced‑repetition vocabulary assistant, but its runtime instructions include system-level scheduling and root-path scripts (and a copy/paste reference to CET‑4) that are disproportionate to its declared requirements and could modify crontab or send messages without clearly declared permissions.

Purpose & Capability

The name/description match the content: vocabulary lists, spaced repetition algorithm, CSV-based user/schedule state. However, parts of the included docs reference setting system crontab entries and a reminder script under /root/.openclaw (and even mention CET‑4), which is beyond what a pure in‑agent learning skill strictly needs and looks like copy/paste or scope creep.

Instruction Scope

SKILL.md and references instruct the agent to read/write local CSV files (expected) but also to check and modify system crontab, place/execute reminder scripts under /root/.openclaw/scripts, and invoke an OpenClaw CLI to send messages to a <user_id>. Those actions touch system scheduling and messaging functionality outside the simple vocabulary task and are not fully justified or constrained in the docs.

Install Mechanism

This is an instruction‑only skill with no install spec and no code to fetch — low installation risk. Nothing will be written to disk by an installer, but the runtime instructions themselves propose writing scripts and crontab entries.

Credentials

The skill declares no required env vars or config paths, yet the docs reference account names, target user IDs, and CLI usage (/root/.local/share/pnpm/openclaw message send --account default --target <user_id>) and root filesystem paths. Those credentials/configurations are not declared or explained, creating a mismatch between what the skill says it needs and what its instructions assume.

Persistence & Privilege

Although always:false (so not force-installed), the instructions explicitly ask to set persistent system crontab entries and place reminder scripts under /root — actions that require elevated privileges and produce long‑lived side effects. The skill neither declares needing those privileges nor documents explicit consent/authorization steps.

What to consider before installing

This skill largely implements a CET‑6 spaced repetition vocabulary tool and the shipped word lists and algorithm docs look benign. However, the runtime docs tell the agent to add crontab entries and drop/execute reminder scripts under /root and to call an OpenClaw CLI to send messages — actions that modify system scheduling and can send messages on your behalf. Also note a copy/paste inconsistency: schedule docs reference CET‑4 and /root paths, suggesting the author reused material without tailoring it. Before installing or enabling this skill: (1) confirm whether it truly needs to modify crontab and which user account will own the scheduled jobs; (2) require the skill to use per‑user paths (not /root) or to ask for explicit consent before creating system cron jobs; (3) verify presence and safety of any CLI it calls (openclaw) and ask the author to declare required binaries and any credentials; (4) review/modify the reminder script template so it does not leak user IDs or send messages to external targets without consent; and (5) consider running the skill in a sandbox/environment where it cannot modify system crontab until you trust it. If the author cannot justify the scheduling/privilege steps or provide safer per‑user alternatives, treat this skill as risky.

CET-6 单词记忆系统

快速开始

用户说"开始背六级单词"时：

1. 检查 references/user_schedule.csv 中是否存在用户记录
2. 存在 → 直接进入学习流程
3. 不存在 → 引导首次设置

首次设置流程：

• 询问每日学习时间（如 8:00、21:00）
• 询问每次学习数量（建议 8-15 个，六级词汇量大）
• 写入 user_schedule.csv
• 设置定时任务

核心流程

学习新单词

1. 从 references/cet6-vocabulary.md 排除已学单词
2. 随机选取用户计划数量
3. 展示：音标、词性、中文释义、例句（六级强调例句理解）
4. 用户说"完成" → 进入测验

单词测验

三种测验方式：

• 拼写测验：展示中文，让用户拼写英文
• 选择测验：展示英文，选择中文释义
• 翻译测验：展示例句，让用户翻译（六级重点）

答错的单词标记为"需重新记忆"，循环测验直到掌握。

复习单词

触发：定时任务或用户说"复习六级单词"

查询 word_memory_status.csv 中 next_review_date <= 今天 的单词，按复习流程处理。
