Daily Brain — 每日脑力训练
每天一道精选脑力题，逻辑/数学/记忆/文字四类轮换，难度自适应，打卡追踪成就
Purpose & Capability
daily-brain 是一个每日认知训练技能，通过游戏化的脑力题目帮助用户保持思维敏锐。
核心能力：
| 能力 | 说明 |
|---|---|
| 四类题目轮换 | 逻辑推理、数学速算、记忆挑战、文字谜题，按日期自动轮换 |
| 难度自适应 | Easy/Medium/Hard 三档，根据连续正确率自动调整 |
| 精美视觉卡片 | HTML 格式题目卡片和解析卡片，支持浅色/深色主题 |
| 打卡追踪 | 连续天数、最长纪录、正确率、类别分布统计 |
| 成就系统 | 解锁里程碑徽章（首次答题、连续7天、满分周等） |
| 答案解析 | 每题配详细解题思路和知识扩展 |
能力边界（不做的事）：
- 不联网获取题目 — 全部题库内置，无需 API
- 不生成实时竞技或多人对战
- 不提供专业心理学/医学认知评估
- 不修改任何系统设置或 shell 配置

Usage Guidance
This skill appears to do what it claims: present daily puzzles from an embedded DB and store progress locally. Before installing, ensure you have Node.js (>=18) available and that you are comfortable with a local file (data/progress.json) storing your progress unencrypted. Review the small JS files if you want assurance (they contain no network calls or secret access). Note the puzzle-data minor inconsistency (L001 has conflicting answer fields) — that's a correctness/UX issue, not a security issue. If you prefer extra safety, run the skill in a restricted environment or container, or back up/delete data/progress.json before/after use.
Capability Analysis
Type: OpenClaw Skill
Name: daily-brain
Version: 1.0.0
The daily-brain skill is a self-contained puzzle game that manages logic, math, and memory challenges locally. The Node.js scripts (answer.js, stats.js, today.js) perform standard file I/O restricted to the skill's own data directory to track user progress and achievements. There is no evidence of network activity, unauthorized file access, or malicious prompt injection; the instructions provided to the AI agent are strictly limited to formatting HTML visual cards for the user interface.
Capability Assessment
Purpose & Capability
Name/description match the implementation: puzzles are embedded in data/puzzles.json; scripts produce today's puzzle, accept answers, update local progress, and render HTML card instructions. The node >=18 requirement declared in SKILL.md aligns with the provided JavaScript files.
Instruction Scope
SKILL.md explicitly states no networking or credential access; the scripts follow that and only read/write files under the skill's data directory. Minor content inconsistencies exist in the data: e.g., puzzle L001 lists 'answer': 'B' but has 'correctedAnswer': 'A' (the code prefers correctedAnswer when present). This is a data correctness issue, not a security concern.
Install Mechanism
No install spec; skill is instruction-only with local JS files. No downloads, package installs, or archive extraction occur. The recommended manual install (copy into skills dir) is low-risk and consistent with the skill's declared behavior.
Credentials
The skill requests no environment variables or credentials and does not access system config paths. Its only persistent data is data/progress.json inside the skill; that is proportionate to a local progress-tracking puzzle skill.
Persistence & Privilege
The skill writes only a single local file (data/progress.json) and documents its uninstall path. always:false and normal autonomous invocation are set. It does not request elevated privileges, modify other skills, nor write outside its own directory.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install daily-brain - After installation, invoke the skill by name or use
/daily-brain - Provide required inputs per the skill's parameter spec and get structured output
