安全使用建议
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.
功能分析
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.
能力评估
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.
