Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

english-explorer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

生成步骤

  1. 根据年龄段确定词汇难度(5-7 岁: 3-4 字母词, 7-9 岁: 5-6 字母词)
  2. 参考 assets/template.html 的三模式切换和交互逻辑
  3. 根据用户需求调整:
    • 词汇主题(动物/水果/颜色/数字/身体部位等)
    • 游戏模式(看图选词/听音选图/单词拼写)
    • 是否启用发音功能(Web Speech API)
    • 连击奖励和成就系统
    • 可增加中文提示辅助学习
  4. 调用 generateGame 生成完整 HTML
  5. 调用 evaluateGame 检查质量

评估重点

  • 词汇内容适合目标年龄段
  • 三种游戏模式都能正常运行
  • 看图选词:图片/emoji 与选项匹配

  • 拼写验证不准确 → 将用户输入和正确答案都 trim() 并 toLowerCase() 后再比较
  • 提示音效无法播放 → 浏览器自动播放策略限制,需在用户交互后才能播放音频,添加 click 事件触发

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
