Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00048 | $0.00463 |
| Opus 5.5 | $0.00019 | $0.00185 |
| Sonnet 5.5 | $0.00010 | $0.00093 |
| Haiku 4.5 | $0.00005 | $0.00046 |
Grade A, and why
practice-drill 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 1mo 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.
What it actually says
出题刷题（精进练习）
面向「想多练、精进」的学习者，按掌握度出难度合适的题，练完交批改，形成「练 → 批 → 复习」循环。
执行流程
- 读画像 + 掌握状态：确定当前水平（新手/熟练）、目标语言、已掌握点与薄弱点。
- 选题：新手出「刚学概念的巩固题」；熟练者出「变体题、迁移题、跨概念综合题、小项目改造」。
- 难度对齐掌握度：太简单浪费时间，太难挫败；熟练者优先给 L5 迁移题（结构相同、表面不同，独立完成才算掌握）。
- 出题要「能验证」：每题带明确完成标准 + 预期输出/行为，练完能自己判断对错。
- 做完 → 交
assignment-review批改；正确推进掌握，错误记录误区并降级重练。 - 长期精进：结合
spaced-review的到期复习点 +project-practice的变体改造，持续循环。
边界
- 一次只展示一道练习，做完、评价完再给下一题；题库可以提前生成，但不能一次抛给学习者。
- 跳过不算答对，也不能触发掌握推进或庆祝反馈。
- 不提前给答案；卡住转
exercise-coach给最小提示。 - 题目基于 curriculum 原子/概念图，不编造超纲内容。
- 只记录真实完成的练习证据；不得伪造「已做完」。
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.
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.

practice-drill is a skill published in the GitHub repository yyz666ai/Learning-Agent (0 stars, last pushed 1mo ago), licensed MIT. It adds 48 tokens to every session and 463 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
skillpack-creator
Create a reusable SkillPack from a successful completed task. Use when the user wants to convert a one-off research, coding, analysis, or content workflow into a distributable local SkillPack with skillpack.json, local skills under skills/, starter prompts, start scripts, and an optional zip package.
skill-creator
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
goga-discover
Interview the user relentlessly about a decision until every branch of the design tree is resolved, then record the result as a short ADR.
commit
Atomic git commit with conventional message. Use when the user says "commit", "save my changes", "commit this", or wants to create a git commit. Stages specific files, writes a conventional commit message with body explaining non-obvious decisions. Never uses git add -A.
python-run
Run and debug Python scripts in the project. Use when the user says "run python", "execute this script", "debug this py file", or wants to run/modify a .py file. Handles dependency checks, linting, execution, and error analysis.
akirule
Aki's contextual rule router — route EVERY task turn before acting, by what the task means (the domain it touches and the kind of act — write, decide, audit, ship), with listed signals as evidence, never as the test. Domains: code quality and structure (any code file), docs and any .md, UI copy and i18n, frontend…
