Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00044 | $0.00979 |
| Opus 5 | $0.00022 | $0.00490 |
| Sonnet 5 | $0.00009 | $0.00196 |
| Haiku 4.5 | $0.00004 | $0.00098 |
Grade A, and why
ielts-practice 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 today.
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
IELTS Buddy 练习接口
本 Skill 只说明浏览器练习相关的目录和只读记录接口。个人数据调用前，先按Agent API 配置绑定并检查能力。
接口
| 能力 | 数据或动作 | 调用约束 |
|---|---|---|
ielts_prediction_search_hits |
公开考场记录及可能对应的题目 | 可无需 Token；保留来源和回忆信息，只使用服务端返回的候选题及可选练习入口。 |
ielts_practice_list_taxonomy、ielts_practice_search_parts、ielts_practice_read_part |
题库分类、目录和非答案内容 | 不在聊天中复刻完整试题。 |
ielts_dictation_search_materials |
可逐句精听的听力素材目录与 contentRef |
只返回素材事实，不创建精听运行或浏览器入口。 |
ielts_practice_recent_activity、ielts_practice_read_session |
当前账号 session 状态 | 只读取当前账号数据。 |
ielts_review_read_snapshot |
已提交 session 的作答、答案 key 和可选材料 | 服务端不提供错因、证据或教学结论。 |

边界
- 一条预测命中结果由“考场记录”和
candidates两层组成。source、title、recallContent、日期与考点属于来源记录，不能与候选题合并成同一事实。 candidates是可能对应的题目，matchScore只表示匹配值，不代表来源平台确认命中。展示时保留服务端返回的全部候选，不只取第一项，也不自行设置第二层阈值。- 候选题的
practiceUrl是可选项；只有非空时才提供做题入口。没有做题入口不影响考场记录或候选题本身的有效性。 - 三个月以前的考场记录仍可查询，但服务端不再对其执行题库匹配；返回空
candidates属于正常结果。 - Token 只用于数据接口；浏览器网页登录态只用于练习页面，两者不可互换。
- Agent 不创建、填写或提交正式练习；用户在浏览器刷题中心手动开始、作答和交卷，Agent 在完成后读取权威记录。
- 题库来源只使用
search_parts返回的origin.questionBank、origin.sourceBook、origin.sourceTest和origin.sourceUnit；不要从标题或普通标签推断来源。 - 本 Skill 不定义选题、诊断、复盘或学习计划。
workflows/是独立的可选推荐层，不属于本 Skill 的接口契约。
列表与详情
查询学习记录分两步：先读取列表摘要，再按需用返回的 reviewTarget 调用 ielts_review_read_snapshot 查看某次练习或某个已完成模考科目的详情；精听使用 attemptId 调用 ielts_dictation_read_attempt，未提交普通练习使用 sessionId 调用 ielts_practice_read_session。不要为了列出记录逐条展开详情。使用前以当前账号的 capabilities 为准。
列表中的 sessionId 是练习次数，partId 是不同篇目；区分零作答、已作答未提交和已提交，不从部分题目的正确率推算 IELTS 分数。需要完整记录时按 nextOffset、nextCursor 或 nextPage 翻页，直到 hasMore=false；空页有后续游标时仍需继续。observationTruncated=true 或 coverage.sourceTruncated=true 表示数据仍不完整，不得声称查全。计划列表只含摘要，用 planId 调用 ielts_study_plans_get 获取任务页。
What ships with it
4 files 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.

ielts-practice is a skill published in the GitHub repository Jobo16/ielts-buddy (20 stars, last pushed yesterday), licensed MIT. It adds 44 tokens to every session and 979 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
