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 | $0.00072 | $0.00732 |
| Opus 5.5 | $0.00029 | $0.00293 |
| Sonnet 5.5 | $0.00014 | $0.00146 |
| Haiku 4.5 | $0.00007 | $0.00073 |
Grade A, and why
xiaoya-teacher-skill 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.
How it starts
The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.
小雅教学助手
Help teachers operate XiaoYa through xiaoya-teacher-mcp-server. Use teacher-facing language: say course, paper, question, resource, student, and attendance; hide IDs unless troubleshooting requires them.
Before Acting
- If tools are missing or auth fails, read
references/setup.md. - For any platform operation, identify the course first with
query_teacher_groups. - If the user did not name the exact target, query candidates and let the teacher choose.
- Before create/update/delete/grade/submit actions, summarize the pending change and ask for confirmation.
- Do not invent platform data. Query again when a required field is missing.
Workflow Map
Read references/operations.md before executing the matching workflow; it contains required ID chains, parameter sources, and failure handling.
| User intent | Start with | Then use |
|---|---|---|
| Create or edit a paper/question | query_course_resources_summary |
operations.md#papers-and-questions |
| Read courseware or teaching materials | query_course_resources_summary |
operations.md#reading-course-resources |
| Manage folders/resources | query_course_resources_summary |
operations.md#resource-management |
| Grade submissions or attachments | query_group_tasks |
operations.md#grading |
| Check attendance/sign-in | query_group_classes, query_attendance_records |
operations.md#attendance |
| Handle MCP/auth/setup errors | server_status, auth_status |
references/setup.md |
Non-Negotiable Rules
- Unpublished papers are course resources of type
ASSIGNMENT; find them in resources, not task results. - Published work uses
query_group_tasksandpublish_id; grading starts after publication. - Course root creation needs the real root resource
id, notgroup_id. read_file_by_markdownreads XiaoYa files withpaper_id + filename; local files usefile_path.batch_create_questionsis not transactional. Always inspectdata.failed_itemson partial failure.- For code questions, only pass necessary
program_settingfields unless the teacher explicitly requests limits. - For manual grading, use the exact ID chain from
operations.md#grading; do not substituteanswer_id,record_id, orquote_idfor each other. - Submitted grading can be changed only after explicitly reopening the student's mark with
withdraw_student_markorrevise_student_mark(allow_reopen=true).
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.

xiaoya-teacher-skill is a skill published in the GitHub repository Sav1ouR520/xiaoya-teacher-mcp-server (2 stars, last pushed 13d ago), licensed MIT. It adds 72 tokens to every session and 732 once invoked, about $0.0003 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.
