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 | $0.00053 | $0.00154 |
| Opus 5.5 | $0.00021 | $0.00062 |
| Sonnet 5.5 | $0.00011 | $0.00031 |
| Haiku 4.5 | $0.00005 | $0.00015 |
Grade A, and why
textbook-qa 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
Textbook QA
- Call
rag_statuswhen source scope or index readiness is not already established. - Call
textbook_qawith the user's exact question and the requested answer depth. - Lead with a direct answer, then cite the returned relative source paths and headings.
- Separate retrieved source claims from your explanation or outside knowledge.
- State what the evidence does not establish; do not treat a high retrieval score as proof of completeness.
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.

clinical-q-and-a
A fast path for answering general educational medical questions and correcting common misconceptions, with a light check against one current authoritative guideline or consensus.
guideline-section-expansion
A learning aid for expanding sections of medical guidelines or turning them into a study path. The source text is in Chinese, but the skill requires verified official documents before producing learning content.
guideline-learning-diagnosis
A study aid for learning a medical guideline or its diagnostic criteria. It helps assess what someone knows, find weak sections, and plan further study without diagnosing a real patient.
insurance-policy-learning
A learning aid for studying regional health-insurance policies from official documents. It provides summaries, items to confirm locally, and authoritative sources rather than reimbursement decisions.
subscription-setup
A setup workflow for creating recurring medical-learning subscriptions after a doctor’s profile has been registered.
exam-material-recommendation
A study-material recommendation tool for doctors preparing for professional exams or job-related training. It uses the person’s target, timeline, available study time, and specialty, while treating the official exam syllabus as the main reference.
