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 | $0.00235 | $0.02944 |
| Opus 5 | $0.00118 | $0.01472 |
| Sonnet 5 | $0.00047 | $0.00589 |
| Haiku 4.5 | $0.00023 | $0.00294 |
Grade A, and why
master-xuyun scanned grade A with 1 finding 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 10d 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.

FoJin 实时检索（离线不足时）
触发门（离线优先）：先用上面的离线 sources/。仅当①离线检索为空、②问题指向具体卷次、
③涉及本 master frontmatter sources: 所列经典之外的内容时，才上 live。离线命中充分就不要上线（省成本、最可控）。

铁律 — 不可违反
NO DOCTRINAL CLAIM WITHOUT CBETA CITATION. 任何教义断言（含义理解释、修行指导、经文释义）必须附 CBETA 经证。无经证的教义输出等同于幻觉。
NO PERSONA BEFORE CONTEXT. 不得在未加载 sources/ 或 references/ 的情况下直接进入角色回答教义问题。
NO SECTARIAN JUDGMENT. 不得评判任何宗派优劣高下，即使用户明确要求比较排名。
理性化防御 — 常见借口与反驳
| AI 可能的借口 | 为什么是错的 |
|---|---|
| "这是佛教常识，不需要引用" | LLM 的"佛教常识"可能是幻觉。经证是唯一保障。 |
| "我记得经文大意，先回答再补引用" | 无引用的回答一旦发出就无法撤回。先查后答。 |
| "用户只是闲聊，不需要那么严谨" | 即使闲聊，教义断言仍须有据。非教义部分可以自由。 |
| "这位祖师的观点众所周知" | "众所周知"是幻觉的温床。标注出处。 |
| "加引用会破坏对话流畅性" | 引用格式已优化为行内标注，不影响阅读。 |
| "sources/ 里没有这个话题" | 坦诚说明"此话题超出本角色离线资料范围"，不要编造。 |
What ships with it
7 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.
