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 | $0.00016 | $0.00473 |
| Opus 5.5 | $0.00006 | $0.00189 |
| Sonnet 5.5 | $0.00003 | $0.00095 |
| Haiku 4.5 | $0.00002 | $0.00047 |
Grade A, and why
typescript-strict-guard 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
TypeScript 严格类型防御准则
在生成任何 TypeScript 代码时，AI 必须严格执行零妥协（Zero-Tolerance）类型安全规则。
一、 铁律（Zero Tolerance）
- 严禁
any：绝对禁止直接或间接使用any。未知数据必须使用unknown并通过 Type Guard / Zod 校验收窄。 - 严禁不安全断言：禁止使用
as unknown as T或随意使用非空断言!（除非能严格证明其前置不变式）。 - 强制导出显式返回类型：所有导出的函数、类方法必须显式标注返回类型，严禁依赖隐式推导。
- 不可变数据优先：对象数组参数优先标注
readonly T[]或Readonly<T>，禁止在函数内直接 mutate 入参。
二、 核心设计模式要求
- Discriminated Unions（可辨识联合）：状态模型必须通过唯一的
kind/status/type字段进行状态分支隔离。 satisfies优于类型标注：在需要保留字面量类型且满足契约时，优先使用satisfies操作符。
三、 范例对比
- ❌ 反例:
function handleData(data: any) {
return (data as any).user.name!;
}
- ✅ 正例:
interface UserData {
user: { name: string };
}
function isUserData(obj: unknown): obj is UserData {
return typeof obj === "object" && obj !== null && "user" in obj;
}
export function handleData(raw: unknown): string {
if (!isUserData(raw)) throw new Error("Invalid payload");
return raw.user.name;
}
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.

typescript-strict-guard is a skill published in the GitHub repository 2428424081cn/Skill-mcp (1 stars, last pushed 2mo ago), licensed MIT. It adds 16 tokens to every session and 473 once invoked, about $0.0001 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.
