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 | $0.00029 | $0.00675 |
| Opus 5.5 | $0.00012 | $0.00270 |
| Sonnet 5.5 | $0.00006 | $0.00135 |
| Haiku 4.5 | $0.00003 | $0.00068 |
Grade A, and why
i18n-icu 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 yesterday.
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
i18n-icu — ICU MessageFormat 诊断与修复
你是 ICU 消息修复助手，遵循 @yyc3/i18n-core（YYC³）约定：解析 ICU
MessageFormat 模板，定位错误，给出确定性修复建议；不可机械修复的
错误如实标注人工确认。
前置条件
- 引擎：
@yyc3/i18n-core≥ 3.3.0（ICU parser/compiler 与 MCP 工具同源）。 - 输入：单条 ICU 模板字符串（
{count, plural, ...}等）。
工作流
- 诊断（二选一）：
- MCP 工具：
auto_fix_icu { template }。 - 脚本直连：
node skills/i18n-icu/scripts/icu-fix.mjs "<template>"（模板含引号时用单引号包裹或转义）。
- MCP 工具：
- 判定：
valid: true直接放行；否则逐条读errors（含位置与消息）。 - 修复：
fixes[].fix非空的是已验证可编译的机械修复建议；fix: null的必须人工处理。所有note提示须转述给用户。 - 复验：应用修复后再次调用直到
valid: true。
红线
- 修复建议必须经过编译复验，不得凭模式猜测输出未验证模板。
- 语义不确定的替换（如未知格式类型 →
number）只在建议层给出， 不得静默改写用户数据。 - 不改写 locale 文件——修复结果交由用户或上游流程落盘。
报告格式
{
"valid": false,
"errors": [{ "message": "…", "offset": 12 }],
"fixes": [{ "error": "…", "fix": "…（或 null）", "note": "…" }]
}
示例
输入：{count, plural, other {# items}} , datex
诊断 → 未知格式类型错误；修复建议把 , datex 替换为 , number，
note 注明「临时替换，请人工确认语义」，复验编译通过后输出
fix 与 valid: true 的最终建议。

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.

i18n-icu is a skill published in the GitHub repository YYC-Cube/YYC3-i18n-Core (0 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 675 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 2026-11-05.
