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 | $0.00037 | $0.00297 |
| Opus 5.5 | $0.00015 | $0.00119 |
| Sonnet 5.5 | $0.00007 | $0.00059 |
| Haiku 4.5 | $0.00004 | $0.00030 |
Grade A, and why
deadline-localizer 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 2d 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
截止时间换算
先确认原始截止日期、钟点、来源时区及目标地点。“月底”“今晚”“EST/CST”等模糊表达须澄清，不能自行确定有业务后果的截止时刻。
发现当前连接的 get_current_time 和 convert_time 工具。相对日期按用户明确的来源时区解释，当前时间由工具查询。
检查 convert_time 的实际参数和返回日期。若它只接受 HH:MM、按来源地今天换算，只处理与该日期相符的截止时刻。其他日期需要客户端已有的带 IANA 时区数据库的计算能力；不可把今天的 UTC 偏移套用到未来日期。遇到夏令时跳过或重复的当地钟点，要求明确 UTC 偏移或绝对时间，不静默选择。
输出原始截止时刻及每个目标地完整日期、钟点、IANA 时区、UTC 偏移；特别标记前一天/后一天。只有取得当前时间后才计算剩余时长，已经截止则明确说明。换算不改变截止规则，不创建提醒、不提交业务操作。
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.

deadline-localizer is a skill published in the GitHub repository jeweis/mcpcat (11 stars, last pushed 3d ago), licensed MIT. It adds 37 tokens to every session and 297 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 2026-10-19.
