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 | $0.00052 | $0.02234 |
| Opus 5 | $0.00026 | $0.01117 |
| Sonnet 5 | $0.00010 | $0.00447 |
| Haiku 4.5 | $0.00005 | $0.00223 |
Grade A, and why
taiwan-calendar 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 320 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Taiwan Calendar Skill
Provides accurate Taiwan working day and holiday information by querying government open data APIs in real-time.
Why This Skill Exists
Claude Code frequently makes errors with Taiwan date-related queries due to knowledge cutoff:
- Gets weekdays wrong (e.g., saying Tuesday when it's Wednesday)
- Doesn't know current year's national holidays
- Unaware of make-up workdays (補班日)
This skill queries Taiwan's government administrative calendar API to provide accurate, up-to-date information.
When to Use
Trigger actively when user asks about:
- Date queries: "今天是幾號?", "What's today's date?", "現在台灣幾點?"
- Working day queries: "今天是工作日嗎?", "Is tomorrow a working day?", "下週一要上班嗎?"
- Holiday queries: "1/1 是假日嗎?", "國慶日是哪天?", "下一個連假什麼時候?"
- Date calculations: "5 個工作日後是哪天?", "這個月有幾個工作日?", "deadline 是五個工作天"
- Make-up workdays: "有沒有補班?", "這週六要上班嗎?"
Also use for:
- Schedule/timeline planning that requires working day awareness
- Deadline calculations mentioning "工作日/工作天"
- Any Taiwan calendar-related questions
Commands
All commands use: uv run --managed-python ${CLAUDE_SKILL_DIR}/scripts/taiwan_calendar.py <command>
Basic Queries
today - Today's date and status
uv run --managed-python ${CLAUDE_SKILL_DIR}/scripts/taiwan_calendar.py today
Output example:
2025-01-06 (週一) 是工作日。
check <date> - Check specific date
uv run --managed-python ${CLAUDE_SKILL_DIR}/scripts/taiwan_calendar.py check 2025-01-01
uv run --managed-python ${CLAUDE_SKILL_DIR}/scripts/taiwan_calendar.py check 01/01
Output example:
2025-01-01 (週三) 是非工作日 - 元旦。
Date formats supported:
YYYY-MM-DD(e.g., 2025-01-01)YYYY/MM/DD(e.g., 2025/01/01)MM/DD(assumes current year, e.g., 01/01)
Range Queries
range <start> <end> - Count working days in range
uv run --managed-python ${CLAUDE_SKILL_DIR}/scripts/taiwan_calendar.py range 2025-01-01 2025-01-31
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.

taiwan-calendar is a skill published in the GitHub repository pigfoot/claude-code-hubs (5 stars, last pushed 1mo ago), licensed MIT. It adds 52 tokens to every session and 2,234 once invoked, about $0.0003 per session on Opus 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.
