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.

What it costs to keep this loaded
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 | $0.00152 | $0.05343 |
| Opus 5.5 | $0.00061 | $0.02137 |
| Sonnet 5.5 | $0.00030 | $0.01069 |
| Haiku 4.5 | $0.00015 | $0.00534 |
Grade A, and why
shekel-currency-converter 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 9d 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.

Shekel Currency Converter
Legal notice
This is a free information tool operated by an AI model. It retrieves the representative exchange rates the Bank of Israel publishes, converts amounts at them, and explains which date's rate the published rules point to. It does all of this without the involvement, review, or approval of a tax adviser or accountant. The output is not tax advice, not a filed return, and not a professional opinion, but published reference data and a general explanation only: it does not examine your books, your accounting basis, your VAT status or the full facts of your transaction. An AI model may err, omit data, or present a wrong conclusion.
Any figure or text this tool produces is for your personal preparation only. Responsibility for reporting and for paying the tax is yours, the binding computation is the Tax Authority's, and representation before the Tax Authority is reserved to those permitted by law. This tool is not a substitute for advice that takes account of the particular circumstances and needs of each person. Confirm with a tax adviser or accountant which date and rate apply to your transaction before filing or paying. All use of its output is the user's sole responsibility.
Instructions
Step 1: Identify Conversion Request
Parse the user's request for:
- Source currency and target currency (at least one should be NIS/ILS)
- Amount to convert
- Date (current or specific historical date, important for tax conversions)
- Purpose (general info vs. tax-relevant representative rate)
Common currency codes:
| Code | Currency | Hebrew |
|---|---|---|
| ILS | Israeli New Shekel | shekel chadash |
| USD | US Dollar | dolar |
| EUR | Euro | euro |
| GBP | British Pound | lira sterling |
| JPY | Japanese Yen | yen |
| CHF | Swiss Franc | frank shveitzi |
Step 2: Fetch Exchange Rate
Current rate (live JSON endpoint):
The legacy XML feed at currency.xml is gone (it now redirects to the JSON API), so do NOT parse XML. Fetch the JSON endpoint and read the exchangeRates array.
Fetch: https://www.boi.org.il/PublicApi/GetExchangeRates
Parse JSON: response.exchangeRates is an array of objects.
Each object: key (currency code), currentExchangeRate (NIS per "unit"),
unit (1, 10, or 100), currentChange (percent move vs. previous
publication), lastUpdate (ISO timestamp).
Example object (the 2026-10-16 publication, a Friday, stamped 12:22 Israel time): {"key":"USD","currentExchangeRate":3.089,"currentChange":-0.4511762810183693200128907500,"unit":1,"lastUpdate":"2026-10-16T09:22:04.9223221Z"}. Here currentChange is a percentage daily move, not an absolute NIS delta, and it is NOT used in conversion math.
What ships with it
8 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.

shekel-currency-converter is a skill published in the GitHub repository skills-il/tax-and-finance (38 stars, last pushed yesterday), licensed MIT. It adds 152 tokens to every session and 5,343 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
