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 | $0.00112 | $0.02284 |
| Opus 5.5 | $0.00045 | $0.00914 |
| Sonnet 5.5 | $0.00022 | $0.00457 |
| Haiku 4.5 | $0.00011 | $0.00228 |
Grade A, and why
shekel-currency-converter 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.

Shekel Currency Converter
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: {"key":"USD","currentExchangeRate":2.872,"unit":1,"currentChange":1.66,"lastUpdate":"..."}. Here currentChange is a percentage daily move, not an absolute NIS delta, and it is NOT used in conversion math.
Historical / tax-date rate (SDMX series):
The JSON endpoint's ?date= parameter is IGNORED, it always returns today's rate. For a specific past date (the rate that matters for tax), use the Bank of Israel SDMX EXR series instead:
Fetch: https://edge.boi.gov.il/FusionEdgeServer/sdmx/v2/data/dataflow/BOI.STATISTICS/EXR/1.0/RER_<CUR>_ILS?startPeriod=YYYY-MM-DD&endPeriod=YYYY-MM-DD&format=csv
Replace <CUR> with the currency code (e.g., RER_USD_ILS, RER_EUR_ILS).
Parse CSV: read OBS_VALUE keyed by TIME_PERIOD.
The series omits non-publication days (Saturday, Sunday, holidays). If there is no row for the exact requested date, walk back to the most recent published date on or before it, and tell the user which date's rate you used.
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.
- 1mo ago First seen · 140 lines · 112 tokens per session scan A 78727c66deec
shekel-currency-converter is a skill published in the GitHub repository squadcodercom/squadcoder (12 stars, last pushed 3mo ago), licensed MIT. It adds 112 tokens to every session and 2,284 once invoked, about $0.0004 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 2026-09-03.
