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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 258 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00141 | $0.07723 |
| Opus 5.5 | $0.00056 | $0.03089 |
| Sonnet 5.5 | $0.00028 | $0.01545 |
| Haiku 4.5 | $0.00014 | $0.00772 |
Grade B, and why
israeli-utility-rates-comparator scanned grade B 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 8d 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.

Israeli Utility & Telecom Rates Comparator
Instructions
Step 1: Identify Which Utility to Compare
Establish which bill the user wants to move; the levers differ sharply. Electricity, water and
cooking gas are national or near-national and barely change with location, arnona changes with the
municipality, telecom with the provider. Ask for the last three bills, and where a household has
several, start with the largest line rather than the one they mentioned. Market-structure
background, including who owns which telecom brand, is in references/details-2026.md.
Step 2: Electricity Comparison
Understanding IEC tariff structure:
The Electricity Authority sets the tariffs. A household is on the flat tariff (one rate for all hours) or on time-of-use (תעו"ז), which needs a smart meter, has only two bands, peak and off-peak, since the new clusters were first applied on 1.1.2023 (decision 63609), and has THREE seasons, each with its own rates:
| Season | Peak band | Peak (agorot/kWh, incl. VAT) | Off-peak |
|---|---|---|---|
| Summer (Jun-Sep) | 17:00-23:00 | 172.23 (145.96 excl. VAT) | 50.42 |
| Winter (Dec-Feb) | 17:00-22:00 | 114.70 | 46.63 |
| Transition (Mar-May, Oct-Nov) | see note | 49.58 | 45.78 |
- In force from 1.7.2026, re-verified against the IEC low-voltage TOU page on 19 October 2026: all three seasons and both VAT bases still match, and no newer edition had been published.
- Peak applies on different days per season, and this is where most of the money is. In SUMMER and in TRANSITION there is NO peak band at all on Fridays, holiday eves, Shabbat or holidays: the whole day is off-peak. In WINTER the peak band applies on every day including Shabbat and holidays. There is no morning peak in any season.
- For TOU purposes these holidays count as Shabbat, and their eves as Friday: Rosh Hashana, Yom Kippur, the first day of Sukkot, Simchat Torah, the first and seventh days of Pesach, Independence Day and Shavuot. The hours are Israel local time and the metering equipment is adjusted when summer time is in force.
- Do not quote transition-season band hours: the IEC page states them in a garbled form ("22:00-17:00").
- Is TOU worth it? Compare the flat 63.52 with the household's blended TOU rate per season, then net off the fixed charges: on a bi-monthly single-phase connection TOU distribution is 37.88 against 11.76 on the flat tariff, about 26 ILS more per bill. In transition even the TOU peak (49.58) is below the flat rate; summer turns on how much load sits in weekday 17:00-23:00. Never quote a flat percentage saving.
What ships with it
6 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.

israeli-utility-rates-comparator is a skill published in the GitHub repository skills-il/tax-and-finance (38 stars, last pushed yesterday), licensed MIT. It adds 141 tokens to every session and 7,723 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it B with 1 finding (subtle steering). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
