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 | $0.07701 |
| Opus 5 | $0.00071 | $0.03851 |
| Sonnet 5 | $0.00028 | $0.01540 |
| Haiku 4.5 | $0.00014 | $0.00770 |
Grade A, and why
israeli-utility-rates-comparator 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 12d 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.

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 publishes official tariffs at pua.gov.il. IEC tariffs for residential customers include:
Standard tariff (tariff achid):
- Single rate per kWh for all hours
- Simplest billing structure
- Suitable for low-medium consumption households
Time-of-use tariff (tariff TOZ / תעריף תעו"ז):
- Requires a smart meter (moné chokhéakh)
- Two tiers since April 2023: peak (shia) and off-peak (shefel). The shoulder (geva) tier was eliminated; older docs may still show 3 tiers.
- THREE seasons, each with its own peak and off-peak rate. Off-peak is not a single national number.
| 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 27 August 2026: all three seasons and both VAT bases still match.
- 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"). It rarely matters, the spread there is under 4 agorot.
- Savings are seasonal: shifting load off-peak is worth over 120 agorot/kWh in summer and under 4 in transition. Never quote a flat "15-25% saving"; compute it from the user's own seasonal pattern.
- Tariffs update semi-annually via Electricity Authority decisions and can shift mid-year; verify before quoting.
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 (34 stars, last pushed 3d ago), licensed MIT. It adds 141 tokens to every session and 7,701 once invoked, about $0.0007 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 2026-08-30.
