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 124 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 | $0.00130 | $0.06406 |
| Opus 5 | $0.00065 | $0.03203 |
| Sonnet 5 | $0.00026 | $0.01281 |
| Haiku 4.5 | $0.00013 | $0.00641 |
Grade A, and why
israeli-customs-duty-calculator 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.
How it starts
The opening of the file, as written. The whole thing — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Israeli Customs Duty Calculator
Legal notice
This is a free information tool operated by an AI model. It explains the rules and calculates from the figures you enter, but it does not examine your full circumstances and does not constitute customs or tax advice. All of its outputs are produced automatically, with no involvement, review, or approval by a customs agent or tax adviser, and an AI model may err, omit data, or present a wrong conclusion. The binding classification and charge are determined by the Tax Authority at import. This tool is not a substitute for advice that takes account of the particular circumstances and needs of each person, and all use of its output is the user's sole responsibility.
Problem
Importing goods into Israel (whether a single Amazon order or a commercial shipment) triggers up to three separate taxes: customs duty, VAT, and purchase tax (mas kniya). Thresholds shift (the personal exemption moved from $75 to $150 in December 2025, was annulled back to $75 by the Knesset on 24 February 2026, and was re-set to $130 by a new Finance Ministry order the next day, and reverted to $75 after that window ran to 1 June 2026), duty depends on an 8-digit HS code that is not the same as the US or EU code, and free-trade preferences only help when you produce the right origin proof. Buyers constantly over- or under-estimate the landed cost.
Instructions
Step 1: Identify the import type
| Type | Typical user | Tax treatment |
|---|---|---|
| Personal import, small parcel | Consumer ordering online | Exemption threshold applies (see Step 2) |
| Personal import, high-value | Consumer buying jewelry, electronics | VAT applies; some goods also owe duty and purchase tax depending on the HS code (see Step 2) |
| Commercial import (B2B) | Osek Murshe importing stock | Full duty + VAT, no threshold exemption. Import VAT is recoverable as input tax, but only against a rashimon that identifies the importer as the taxable person; check with your bookkeeper how the rashimon is made out before assuming recovery. This skill does not verify the input-tax rule |
| Gift | Individual sending to an Israeli | Treated as personal import, no special exemption |
| Aliyah, oleh hadash or toshav chozer belongings | New immigrant or returning resident | A separate personal-effects exemption this skill does not compute. Take it to a customs broker or the customs house; do not use the commercial row |

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.
