Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 2 findings, up to high
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 →

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 | $0.00139 | $0.07403 |
| Opus 5 | $0.00069 | $0.03701 |
| Sonnet 5 | $0.00028 | $0.01481 |
| Haiku 4.5 | $0.00014 | $0.00740 |
Grade A, and why
skills-il-skill-creator 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Skills-IL Skill Creator
Overview
This skill walks you through creating a production-quality skill for the skills-il organization. It follows Anthropic's Complete Guide to Building Skills and enforces all skills-il conventions.
Every skill you create will include: SKILL.md with validated frontmatter, bilingual metadata (Hebrew + English), step-by-step instructions with tables and code examples, a Hebrew companion file (SKILL_HE.md), and pass all validation checks.
Instructions
Step 1: Choose Category Repository
Ask the user which category repo this skill belongs to:
| Category | Repo | Focus Area |
|---|---|---|
| Tax & Finance | tax-and-finance | Invoicing, payroll, VAT, payments, pensions |
| Government | government-services | data.gov.il, Bituach Leumi, Rasham, transit |
| Security | security-compliance | Privacy law, cybersecurity, legal research |
| Localization | localization | RTL, Hebrew NLP, OCR, Shabbat scheduling |
| Dev Tools | developer-tools | ID validation, date conversion, phone formatting |
| Communication | communication | SMS, WhatsApp, Monday.com, job market |
| Food & Dining | food-and-dining | Restaurants, recipes, kashrut, delivery |
| Legal Tech | legal-tech | Contracts, legal research, compliance |
| Marketing & Growth | marketing-growth | SEO, social media, ads, email campaigns, ASO |
| Education | education | Learning platforms, tutoring, academic tools |
| Health Services | health-services | HMOs, pharmacy, medical records, appointments |
| Accounting | accounting | Bookkeeping, financial reporting, audit, accountant tooling |
| Travel | travel | Trip planning, flights, destinations, travel rights |
All 13 category repos use master as their default branch (not main). The full path format for github_url is https://github.com/skills-il/<repo>/tree/master/<slug>.
If the skill doesn't fit any category, discuss with the user whether it belongs in an existing category or warrants a new repo.
Step 2: Collect Creator Information (MUST ASK)
What ships with it
7 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.
