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 | $0.00073 | $0.08453 |
| Opus 5.5 | $0.00029 | $0.03381 |
| Sonnet 5.5 | $0.00015 | $0.01691 |
| Haiku 4.5 | $0.00007 | $0.00845 |
Grade A, and why
persian-number-utility 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 6d 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.

Persian Number Utility — Flutter Skill
Purpose
This skill provides authoritative, production-grade engineering instructions for integrating, formatting, normalizing, validating, and testing Persian numbers, words, dates, currency, and Iranian identifiers in Flutter applications using the persian_number_utility package (v1.1.6).
When to Use This Skill
- Formatting numbers, dates, currency amounts, or card numbers into Persian digits (
۱۲۳) and separated groups (۱۰۰,۰۰۰). - Converting numbers to Persian words (e.g.,
1000->یک هزار) or words back to integers (toNumber()). - Validating Iranian syntactic formats: National Code (کد ملی), Bank Card (شماره کارت), Mobile Number (شماره موبایل), Postal Code (کد پستی), and Sheba (شبا).
- Normalizing user input containing mixed Persian (
۰-۹), Arabic (٠-٩), and Latin (0-9) digits into canonical ASCII for backend storage or parsing. - Converting Gregorian
DateTimeto Jalali/Shamsi (هجری شمسی) representation and relative time strings.
When NOT to Use This Package
- Authoritative Identity or Bank Account Verification: Client-side checksums cannot verify if a national code belongs to a living person or if a bank card is active. Use authenticated backend APIs.
- Complex Financial / Ledger Calculations:
beToman()converts viadoubledivision (/ 10), introducing IEEE-754 precision issues. Use integer math in lowest denomination orpackage:decimal. - Complete App Internationalization (i18n): This package does not check
Localizations.localeOf(context). It unconditionally produces Persian strings. For locale-aware formatting, useintl(NumberFormat). - Full-featured Solar Hijri Calendars: For calendar math, leap-year calculations, date arithmetic, or date picking, prefer
shamsi_dateor dedicated calendar engines.

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.

persian-number-utility is a skill published in the GitHub repository ariaramin/flutter-skills (6 stars, last pushed 6d ago), licensed MIT. It adds 73 tokens to every session and 8,453 once invoked, about $0.0003 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 2026-10-11.
