Version: 0.1.2 Axioma Tools
Validates IBANs using the mod-97 algorithm with country-specific length checks.
What this skill does
- Mod-97 checksum validation
- Country-specific length check (FR=27, DE=22, GB=22, etc.)
- Strips spaces/dashes from input
- Returns BBAN breakdown
When to use this skill
- ✅ Validate IBAN before payment submission
- ✅ Audit customer bank data
- ✅ Pre-validate in payment forms
- ❌ Verify if the account actually exists (separate API)
Usage
python3 axiom_iban_validator.py "FR76 3000 6000 0112 3456 7890 189"
python3 axiom_iban_validator.py --country FR --number "3000600011234567890189"
from axiom_iban_validator import validate_iban
validate_iban('FR7630006000011234567890189') # True
# Returns: {valid, country, bban, checksum_ok, length_ok}

Usage Guidance
Install only if you want maintainer-oriented ClawHub and Convex workflows. Review commands before running them, especially admin moderation, production migration, GitHub posting, and the autoreview helper; use the helper's no-yolo option if you do not want nested Codex to run with full sandbox bypass.
Capability Assessment
Purpose & Capability
The skills focus on ClawHub moderation, PR maintenance, Convex setup/performance/migrations, and code review; the documented commands match those stated purposes.
Instruction Scope
Some workflows have high impact, including admin moderation, production migrations, GitHub actions, and nested code review, but the instructions generally require explicit targets, reasons, confirmation, dry runs, verification, or existing auth.
Install Mechanism
The skill artifacts are mostly Markdown guidance plus reference files/icons; the only notable executable helper is the disclosed autoreview script, with no hidden installer or obfuscated setup found.
Credentials
These skills are proportionate for ClawHub maintainers or Convex developers with the expected repo tools and permissions, but they are not appropriate for casual users without that operational context.
Persistence & Privilege
No autonomous persistence was found. The autoreview helper can run nested Codex with full-access sandbox bypass by default, but this is disclosed and user-invoked with an opt-out flag.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install axiom-iban-validator - After installation, invoke the skill by name or use
/axiom-iban-validator - Provide required inputs per the skill's parameter spec and get structured output
