## Tools (11)

- `analyze_phone_number`: Analyze a number using versioned numbering metadata. National numbers need numberCountryCode; exit prefixes need originCountryCode. Reports uncertainty and rule
- `compare_phone_numbers`: Compare two numbers after analysis. Missing context produces indeterminate. Extensions must match unless extensionPolicy is explicitly ignore; equality does not
- `diagnose_dialing_problem`: Explain formatting issues and propose reviewed prefix repairs for confirmation. Uses the same analyzer. Cannot determine why a network rejected a call.
- `find_calling_windows`: Find overlapping working hours using explicit IANA time zones and dates. Handles overnight shifts and DST; never infers location from phone numbers or contacts 
- `format_international_phone_number`: Normalize a phone number into a plausible international format using reviewed country-specific rules. Processing is ephemeral. This tool does not query carriers
- `get_dialing_instructions`: Prepare origin-specific dialing guidance for reviewed countries. Provide origin and destination separately; no phone number returns safe placeholder patterns. N
- `get_phone_capabilities`: Discover supported countries, per-operation review coverage, evidence, dataset versions and request limits before choosing a phone workflow.
- `get_phone_input_rules`: Get reviewed display placeholders and trunk-prefix guidance. Examples are not validation masks. English fallback and unsupported editorial coverage are explicit
- `lookup_country_calling_code`: Look up international country calling codes by free text, ISO code, dial code, or region. Optionally return reviewed, source-linked dialing examples. This tool 
- `normalize_phone_numbers`: Normalize up to 100 records with unique IDs. Invalid records produce individual errors. Optionally identify canonical duplicate candidates; no contacts are chan
- `resolve_phone_region`: Resolve a phone number to metadata-backed country candidates or non-geographic numbering. Results are numbering assignments, not current location or carrier.
