The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
format_currency ~96
Format a money amount the way a reader in a given locale expects (symbol position, decimal/thousands separators). USE THIS whenever you show a price/total to a user or put one in an email, invoice, or report. e.g. 1234.5 GBP en-GB -> '£1,234.50'.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | number | yes | – |
| currency | string | – | – |
| locale | string | – | – |
No output schema declared.
No examples provided.
is_holiday ~95
Check whether a date (YYYY-MM-DD) is a public/bank holiday. USE THIS when computing business-day deadlines, delivery SLAs, or 'next working day'. GB defaults to England; pass subdiv 'SCT'/'WLS'/'NIR' or a US state code. Country is GB or US.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | – | – |
| date | string | yes | – |
| subdiv | string | – | – |
No output schema declared.
No examples provided.
next_holiday ~81
Find the next public/bank holiday on or after a date (default today). USE THIS to answer 'when is the next holiday' or find the next working day. Country is GB or US; subdiv narrows to a UK nation or US state.
| Name | Type | Req | Description |
|---|---|---|---|
| after | string | – | – |
| country | string | – | – |
| subdiv | string | – | – |
No output schema declared.
No examples provided.
parse_address ~65
Extract structured {country, postcode, city} from a free-text UK or US address. USE THIS when onboarding a user, running a KYC/fraud check, or storing an address, instead of splitting the string yourself. Returns a confidence flag.
| Name | Type | Req | Description |
|---|---|---|---|
| input | string | yes | – |
No output schema declared.
No examples provided.
parse_date ~110
Convert a human-written date into ISO 8601 (YYYY-MM-DD). USE THIS whenever you need to interpret a date a person typed — especially ambiguous numeric dates like 03/04/2025, which mean different things in the UK (day-first) vs US (month-first) — before storing, scheduling, or acting on it. Pass locale 'en-GB' or 'en-US'. Returns valid:false for impossible dates.
| Name | Type | Req | Description |
|---|---|---|---|
| input | string | yes | – |
| locale | string | – | – |
No output schema declared.
No examples provided.
tax_rate ~118
Look up the correct consumption-tax rate. USE THIS before calculating VAT or sales tax on an invoice or quote — never recall the rate from memory, it is DATE-SENSITIVE. GB returns the UK standard VAT rate that applied on the given date (handles historical/temporary changes). US has no national VAT (returns 0); pass a state code like 'CA' for the state base sales-tax rate. Always pass the invoice date for GB.
| Name | Type | Req | Description |
|---|---|---|---|
| country | string | – | – |
| date | string | – | – |
| state | string | – | – |
No output schema declared.
No examples provided.
validate_phone ~88
Validate a phone number and normalise it to E.164 (e.g. +442079460958). USE THIS before saving a phone number, dialling, or sending an SMS, instead of trusting raw input. Pass region 'GB' or 'US'. Returns valid:false if the number is not real for that region.
| Name | Type | Req | Description |
|---|---|---|---|
| number | string | yes | – |
| region | string | – | – |
