# Delete Tool

`DELETE /tool/{id}`

## Path parameters

- `id` string, uuid, required

## Response `200`

- union
  - ApiRequestTool
    - `latestVersion` string, nullable

        - ToolMessageStart
          - `contents` TextContent[] — This is an alternative to the `content` property. It allows to specify variants of the same content, one per language. Usage: - If your assistants are multilingual, you can provide content for each language. - If you don't provide content for a language, the first item in the array will be automatically translated to the active language at that moment. This will override the `content` property.

          - `role` 'assistant' | 'system' — This is optional and defaults to "assistant". When role=assistant, `content` is said out loud. When role=system, `content` is passed to the model in a system message.

It's an exclusive OR.
          - `role` 'assistant' | 'system' — This is optional and defaults to "assistant". When role=assistant, `content` is said out loud when the tool call fails. When role=system, `content` is passed to the model as a system message along with the failure result, and the model's generated response is spoken. Example: assistant: tool called tool: error from your server <--- system prompt as hint ---> model generates response which is spoken This is useful when you want the model to generate an error-aware response instead of speaking a fixed failure message.
          - `endCallAfterSpokenEnabled` boolean — This is an optional boolean that if true, the call will end after the message is spoken. Default is false. This is ignored if `role` is set to `system`. @default false

            - `type` 'regex', required — This is the type discriminator for regex condition
            - `regex` string, required — This is the regular expression pattern to match against message content. Note: - This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true. Hot tips: - In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline

To access these variables, you can reference them as `{{customerName}}`, `{{fullName}}`, `{{greeting}}`, `{{customerCity}}`, and `{{something}}`.
        - `key` string, required — This is the key of the variable. This variable will be accessible during the call as `{{key}}` and stored in `call.artifact.variableValues` after the call.

It's an exclusive OR.
          - `role` 'assistant' | 'system' — This is optional and defaults to "assistant". When role=assistant, `content` is said out loud when the tool call fails. When role=system, `content` is passed to the model as a system message along with the failure result, and the model's generated response is spoken. Example: assistant: tool called tool: error from your server <--- system prompt as hint ---> model generates response which is spoken This is useful when you want the model to generate an error-aware response instead of speaking a fixed failure message.

            - `param` string, required — This is the name of the parameter that you want to check.
            - `value` string, required — This is the value you want to compare against the parameter.
    - `type` 'code', required — The type of tool. "code" for Code tool.
    - `async` boolean — This determines if the tool is async. If async, the assistant will move forward without waiting for your server to respond.

They allow you to define nested structures. For `array`, you can define the schema of the items in the array using the `items` property. For `object`, you can define the properties of the object using the `properties` property.
        - `items` JsonSchema — recursive
        - `properties` object — This is required if the type is "object". This specifies the properties of the object. This is a map of property names to JsonSchema objects.
        - `description` string — This is the description to help the model understand what it needs to output.
        - `pattern` string — This is the pattern of the string. This is a regex that will be used to validate the data in question. To use a common format, use the `format` property instead. OpenAI documentation: https://platform.openai.com/docs/guides/structured-outputs#supported-properties
        - `format` 'date-time' | 'time' | 'date' | 'duration' | 'email' | 'hostname' | 'ipv4' | 'ipv6' | 'uuid' — This is the format of the string.

        - `title` string — This is the title of the schema.
      - `aliases` VariableExtractionAlias[] — These are additional variables to create. These will be accessible during the call as `{{key}}` and stored in `call.artifact.variableValues` after the call. Example: ```json { "aliases": [ { "key": "customerName", "value": "{{name}}" }, { "key": "fullName", "value": "{{firstName}} {{lastName}}" }, { "key": "greeting", "value": "Hello {{name}}, welcome to {{company}}!" }, { "key": "customerCity", "value": "{{addresses[0].city}}" }, { "key": "something", "value": "{{any liquid}}" } ] } ``` This will create variables `customerName`, `fullName`, `greeting`, `customerCity`, and `something`. To access these variables, you can reference them as `{{customerName}}`, `{{fullName}}`, `{{greeting}}`, `{{customerCity}}`, and `{{something}}`.
        - `key` string, required — This is the key of the variable. This variable will be accessible during the call as `{{key}}` and stored in `call.artifact.variableValues` after the call. Rules: - Must start with a letter (a-z, A-Z). - Subsequent characters can be letters, numbers, or underscores. - Minimum length of 1 and maximum length of 40.
        - `value` string, required — This is the value of the variable. This can reference existing variables, use filters, and perform transformations. Examples: "{{name}}", "{{customer.email}}", "Hello {{name | upcase}}"

    - `updatedAt` string, date-time, required — This is the ISO 8601 date-time string of when the tool was last updated.
    - `rejectionPlan` ToolRejectionPlan
      - `conditions` union[] — This is the list of conditions that must be evaluated. Usage: - If all conditions match (AND logic), the tool call is rejected. - For OR logic at the top level, use a single 'group' condition with operator: 'OR'. @default [] - Empty array means tool always executes
        - union
          - RegexCondition
            - `type` 'regex', required — This is the type discriminator for regex condition
            - `regex` string, required — This is the regular expression pattern to match against message content. Note: - This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true. Hot tips: - In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline

When role=system, `content` is passed to the model as a system message along with the failure result, and the model's generated response is spoken. Example: assistant: tool called tool: error from your server <--- system prompt as hint ---> model generates response which is spoken This is useful when you want the model to generate an error-aware response instead of speaking a fixed failure message.

When role=system, `content` is passed to the model as a system message along with the failure result, and the model's generated response is spoken. Example: assistant: tool called tool: error from your server <--- system prompt as hint ---> model generates response which is spoken This is useful when you want the model to generate an error-aware response instead of speaking a fixed failure message.

            - `type` 'regex', required — This is the type discriminator for regex condition
            - `regex` string, required — This is the regular expression pattern to match against message content. Note: - This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true. Hot tips: - In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline

          - `type` 'request-complete', required — This message is triggered when the tool call is complete. This message is triggered immediately without waiting for your server to respond for async tool calls. If this message is not provided, the model will be requested to respond. If this message is provided, only this message will be spoken and the model will not be requested to come up with a response. It's an exclusive OR.
          - `role` 'assistant' | 'system' — This is optional and defaults to "assistant". When role=assistant, `content` is said out loud. When role=system, `content` is passed to the model in a system message. Example: system: default one assistant: user: assistant: user: assistant: user: assistant: tool called tool: your server response <--- system prompt as hint ---> model generates response which is spoken This is useful when you want to provide a hint to the model about what to say next.
          - `endCallAfterSpokenEnabled` boolean — This is an optional boolean that if true, the call will end after the message is spoken. Default is false. This is ignored if `role` is set to `system`. @default false
          - `content` string — This is the content that the assistant says when this message is triggered.
          - `conditions` Condition[] — This is an optional array of conditions that the tool call arguments must meet in order for this message to be triggered.

        - ToolMessageFailed
          - `contents` TextContent[] — This is an alternative to the `content` property. It allows to specify variants of the same content, one per language. Usage: - If your assistants are multilingual, you can provide content for each language. - If you don't provide content for a language, the first item in the array will be automatically translated to the active language at that moment. This will override the `content` property.

          - `type` 'request-failed', required — This message is triggered when the tool call fails. This message is never triggered for async tool calls. If this message is not provided, the model will be requested to respond. If this message is provided, only this message will be spoken and the model will not be requested to come up with a response. It's an exclusive OR.
          - `role` 'assistant' | 'system' — This is optional and defaults to "assistant". When role=assistant, `content` is said out loud when the tool call fails. When role=system, `content` is passed to the model as a system message along with the failure result, and the model's generated response is spoken. Example: assistant: tool called tool: error from your server <--- system prompt as hint ---> model generates response which is spoken This is useful when you want the model to generate an error-aware response instead of speaking a fixed failure message.
          - `endCallAfterSpokenEnabled` boolean — This is an optional boolean that if true, the call will end after the message is spoken. Default is false. This is ignored if `role` is set to `system`. @default false

            - `param` string, required — This is the name of the parameter that you want to check.
            - `value` string, required — This is the value you want to compare against the parameter.
    - `type` 'function', required — The type of tool. "function" for Function tool.
    - `async` boolean — This determines if the tool is async. If async, the assistant will move forward without waiting for your server to respond. This is useful if you just want to trigger something on your server. If sync, the assistant will wait for your server to respond. This is useful if want assistant to respond with the result from your server. Defaults to synchronous (`false`).

This is an anti-pattern and should be avoided outside of edge case scenarios.
      - `backoffPlan` BackoffPlan
        - `type` object, required — This is the type of backoff plan to use. Defaults to fixed. @default fixed

Example: ```json { "aliases": [ { "key": "customerName", "value": "{{name}}" }, { "key": "fullName", "value": "{{firstName}} {{lastName}}" }, { "key": "greeting", "value": "Hello {{name}}, welcome to {{company}}!" }, { "key": "customerCity", "value": "{{addresses[0].city}}" }, { "key": "something", "value": "{{any liquid}}" } ] } ``` This will create variables `customerName`, `fullName`, `greeting`, `customerCity`, and `something`. To access these variables, you can reference them as `{{customerName}}`, `{{fullName}}`, `{{greeting}}`, `{{customerCity}}`, and `{{something}}`.
        - `key` string, required — This is the key of the variable. This variable will be accessible during the call as `{{key}}` and stored in `call.artifact.variableValues` after the call.

          - RegexCondition
            - `type` 'regex', required — This is the type discriminator for regex condition
            - `regex` string, required — This is the regular expression pattern to match against message content. Note: - This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true. Hot tips: - In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline
            - `target` MessageTarget
              - …
            - `negate` boolean — This is the flag that when true, the condition matches if the pattern does NOT match. Useful for ensuring certain words/phrases are absent. @default false

            - `liquid` string, required — This is the Liquid template that must return exactly "true" or "false" as a string. The template is evaluated and the entire output must be either "true" or "false" - nothing else. Available variables: - `messages`: Array of recent messages in OpenAI chat completions format (ChatCompletionMessageParam[]) Each message has properties like: role ('user', 'assistant', 'system'), content (string), etc. - `now`: Current timestamp in milliseconds (built-in Liquid variable) - Any assistant variable values (e.g., `userName`, `accountStatus`) Useful Liquid filters for messages: - `messages | last: 5` - Get the 5 most recent messages - `messages | where: 'role', 'user'` - Filter to only user messages - `messages | reverse` - Reverse the order of messages
          - GroupCondition
            - `type` 'group', required — This is the type discriminator for group condition
            - `operator` 'AND' | 'OR', required — This is the logical operator for combining conditions in this group

          - RegexCondition
            - `type` 'regex', required — This is the type discriminator for regex condition
            - `regex` string, required — This is the regular expression pattern to match against message content. Note: - This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true. Hot tips: - In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline
            - `target` MessageTarget
              - …
            - `negate` boolean — This is the flag that when true, the condition matches if the pattern does NOT match. Useful for ensuring certain words/phrases are absent. @default false

          - RegexCondition
            - `type` 'regex', required — This is the type discriminator for regex condition
            - `regex` string, required — This is the regular expression pattern to match against message content. Note: - This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true. Hot tips: - In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline
            - `target` MessageTarget
              - …
            - `negate` boolean — This is the flag that when true, the condition matches if the pattern does NOT match. Useful for ensuring certain words/phrases are absent. @default false

Usage: - If this is not provided and transfer tool messages is not provided, default is "Transferring the call now". - If set to "", nothing is spoken. This is useful when you want to silently transfer. This is especially useful when transferring between assistants in a squad. In this scenario, you likely also want to set `assistant.firstMessageMode=assistant-speaks-first-with-model-generated-message` for the destination assistant.

Defaults to `rolling-history`. - `rolling-history`: This is the default mode. It keeps the entire conversation history and appends the new assistant's system message on transfer. Example: Pre-transfer: system: assistant1 system message assistant: assistant1 first message user: hey, good morning assistant: how can i help? user: i need help with my account assistant: (destination.message) Post-transfer: system: assistant1 system message assistant: assistant1 first message user: hey, good morning assistant: how can i help? user: i need help with my account assistant: (destination.message) system: assistant2 system message assistant: assistant2 first message (or model generated if firstMessageMode is set to `assistant-speaks-first-with-model-generated-message`) - `swap-system-message-in-history`: This replaces the original system message with the new assistant's system message on transfer. Example: Pre-transfer: system: assistant1 system message assistant: assistant1 first message user: hey, good morning assistant: how can i help? user: i need help with my account assistant: (destination.message) Post-transfer: system: assistant2 system message assistant: assistant1 first message user: hey, good morning assistant: how can i help? user: i need help with my account assistant: (destination.message) assistant: assistant2 first message (or model generated if firstMessageMode is set to `assistant-speaks-first-with-model-generated-message`) - `delete-history`: This deletes the entire conversation history on transfer.

          - `assistantName` string, required — This is the assistant to transfer the call to.
          - `name` string — This is the name of the transfer destination. This is just for your own reference. Usage: - Optional. Stored with the destination wherever it is supplied. For `number` and `sip` destinations it is also persisted on the transfer record in the call artifact after a transfer and displayed in the dashboard call log (on the transfer divider in the transcript view) alongside the destination. When omitted, everything behaves exactly as before. - Display-only. Unlike `description`, it is never included in prompts or tool descriptions and has no effect on model behavior or destination choice.

          - `numberE164CheckEnabled` boolean — This is the flag to toggle the E164 check for the `number` field. This is an advanced property which should be used if you know your use case requires it. Use cases: - `false`: To allow non-E164 numbers like `+001234567890`, `1234`, or `abc`. This is useful for dialing out to non-E164 numbers on your SIP trunks. - `true` (default): To allow only E164 numbers like `+14155551234`. This is standard for PSTN calls. If `false`, the `number` is still required to only contain alphanumeric characters (regex: `/^\+?[a-zA-Z0-9]+$/`). @default true (E164 check is enabled)
          - `number` string, required — This is the phone number to transfer the call to.
          - `extension` string — This is the extension to dial after transferring the call to the `number`.
          - `callerId` string — This is the caller ID to use when transferring the call to the `number`. Usage: - If not provided, the caller ID will be the number the call is coming **from**. Example: a customer with number +14151111111 calls in to and the assistant transfers out to +16470000000. +16470000000 will see +14151111111 as the caller. For inbound calls, the caller ID is the customer's number. For outbound calls, the caller ID is the phone number of the assistant. - To change this behavior, provide a `callerId`. - Set to '{{customer.number}}' to always use the customer's number as the caller ID. - Set to '{{phoneNumber.number}}' to always use the phone number of the assistant as the caller ID. - Set to any E164 number to always use that number as the caller ID. This needs to be a number that is owned or verified by your Transport provider like Twilio. For Twilio, you can read up more here: https://www.twilio.com/docs/voice/twiml/dial#callerid

When you're using handoff tool, we recommend adding this to your system prompt --- # System context You are part of a multi-agent system designed to make agent coordination and execution easy. Agents uses two primary abstraction: **Agents** and **Handoffs**. An agent encompasses instructions and tools and can hand off a conversation to another agent when appropriate. Handoffs are achieved by calling a handoff function, generally named `handoff_to_<agent_name>`. Handoffs between agents are handled seamlessly in the background; do not mention or draw attention to these handoffs in your conversation with the user. # Agent context {put your agent system prompt here} ---
    - `defaultResult` string — This is the default local tool result message used when no runtime handoff result override is returned.
    - `destinations` union[] — These are the destinations that the call can be handed off to. Usage: 1.

Dynamic destination 3.1 To determine the destination dynamically, supply a `dynamic` handoff destination type and a `server` object. VAPI will send a handoff-destination-request webhook to the `server.url`. The response from the server will be used as the destination (if valid). ```json { "tools": [ { "type": "handoff", "destinations": [ { "type": "dynamic", "server": { "url": "https://example.com" } } ], } ] } ``` 3.2. To pass custom parameters to the server, you can use the `function` object. ```json { "tools": [ { "type": "handoff", "destinations": [ { "type": "dynamic", "server": { "url": "https://example.com" }, } ], "function": { "name": "handoff", "description": "Call this function when the customer is ready to be handed off to the next assistant", "parameters": { "type": "object", "properties": { "destination": { "type": "string", "description": "Use dynamic when customer is ready to be handed off to the next assistant", "enum": ["dynamic"] }, "customerAreaCode": { "type": "number", "description": "Area code of the customer" }, "customerIntent": { "type": "string", "enum": ["new-customer", "existing-customer"], "description": "Use new-customer when customer is a new customer, existing-customer when customer is an existing customer" }, "customerSentiment": { "type": "string", "enum": ["positive", "negative", "neutral"], "description": "Use positive when customer is happy, negative when customer is unhappy, neutral when customer is neutral" } } } } } ] } ``` The properties `customerAreaCode`, `customerIntent`, and `customerSentiment` will be passed to the server in the webhook request body.

Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline

            - `type` 'regex', required — This is the type discriminator for regex condition
            - `regex` string, required — This is the regular expression pattern to match against message content. Note: - This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true. Hot tips: - In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline

This is an anti-pattern and should be avoided outside of edge case scenarios.
      - `backoffPlan` BackoffPlan
        - `type` object, required — This is the type of backoff plan to use. Defaults to fixed. @default fixed
        - `maxRetries` number, required — This is the maximum number of retries to attempt if the request fails. Defaults to 0 (no retries). @default 0

            - `type` 'regex', required — This is the type discriminator for regex condition
            - `regex` string, required — This is the regular expression pattern to match against message content. Note: - This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true. Hot tips: - In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline

      - `url` string — This is where the request will be sent.
      - `headers` object — These are the headers to include in the request. Each key-value pair represents a header name and its value. Note: Specifying an Authorization header here will override the authorization provided by the `credentialId` (if provided). This is an anti-pattern and should be avoided outside of edge case scenarios.
      - `backoffPlan` BackoffPlan
        - `type` object, required — This is the type of backoff plan to use. Defaults to fixed. @default fixed
        - `maxRetries` number, required — This is the maximum number of retries to attempt if the request fails. Defaults to 0 (no retries). @default 0
        - `baseDelaySeconds` number, required — This is the base delay in seconds. For linear backoff, this is the delay between each retry. For exponential backoff, this is the initial delay.
        - `excludedStatusCodes` object[] — This is the excluded status codes. If the response status code is in this list, the request will not be retried. By default, the request will be retried for any non-2xx status code.

            - `type` 'regex', required — This is the type discriminator for regex condition
            - `regex` string, required — This is the regular expression pattern to match against message content. Note: - This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true. Hot tips: - In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline

Available variables: - `messages`: Array of recent messages in OpenAI chat completions format (ChatCompletionMessageParam[]) Each message has properties like: role ('user', 'assistant', 'system'), content (string), etc. - `now`: Current timestamp in milliseconds (built-in Liquid variable) - Any assistant variable values (e.g., `userName`, `accountStatus`) Useful Liquid filters for messages: - `messages | last: 5` - Get the 5 most recent messages - `messages | where: 'role', 'user'` - Filter to only user messages - `messages | reverse` - Reverse the order of messages
          - GroupCondition
            - `type` 'group', required — This is the type discriminator for group condition

Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline

            - `type` 'regex', required — This is the type discriminator for regex condition
            - `regex` string, required — This is the regular expression pattern to match against message content. Note: - This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true. Hot tips: - In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline

It's an exclusive OR.
          - `role` 'assistant' | 'system' — This is optional and defaults to "assistant". When role=assistant, `content` is said out loud when the tool call fails.

          - RegexCondition
            - `type` 'regex', required — This is the type discriminator for regex condition
            - `regex` string, required — This is the regular expression pattern to match against message content. Note: - This works by using the RegExp.test method in Node.JS. Eg. /hello/.test("hello there") will return true. Hot tips: - In JavaScript, escape \ when sending the regex pattern. Eg. "hello\sthere" will be sent over the wire as "hellosthere". Send "hello\\sthere" instead. - RegExp.test does substring matching, so /cat/.test("I love cats") will return true. To do full string matching, use anchors: /^cat$/ will only match exactly "cat". - Word boundaries \b are useful for matching whole words: /\bcat\b/ matches "cat" but not "cats" or "category". - Use inline flags for portability: (?i) for case insensitive, (?m) for multiline
