Crear plantillas de un prompt
Crear plantillas de un prompt identificando y extrayendo variables
Las APIs de herramientas de prompts están en una vista previa de investigación cerrada. Solicita unirte a la vista previa de investigación cerrada.
Antes de comenzar
Las herramientas de prompts son un conjunto de APIs para generar y mejorar prompts. A diferencia de nuestras otras APIs, esta es una API experimental: necesitarás solicitar acceso y no tiene el mismo nivel de compromiso de soporte a largo plazo que otras APIs.
Estas APIs son similares a las disponibles en Anthropic Workbench, y están destinadas para su uso por otras plataformas y entornos de ingeniería de prompts.
Comenzando con el mejorador de prompts
Para usar la API de generación de prompts, necesitarás:
- Haberte unido a la vista previa de investigación cerrada para las APIs de herramientas de prompts
- Usar la API directamente, en lugar del SDK
- Agregar el encabezado beta
prompt-tools-2025-04-02
Esta API no está disponible en el SDK

Headers
Optional header to specify the beta version(s) you want to use.
To use multiple betas, use a comma separated list like beta1,beta2 or specify the header multiple times for each beta.
Body
The prompt to templatize, structured as a list of message objects.
Each message in the messages array must:
- Contain only text-only content blocks
- Not include tool calls, images, or prompt caching blocks
Example of a simple text prompt:
[
{
"role": "user",
"content": [
{
"type": "text",
"text": "Translate hello to German"
}
]
}
]
Note that only contiguous user messages with text content are allowed. Assistant prefill is permitted, but other content types will cause validation errors.
The existing system prompt to templatize.
{
"system": "You are a professional English to German translator",
[...]
}
Note that this differs from the Messages API; it is strictly a string.
Response
The templatized prompt with variable placeholders.
The response includes the input messages with specific values replaced by variable placeholders. These messages maintain the original message structure but contain uppercase variable names in place of concrete values.
For example, an input message content like "Translate hello to German" would be transformed to "Translate {{WORD_TO_TRANSLATE}} to {{TARGET_LANGUAGE}}".
{
"messages": [
{
"role": "user",
"content": [
{
"type": "text",
"text": "Translate {{WORD_TO_TRANSLATE}} to {{TARGET_LANGUAGE}}"
}
]
}
]
}
The input system prompt with variables identified and replaced.
If no system prompt was provided in the original request, this field will be an empty string.
Usage information
A mapping of template variable names to their original values, as extracted from the input prompt during templatization. Each key represents a variable name identified in the templatized prompt, and each value contains the corresponding content from the original prompt that was replaced by that variable.
Example:
"variable_values": {
"WORD_TO_TRANSLATE": "hello",
"TARGET_LANGUAGE": "German"
}
In this example response, the original prompt – Translate hello to German – was templatized to Translate WORD_TO_TRANSLATE to TARGET_LANGUAGE, with the variable values extracted as shown.
