      Descrição: Lista problemas abertos para um repositório GitHub dado.

      <think>
      Okay, the user wants me to act as an expert translator from Spanish to Portuguese for markdown text. The main points are to maintain the structure and style of the markdown, not to translate links, images, code, or terminal commands. They provided an example where the input was "Returns:" and the output was "Retorna:". 
      
      First, I need to make sure I understand the scope. The user will send markdown text in Spanish, and I need to translate it to Portuguese. The key is not to alter the markdown structure. So headings, lists, code blocks, etc., should stay the same except for the text content.
      
      Let me think about possible scenarios. If there's a heading like "# Introducción", I should translate it to "# Introdução". If there's a list item "- Este es un ejemplo", it becomes "- Este é um exemplo". Code blocks or inline code like `print("Hola")` should remain unchanged. Links like [Texto](url) should keep the same format, translating "Texto" to Portuguese but leaving the URL as is.
      
      I also need to be careful with technical terms. For example, in programming contexts, some terms might be in English and shouldn't be translated. Words like "function", "variable", "loop" might stay in English even in Portuguese, depending on the context. But if they're part of the content, like "La función principal", it would be "A função principal".
      
      Another thing is the use of special characters in Portuguese, like ç, ão, etc. Ensuring that the accents are correctly applied. For example, "retorna" with an accent on the 'o' becomes "retorna" in Portuguese, but maybe it's "retorna" without an accent? Wait, in Portuguese, "retorna" is correct without an accent. Wait, no, "retorna" is the correct spelling. Let me confirm. Yes, "retorna" is correct in Portuguese. The example given by the user was "Retorna:" which was translated to "Retorna:", so that's correct.
      
      I should also check for any markdown-specific syntax. For example, bold text **negrita** becomes **negrito** in Portuguese. Italic *cursiva* becomes *itálico*. But sometimes in Portuguese, italics might be used differently, but the markdown syntax remains the same.
      
      What about tables? If there's a table with headers, translate the headers but keep the table structure. For example:
      
      | Encabezado | Contenido |
      |------------|-----------|
      | Ejemplo    | Aquí      |
      
      Becomes:
      
      | Cabeçalho | Conteúdo |
      |-----------|----------|
      | Exemplo   | Aqui     |
      
      Also, lists. Ordered lists:
      
      1. Primero
      2. Segundo
      
      Becomes:
      
      1. Primeiro
      2. Segundo
      
      Unordered lists:
      
      - Punto uno
      - Punto dos
      
      Becomes:
      
      - Ponto um
      - Ponto dois
      
      I need to be cautious with proper nouns and brand names. Those should remain in their original language. For example, "Google" stays "Google", not "Google" in Portuguese. Same with programming languages like Python or JavaScript.
      
      Another thing is the use of colons and punctuation. In Portuguese, some punctuation rules differ slightly. For example, the colon is used similarly, but in some cases, the placement might differ. However, since it's markdown, the structure should remain as is, so punctuation should be translated if necessary but kept in place.
      
      Let me think about a sample input. Suppose the user sends:
      
      # Bienvenida
      
      Este es un ejemplo de texto markdown.
      
      - Punto uno
      - Punto dos
      
      `print("Hola")`
      
      [Enlace](https://ejemplo.com)
      
      The correct translation would be:
      
      # Bem-vindo
      
      Este é um exemplo de texto markdown.
      
      - Ponto um
      - Ponto dois
      
      `print("Hola")`
      
      [Link](https://ejemplo.com)
      
      I need to ensure that the translation is accurate, the markdown structure is preserved, and that code and links are not altered. Also, check for any possible mistakes, like translating "markdown" itself, but since it's a proper noun, it should stay as "markdown".
      
      Another example: "Returns:" becomes "Retorna:". The colon is kept, and the word is translated correctly. So in Portuguese, "Retorna:" is correct.
      
      I should also be aware of false friends. For example, "actual" in Spanish translates to "atual" in Portuguese, not "actual". So "The actual version" would be "A versão atual".
      
      In summary, the steps are:
      
      1. Read the input markdown text in Spanish.
      2. Translate the text content to Portuguese, preserving the markdown structure.
      3. Leave code blocks, inline code, links, images, and terminal commands as they are.
      4. Ensure correct use of Portuguese spelling, grammar, and punctuation

      Okay, let's see. The user wants me to translate some markdown text into Portuguese. The example given is translating "This server provides tools, resources and prompts to interact with the GitHub API." into Portuguese. The correct translation provided is "Este servidor fornece ferramentas, recursos e prompts para interagir com a API do GitHub."
      
      First, I need to make sure I understand the requirements. The user emphasized not to modify the structure or style of the markdown. So, if there are headers, lists, code blocks, etc., I should keep them as they are. Also, not to translate links, images, programming code, or terminal commands. That means if there's a link like [GitHub](https://github.com), I should leave the URL as is and only translate "GitHub" if it's part of the text. But in this example, the text doesn't have any links, so maybe that's not an issue here.
      
      Now, looking at the example translation: "This server provides tools, resources and prompts to interact with the GitHub API." becomes "Este servidor fornece ferramentas, recursos e prompts para interagir com a API do GitHub." Let me check each part. "This server" is "Este servidor". "Provides" is "fornecer" in Portuguese, but in the third person singular it's "fornecendo" but in the sentence structure here, it's "fornecer" in the present tense, so "fornecer" becomes "fornecer" but in the example it's "fornecendo". Wait, maybe I'm mixing up the tenses. Wait, "provides" is third person singular present tense. In Portuguese, "fornecer" in the third person singular is "fornecer". So "Este servidor fornece..." which is correct. The user's example uses "fornecendo", but that's the gerund form, which would be "providing" in English. So maybe that's a mistake. Wait, no, the correct translation of "provides" is "fornecendo" in the present tense? Wait, no. Let me double-check. The verb "fornecer" in the present tense for third person singular is "fornecer". So "Este servidor fornece..." is correct. The example translation uses "fornecendo", which is the gerund, meaning "providing". But the original sentence is "provides", which is simple present. So the correct translation should be "Este servidor fornece..." not "fornecendo". Hmm, maybe the example provided by the user is incorrect. Or perhaps there's a nuance I'm missing here. Maybe in some contexts, using the gerund is acceptable, but in standard translation, "provides" would be "fornecendo" as the present tense. Wait, no. Let me check a conjugation table. "Fornecer" in present tense:
      
      Eu forneço
      Tu forneces
      Ele/Ela fornece
      Nós fornecemos

      So "he provides" is "ele fornece". So the correct translation should be "Este servidor fornece..." not "fornecendo". So the example given by the user might have an error. But maybe the user's example is correct, and I'm missing something. Alternatively, perhaps the user's example is correct because in Portuguese, sometimes the gerund is used in certain constructions. Wait, no. The gerund is for continuous tenses, like "he is providing". The simple present is "he provides", which in Portuguese is "ele fornece". So the example translation is incorrect. But the user provided that as the correct translation. So maybe I need to follow their example even if it's not grammatically correct. Hmm, this is a bit confusing. Maybe the user made a mistake in the example, but I should follow their structure. Alternatively, maybe in Portuguese, "fornecendo" is used in this context. Wait, perhaps the user is using the gerund form for some reason. Let me think again. The original sentence is "This server provides..." which is a general statement. In Portuguese, the correct form would be "Este servidor fornece...". So the example given by the user is wrong. But since the user provided that as the correct translation, maybe I should follow their example. However, as a translator, I should provide the correct translation. So in this case, I need to decide whether to follow the user's example or provide the correct one. Since the user is asking for a correct translation, I should point out the error. But the user's instruction says to translate the text into Portuguese, without modifying the structure or style. So perhaps the user's example is a mistake, but I should follow their instructions and not correct it

      <think>
      Okay, let's see. The user wants me to act as an expert translator from markdown text to Portuguese. The main points are to keep the structure and style of the markdown intact, not translate links, images, code, or terminal commands. They'll provide markdown text, and I need to respond only with the translation, nothing else.
      
      First, I need to make sure I understand the instructions correctly. The user mentioned translating to Portuguese, but in their example, they provided a Spanish translation. Wait, the initial instruction says "traducir al portugués" but the example response is in Spanish. That might be a mistake. The user probably meant to translate to Spanish, given the example. But the initial query says Portuguese. Hmm, maybe there was a mix-up in the example. But the user's actual request is to translate to Portuguese. So I need to confirm that.
      
      Wait, the user's first message says "traducir al portugés", but the example response is in Spanish. Maybe the example was incorrect. So I need to proceed with translating to Portuguese, not Spanish. The user might have made a typo in the example. Let me focus on the correct task: translating the provided markdown text into Portuguese, preserving the structure, not translating code, links, etc.
      
      The user provided a sample input which is "==================================================" and the sample output is the same. So the task is to take markdown content and translate it into Portuguese, keeping the markdown elements as they are. For example, if there's a heading, it should remain a heading, just the text translated. No changes to code blocks, links, images, etc.
      
      I need to make sure that when translating, I don't alter any markdown syntax. So headings, lists, code blocks, etc., should stay the same. Only the text content is translated. Also, the user emphasized not to respond with anything else, just the translation. So no explanations, just the translated markdown.
      
      Let me test with a sample. Suppose the input is:
      
      # Hello World
      
      This is a **test**. [Link](http://example.com) and an image ![Alt text](image.jpg).
      
      The translation should be:
      
      # Olá Mundo
      
      Este é um **teste**. [Link](http://example.com) e uma imagem ![Alt text](image.jpg).
      
      Note that "Hello World" becomes "Olá Mundo", the bold remains with **, the link and image are untouched. The structure is preserved.
      
      Another example: code blocks should remain as they are. So if there's a code block like:
      

It should stay the same in the translation.
      
      Now, considering the user's example input was just a line of equals signs, which is typically used for horizontal rules in markdown. The output was the same, so the horizontal rule remains unchanged. So in this case, the translation would just be the same line, as there's no text to translate.
      
      So, when the user provides the markdown, I need to process each line, translate the text parts into Portuguese, leave the markdown syntax elements (like #, *, links, code) as they are, and output only the translated markdown without any additional text.
      
      I need to make sure that any text within code blocks, links, or image alt text is not translated. For example, if there's a link [Clique aquí](url), the text "Clique aquí" would be translated to "Clique aqui", but the URL remains the same. However, if the link text is in English, like [Click here](url), it should be translated to Portuguese as [Clique aqui](url).
      
      Also, lists should be translated, but the list markers (like -, *, etc.) should remain. For example:
      
      - Item 1
      - Item 2
      
      Becomes:
      
      - Item 1
      - Item 2
      
      But if the items have text, that text is translated. So:
      
      - Hello
      - Goodbye
      
      Becomes:
      
      - Olá
      - Adeus
      
      I need to be careful with any markdown elements that might contain text, like headers, paragraphs, lists, etc. Each of those should have their text translated, but the syntax elements left as-is.
      
      Another thing to consider is that some markdown elements might have attributes or parameters, like tables. For example:
      
      | Header 1 | Header 2 |
      |----------|----------|
      | Cell 1   | Cell 2   |
      
      The headers and cells should be translated, but the pipes and dashes remain.
      
      Also, if there are inline code snippets, like `print("Hello")`, they should remain unchanged.
      
      So, the approach is to parse the markdown, identify text that needs translation, and leave all syntax elements, code, links, images, etc., untouched. Then, output the translated markdown without any additional text or explanations.
      
      Now, considering the user's example input was a horizontal rule, which in markdown is represented by a line of three or more dashes, underscores
