+## نظرة عامة
+
+يمكن توسيع وكلاء CrewAI بـ **خمسة أنواع مميزة من القدرات**، كل منها يخدم غرضًا مختلفًا. فهم متى تستخدم كل نوع — وكيف يعملون معًا — هو المفتاح لبناء وكلاء فعّالين.
+

+

+
+## التمييز الأساسي
+
+أهم شيء يجب فهمه: **هذه القدرات تنقسم إلى فئتين**.
+
+### قدرات الإجراء (الأدوات، MCP، التطبيقات)
+
+تمنح الوكلاء القدرة على **فعل أشياء** — استدعاء APIs، قراءة الملفات، البحث على الويب، إرسال رسائل البريد الإلكتروني. عند التنفيذ، تتحول الأنواع الثلاثة إلى نفس التنسيق الداخلي (مثيلات `BaseTool`) وتظهر في قائمة أدوات موحدة يمكن للوكيل استدعاؤها.
+
+```python
+from crewai import Agent
+from crewai_tools import SerperDevTool, FileReadTool
+
+agent = Agent(
+    role="Researcher",
+    goal="Find and compile market data",
+    backstory="Expert market analyst",
+    tools=[SerperDevTool(), FileReadTool()],  # أدوات محلية
+    mcps=["https://mcp.example.com/sse"],     # أدوات خادم MCP عن بُعد
+    apps=["gmail", "google_sheets"],           # تكاملات المنصة
+)
+```
+
+### قدرات السياق (المهارات، المعرفة)
+
+تُعدّل **إرشادات** الوكيل — بحقن الخبرة أو التعليمات أو البيانات المُسترجعة قبل أن يبدأ الوكيل في التفكير. لا تمنح الوكلاء إجراءات جديدة؛ بل تُشكّل كيف يفكر الوكلاء وما هي المعلومات التي يمكنهم الوصول إليها.
+
+```python
+from crewai import Agent
+
+agent = Agent(
+    role="Security Auditor",
+    goal="Audit cloud infrastructure for vulnerabilities",
+    backstory="Expert in cloud security with 10 years of experience",
+    skills=["./skills/security-audit"],        # تعليمات المجال
+    knowledge_sources=[pdf_source, url_source], # حقائق مُسترجعة
+)
+```
+

+
+## متى تستخدم ماذا
+
+| تحتاج إلى...                                            | استخدم            | مثال                                     |
+| :------------------------------------------------------- | :---------------- | :--------------------------------------- |
+| الوكيل يبحث على الويب                                    | **الأدوات**       | `tools=[SerperDevTool()]`                |
+| الوكيل يستدعي API عن بُعد عبر MCP                        | **MCP**           | `mcps=["https://api.example.com/sse"]`   |
+| الوكيل يرسل بريد إلكتروني عبر Gmail                      | **التطبيقات**     | `apps=["gmail"]`                         |
+| الوكيل يتبع إجراءات محددة                                | **المهارات**      | `skills=["./skills/code-review"]`        |
+| الوكيل يرجع لمستندات الشركة                              | **المعرفة**       | `knowledge_sources=[pdf_source]`         |
+| الوكيل يبحث على الويب ويتبع إرشادات المراجعة              | **الأدوات + المهارات** | استخدم كليهما معًا                  |
+

+
+## دمج القدرات
+
+في الممارسة العملية، غالبًا ما يستخدم الوكلاء **أنواعًا متعددة من القدرات معًا**. إليك مثال واقعي:
+
+```python
+from crewai import Agent
+from crewai_tools import SerperDevTool, FileReadTool, CodeInterpreterTool
+
+# وكيل بحث مجهز بالكامل
+researcher = Agent(
+    role="Senior Research Analyst",
+    goal="Produce comprehensive market analysis reports",
+    backstory="Expert analyst with deep industry knowledge",
+
+    # الإجراء: ما يمكن للوكيل فعله
+    tools=[
+        SerperDevTool(),         # البحث على الويب
+        FileReadTool(),          # قراءة الملفات المحلية
+        CodeInterpreterTool(),   # تشغيل كود Python للتحليل
+    ],
+    mcps=["https://data-api.example.com/sse"],  # الوصول لـ API بيانات عن بُعد
+    apps=["google_sheets"],                      # الكتابة في Google Sheets
+
+    # السياق: ما يعرفه الوكيل
+    skills=["./skills/research-methodology"],    # كيفية إجراء البحث
+    knowledge_sources=[company_docs],            # بيانات خاصة بالشركة
+)
+```
+

+المهارات هي مجلدات مستقلة توفر للوكلاء **تعليمات وإرشادات ومواد مرجعية خاصة بالمجال**. تُعرّف كل مهارة بملف `SKILL.md` يحتوي على بيانات وصفية YAML ومحتوى Markdown.
 
-تستخدم المهارات **الكشف التدريجي** — يتم تحميل البيانات الوصفية أولاً، ثم التعليمات الكاملة فقط عند التفعيل، وكتالوجات الموارد فقط عند الحاجة.
+عند التفعيل، يتم حقن تعليمات المهارة مباشرة في إرشادات مهمة الوكيل — مما يمنح الوكيل خبرة دون الحاجة لأي تغييرات في الكود.
+
+<Note type="info" title="المهارات مقابل الأدوات — التمييز الأساسي">
+**المهارات ليست أدوات.** هذه هي نقطة الارتباك الأكثر شيوعًا.
+
+- **المهارات** تحقن *تعليمات وسياق* في إرشادات الوكيل. تخبر الوكيل *كيف يفكر* في مشكلة ما.
+- **الأدوات** تمنح الوكيل *دوال قابلة للاستدعاء* لاتخاذ إجراءات (البحث، قراءة الملفات، استدعاء APIs).
+
+غالبًا ما تحتاج **كليهما**: مهارات للخبرة، وأدوات للإجراء. يتم تكوينهما بشكل مستقل ويُكمّلان بعضهما.
+</Note>
+
+---
+
+## البداية السريعة
+
+### 1. إنشاء مجلد المهارة
+
+```
+skills/
+└── code-review/
+    ├── SKILL.md          # مطلوب — التعليمات
+    ├── references/       # اختياري — مستندات مرجعية
+    │   └── style-guide.md
+    └── scripts/          # اختياري — سكربتات قابلة للتنفيذ
+```
+
+### 2. كتابة SKILL.md الخاص بك
+
+```markdown
+---
+name: code-review
+description: Guidelines for conducting thorough code reviews with focus on security and performance.
+metadata:
+  author: your-team
+  version: "1.0"
+---
+
+## إرشادات مراجعة الكود
+
+عند مراجعة الكود، اتبع قائمة التحقق هذه:
+
+1. **الأمان**: تحقق من ثغرات الحقن وتجاوز المصادقة وكشف البيانات
+2. **الأداء**: ابحث عن استعلامات N+1 والتخصيصات غير الضرورية والاستدعاءات المحظورة
+3. **القابلية للقراءة**: تأكد من وضوح التسمية والتعليقات المناسبة والأسلوب المتسق
+4. **الاختبارات**: تحقق من تغطية اختبار كافية للوظائف الجديدة
+
+### مستويات الخطورة
+- **حرج**: ثغرات أمنية، مخاطر فقدان البيانات → حظر الدمج
+- **رئيسي**: مشاكل أداء، أخطاء منطقية → طلب تغييرات
+- **ثانوي**: مسائل أسلوبية، اقتراحات تسمية → الموافقة مع تعليقات
+```
+
+### 3. ربطها بوكيل
+
+```python
+from crewai import Agent
+from crewai_tools import GithubSearchTool, FileReadTool
+
+reviewer = Agent(
+    role="Senior Code Reviewer",
+    goal="Review pull requests for quality and security issues",
+    backstory="Staff engineer with expertise in secure coding practices.",
+    skills=["./skills"],                          # يحقن إرشادات المراجعة
+    tools=[GithubSearchTool(), FileReadTool()],   # يسمح للوكيل بقراءة الكود
+)
+```
+
+الوكيل الآن لديه **خبرة** (من المهارة) و**قدرات** (من الأدوات) معًا.
+
+---
+
+## المهارات + الأدوات: العمل معًا
+
+إليك أنماط شائعة توضح كيف تُكمّل المهارات والأدوات بعضهما:
+
+### النمط 1: مهارات فقط (خبرة المجال، بدون إجراءات مطلوبة)
+
+استخدم عندما يحتاج الوكيل لتعليمات محددة لكن لا يحتاج لاستدعاء خدمات خارجية:
+
+```python
+agent = Agent(
+    role="Technical Writer",
+    goal="Write clear API documentation",
+    backstory="Expert technical writer",
+    skills=["./skills/api-docs-style"],  # إرشادات وقوالب الكتابة
+    # لا حاجة لأدوات — الوكيل يكتب بناءً على السياق المقدم
+)
+```
+
+### النمط 2: أدوات فقط (إجراءات، بدون خبرة خاصة)
+
+استخدم عندما يحتاج الوكيل لاتخاذ إجراءات لكن لا يحتاج لتعليمات مجال محددة:
+
+```python
+from crewai_tools import SerperDevTool, ScrapeWebsiteTool
+
+agent = Agent(
+    role="Web Researcher",
+    goal="Find information about a topic",
+    backstory="Skilled at finding information online",
+    tools=[SerperDevTool(), ScrapeWebsiteTool()],  # يمكنه البحث والاستخراج
+    # لا حاجة لمهارات — البحث العام لا يحتاج إرشادات خاصة
+)
+```
+
+### النمط 3: مهارات + أدوات (خبرة وإجراءات)
+
+النمط الأكثر شيوعًا في العالم الحقيقي. المهارة توفر *كيف* تقترب من العمل؛ الأدوات توفر *ما* يمكن للوكيل فعله:
+
+```python
+from crewai_tools import SerperDevTool, FileReadTool, CodeInterpreterTool
+
+analyst = Agent(
+    role="Security Analyst",
+    goal="Audit infrastructure for vulnerabilities",
+    backstory="Expert in cloud security and compliance",
+    skills=["./skills/security-audit"],   # منهجية وقوائم تحقق التدقيق
+    tools=[
+        SerperDevTool(),                  # البحث عن ثغرات معروفة
+        FileReadTool(),                   # قراءة ملفات التكوين
+        CodeInterpreterTool(),            # تشغيل سكربتات التحليل
+    ],
+)
+```
+
+### النمط 4: مهارات + MCP
+
+المهارات تعمل مع خوادم MCP بنفس الطريقة التي تعمل بها مع الأدوات:
+
+```python
+agent = Agent(
+    role="Data Analyst",
+    goal="Analyze customer data and generate reports",
+    backstory="Expert data analyst with strong statistical background",
+    skills=["./skills/data-analysis"],           # منهجية التحليل
+    mcps=["https://data-warehouse.example.com/sse"],  # وصول بيانات عن بُعد
+)
+```
+
+### النمط 5: مهارات + تطبيقات
+
+المهارات يمكن أن توجّه كيف يستخدم الوكيل تكاملات المنصة:
+
+```python
+agent = Agent(
+    role="Customer Support Agent",
+    goal="Respond to customer inquiries professionally",
+    backstory="Experienced support representative",
+    skills=["./skills/support-playbook"],  # قوالب الردود وقواعد التصعيد
+    apps=["gmail", "zendesk"],             # يمكنه إرسال رسائل بريد وتحديث التذاكر
+)
+```
+
+---
+
+## المهارات على مستوى الطاقم
+
+يمكن تعيين المهارات على الطاقم لتُطبّق على **جميع الوكلاء**:
+
+```python
+from crewai import Crew
+
+crew = Crew(
+    agents=[researcher, writer, reviewer],
+    tasks=[research_task, write_task, review_task],
+    skills=["./skills"],  # جميع الوكلاء يحصلون على هذه المهارات
+)
+```
+
+المهارات على مستوى الوكيل لها الأولوية — إذا تم اكتشاف نفس المهارة في كلا المستويين، يتم استخدام نسخة الوكيل.

+## المهارات مقابل المعرفة
+
+كلا المهارات والمعرفة تُعدّل إرشادات الوكيل، لكنهما يخدمان أغراضًا مختلفة:
+
+| الجانب | المهارات | المعرفة |
+| :--- | :--- | :--- |
+| **ما توفره** | تعليمات، إجراءات، إرشادات | حقائق، بيانات، معلومات |
+| **كيف تُخزّن** | ملفات Markdown (SKILL.md) | مُضمّنة في مخزن متجهي (ChromaDB) |
+| **كيف تُسترجع** | يتم حقن المحتوى الكامل في الإرشادات | البحث الدلالي يجد الأجزاء ذات الصلة |
+| **الأفضل لـ** | المنهجيات، قوائم التحقق، أدلة الأسلوب | مستندات الشركة، معلومات المنتج، بيانات مرجعية |
+| **يُعيّن عبر** | `skills=["./skills"]` | `knowledge_sources=[source]` |
+
+**القاعدة العامة:** إذا كان الوكيل يحتاج لاتباع *عملية*، استخدم مهارة. إذا كان يحتاج للرجوع إلى *بيانات*، استخدم المعرفة.
+

+
+## الأسئلة الشائعة
+
+<AccordionGroup>
+  <Accordion title="هل أحتاج لتعيين المهارات والأدوات معًا؟">
+    يعتمد على حالة الاستخدام. المهارات والأدوات **مستقلتان** — يمكنك استخدام أيّ منهما أو كليهما أو لا شيء.
+
+    - **مهارات فقط**: عندما يحتاج الوكيل خبرة لكن لا يحتاج إجراءات خارجية (مثال: الكتابة بإرشادات أسلوبية)
+    - **أدوات فقط**: عندما يحتاج الوكيل إجراءات لكن لا يحتاج منهجية خاصة (مثال: بحث بسيط على الويب)
+    - **كليهما**: عندما يحتاج الوكيل خبرة وإجراءات (مثال: تدقيق أمني بقوائم تحقق محددة وقدرة على فحص الكود)
+  </Accordion>
+
+  <Accordion title="هل توفر المهارات أدوات تلقائيًا؟">
+    **لا.** حقل `allowed-tools` في SKILL.md هو بيانات وصفية تجريبية فقط — لا يُنشئ أو يحقن أي أدوات. يجب عليك دائمًا تعيين الأدوات بشكل منفصل عبر `tools=[]` أو `mcps=[]` أو `apps=[]`.
+  </Accordion>
+
+  <Accordion title="ماذا يحدث إذا عيّنت نفس المهارة على كل من الوكيل والطاقم؟">
+    المهارة على مستوى الوكيل لها الأولوية. يتم إزالة التكرار حسب الاسم — مهارات الوكيل تُعالج أولاً، لذا إذا ظهر نفس اسم المهارة في كلا المستويين، تُستخدم نسخة الوكيل.
+  </Accordion>
+
+  <Accordion title="ما الحجم الأقصى لمحتوى SKILL.md؟">
+    هناك تحذير ناعم عند 50,000 حرف، لكن بدون حد صارم. حافظ على تركيز المهارات وإيجازها للحصول على أفضل النتائج — الحقن الكبيرة في الإرشادات قد تُشتت انتباه الوكيل.

+
+## Overview
+
+CrewAI agents can be extended with **five distinct capability types**, each serving a different purpose. Understanding when to use each one — and how they work together — is key to building effective agents.
+
+<CardGroup cols={2}>
+  <Card title="Tools" icon="wrench" href="/en/concepts/tools" color="#3B82F6">
+    **Callable functions** — give agents the ability to take action. Web searches, file operations, API calls, code execution.
+  </Card>
+  <Card title="MCP Servers" icon="plug" href="/en/mcp/overview" color="#8B5CF6">
+    **Remote tool servers** — connect agents to external tool servers via the Model Context Protocol. Same effect as tools, but hosted externally.
+  </Card>
+  <Card title="Apps" icon="grid-2" color="#EC4899">
+    **Platform integrations** — connect agents to SaaS apps (Gmail, Slack, Jira, Salesforce) via CrewAI's platform. Runs locally with a platform integration token.
+  </Card>
+  <Card title="Skills" icon="bolt" href="/en/concepts/skills" color="#F59E0B">
+    **Domain expertise** — inject instructions, guidelines, and reference material into agent prompts. Skills tell agents *how to think*.
+  </Card>
+  <Card title="Knowledge" icon="book" href="/en/concepts/knowledge" color="#10B981">
+    **Retrieved facts** — provide agents with data from documents, files, and URLs via semantic search (RAG). Knowledge gives agents *what to know*.
+  </Card>
+</CardGroup>
+
+---
+
+## The Key Distinction
+
+The most important thing to understand: **these capabilities fall into two categories**.
+
+### Action Capabilities (Tools, MCPs, Apps)
+
+These give agents the ability to **do things** — call APIs, read files, search the web, send emails. At execution time, all three resolve into the same internal format (`BaseTool` instances) and appear in a unified tool list the agent can call.
+
+```python
+from crewai import Agent
+from crewai_tools import SerperDevTool, FileReadTool
+
+agent = Agent(
+    role="Researcher",
+    goal="Find and compile market data",
+    backstory="Expert market analyst",
+    tools=[SerperDevTool(), FileReadTool()],  # Local tools
+    mcps=["https://mcp.example.com/sse"],     # Remote MCP server tools
+    apps=["gmail", "google_sheets"],           # Platform integrations
+)
+```
+
+### Context Capabilities (Skills, Knowledge)
+
+These modify the agent's **prompt** — injecting expertise, instructions, or retrieved data before the agent starts reasoning. They don't give agents new actions; they shape how agents think and what information they have access to.
+
+```python
+from crewai import Agent
+
+agent = Agent(
+    role="Security Auditor",
+    goal="Audit cloud infrastructure for vulnerabilities",
+    backstory="Expert in cloud security with 10 years of experience",
+    skills=["./skills/security-audit"],        # Domain instructions
+    knowledge_sources=[pdf_source, url_source], # Retrieved facts
+)
+```
+
+---
+
+## When to Use What
+
+| You need...                                       | Use               | Example                                  |
+| :------------------------------------------------ | :---------------- | :--------------------------------------- |
+| Agent to search the web                           | **Tools**         | `tools=[SerperDevTool()]`                |
+| Agent to call a remote API via MCP                | **MCPs**          | `mcps=["https://api.example.com/sse"]`   |
+| Agent to send emails via Gmail                    | **Apps**          | `apps=["gmail"]`                         |
+| Agent to follow specific procedures               | **Skills**        | `skills=["./skills/code-review"]`        |
+| Agent to reference company docs                   | **Knowledge**     | `knowledge_sources=[pdf_source]`         |
+| Agent to search the web AND follow review guidelines | **Tools + Skills** | Use both together                     |
+
+---
+
+## Combining Capabilities
+
+In practice, agents often use **multiple capability types together**. Here's a realistic example:
+
+```python
+from crewai import Agent
+from crewai_tools import SerperDevTool, FileReadTool, CodeInterpreterTool
+
+# A fully-equipped research agent
+researcher = Agent(
+    role="Senior Research Analyst",
+    goal="Produce comprehensive market analysis reports",
+    backstory="Expert analyst with deep industry knowledge",
+
+    # ACTION: What the agent can DO
+    tools=[
+        SerperDevTool(),         # Search the web
+        FileReadTool(),          # Read local files
+        CodeInterpreterTool(),   # Run Python code for analysis
+    ],
+    mcps=["https://data-api.example.com/sse"],  # Access remote data API
+    apps=["google_sheets"],                      # Write to Google Sheets
+
+    # CONTEXT: What the agent KNOWS
+    skills=["./skills/research-methodology"],    # How to conduct research
+    knowledge_sources=[company_docs],            # Company-specific data
+)
+```
+
+---
+
+## Comparison Table
+
+| Feature | Tools | MCPs | Apps | Skills | Knowledge |
+| :--- | :---: | :---: | :---: | :---: | :---: |
+| **Gives agent actions** | ✅ | ✅ | ✅ | ❌ | ❌ |
+| **Modifies prompt** | ❌ | ❌ | ❌ | ✅ | ✅ |
+| **Requires code** | Yes | Config only | Config only | Markdown only | Config only |

+Skills are self-contained directories that provide agents with **domain-specific instructions, guidelines, and reference material**. Each skill is defined by a `SKILL.md` file with YAML frontmatter and a markdown body.
 
-Skills use **progressive disclosure** — metadata is loaded first, full instructions only when activated, and resource catalogs only when needed.
+When activated, a skill's instructions are injected directly into the agent's task prompt — giving the agent expertise without requiring any code changes.
 
-## Directory Structure
+<Note type="info" title="Skills vs Tools — The Key Distinction">
+**Skills are NOT tools.** This is the most common point of confusion.
+
+- **Skills** inject *instructions and context* into the agent's prompt. They tell the agent *how to think* about a problem.
+- **Tools** give the agent *callable functions* to take action (search, read files, call APIs).
+
+You often need **both**: skills for expertise, tools for action. They are configured independently and complement each other.
+</Note>
+
+---
+
+## Quick Start
+
+### 1. Create a Skill Directory
 
 ```
-my-skill/
-├── SKILL.md            # Required — frontmatter + instructions
-├── scripts/            # Optional — executable scripts
-├── references/         # Optional — reference documents
-└── assets/             # Optional — static files (configs, data)
+skills/
+└── code-review/
+    ├── SKILL.md          # Required — instructions
+    ├── references/       # Optional — reference docs
+    │   └── style-guide.md
+    └── scripts/          # Optional — executable scripts
 ```
 
-The directory name must match the `name` field in `SKILL.md`.
+### 2. Write Your SKILL.md
+
+```markdown
+---
+name: code-review
+description: Guidelines for conducting thorough code reviews with focus on security and performance.
+metadata:
+  author: your-team
+  version: "1.0"
+---
+
+## Code Review Guidelines
+
+When reviewing code, follow this checklist:
+
+1. **Security**: Check for injection vulnerabilities, auth bypasses, and data exposure
+2. **Performance**: Look for N+1 queries, unnecessary allocations, and blocking calls
+3. **Readability**: Ensure clear naming, appropriate comments, and consistent style
+4. **Testing**: Verify adequate test coverage for new functionality
+
+### Severity Levels
+- **Critical**: Security vulnerabilities, data loss risks → block merge
+- **Major**: Performance issues, logic errors → request changes
+- **Minor**: Style issues, naming suggestions → approve with comments
+```
+
+### 3. Attach to an Agent
+
+```python
+from crewai import Agent
+from crewai_tools import GithubSearchTool, FileReadTool
+
+reviewer = Agent(
+    role="Senior Code Reviewer",
+    goal="Review pull requests for quality and security issues",
+    backstory="Staff engineer with expertise in secure coding practices.",
+    skills=["./skills"],                          # Injects review guidelines
+    tools=[GithubSearchTool(), FileReadTool()],   # Lets agent read code
+)
+```
+
+The agent now has both **expertise** (from the skill) and **capabilities** (from the tools).
+
+---
+
+## Skills + Tools: Working Together
+
+Here are common patterns showing how skills and tools complement each other:
+
+### Pattern 1: Skills Only (Domain Expertise, No Actions Needed)
+
+Use when the agent needs specific instructions but doesn't need to call external services:
+
+```python
+agent = Agent(
+    role="Technical Writer",
+    goal="Write clear API documentation",
+    backstory="Expert technical writer",
+    skills=["./skills/api-docs-style"],  # Writing guidelines and templates
+    # No tools needed — agent writes based on provided context
+)
+```
+
+### Pattern 2: Tools Only (Actions, No Special Expertise)
+
+Use when the agent needs to take action but doesn't need domain-specific instructions:
+
+```python
+from crewai_tools import SerperDevTool, ScrapeWebsiteTool
+
+agent = Agent(
+    role="Web Researcher",
+    goal="Find information about a topic",
+    backstory="Skilled at finding information online",
+    tools=[SerperDevTool(), ScrapeWebsiteTool()],  # Can search and scrape
+    # No skills needed — general research doesn't need special guidelines
+)
+```
+
+### Pattern 3: Skills + Tools (Expertise AND Actions)
+
+The most common real-world pattern. The skill provides *how* to approach the work; tools provide *what* the agent can do:
+
+```python
+from crewai_tools import SerperDevTool, FileReadTool, CodeInterpreterTool
+
+analyst = Agent(
+    role="Security Analyst",
+    goal="Audit infrastructure for vulnerabilities",
+    backstory="Expert in cloud security and compliance",
+    skills=["./skills/security-audit"],   # Audit methodology and checklists
+    tools=[
+        SerperDevTool(),                  # Research known vulnerabilities
+        FileReadTool(),                   # Read config files
+        CodeInterpreterTool(),            # Run analysis scripts
+    ],
+)
+```
+
+### Pattern 4: Skills + MCPs
+
+Skills work alongside MCP servers the same way they work with tools:
+
+```python
+agent = Agent(
+    role="Data Analyst",
+    goal="Analyze customer data and generate reports",
+    backstory="Expert data analyst with strong statistical background",
+    skills=["./skills/data-analysis"],           # Analysis methodology
+    mcps=["https://data-warehouse.example.com/sse"],  # Remote data access
+)
+```
+
+### Pattern 5: Skills + Apps
+
+Skills can guide how an agent uses platform integrations:
+
+```python
+agent = Agent(
+    role="Customer Support Agent",
+    goal="Respond to customer inquiries professionally",
+    backstory="Experienced support representative",
+    skills=["./skills/support-playbook"],  # Response templates and escalation rules
+    apps=["gmail", "zendesk"],             # Can send emails and update tickets
+)
+```
+
+---
+
+## Crew-Level Skills
+
+Skills can be set on a crew to apply to **all agents**:
+
+```python
+from crewai import Crew
+
+crew = Crew(
+    agents=[researcher, writer, reviewer],
+    tasks=[research_task, write_task, review_task],
+    skills=["./skills"],  # All agents get these skills
+)
+```
+
+Agent-level skills take priority — if the same skill is discovered at both levels, the agent's version is used.

-### Agent-level Skills
+## Directory Structure
 
-Pass skill directory paths to an agent:
-
-```python
-from crewai import Agent
-
-agent = Agent(
-    role="Researcher",
-    goal="Find relevant information",
-    backstory="An expert researcher.",
-    skills=["./skills"],  # discovers all skills in this directory
-)

+├── references/         # Optional — reference documents
+└── assets/             # Optional — static files (configs, data)
 ```
 
-### Crew-level Skills
+The directory name must match the `name` field in `SKILL.md`. The `scripts/`, `references/`, and `assets/` directories are available on the skill's `path` for agents that need to reference files directly.
 
-Skill paths on a crew are merged into every agent:

-```python
-from crewai import Crew
+## Pre-loading Skills
 
-crew = Crew(
-    agents=[agent],
-    tasks=[task],
-    skills=["./skills"],
-)

 ## How Skills Are Loaded
 
-Skills load progressively — only the data needed at each stage is read:
+Skills use **progressive disclosure** — only loading what's needed at each stage:
 
-| Stage            | What's loaded                                     | When               |

-| Discovery        | Name, description, frontmatter fields             | `discover_skills()` |
-| Activation       | Full SKILL.md body text                           | `activate_skill()` |

+| Discovery  | Name, description, frontmatter fields | `discover_skills()` |
+| Activation | Full SKILL.md body text               | `activate_skill()`  |
 
-During normal agent execution, skills are automatically discovered and activated. The `scripts/`, `references/`, and `assets/` directories are available on the skill's `path` for agents that need to reference files directly.
+During normal agent execution (passing directory paths via `skills=["./skills"]`), skills are automatically discovered and activated. The progressive loading only matters when using the programmatic API.

+
+## Skills vs Knowledge
+
+Both skills and knowledge modify the agent's prompt, but they serve different purposes:
+
+| Aspect | Skills | Knowledge |
+| :--- | :--- | :--- |
+| **What it provides** | Instructions, procedures, guidelines | Facts, data, information |
+| **How it's stored** | Markdown files (SKILL.md) | Embedded in vector store (ChromaDB) |
+| **How it's retrieved** | Entire body injected into prompt | Semantic search finds relevant chunks |
+| **Best for** | Methodology, checklists, style guides | Company docs, product info, reference data |
+| **Set via** | `skills=["./skills"]` | `knowledge_sources=[source]` |
+
+**Rule of thumb:** If the agent needs to follow a *process*, use a skill. If the agent needs to reference *data*, use knowledge.
+
+---
+
+## Common Questions
+
+<AccordionGroup>
+  <Accordion title="Do I need to set skills AND tools?">
+    It depends on your use case. Skills and tools are **independent** — you can use either, both, or neither.
+
+    - **Skills alone**: When the agent needs expertise but no external actions (e.g., writing with style guidelines)
+    - **Tools alone**: When the agent needs actions but no special methodology (e.g., simple web search)
+    - **Both**: When the agent needs expertise AND actions (e.g., security audit with specific checklists AND ability to scan code)
+  </Accordion>
+
+  <Accordion title="Do skills automatically provide tools?">
+    **No.** The `allowed-tools` field in SKILL.md is experimental metadata only — it does not provision or inject any tools. You must always set tools separately via `tools=[]`, `mcps=[]`, or `apps=[]`.
+  </Accordion>
+
+  <Accordion title="What happens if I set the same skill on both an agent and its crew?">
+    The agent-level skill takes priority. Skills are deduplicated by name — the agent's skills are processed first, so if the same skill name appears at both levels, the agent's version is used.
+  </Accordion>
+
+  <Accordion title="How large can a SKILL.md body be?">
+    There's a soft warning at 50,000 characters, but no hard limit. Keep skills focused and concise for best results — large prompt injections can dilute the agent's attention.
+  </Accordion>

+
+## 핵심 구분
+
+가장 중요한 점: **이 기능들은 두 가지 범주로 나뉩니다**.
+
+### 액션 기능 (도구, MCP, 앱)
+
+에이전트에게 **무언가를 할 수 있는** 능력을 부여합니다 — API 호출, 파일 읽기, 웹 검색, 이메일 전송. 실행 시점에 세 가지 모두 동일한 내부 형식(`BaseTool` 인스턴스)으로 변환되며, 에이전트가 호출할 수 있는 통합 도구 목록에 나타납니다.
+
+```python
+from crewai import Agent
+from crewai_tools import SerperDevTool, FileReadTool
+
+agent = Agent(
+    role="Researcher",
+    goal="Find and compile market data",
+    backstory="Expert market analyst",
+    tools=[SerperDevTool(), FileReadTool()],  # 로컬 도구
+    mcps=["https://mcp.example.com/sse"],     # 원격 MCP 서버 도구
+    apps=["gmail", "google_sheets"],           # 플랫폼 통합
+)
+```
+
+### 컨텍스트 기능 (스킬, 지식)
+
+에이전트의 **프롬프트**를 수정합니다 — 에이전트가 추론을 시작하기 전에 전문성, 지침 또는 검색된 데이터를 주입합니다. 에이전트에게 새로운 액션을 제공하는 것이 아니라, 에이전트가 어떻게 생각하고 어떤 정보에 접근할 수 있는지를 형성합니다.
+
+```python
+from crewai import Agent
+
+agent = Agent(
+    role="Security Auditor",
+    goal="Audit cloud infrastructure for vulnerabilities",
+    backstory="Expert in cloud security with 10 years of experience",
+    skills=["./skills/security-audit"],        # 도메인 지침
+    knowledge_sources=[pdf_source, url_source], # 검색된 사실
+)
+```

 ## 개요
 
-스킬은 에이전트에게 도메인별 지침, 참조 자료, 에셋을 제공하는 자체 포함 디렉터리입니다. 각 스킬은 YAML 프론트매터와 마크다운 본문이 포함된 `SKILL.md` 파일로 정의됩니다.
+스킬은 에이전트에게 **도메인별 지침, 가이드라인 및 참조 자료**를 제공하는 자체 포함 디렉터리입니다. 각 스킬은 YAML 프론트매터와 마크다운 본문이 포함된 `SKILL.md` 파일로 정의됩니다.
 
-스킬은 **점진적 공개**를 사용합니다 — 메타데이터가 먼저 로드되고, 활성화 시에만 전체 지침이 로드되며, 필요할 때만 리소스 카탈로그가 로드됩니다.
+활성화되면 스킬의 지침이 에이전트의 작업 프롬프트에 직접 주입됩니다 — 코드 변경 없이 에이전트에게 전문성을 부여합니다.
 
-## 디렉터리 구조
+<Note type="info" title="스킬 vs 도구 — 핵심 구분">
+**스킬은 도구가 아닙니다.** 이것이 가장 흔한 혼동 포인트입니다.
+
+- **스킬**은 에이전트의 프롬프트에 *지침과 컨텍스트*를 주입합니다. 에이전트에게 문제에 대해 *어떻게 생각할지*를 알려줍니다.
+- **도구**는 에이전트에게 행동을 취할 수 있는 *호출 가능한 함수*를 제공합니다 (검색, 파일 읽기, API 호출).
+
+흔히 **둘 다** 필요합니다: 전문성을 위한 스킬과 행동을 위한 도구. 이들은 독립적으로 구성되며 서로 보완합니다.
+</Note>
+
+---
+
+## 빠른 시작
+
+### 1. 스킬 디렉터리 생성
 
 ```

-├── SKILL.md            # 필수 — 프론트매터 + 지침
-├── scripts/            # 선택 — 실행 가능한 스크립트

+    └── scripts/          # 선택 — 실행 가능한 스크립트
 ```
 
-디렉터리 이름은 `SKILL.md`의 `name` 필드와 일치해야 합니다.
+### 2. SKILL.md 작성
+
+```markdown
+---
+name: code-review
+description: Guidelines for conducting thorough code reviews with focus on security and performance.
+metadata:
+  author: your-team
+  version: "1.0"
+---
+
+## 코드 리뷰 가이드라인
+
+코드를 리뷰할 때 이 체크리스트를 따르세요:
+
+1. **보안**: 인젝션 취약점, 인증 우회, 데이터 노출 확인
+2. **성능**: N+1 쿼리, 불필요한 할당, 블로킹 호출 확인
+3. **가독성**: 명확한 네이밍, 적절한 주석, 일관된 스타일 보장
+4. **테스트**: 새로운 기능에 대한 적절한 테스트 커버리지 확인
+
+### 심각도 수준
+- **크리티컬**: 보안 취약점, 데이터 손실 위험 → 머지 차단
+- **메이저**: 성능 문제, 로직 오류 → 변경 요청
+- **마이너**: 스타일 문제, 네이밍 제안 → 코멘트와 함께 승인
+```
+
+### 3. 에이전트에 연결
+
+```python
+from crewai import Agent
+from crewai_tools import GithubSearchTool, FileReadTool
+
+reviewer = Agent(
+    role="Senior Code Reviewer",
+    goal="Review pull requests for quality and security issues",
+    backstory="Staff engineer with expertise in secure coding practices.",
+    skills=["./skills"],                          # 리뷰 가이드라인 주입
+    tools=[GithubSearchTool(), FileReadTool()],   # 에이전트가 코드를 읽을 수 있게 함
+)
+```
+
+이제 에이전트는 **전문성** (스킬에서)과 **기능** (도구에서) 모두를 갖추게 됩니다.
+
+---
+
+## 스킬 + 도구: 함께 작동하기
+
+스킬과 도구가 어떻게 보완하는지 보여주는 일반적인 패턴입니다:
+
+### 패턴 1: 스킬만 (도메인 전문성, 액션 불필요)
+
+에이전트가 특정 지침이 필요하지만 외부 서비스를 호출할 필요가 없을 때 사용:
+
+```python
+agent = Agent(
+    role="Technical Writer",
+    goal="Write clear API documentation",
+    backstory="Expert technical writer",
+    skills=["./skills/api-docs-style"],  # 작성 가이드라인 및 템플릿
+    # 도구 불필요 — 에이전트가 제공된 컨텍스트를 기반으로 작성
+)
+```
+
+### 패턴 2: 도구만 (액션, 특별한 전문성 불필요)
+
+에이전트가 행동을 취해야 하지만 도메인별 지침이 필요 없을 때 사용:
+
+```python
+from crewai_tools import SerperDevTool, ScrapeWebsiteTool
+
+agent = Agent(
+    role="Web Researcher",
+    goal="Find information about a topic",
+    backstory="Skilled at finding information online",
+    tools=[SerperDevTool(), ScrapeWebsiteTool()],  # 검색 및 스크래핑 가능
+    # 스킬 불필요 — 일반 연구에는 특별한 가이드라인이 필요 없음
+)
+```
+
+### 패턴 3: 스킬 + 도구 (전문성 AND 액션)
+
+가장 일반적인 실제 패턴. 스킬은 작업에 *어떻게* 접근할지를 제공하고, 도구는 에이전트가 *무엇을* 할 수 있는지를 제공합니다:
+
+```python
+from crewai_tools import SerperDevTool, FileReadTool, CodeInterpreterTool
+
+analyst = Agent(
+    role="Security Analyst",
+    goal="Audit infrastructure for vulnerabilities",
+    backstory="Expert in cloud security and compliance",
+    skills=["./skills/security-audit"],   # 감사 방법론 및 체크리스트
+    tools=[
+        SerperDevTool(),                  # 알려진 취약점 조사
+        FileReadTool(),                   # 설정 파일 읽기
+        CodeInterpreterTool(),            # 분석 스크립트 실행
+    ],
+)
+```
+
+### 패턴 4: 스킬 + MCP
+
+스킬은 도구와 마찬가지로 MCP 서버와 함께 작동합니다:
+
+```python
+agent = Agent(
+    role="Data Analyst",
+    goal="Analyze customer data and generate reports",
+    backstory="Expert data analyst with strong statistical background",
+    skills=["./skills/data-analysis"],           # 분석 방법론
+    mcps=["https://data-warehouse.example.com/sse"],  # 원격 데이터 접근
+)
+```
+
+### 패턴 5: 스킬 + 앱
+
+스킬은 에이전트가 플랫폼 통합을 사용하는 방법을 안내할 수 있습니다:
+
+```python
+agent = Agent(
+    role="Customer Support Agent",
+    goal="Respond to customer inquiries professionally",
+    backstory="Experienced support representative",
+    skills=["./skills/support-playbook"],  # 응답 템플릿 및 에스컬레이션 규칙
+    apps=["gmail", "zendesk"],             # 이메일 전송 및 티켓 업데이트 가능
+)
+```
+
+---
+
+## 크루 레벨 스킬
+
+스킬을 크루에 설정하여 **모든 에이전트**에 적용할 수 있습니다:
+
+```python
+from crewai import Crew
+
+crew = Crew(
+    agents=[researcher, writer, reviewer],
+    tasks=[research_task, write_task, review_task],
+    skills=["./skills"],  # 모든 에이전트가 이 스킬을 받음
+)
+```
+
+에이전트 레벨 스킬이 우선합니다 — 동일한 스킬이 양쪽 레벨에서 발견되면 에이전트의 버전이 사용됩니다.

+
+Agentes CrewAI podem ser estendidos com **cinco tipos distintos de capacidades**, cada um servindo a um propósito diferente. Entender quando usar cada um — e como eles funcionam juntos — é fundamental para construir agentes eficazes.
+
+<CardGroup cols={2}>

+  </Card>
+</CardGroup>
+
+---
+
+## A Distinção Fundamental
+
+O mais importante a entender: **essas capacidades se dividem em duas categorias**.
+
+### Capacidades de Ação (Ferramentas, MCPs, Apps)
+
+Estas dão aos agentes a capacidade de **fazer coisas** — chamar APIs, ler arquivos, buscar na web, enviar emails. No momento da execução, os três tipos se resolvem no mesmo formato interno (instâncias de `BaseTool`) e aparecem em uma lista unificada de ferramentas que o agente pode chamar.
+
+```python
+from crewai import Agent
+from crewai_tools import SerperDevTool, FileReadTool
+
+agent = Agent(
+    role="Researcher",
+    goal="Find and compile market data",
+    backstory="Expert market analyst",
+    tools=[SerperDevTool(), FileReadTool()],  # Ferramentas locais
+    mcps=["https://mcp.example.com/sse"],     # Ferramentas de servidor MCP remoto
+    apps=["gmail", "google_sheets"],           # Integrações com plataformas
+)
+```
+
+### Capacidades de Contexto (Skills, Knowledge)
+
+Estas modificam o **prompt** do agente — injetando expertise, instruções ou dados recuperados antes do agente começar a raciocinar. Não dão aos agentes novas ações; elas moldam como os agentes pensam e a quais informações têm acesso.
+
+```python
+from crewai import Agent
+
+agent = Agent(
+    role="Security Auditor",
+    goal="Audit cloud infrastructure for vulnerabilities",
+    backstory="Expert in cloud security with 10 years of experience",
+    skills=["./skills/security-audit"],        # Instruções de domínio
+    knowledge_sources=[pdf_source, url_source], # Fatos recuperados
+)
+```
+
+---
+
+## Quando Usar o Quê
+
+| Você precisa...                                          | Use               | Exemplo                                  |
+| :------------------------------------------------------- | :---------------- | :--------------------------------------- |
+| Agente buscar na web                                     | **Ferramentas**   | `tools=[SerperDevTool()]`                |
+| Agente chamar uma API remota via MCP                     | **MCPs**          | `mcps=["https://api.example.com/sse"]`   |
+| Agente enviar emails pelo Gmail                          | **Apps**          | `apps=["gmail"]`                         |
+| Agente seguir procedimentos específicos                  | **Skills**        | `skills=["./skills/code-review"]`        |
+| Agente consultar documentos da empresa                   | **Knowledge**     | `knowledge_sources=[pdf_source]`         |
+| Agente buscar na web E seguir diretrizes de revisão      | **Ferramentas + Skills** | Use ambos juntos                  |
+
+---
+
+## Combinando Capacidades
+
+Na prática, agentes frequentemente usam **múltiplos tipos de capacidades juntos**. Aqui está um exemplo realista:
+
+```python
+from crewai import Agent
+from crewai_tools import SerperDevTool, FileReadTool, CodeInterpreterTool
+
+# Um agente de pesquisa totalmente equipado
+researcher = Agent(
+    role="Senior Research Analyst",
+    goal="Produce comprehensive market analysis reports",
+    backstory="Expert analyst with deep industry knowledge",
+
+    # AÇÃO: O que o agente pode FAZER
+    tools=[
+        SerperDevTool(),         # Buscar na web
+        FileReadTool(),          # Ler arquivos locais
+        CodeInterpreterTool(),   # Executar código Python para análise
+    ],
+    mcps=["https://data-api.example.com/sse"],  # Acessar API de dados remota
+    apps=["google_sheets"],                      # Escrever no Google Sheets
+
+    # CONTEXTO: O que o agente SABE
+    skills=["./skills/research-methodology"],    # Como conduzir pesquisas
+    knowledge_sources=[company_docs],            # Dados específicos da empresa
+)
+```
+
+---
+
+## Tabela Comparativa
+
+| Característica | Ferramentas | MCPs | Apps | Skills | Knowledge |
+| :--- | :---: | :---: | :---: | :---: | :---: |
+| **Dá ações ao agente** | ✅ | ✅ | ✅ | ❌ | ❌ |
+| **Modifica o prompt** | ❌ | ❌ | ❌ | ✅ | ✅ |

+Skills são diretórios autocontidos que fornecem aos agentes **instruções, diretrizes e material de referência específicos de domínio**. Cada skill é definida por um arquivo `SKILL.md` com frontmatter YAML e um corpo em markdown.
 
-Skills usam **divulgação progressiva** — metadados são carregados primeiro, instruções completas apenas quando ativadas, e catálogos de recursos apenas quando necessário.
+Quando ativada, as instruções de uma skill são injetadas diretamente no prompt da tarefa do agente — dando ao agente expertise sem exigir alterações de código.
 
-## Estrutura de Diretório
+<Note type="info" title="Skills vs Ferramentas — A Distinção Fundamental">
+**Skills NÃO são ferramentas.** Este é o ponto de confusão mais comum.
+
+- **Skills** injetam *instruções e contexto* no prompt do agente. Elas dizem ao agente *como pensar* sobre um problema.
+- **Ferramentas** dão ao agente *funções chamáveis* para tomar ações (buscar, ler arquivos, chamar APIs).
+
+Frequentemente você precisa de **ambos**: skills para expertise, ferramentas para ação. Eles são configurados independentemente e se complementam.

-├── SKILL.md            # Obrigatório — frontmatter + instruções
-├── scripts/            # Opcional — scripts executáveis

-└── assets/             # Opcional — arquivos estáticos (configs, dados)

+    │   └── style-guide.md
+    └── scripts/          # Opcional — scripts executáveis
 ```
 
-O nome do diretório deve corresponder ao campo `name` no `SKILL.md`.
+### 2. Escreva seu SKILL.md
+
+```markdown
+---
+name: code-review
+description: Guidelines for conducting thorough code reviews with focus on security and performance.
+metadata:
+  author: your-team
+  version: "1.0"
+---
+
+## Diretrizes de Code Review
+
+Ao revisar código, siga esta checklist:
+
+1. **Segurança**: Verifique vulnerabilidades de injeção, bypasses de autenticação e exposição de dados
+2. **Performance**: Procure por queries N+1, alocações desnecessárias e chamadas bloqueantes
+3. **Legibilidade**: Garanta nomenclatura clara, comentários apropriados e estilo consistente
+4. **Testes**: Verifique cobertura adequada de testes para novas funcionalidades
+
+### Níveis de Severidade
+- **Crítico**: Vulnerabilidades de segurança, riscos de perda de dados → bloquear merge
+- **Major**: Problemas de performance, erros de lógica → solicitar alterações
+- **Minor**: Questões de estilo, sugestões de nomenclatura → aprovar com comentários
+```
+
+### 3. Anexe a um Agente
+
+```python
+from crewai import Agent
+from crewai_tools import GithubSearchTool, FileReadTool
+
+reviewer = Agent(
+    role="Senior Code Reviewer",
+    goal="Review pull requests for quality and security issues",
+    backstory="Staff engineer with expertise in secure coding practices.",
+    skills=["./skills"],                          # Injeta diretrizes de revisão
+    tools=[GithubSearchTool(), FileReadTool()],   # Permite ao agente ler código
+)
+```
+
+O agente agora tem tanto **expertise** (da skill) quanto **capacidades** (das ferramentas).
+
+---
+
+## Skills + Ferramentas: Trabalhando Juntos
+
+Aqui estão padrões comuns mostrando como skills e ferramentas se complementam:
+
+### Padrão 1: Apenas Skills (Expertise de Domínio, Sem Ações Necessárias)
+
+Use quando o agente precisa de instruções específicas mas não precisa chamar serviços externos:
+
+```python
+agent = Agent(
+    role="Technical Writer",
+    goal="Write clear API documentation",
+    backstory="Expert technical writer",
+    skills=["./skills/api-docs-style"],  # Diretrizes e templates de escrita
+    # Sem ferramentas necessárias — agente escreve baseado no contexto fornecido
+)
+```
+
+### Padrão 2: Apenas Ferramentas (Ações, Sem Expertise Especial)
+
+Use quando o agente precisa tomar ações mas não precisa de instruções específicas de domínio:
+
+```python
+from crewai_tools import SerperDevTool, ScrapeWebsiteTool
+
+agent = Agent(
+    role="Web Researcher",
+    goal="Find information about a topic",
+    backstory="Skilled at finding information online",
+    tools=[SerperDevTool(), ScrapeWebsiteTool()],  # Pode buscar e extrair dados
+    # Sem skills necessárias — pesquisa geral não precisa de diretrizes especiais
+)
+```
+
+### Padrão 3: Skills + Ferramentas (Expertise E Ações)
+
+O padrão mais comum no mundo real. A skill fornece *como* abordar o trabalho; ferramentas fornecem *o que* o agente pode fazer:
+
+```python
+from crewai_tools import SerperDevTool, FileReadTool, CodeInterpreterTool
+
+analyst = Agent(
+    role="Security Analyst",
+    goal="Audit infrastructure for vulnerabilities",
+    backstory="Expert in cloud security and compliance",
+    skills=["./skills/security-audit"],   # Metodologia e checklists de auditoria
+    tools=[
+        SerperDevTool(),                  # Pesquisar vulnerabilidades conhecidas
+        FileReadTool(),                   # Ler arquivos de configuração
+        CodeInterpreterTool(),            # Executar scripts de análise
+    ],
+)
+```
+
+### Padrão 4: Skills + MCPs
+
+Skills funcionam junto com servidores MCP da mesma forma que com ferramentas:
+
+```python
+agent = Agent(
+    role="Data Analyst",
+    goal="Analyze customer data and generate reports",
+    backstory="Expert data analyst with strong statistical background",
+    skills=["./skills/data-analysis"],           # Metodologia de análise
+    mcps=["https://data-warehouse.example.com/sse"],  # Acesso remoto a dados
+)
+```
+
+### Padrão 5: Skills + Apps
+
+Skills podem guiar como um agente usa integrações de plataforma:
+
+```python
+agent = Agent(
+    role="Customer Support Agent",
+    goal="Respond to customer inquiries professionally",
+    backstory="Experienced support representative",
+    skills=["./skills/support-playbook"],  # Templates de resposta e regras de escalação
+    apps=["gmail", "zendesk"],             # Pode enviar emails e atualizar tickets
+)
+```
+
+---
+
+## Skills no Nível do Crew
+
+Skills podem ser definidas no crew para aplicar a **todos os agentes**:
+
+```python
+from crewai import Crew
+
+crew = Crew(
+    agents=[researcher, writer, reviewer],
+    tasks=[research_task, write_task, review_task],
+    skills=["./skills"],  # Todos os agentes recebem essas skills
+)
+```
+
+Skills no nível do agente têm prioridade — se a mesma skill é descoberta em ambos os níveis, a versão do agente é usada.

+└── assets/             # Opcional — arquivos estáticos (configs, dados)
 ```
 
-### Skills no Nível do Crew
+O nome do diretório deve corresponder ao campo `name` no `SKILL.md`. Os diretórios `scripts/`, `references/` e `assets/` estão disponíveis no `path` da skill para agentes que precisam referenciar arquivos diretamente.

 ## Como as Skills São Carregadas
 
-Skills carregam progressivamente — apenas os dados necessários em cada etapa são lidos:
+Skills usam **divulgação progressiva** — carregando apenas o necessário em cada estágio:
 
-| Etapa            | O que é carregado                                  | Quando              |

+## Skills vs Knowledge
+
+Tanto skills quanto knowledge modificam o prompt do agente, mas servem propósitos diferentes:
+
+| Aspecto | Skills | Knowledge |
+| :--- | :--- | :--- |
+| **O que fornece** | Instruções, procedimentos, diretrizes | Fatos, dados, informações |
+| **Como é armazenado** | Arquivos Markdown (SKILL.md) | Embarcado em banco vetorial (ChromaDB) |
+| **Como é recuperado** | Corpo inteiro injetado no prompt | Busca semântica encontra trechos relevantes |
+| **Melhor para** | Metodologia, checklists, guias de estilo | Documentos da empresa, info de produto, dados de referência |
+| **Definido via** | `skills=["./skills"]` | `knowledge_sources=[source]` |
+
+**Regra prática:** Se o agente precisa seguir um *processo*, use uma skill. Se o agente precisa consultar *dados*, use knowledge.

+## Perguntas Frequentes
+
+<AccordionGroup>
+  <Accordion title="Preciso definir skills E ferramentas?">
+    Depende do seu caso de uso. Skills e ferramentas são **independentes** — você pode usar qualquer um, ambos ou nenhum.
+
+    - **Apenas skills**: Quando o agente precisa de expertise mas não de ações externas (ex: escrever com diretrizes de estilo)
+    - **Apenas ferramentas**: Quando o agente precisa de ações mas não de metodologia especial (ex: busca simples na web)
+    - **Ambos**: Quando o agente precisa de expertise E ações (ex: auditoria de segurança com checklists específicas E capacidade de escanear código)
+  </Accordion>
+
+  <Accordion title="Skills fornecem ferramentas automaticamente?">
+    **Não.** O campo `allowed-tools` no SKILL.md é apenas metadado experimental — ele não provisiona nem injeta nenhuma ferramenta. Você deve sempre definir ferramentas separadamente via `tools=[]`, `mcps=[]` ou `apps=[]`.
+  </Accordion>
+
+  <Accordion title="O que acontece se eu definir a mesma skill tanto no agente quanto no crew?">
+    A skill no nível do agente tem prioridade. Skills são deduplicadas por nome — as skills do agente são processadas primeiro, então se o mesmo nome de skill aparece em ambos os níveis, a versão do agente é usada.
+  </Accordion>
+
+  <Accordion title="Qual o tamanho máximo do corpo do SKILL.md?">
+    Há um aviso suave em 50.000 caracteres, mas sem limite rígido. Mantenha skills focadas e concisas para melhores resultados — injeções de prompt muito grandes podem diluir a atenção do agente.

 As ferramentas do CrewAI capacitam agentes com habilidades que vão desde busca na web e análise de dados até colaboração e delegação de tarefas entre colegas de trabalho.
 Esta documentação descreve como criar, integrar e aproveitar essas ferramentas dentro do framework CrewAI, incluindo um novo foco em ferramentas de colaboração.
 
+<Note type="info" title="Ferramentas são um dos cinco tipos de capacidades de agentes">
