sc-explain

Code & Concept Explanation Skill

Educational explanations with adaptive depth and format.

Quick Start

# Basic code explanation
/sc:explain authentication.js --level basic

# Framework concept
/sc:explain react-hooks --level intermediate --context react

# System architecture
/sc:explain microservices-system --level advanced --format interactive

Behavioral Flow

1. Analyze - Examine target code or concept
2. Assess - Determine audience level and depth
3. Structure - Plan explanation with progressive complexity
4. Generate - Create clear explanations with examples
5. Validate - Verify accuracy and educational effectiveness

Flags

Flag	Type	Default	Description
--level	string	intermediate	basic, intermediate, advanced
--format	string	text	text, examples, interactive
--context	string	-	Domain context (react, security, etc.)

Personas Activated

• communicator - Learning-optimized explanations
• architect - System design context
• guardian - Security practice explanations

MCP Integration

PAL MCP (Multi-Perspective Explanations)

Tool	When to Use	Purpose
mcp__pal__consensus	Complex topics	Cross-perspective validation
mcp__pal__chat	Clarification	Get alternative explanations
mcp__pal__thinkdeep	Deep concepts	Multi-stage exploration
mcp__pal__apilookup	Current APIs	Get up-to-date documentation
mcp__pal__challenge	Verify accuracy	Challenge explanation correctness

PAL Usage Patterns

# Multi-perspective explanation for complex topic
mcp__pal__consensus(
    models=[
        {"model": "gpt-5.2", "stance": "neutral"},
        {"model": "gemini-3-pro", "stance": "neutral"}
    ],
    step="Explain: How does React's reconciliation algorithm work?"
)

# Get alternative explanation approach
mcp__pal__chat(
    prompt="Explain React hooks to someone familiar with Vue composition API",
    model="gpt-5.2",
    thinking_mode="medium"
)

# Deep dive into complex concept
mcp__pal__thinkdeep(
    step="Understanding Kubernetes pod scheduling algorithm",
    hypothesis="Priority-based scheduling with resource constraints",
    confidence="medium",
    focus_areas=["scheduling", "resource_management", "affinity"]
)

# Verify explanation accuracy
mcp__pal__challenge(
    prompt="Is my explanation of OAuth2 refresh tokens technically accurate?"
)

# Get current API/framework documentation
mcp__pal__apilookup(
    prompt="Get current React 19 documentation for use hook"
)

Rube MCP (Research & Sharing)

Tool	When to Use	Purpose
mcp__rube__RUBE_SEARCH_TOOLS	Web research	Find tutorials, docs, examples
mcp__rube__RUBE_MULTI_EXECUTE_TOOL	Share explanations	Post to Notion, Slack, etc.

Rube Usage Patterns

# Research current best practices
mcp__rube__RUBE_SEARCH_TOOLS(queries=[
    {"use_case": "web search", "known_fields": "query:React 19 new features explained"}
])

# Share explanation with team
mcp__rube__RUBE_MULTI_EXECUTE_TOOL(tools=[
    {"tool_slug": "NOTION_CREATE_PAGE", "arguments": {
        "title": "Understanding: React Concurrent Mode",
        "content": "## Overview\n..."
    }},
    {"tool_slug": "SLACK_SEND_MESSAGE", "arguments": {
        "channel": "#learning",
        "text": "New explainer: React Concurrent Mode fundamentals"
    }}
])

Flags (Extended)

Flag	Type	Default	Description
--pal-consensus	bool	false	Use PAL for multi-perspective validation
--pal-deep	bool	false	Use PAL thinkdeep for complex topics
--research	bool	false	Use Rube for web research
--share	string	-	Share via Rube (notion, slack, confluence)
