SKILL.md

Code & Concept Explanation Skill

Educational explanations with adaptive depth and format.

Quick Start

bash
# 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

  • educator - Learning-optimized explanations
  • architect - System design context
  • security - 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

bash
# 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

bash
# 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)

Advanced (--level advanced)

  • Deep technical details
  • Edge cases and trade-offs
  • Performance implications

Format Options

Text (--format text)

  • Written explanations
  • Step-by-step breakdowns
  • Conceptual overviews

Examples (--format examples)

  • Code samples
  • Before/after comparisons
  • Real-world applications

Interactive (--format interactive)

  • Follow-up suggestions
  • Exploration paths

Examples

Code Explanation

/sc:explain src/auth/jwt.js --level basic
# What the code does, how it works, why it's structured this way

Framework Concept

/sc:explain useEffect --level intermediate --context react
# Hook lifecycle, dependency arrays, cleanup patterns

Architecture Explanation

/sc:explain event-driven-architecture --level advanced
# Patterns, trade-offs, implementation strategies

Security Concept
