Claude Code Knowledge Base

Core Concepts

1. Hooks - Lifecycle event handlers

hooks:
  SessionStart: "Runs once when session starts"
  UserPromptSubmit: "Runs on every user message"
  PreToolUse: "Runs before tool execution"
  SubagentStart: "Runs when spawning subagent"
  Stop: "Runs when session ends"

2. Skills - Auto-activated contextual guidance

skills/
└── skill-name/
    └── SKILL.md  # YAML frontmatter + instructions

Skills activate automatically based on:
- User message content matching description
- Workflow phase detection
- Command execution context

3. Agents - Specialized subagents for tasks

agents/
└── agent-name.md  # Agent definition

Agents are invoked:
- Explicitly via Task tool
- Automatically via hooks/commands
- Through smart-agent-selector

4. MCP Servers - Model Context Protocol integrations

// ~/.claude/mcp.json
{
  "mcpServers": {
    "server-name": {
      "command": "npx",
      "args": ["-y", "@package/mcp-server"],
      "env": { "API_KEY": "${ENV_VAR}" }
    }
  }
}

Configuration Files

File	Purpose	Location
CLAUDE.md	Project instructions	Project root
~/.claude/settings.json	User settings	Home dir
~/.claude/mcp.json	MCP servers	Home dir
.claude-plugin/plugin.json	Plugin manifest	Plugin root
hooks/hooks.json	Hook configuration	Plugin root

Common Tasks

Creating a Hook

// hooks/hooks.json
{
  "hooks": {
    "UserPromptSubmit": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "${CLAUDE_PLUGIN_ROOT}/hooks/scripts/my-hook.sh",
            "timeout": 5000,
            "description": "My custom hook"
          }
        ]
      }
    ]
  }
}

Creating a Skill

#### Setting Up MCP Server

```bash
# 1. Add to ~/.claude/mcp.json
{
  "mcpServers": {
    "linear": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-linear"],
      "env": {
        "LINEAR_API_KEY": "${LINEAR_API_KEY}"
      }
    }
  }
}

# 2. Set environment variable
export LINEAR_API_KEY="lin_api_xxxxx"

# 3. Restart Claude Code

Research Patterns

When answering questions, this agent should:

1. Check embedded knowledge first (this file)
2. Search CCPM codebase for real examples
3. Fetch official docs via WebFetch if needed

// Research pattern
const answer = checkEmbeddedKnowledge(question);
if (!answer.confident) {
  const ccpmExamples = searchCcpmCodebase(question);
  if (!ccpmExamples.sufficient) {
    const officialDocs = await WebFetch('claude.ai/docs', question);
  }
}

## Integration with CCPM

This agent is invoked when Claude Code questions are detected:

```javascript
if (context.match(/\b(claude code|hook|skill|mcp|settings|cli|slash command)\b/i)) {
  Task({
    subagent_type: 'ccpm:claude-code-guide',
    prompt: `
## Question

${userQuestion}

## Context

- Project: ${project}
- Error: ${errorMessage || 'None'}

## Requested Format

${format}
`
  });
}

Examples

Example 1: Feature Explanation

Question: "What are hooks in Claude Code?"

Response:
## Hooks in Claude Code

**What they are:**
Hooks are lifecycle event handlers that run automatically at specific points during a Claude Code session.

**Available hooks:**
- SessionStart - Runs once when session starts
- UserPromptSubmit - Runs on every user message
- PreToolUse - Runs before each tool call
- SubagentStart - Runs when spawning subagent
- Stop - Runs when session ends

**Example hook configuration:**
```json
{
  "hooks": {
    "UserPromptSubmit": [{
      "hooks": [{
        "type": "command",
        "command": "./hooks/my-hook.sh"
      }]
    }]
  }
}

Use cases:

• Inject context automatically
• Validate operations
• Log activity
• Add safety checks

### Example 2: How-To Guide

Question: "How do I create a custom skill?"

Response:

Creating a Custom Skill

Step 1: Create skill directory

mkdir -p skills/my-skill

Step 2: Create SKILL.md with frontmatter

---
name: my-skill
description: >-
  What this skill does. Include trigger phrases
  like "widget creation" or "component building".
---

# My Skill

## When to Use
...

## Instructions
...

Step 3: Add supporting docs (optional)

mkdir skills/my-skill/supporting-docs
echo "# Reference" > skills/my-skill/supporting-docs/reference.md

Step 4: Test activation Say one of your trigger phrases to verify activation.

Common issues:

• Skill not activating → Check description includes trigger phrases
• YAML parse error → Validate frontmatter syntax

### Example 3: Troubleshooting

Question: "My MCP server isn't connecting"

Response:

MCP Server Connection Troubleshooting

Check 1: Verify configuration

cat ~/.claude/mcp.json

Check 2: Verify environment variables

echo $YOUR_API_KEY

Check 3: Test server manually

npx @your/mcp-server --version

Common issues:

Symptom	Cause	Fix
"Server not found"	Package name wrong	Check npm package name
"Unauthorized"	Missing API key	Set environment variable
"Connection refused"	Server not running	Restart Claude Code

If still failing:

1. Check Claude Code logs
2. Verify npm/Node.js is installed
3. Try reinstalling the MCP package
