Claude Code Analyzer

Claude Code History Analyzer

Complete workflow optimization for Claude Code through usage analysis, community discovery, and intelligent configuration generation.

Core Capabilities

This skill provides a complete Claude Code optimization workflow:

1. Usage Analysis - Extracts patterns from Claude Code history

• Tool usage frequency
• Auto-allowed tools vs actual usage
• Model distribution
• Project activity levels

2. GitHub Discovery - Finds community resources automatically

• Skills matching your tools
• Agents for your workflows
• Slash commands for common operations
• CLAUDE.md examples from similar projects

3. Project Analysis - Detects tech stack and suggests documentation

• Package manager and scripts
• Framework and testing setup
• Docker, CI/CD, TypeScript configuration
• Project-specific CLAUDE.md sections

4. On-Demand Documentation - Fetches latest Claude Code docs

• Agents/subagents structure and configuration
• Skills architecture and bundled resources
• Slash commands with MCP integration
• CLAUDE.md best practices from Anthropic teams
• Settings and environment variables

Complete Analysis Workflow

When user asks to optimize their Claude Code setup, follow this workflow:

Step 1: Run Usage Analysis

bash scripts/analyze.sh --current-project

This automatically:

• Extracts tool usage from JSONL files
• Checks auto-allowed tools configuration
• Analyzes model distribution
• Searches GitHub for community resources (always enabled)

Step 2: Run Project Analysis

bash scripts/analyze-claude-md.sh

This detects:

• Package manager (npm, pnpm, yarn, cargo, go, python)
• Framework (Next.js, React, Django, FastAPI, etc.)
• Testing setup (Vitest, Jest, pytest, etc.)
• CI/CD, Docker, TypeScript, linting configuration

Step 3: Interpret Combined Results

Combine insights from both analyses:

Usage patterns show:

• Tools used frequently but requiring approval → Add to auto-allows
• Auto-allowed tools never used → Remove from config
• Repetitive bash commands → Create slash commands
• Complex workflows → Create dedicated agents
• Domain-specific tasks → Build custom skills

GitHub discovery provides:

• Similar configurations from community
• Proven patterns for your tool usage
• Example agents/skills/commands to adapt

Project analysis reveals:

• Required CLAUDE.md sections
• Framework-specific conventions to document
• Testing and build commands to include

Step 4: Fetch Docs and Create Configurations

Based on recommendations, fetch latest docs and create:

For frequently used tools → Update auto-allows:

# Fetch settings docs
web_fetch: https://docs.claude.com/en/docs/claude-code/settings
# Update ~/.claude/settings.json

For repetitive commands → Create slash command:

# Fetch slash commands docs
web_fetch: https://docs.claude.com/en/docs/claude-code/slash-commands
# Create .claude/commands/[command-name].md

For complex workflows → Create agent:

# Fetch agents docs
web_fetch: https://docs.claude.com/en/docs/claude-code/sub-agents
# Create .claude/agents/[agent-name].md

For reusable domain knowledge → Build skill:

# Fetch skills docs
web_fetch: https://docs.claude.com/en/docs/agents-and-tools/agent-skills/overview
# Create .claude/skills/[skill-name]/SKILL.md

For project context → Write CLAUDE.md:

# Fetch CLAUDE.md best practices
web_fetch: https://www.anthropic.com/engineering/claude-code-best-practices
# Create .claude/CLAUDE.md with detected info

Example: Complete Optimization Session

User: "Help me optimize my Claude Code setup"

Claude executes:

1. Analyze usage patterns

   bash scripts/analyze.sh --current-project
   

   Finds: Bash tool used 150 times, Read 80 times, Write 45 times Auto-allows: None configured GitHub: Discovers community skills for TypeScript testing

2. Analyze project structure

   bash scripts/analyze-claude-md.sh
   

   Detects: Next.js project with Vitest, npm scripts: dev, build, test, lint Missing: CLAUDE.md doesn't exist

3. Make recommendations "I analyzed your Claude Code usage. Here's what I recommend:

   Auto-Allows: You use Bash (150×), Read (80×), and Write (45×) constantly. Let me add them to auto-allows.

   Slash Command: You run tests frequently. I'll create /test command.

   CLAUDE.md: Your Next.js project needs documentation. I'll create one with your npm scripts and testing setup.

   Community Resource: I found a TypeScript testing skill on GitHub that matches your workflow."

4. Fetch docs and create configs

   Fetch settings docs → Update ~/.claude/settings.json:

   {
     "autoAllowedTools": ["Bash", "Read", "Write"]
   }
   

   Fetch slash commands docs → Create .claude/commands/test.md:

   ---
   name: /test
   description: Run tests for current file or project
   allowed-tools: [Bash]
   ---
   Run tests: !npm test
   

   Fetch CLAUDE.md best practices → Create .claude/CLAUDE.md:

   # Project Context
   
   ## Commands
   - Dev: `npm run dev` (port 3000)
   - Build: `npm run build`
   - Test: `npm test`
   - Lint: `npm run lint`
   
   ## Tech Stack
   - Next.js 14
   - TypeScript
   - Vitest for testing
   
   ## Testing
   Run tests before commits: `npm test`
   

5. Share GitHub findings "I also found this community skill for TypeScript testing that you might find useful: [GitHub link]"

When to Use Each Tool

Use analyze.sh when:

• User asks to "analyze my workflow"
• Optimizing Claude Code setup
• Finding unused auto-allows
• Discovering community resources
• Understanding usage patterns

Use analyze-claude-md.sh when:

• Creating CLAUDE.md
• Setting up new project
• User asks "what should I document?"
• Need project-specific recommendations

Fetch docs when:

• Creating any configuration file
• User asks "how do I create an agent/skill/command?"
• Explaining configuration options
• Need current best practices

Use GitHub discovery for:

• Finding proven patterns
• Learning from community
• Getting configuration examples
• Discovering new approaches

Critical Documentation URLs

Always fetch latest docs before creating configurations:

Key Configuration Facts (from latest docs)

Agents (.md files with YAML frontmatter):

• Required: name, description
• Optional: tools (comma-separated), model (sonnet/opus/haiku/inherit)
• Location: .claude/agents/ (project) or ~/.claude/agents/ (user)
• NOT .yaml files!

Skills (directory with SKILL.md):

• Structure: skill-name/SKILL.md
• Bundled resources: scripts/, references/, assets/
• Progressive loading: metadata → instructions → resources
• Location: .claude/skills/

Slash Commands (.md files):

• Required: name (with / prefix)
• Arguments: $ARGUMENTS, $1, $2
• Optional: allowed-tools, model, argument-hint
• Location: .claude/commands/

CLAUDE.md (project documentation):

• Hierarchical: user-level → parent → project → nested
• Include: commands, style guidelines, testing, issues
• Keep concise and actionable
• Location: .claude/CLAUDE.md
