# Claude Code Developer Tools
|
|
|
|
> **Generated via Web-Enhanced Infinite Agentic Loop**
|
|
> 8 progressive self-contained tools for Claude Code observability, search, and coordination
|
|
|
|
## Overview
|
|
|
|
This collection demonstrates the **web-enhanced infinite agentic loop** pattern, where each tool iteration:
|
|
1. Fetches web documentation using WebFetch
|
|
2. Learns 2-3 specific techniques from the source
|
|
3. Applies those techniques to build a production-quality developer tool
|
|
4. Builds upon patterns from previous iterations
|
|
|
|
**Total Generated**: 8 tools (258KB)
|
|
**Pattern**: Foundation → Intermediate → Advanced → Expert
|
|
**Approach**: Progressive web learning with parallel agent coordination
|

|
## 🚀 Usage
|
|
|
|
### Opening Tools
|
|
Each tool is self-contained. Simply open any `.html` file in a modern browser:
|
|
|
|
```bash
|
|
# Open in default browser
|
|
xdg-open claude_devtool_1.html
|
|
|
|
# Or use specific browser
|
|
firefox claude_devtool_1.html
|
|
chrome claude_devtool_1.html
|
|
```
|
|
|
|
### Loading Transcript Data
|
|
Claude Code transcripts are stored at: `~/.claude/projects/[project-id]/transcript.jsonl`
|
|
|
|
1. Navigate to a project directory
|
|
2. Copy or load the `transcript.jsonl` file
|
|
3. Use Tool 1 to load and view
|
|
4. Use Tool 2 to cache for quick access
|
|
5. Use Tools 3-8 for analysis and visualization
|
|
|
|
### Recommended Workflow
|
|
1. **Tool 1**: Load transcripts initially
|
|
2. **Tool 2**: Cache important sessions
|
|
3. **Tool 3**: Visualize timeline
|
|
4. **Tool 7**: Analyze productivity metrics
|
|
5. **Tool 6 or 8**: Search for specific patterns
|
|

## 🎨 Design Philosophy
|
|
|
|
### Developer-First
|
|
- **Dark Theme**: Easy on eyes during long coding sessions
|
|
- **Monospace Fonts**: Code-friendly typography
|
|
- **Keyboard Shortcuts**: Power-user navigation
|
|
- **Performance**: Fast load, responsive interactions
|
|
|
|
### Self-Contained
|
|
- **Zero External Dependencies**: All CSS/JS inline (except D3 CDN)
|
|
- **Offline Capable**: Works without internet after initial load
|
|
- **Browser Storage**: Leverage localStorage, no backend needed
|
|
- **Progressive Enhancement**: Basic functionality without advanced features
|
|
|
|
### Web-Enhanced
|
|
- **Real Web Sources**: Every tool learned from actual MDN/D3 documentation
|
|
- **Documented Learning**: Each tool cites its source URL
|
|
- **Applied Techniques**: Specific patterns demonstrated in code
|
|
- **Progressive Difficulty**: Foundation → Intermediate → Advanced → Expert
