AI Coding Tools

A collection of configurations, prompts, and tools that I use to enhance my AI-assisted development workflow.

Claude Code Configurations

Custom configurations for Claude Code.

Status Line

Custom status line that provides real-time context awareness and project visibility.

Features

The custom status line provides at-a-glance information about your development session:

• Project name - Current working directory
• Git status - Branch name and working tree state (clean ✓ or dirty ●)
• Model information - Currently active Claude model (Sonnet 4, Opus, etc.)
• Context usage - Token usage with intelligent buffer calculations and color-coded warnings

The status line uses color coding to communicate state:

• Green git indicator = clean working tree
• Red git indicator = uncommitted changes
• Gray context indicator = normal usage (<90%)
• Yellow context indicator = approaching auto-compact (90-94%)
• Red context indicator = auto-compact imminent (≥95%)

Installation

1. Copy settings configuration:

   cp claude/settings.json ~/.claude/settings.json

Note: Ensure that the "command" path in claude/settings.json matches the location where you'll install statusline-command.sh.

1. Install the status line script:

   cp claude/statusline-command.sh ~/.claude/statusline-command.sh
   chmod +x ~/.claude/statusline-command.sh

2. Restart Claude Code to apply the new configuration.

How It Works

settings.json

• Enables the custom status line command (ensure that the path to the statusline-command.sh is correct)
• Activates extended thinking mode for better reasoning

statusline-command.sh

• Parses Claude Code's session data (workspace, model, transcript)
• Calculates real-time context usage from the transcript JSONL file
• Includes a 22.5% auto-compact buffer to match /context command behavior
• Renders a powerline-style status bar with ANSI color codes
• Integrates git status checking for branch and working tree state

The context calculation accounts for:

• Input tokens
• Cache read tokens
• Cache creation tokens
• Auto-compact buffer (~45k tokens for 200k limit)

This gives you an accurate representation of when Claude Code will trigger auto-compact, helping you manage context proactively.

Curated prompts and reference documents for AI-assisted development.

Design Principles

File: prompts/design/design_principles.md

A comprehensive reference document covering fundamental design and accessibility principles for building high-quality software interfaces.

What's Included

This document consolidates four essential frameworks:

1. Dieter Rams' 10 Principles of Good Design

   • Originally for physical products, adapted for software
   • Emphasizes innovation, utility, aesthetics, clarity, and minimalism
   • Includes practices, watch-outs, and team checklists

2. Ben Shneiderman's Eight Golden Rules of Interface Design

   • Focus on consistency, shortcuts, feedback, and error handling
   • Practical heuristics for design reviews
   • Instrumentation and quality gate recommendations

3. Nielsen's 10 Usability Heuristics

   • System visibility, user control, error prevention
   • Recognition over recall, flexibility and efficiency
   • Includes design review checklists and metrics guidance

4. WCAG 2.0 Accessibility Guidelines

   • POUR principles (Perceivable, Operable, Understandable, Robust)
   • AA conformance targets with concrete examples
   • Engineering-friendly acceptance criteria and testing strategies
