Claude Launcher

Interactive system prompt and model selector for Claude Code.

Start Claude with your chosen persona and model in seconds:

# Interactive 2-step selection (persona → model)
$ cl

# Direct shortcuts (order-independent)
$ cl tdd opus        # Super TDD Developer + Opus
$ cl opt sonn        # Claude Code Optimizer + Sonnet
$ cl haik            # Generalist Robot + Haiku (default persona + model)

# Model-only (uses generalist-robot)
$ cl sonn
$ cl opus

Features:

• Order-independent shortcuts: cl tdd sonn = cl sonn tdd
• Frontmatter-based shortcuts (add your own personas instantly)
• Automatic skill loading via @ references
• Conflict detection with prominent warnings
• Exports CLAUDE_PERSONA for status line display

Setup:

alias cl='python3 /path/to/claude-skillz/claude-launcher/claude-launcher.py'

# Optional: Install fzf for interactive fuzzy search
brew install fzf  # macOS

See available personas below. You can add your own.

Available Skills

Skills are reusable behavioral instructions loaded into personas. Load them with @ references in your system prompts.

Research & Evidence

• independent-research - Research-driven investigation. Never guess—validate solutions before presenting. Use WebFetch, WebSearch, testing.
• confidence-honesty - Force honest confidence assessment. Express confidence as percentage, explain gaps, validate assumptions before presenting.

Communication & Output

• concise-output - Signal-over-noise. Eliminate verbose phrases, prioritize density. Every word must carry information.
• critical-peer-personality - Professional, skeptical communication. Challenge constructively, propose instead of asking, coach rather than serve.
• questions-are-not-instructions - Answer questions literally. Don't interpret as hidden instructions. STOP after answering, let user decide.

Code & Design

• software-design-principles - Object calisthenics, dependency inversion, fail-fast error handling, feature envy detection, intention-revealing naming.
• lightweight-implementation-analysis-protocol - Trace execution paths before implementing. Create lightweight diagrams. Prevent wasted effort from assumptions.
• lightweight-design-analysis - Systematic design review across 8 dimensions: Naming, Object Calisthenics, Coupling & Cohesion, Immutability, Domain Integrity, Type System, Simplicity, Performance.

Development Processes

• tdd-process - Strict TDD state machine: red-green-refactor with 11 enforced rules. Meaningful failures, minimum implementations, full verification.
• writing-tests - Principles for effective tests. Naming conventions, assertion best practices, comprehensive edge case checklists (based on BugMagnet).
• observability-first-debugging - Systematic debugging. Add instrumentation to gather specific data. Evidence before hypothesis.

Workflows & Tools

• switch-persona - Mid-conversation persona switching without restart. Lists personas, reads file, switches immediately.
• lightweight-task-workflow - Task list state machine for multi-session work. Tracks status, prevents auto-advancement, enforces state transitions.
• create-tasks - Convert requirements into actionable tasks following a structured template. Engineering-ready work items.

Specialized

• data-visualization - Build charts, graphs, dashboards. Visual execution, technical implementation, perceptual foundations, chart selection, layout algorithms, library guidance.
• typescript-backend-project-setup - NX monorepo setup for TypeScript backend projects optimized for AI-assisted development.
