Quaestor is a Claude Code plugin that provides Skills and slash commands for specification-driven development. Write lightweight specs, implement with context, ship with confidence.

**Design Principles:**

• Zen - Minimal surface area, maximum utility
• Engineer as Driver - You make decisions, Quaestor provides structure
• Light Spec-Driven - Just enough specification to stay aligned

**_NOTE:_** Quaestor has been many things, but mainly a learning sandbox for me. Nowadays, it's a tool that I and a small number of people use. From 1.0 forward, Quaestor will be boring and stable. New features will be planned and added as Anthropic releases new features for Claude Code. This is all to say that Quaestor is "feature complete," and hardly any skills, sub-agents, or commands will be added. I've gotta get back to work, and so do you.

What's Included

**7 Skills** (auto-activate based on context):

• managing-specifications - Create and manage specifications
• implementing-features - Implement features with quality gates
• reviewing-and-shipping - Code review and PR generation
• debugging-issues - Systematic bug investigation
• security-auditing - Security analysis and vulnerability detection
• optimizing-performance - Performance profiling and optimization
• initializing-project - Setup Quaestor in any project

**3 Slash Commands:**

• /plan - Create specifications
• /implement - Implement specs with tracking
• /research - Explore codebase patterns

**Spec Lifecycle:**

• Folder-based state: draft/ → active/ → completed/
• Automatic progress tracking via checkboxes
• Max 3 active specs (enforced)
