Get the Playbook
The Development Playbook is a free, open-source process framework for building apps from concept to post-launch. Six phases, 39 step guides, 22 templates, and real examples from 9 shipped projects. Clone it, fork it, make it yours.
6 Phases. 39 Guides. 22 Templates.
Each phase has step-by-step guides that tell you exactly what to do, blank templates you fill in for your project, and clear definitions of done so you know when to move on.
Vision, discovery, competitive analysis, feasibility
Requirements, architecture, design system, project plan
Sprint execution with 3-tier testing cadence
Functional, platform, performance, security, beta
Store prep, compliance, submission, launch day
Monitoring, feedback loops, iteration planning
Build Smarter, Not Just Faster
AI coding assistants are powerful but expensive. 99% of token cost is input, not output. The Playbook includes a complete token optimization guide with phase-specific strategies so you spend credits on building, not re-discovering context.
Context Architecture
Tiered CLAUDE.md structure that loads only what each session needs. Keep base context under 800 tokens.
Phase-Specific Tips
Each phase has a different token profile. Concept needs bounded exploration. Production needs prompt specificity. QA needs filtered output.
Anti-Pattern Detection
The most expensive mistakes are predictable. Vague prompts, re-reading files, unscoped test runs, stale context between tasks.
How to Use the Playbook
Clone or fork the repo
The Playbook lives on GitHub. Clone it into your project or fork it to customize the process for your team.
git clone https://github.com/gobixplr-svg/Playbook.gitStart at Phase 0: Concept
Open phase-0-concept/README.md. Read the overview, then work through each step guide in order. Fill in the templates as you go.
Follow the step guides
Each guide explains what to do, why it matters, what anti-patterns to avoid, and how to know when you're done. The templates give you a blank structure to fill in for your specific project.
Move through the phases
When you've completed a phase's deliverables, check the transition criteria in TRANSITIONS.md and move to the next phase. Each phase builds on the last.
