Two resources for readers who want to go deeper than the mini-site summary: the executive brief and the learning bundle.
The SDD Executive Brief
A PDF introducing Spec-Driven Development for PE firms and portfolio engineering teams. Opens with the AI Productivity Paradox, then walks the v4.0 architecture: two spec types (Feature Specs describe what to change; Anchor Specs describe how the system is), the four-gate pipeline, and the coach that installs alongside Claude Code. Closes with field evidence from the alpha kit.
Get the BriefThe SDD Learning Bundle
A deeper archive for practitioners: the five SDD pipeline agent prompts, governance documents (Solo Operator Model, escalation protocols, tier-selection guidelines, stack quirks), the four gate checklists (spec, arch, qa, deploy), and worked learning artifacts from real GeekByte specs (catches, escapes, and process gaps). For engineering leaders who want to run SDD on their own team.

The brief and the bundle are how engineering leaders evaluate SDD before adopting it. In a portfolio engagement, GeekByte sits with the CTO through the adoption window — past evaluation, into the team. If you’re considering SDD for a portfolio company, the conversation is the place to start.
