Three resources for readers who want to go deeper than the mini-site summary: the two briefs and the learning bundle.

FREE — NO FORM

SDD Practitioner Brief

For engineering leadership. Opens with the AI Productivity Paradox, then walks the architecture: two spec types (Feature Specs describe what to change; Anchor Specs describe how the system is), the pipeline and its gates, opposed review by design, and the proof discipline underneath every approval. Closes with the evidence from use. Edition 2, describing methodology v4.0.5.

PDF. No email required.

SDD Partner Brief

For CEOs and PE partners.

The capital-side read on Spec-Driven Development: why AI spend is not showing up in release cadence, and how that gap reads to a sponsor looking at a portfolio company’s engineering organisation.

SDD Learning Bundle

The kit itself, at v0.1.15: 26 agent definitions including the five SDD pipeline agents, 13 governance documents (Solo Operator Model, escalation rules, tier-selection guidelines, the two-architect gate, proof discipline, the seat-return contract and rule placement), the six gate checklists, 15 templates covering specs, anchors, escapes, learning events, review records and open questions — each with a worked example — plus 10 hooks and the skills, commands and bootstrap layers. For engineering leaders who want to run SDD on their own team.

ZIP, 114 files. Requested with a short form — we’d like to know which teams are running it.

The two briefs above download directly. The bundle is the kit itself, and we ask who is taking it — the methodology is open source under AGPL-3.0, so this is not a restriction on use. We want to know which teams are running it.

When you submit this form we collect your name, company, role and email address to send you the brief and to follow up. Delivery is handled by Resend, a US email provider; anti-spam by Cloudflare Turnstile. We don’t sell or share this information otherwise. A full privacy policy is being published; questions to grant@geekbyte.biz.

Apply This to a Portfolio Company.

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.
