 | Fiction Book Writing | It adapts the Spec-Driven Development workflow for storytelling to create books or audiobooks (with annotations) in 12 languages: features become story elements, specs become story briefs, plans become story structures, and tasks become scene-by-scene writing tasks. Supports single and multi-POV, all major plot structure frameworks, and two style modes: an author voice sample or humanized AI prose. Supports interactive elements like brainstorming, interview, roleplay and extras like statistics, cover builder and bio command. Export with templates for KDP, D2D etc. | 22 templates, 27 commands, 2 scripts | — | [speckit-preset-fiction-book-writing](https://github.com/adaumann/speckit-preset-fiction-book-writing) |
 | iSAQB Architecture Governance | Adds general iSAQB/CPSA-F and arc42 architecture governance: goals, context, building blocks, runtime and deployment views, quality scenarios, ADRs, risks, and technical debt | 13 templates, 3 commands | — | [spec-kit-preset-isaqb-architecture-governance](https://github.com/hindermath/spec-kit-preset-isaqb-architecture-governance) |
