The rising 2026 pattern
Spec-Driven Skills
Spec-driven development is the inverse of vibe-coding, write a clear specification first, then let the agent build to spec. AWS Kiro makes it native to the IDE; Claude Code, Cursor, Windsurf, and Antigravity 2.0 all support it via spec-driven skills.
Short answer
Spec-driven skills guide AI agents through a structured loop: read or write a specification, generate acceptance criteria, implement to spec, and verify the implementation matches the spec. The result is fewer rewrites, clearer acceptance, and reliable agent behavior on complex features.

Buildfrom Multi-Domain Skills11pptx
11 installsUse this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.

Analysis
Frequently asked questions
What is spec-driven development?
Spec-driven development means writing a clear specification (requirements, acceptance criteria, edge cases) before code. The AI agent reads the spec, implements to it, runs tests against the spec, and iterates until the spec is satisfied. It's the inverse of vibe-coding, structure first, then code.
Which AI tools support spec-driven development?
AWS Kiro makes spec-driven development native to the IDE. Claude Code, Cursor, Windsurf, and Antigravity 2.0 all support spec-first workflows via spec-writing skills from the skills-hub catalog, write a spec, hand it to the agent, iterate.
What's the difference between spec-driven and test-driven development (TDD)?
TDD writes tests first; spec-driven writes the full specification (requirements + acceptance criteria + edge cases + non-functional requirements) first. Tests are one artifact of a spec. Spec-driven is broader, it forces clarity about what 'done' means before any code is written.
How do spec-driven skills work?
A spec-driven skill is a SKILL.md file that guides the agent to: (1) read or write a spec, (2) generate acceptance criteria, (3) implement to spec, (4) verify against spec. Install one with npx @skills-hub-ai/cli install spec-driven-implement and use it in any compatible tool.
Are spec-driven skills portable across AI tools?
Yes, they follow the open Agent Skills standard (SKILL.md). The same spec-driven skill works in Kiro (where it's most native), Claude Code, Cursor, Windsurf, Antigravity 2.0, and any MCP-compatible tool.
Where do I learn more about spec-driven development?
Start with skills-hub's /spec skill, it generates structured specs from feature descriptions. Pair it with /mvp-spec for greenfield work, or /story-implementer to chain spec → implement → review → PR into a single agent team.
