Matt Pocock, creator of Total TypeScript, publishes 39 MIT-licensed agent skills that make the AI interview you before it builds. They turn the answers into specs, tickets, tests and code. All 39 are installable from Cuttlefish.MD, HackerNoon's license-checked skills marketplace, and from Matt's own repo.
They follow the open Agent Skills standard, so they run in Claude Code, Codex CLI and 30+ other tools. Each is indexed in HackerNoon's SKILL.md Library. Some live in his repo's in-progress folder, so expect them to change.

Install them
Cuttlefish sorts skills by what they do, so Matt's 39 are spread across five category plugins. Most of them (29) are in Dev Workflow:
/plugin marketplace add hackernoon/cuttlefish-agent-skills
/plugin install dev-workflow@cuttlefish
/plugin install writing-blogging@cuttlefish
/plugin install learn-tech@cuttlefish
The remaining two are tdd in QA & Testing and codebase-design in Design & UI. For every Matt Pocock skill and nothing else, install straight from his repo. For Codex CLI or Cursor, copy the folders into your agent's skills directory, such as .agents/skills/.
Each skill keeps its MIT license and an ATTRIBUTION.md naming the source commit. Browse the full library at hackernoon.com/skills, and star Cuttlefish.MD on GitHub.
