A prominent TypeScript educator has thrown his personal playbook for AI coding assistants onto GitHub — and the developer community is responding at scale. Matt Pocock, the creator of Total TypeScript, published his collection of 'skills': small, composable workflows he says he uses every day for real engineering, straight from his own .agents directory.
The repository shot to the top of GitHub's trending list, gathering roughly 2,700 stars in a single day. Its premise is deliberately contrarian: while popular agent frameworks such as GSD, BMAD and Spec-Kit try to help by 'owning the process', Pocock argues they take away control and make bugs in the process hard to resolve. His alternative is a set of adaptable, model-agnostic skills grounded in decades of engineering fundamentals — 'not vibe coding', as he puts it.
The skills read like a map of classic software engineering failure modes. Misalignment comes first: /grill-me and /grill-with-docs run 'grilling sessions' in which the agent interviews the developer about a plan until every branch is resolved — with /grill-with-docs also building a shared domain language in CONTEXT.md and ADRs, which Pocock calls 'possibly the single coolest technique in this repo'. For code that does not work, /tdd enforces a red-green-refactor loop, and /diagnosing-bugs wraps debugging into a disciplined, evidence-first loop. To stop codebases turning into balls of mud, /improve-codebase-architecture surveys a codebase for deepening opportunities, while /code-review runs a two-axis review (standards vs. spec) in parallel subagents. Further skills cover prototyping, research with cited sources, spec writing, ticket decomposition, and even /teach and /wizard for human-in-the-loop tasks.
Distribution mirrors a broader shift in the agent-tooling ecosystem. Claude Code users can install the whole set as a managed, read-only plugin from the official marketplace — 'subscribe rather than fork', with updates arriving automatically. Everyone else — Codex and other agents — can pull editable copies into their project via the skills installer (npx skills@latest add mattpocock/skills). Pocock explicitly warns against installing both paths, which leaves every skill duplicated.
The release is part of a wave of 'agent skills' repositories climbing GitHub Trending — including benchmark-driven projects promising to stop AI agents from over-engineering — signalling that developers are moving from raw prompts toward repeatable, versioned engineering practice for their AI pair programmers. Pocock's own summary is a one-liner: 'Software engineering fundamentals matter more than ever.'
