Portable TanStack Start React Server Components skill for Codex, Claude Code, Cursor, and other AI coding agents.

TanStack Start RSC Skill

Portable skill for TanStack Start React Server Components.

This repo is the skill folder itself. That is intentional. It means people can use it however they already work:

• install it with npx skills
• symlink or copy it into a local Claude Code or Codex skills directory
• zip it and upload it to Cursor
• hand the repo or zip to another agent and tell it to install it

The skill is built for real TanStack Start RSC work, not for reciting docs:

• primitive choice: renderServerComponent vs createCompositeComponent vs low-level Flight APIs
• cache ownership: Router vs Query vs HTTP/server cache
• refresh wiring: router.invalidate() vs Query invalidation vs HTTP revalidation
• Composite Components and slot design
• SSR mode selection, loader boundaries, and stale API cleanup

The fast answer

Do I need to connect this repo to skills.sh?

No.

If this repo is on GitHub, people can install it directly with npx skills add <owner>/<repo>. The Skills CLI accepts GitHub shorthand, full GitHub URLs, direct paths inside repos, and local paths. skills.sh is the public discovery directory for the ecosystem, but it is not required for installation.

Does this repo already work with npx skills?

Yes.

The CLI looks for valid SKILL.md files in the repo root as well as common skill directories. This repo keeps SKILL.md at the root, so npx skills add CodingCossack/tanstack-start-rsc-skill is enough once the repo is published.

Pick the install path that matches how you work

Important distinction:

• global means global for a specific agent, such as Claude Code or Codex
• there is no single universal skill directory shared by every harness
• if you want one command that installs globally across multiple supported agents, use npx skills and target those agents explicitly
