Create a skills repo for installing useful skills for our CLI and SDKs that you can load into popular coding agents

Background:

• https://code.claude.com/docs/en/skills
• https://platform.claude.com/docs/en/agents-and-tools/agent-skills/best-practices
• https://agentskills.io/home
• https://github.com/ComposioHQ/awesome-claude-skills

Goal:

• Make it easy to supercharge local coding agents with knowledge to get to work using the kernel CLI and SDKs quickly

Prior art:

• https://github.com/railwayapp/railway-skills
  • things i like:
    • curl install to get it into any coding agent
    • good example of how to make a skill for a cli
• https://github.com/expo/skills
  • things i like:
    • has use-case oriented plugins you can install, e.g. I could see us creating a skill around building a browser agent, etc. (out of scope for this ticket but something to keep in mind)

Desired flow in Claude Code:

• /plugin marketplace add kernel/skills
• /plugin install kernel-cli -> installs Kernel CLI skill
• /plugin install kernel-sdks -> installs SDK skills (can break out ts and python into subdirectory references/ files for progressive disclosure)

Desired flow for other coding agents:

• curl some kernel.sh url that redirects to a raw github URL e.g. curl -fsSL https://www.kernel.sh/skills | bash and set up a redirect at that url to something like https://raw.githubusercontent.com/kernel/skills/main/install.sh

Some acceptacne tests:

• once the CLI skill is installed, asking Claude to do something like "spin up a browser and test navigating to kernel.sh and taking a screenshot" should immediately lead to the exactly correct kernel CLI usage:
  • kernel browsers create … -o json
  • kernel browsers playwright execute …
  • kernel browsers screenshot …
• Similarly for the SDK skill, if a query is made like "build a playwright script in typescript that spins up a remote browser and …" should immediately churn out a correct script using onkernel/sdk without having to run any web searches / doc searches etc.
