The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill directs the agent to fetch documentation from https://storybook.js.org/docs/releases/upgrading.md. This is the official documentation site for the Storybook project.
[REMOTE_CODE_EXECUTION]: The skill instructs the agent to run npx storybook@next upgrade. This command downloads and executes the Storybook CLI tool from the NPM registry at runtime.
[COMMAND_EXECUTION]: The skill instructs the agent to execute a shell command using npx to perform the upgrade process. This is a standard and expected operation for the vendor's own tooling.
[INDIRECT_PROMPT_INJECTION]: The agent is instructed to read external content from a web page in its entirety. This creates an attack surface where instructions embedded in the documentation could influence the agent's downstream actions.
