What causes "Installation cancelled" in upstash/context7?

Re-run and select skills, or use `--all` to install every skill in the repo without the prompt.

Installation cancelled

Error message

Installation cancelled

What it means

The catch block around the skill multi-select prompt shown when installing from a repository that has more than one skill and neither --all was passed nor only one skill existed. @inquirer checkbox prompts throw ExitPromptError on Ctrl+C/Esc; the CLI maps any throw to 'Installation cancelled' and returns without installing.

Solutions

Re-run and select skills, or use `--all` to install every skill in the repo without the prompt.
Name the skill directly: `context7 skill add <repo> <skill>` bypasses the multi-select.
Ensure an interactive TTY when you want the selection UI.

Defensive patterns

Strategy: try-catch

Validate before calling

if (!process.stdin.isTTY) {
  console.error("Interactive skill selection requires a TTY; pass --all or name the skill explicitly.");
  process.exit(1);
}

Type guard

function isPromptAbort(err: unknown): boolean {
  return err instanceof Error && err.name === "ExitPromptError";
}

Try / catch

try {
  selectedSkills = await checkbox<Skill>({ message: "Select skills", choices });
} catch (err) {
  if (isPromptAbort(err)) {
    log.warn("Installation cancelled");
    return;
  }
  throw err;
}

Prevention

Use --all or `skill add <repo> <name>` to avoid the multi-select entirely.
Only catch ExitPromptError; rethrow other errors so render bugs are visible.
Check for a TTY before showing checkbox prompts.

When it happens

Trigger: Pressing Ctrl+C or Esc at the 'select skills to install' checkbox; an empty checkbox submission is handled separately ('No skills selected'), so this warning specifically means the prompt threw.

Common situations: User browses a repo's skills then bails; non-interactive shell where the checkbox prompt cannot render; accidental Esc during selection.
