[Feature]: `playwright-cli install --skills` should support the `-g` flag

[linghengqian]

🚀 Feature Request

• playwright-cli install --skills should support the -g flag. I am referring to https://playwright.dev/agent-cli/skills . This parameter should install the skill into the ~/.agents/skills/ folder.
• Almost all agents support recognizing ~/.agents/skills/<name>/SKILL.md and ./.agents/skills/<name>/SKILL.md. For example, see https://opencode.ai/docs/skills/ .

Example

• Perhaps it can be executed in bash,

playwright-cli install --skills -g

Motivation

• If a user is maintaining a hundred projects simultaneously via opencode, there is obviously no need to run playwright-cli install --skills 100 times.
• Alternatively, it would be great if we could support using commands like npx skills add microsoft/playwright-cli --skill '*' --agent universal --yes --global via https://github.com/vercel-labs/skills .
