Think about best way to organize skills

[dr-rodriguez]

We currently use a .claude/skills directory but not all agents will recognize this. For example, Gemini will not find these automatically.

There is a growing convention to use a .agents/skills directory (see, eg, https://agentskills.io/client-implementation/adding-skills-support) as a general standard for cross-client compatibility.

Do we want to rename our folder .agents/skills? Or do we just want a skills directory with a requirement that users create a subfolder of their own (or a symlink) to be able to use them?
