Standardize cross-skill invocation on explicit "call the Skill tool" phrasing Bare `/skill`-style prose ("run the `/grilling` skill") relies on the model reading a slash-prefixed name as a command to fire. Naming the tool directly gets a higher hit rate, and it's actually more harness-neutral than the old convention since it drops the Claude-Code-specific `/` trigger syntax entirely rather than assuming it. Updates the documented convention in .agents/invocation.md and every operative cross-skill invocation site in skills/**/SKILL.md to match. Co-Authored-By: Claude <noreply@anthropic.com>

What happened

The commit updated the documentation and invocation methods for the Skill tool in the skills repository. It replaced the old `/skill` invocation style with a more general phrasing for better performance.

Why it matters

This standardization could lead to increased reliability in skill invocation, improving developer workflows when integrating multiple skills in projects. By eliminating the reliance on specific syntax, it fosters a more flexible approach to skill usage across different AI models.
