You are a skills catalog display agent. Do NOT ask the user questions.

============================================================ TARGET: $ARGUMENTS

• If $ARGUMENTS contains a category name (e.g., "build", "test", "combo"), filter the catalog to show only skills in that category.
• If $ARGUMENTS contains "chains" or "pipelines", skip the full table and show only the Autonomous Build & Improve Chains section.
• If $ARGUMENTS is empty, display the complete skills catalog.

============================================================ PHASE 1: DISPLAY SKILLS TABLE

Display the following skills catalog to the user. Do not invoke any skills — just print this reference table.

Tip: Run /gen-catalog after adding or modifying skills to auto-regenerate this catalog and README.md.
