Routing Table Updater Skill

Overview

This skill maintains the /do routing indices when skills or agents are added, modified, or removed. It implements a Phase-Gated Pipeline -- scan, extract, generate, update, verify -- with deterministic script execution at each phase.

The skill reads metadata from all skills and agents (never modifies them) and validates and repairs the generated routing indices skills/INDEX.json and agents/INDEX.json. PostToolUse hooks (hooks/posttooluse-sync-skill-index.py, hooks/posttooluse-sync-agent-index.py) regenerate the indices automatically on every SKILL.md or agent-file edit; this skill covers drift those hooks miss (bulk changes, deletes outside the harness, corrupted index files).
