Update README

After any change to a skill's name, description, or directory, regenerate the Available Skills table by running the script below from the repo root:

bash update-readme/update-readme.sh

When to run

• After adding a new skill directory
• After editing the name or description field in any SKILL.md
• After renaming or deleting a skill directory

Script

Save as update-readme/update-readme.sh:

#!/usr/bin/env bash
# Regenerates the Available Skills table in README.md from SKILL.md frontmatters.
# Usage: bash update-readme/update-readme.sh
set -euo pipefail

ROOT="$(cd "$(dirname "${BASH_SOURCE[0]}")/.." && pwd)"
README="$ROOT/README.md"
