My skills

Task

Scan all installed skills and plugins, then display a formatted catalog to the user.

Method: Single-Pass Scan

Run ONE bash command that scans everything at once. This avoids 15+ sequential tool calls and completes in seconds.

Step 1: Run the scan script

Execute this bash command. It scans all marketplaces, plugins, and custom commands in a single pass and outputs structured text:

MARKET_DIR="$HOME/.claude/plugins/marketplaces"
SETTINGS="$HOME/.claude/settings.json"
PROJ_DIR="$(pwd)/.claude/commands"
SEPARATOR="|||"

extract_frontmatter() {
  local file="$1" field="$2"
  sed -n '/^---$/,/^---$/{ /^'"$field"':/{ s/^'"$field"': *//; s/^"//; s/"$//; p; } }' "$file" 2>/dev/null | head -1
}

extract_json_field() {
  local file="$1" field="$2"
  sed -n 's/.*"'"$field"'": *"\([^"]*\)".*/\1/p' "$file" 2>/dev/null | head -1
}

# --- Skills from marketplaces ---

seen_skills=$(mktemp)
trap "rm -f '$seen_skills'" EXIT

add_skill() {
  local sname="$1" sfile="$2" source="$3"
  grep -qxF "$sname" "$seen_skills" 2>/dev/null && return
  local desc=$(extract_frontmatter "$sfile" "description")
  [ -z "$desc" ] && desc="(no description)"
  echo "$sname" >> "$seen_skills"
  skills="${skills}${sname}${SEPARATOR}/${sname}${SEPARATOR}${desc}${SEPARATOR}${source}\n"
}

  done
fi

# --- Output ---
echo "===SKILLS==="
echo -e "$skills"
echo "===PLUGIN_COMMANDS==="
echo -e "$plugin_cmds"
echo "===BG_PLUGINS==="
echo -e "$bg_plugins"
echo "===CUSTOM==="
echo -e "$custom"

Step 2: Parse and display

The script outputs sections separated by ===SECTION_NAME=== markers. Each line within a section uses ||| as the field separator.

Parse the output and display a formatted catalog with these sections:

Important Notes

• Do NOT modify any files. This is a read-only operation.
• Show ALL results, not just a summary.
• If the list is very long, still show everything — the user wants a complete picture.
• The entire scan should complete in ONE bash call. Do not make additional file reads.
• Truncate long descriptions to ~100 characters in the table for readability.
