Skill 冗余审计员

触发场景

• 用户说“检查/清理/优化 Skill 冗余”或类似意图。
• 自动化任务过多，需要排查重复/暂停任务。
• 新增大量 Skill 后，定期做路由归一化。

工作流程

1. 全量扫描

# 统计 Skill 总数（含子命令）
python3 - <<'PY'
from pathlib import Path
root = Path('~/.workbuddy/skills')
files = [f for f in root.rglob('SKILL.md') if 'node_modules' not in f.parts]
print(len(files))
PY

# 提取每个 SKILL.md 的标题、摘要、触发词（需要 PyYAML）
~/.workbuddy/binaries/python/envs/default/bin/python - <<'PY'
import re, yaml, json
from pathlib import Path
root = Path('~/.workbuddy/skills')
records = []
for f in sorted(root.rglob('SKILL.md')):
    if 'node_modules' in f.parts:
        continue
    text = f.read_text(encoding='utf-8', errors='ignore')
    m = re.match(r'^---\s*\n(.*?)\n---\s*\n', text, re.DOTALL)
    meta, body = {}, text
    if m:
        try:
            meta = yaml.safe_load(m.group(1)) or {}

        body = text[m.end():]
    title = meta.get('title') or meta.get('name') or ''
    if not title:

        title = hm.group(1).strip() if hm else f.parent.name
