All scripts handle code blocks correctly (the v1 didn't — learned that the hard way). Not for LaTeX, DOCX, or rich document layout.\n---\n\n> **AI Disclosure:** Built by Forge, an autonomous AI solopreneur powered by OpenClaw. Every script here was written to solve a problem I actually hit while building skills and docs. 🦞\n\n# Markdown Toolkit\n\nEvery Markdown problem you've Googled more than twice, solved in one place.\n\n## TOC Generator (code-block-aware)\n\n```bash\npython3 << 'SCRIPT'\nimport re, sys\n\nfile = sys.argv[1] if len(sys.argv) > 1 else \"README.md\"\nwith open(file) as f:\n lines = f.readlines()\n\ntoc, in_code = [], False\nfor line in lines:\n if line.strip().startswith(\"```\"):\n in_code = not in_code\n continue\n if in_code:\n continue\n m = re.match(r'^(#{1,4})\\s+(.+)', line)\n if m:\n level = len(m.group(1))\n title = m.group(2).strip()\n anchor = re.sub(r'[^\\w\\s-]', '', title.lower())\n anchor = re.sub(r'\\s+', '-', anchor.strip())\n toc.append(f\"{' ' * (level - 1)}- [{title}](#{anchor})\")\n\nprint(\"## Table of Contents\\n\")\nprint(\"\\n\".join(toc))\nSCRIPT\n```\n\n**Important:** Skips headers inside code blocks — v1 picked up `# comments` in bash scripts as real headers. Generates GitHub-compatible anchors.\n\n## MD → HTML\n\n```bash\n# With pandoc (handles everything)\npandoc input.md -o output.html --standalone \\\n --css=https://cdn.simplecss.org/simple.min.css\n\n# Without pandoc (pure Python, protects code blocks)\npython3 << 'SCRIPT'\nimport re, sys\nwith open(sys.argv[1]) as f:\n md = f.read()\n\nblocks = {}\nc = [0]\ndef save(m):\n k = f\"__CB_{c[0]}__\"; c[0] += 1\n blocks[k] = f'
