Kordoc Detect Format

kordoc: detect_format

Reproduce the detect_format logic from src/mcp.ts: read only the header, then call detectFormat.

Input Requirements

• Require exactly one target file.
• Require the user to attach the file or provide a concrete local path.
• Prefer supported document candidates: .hwp, .hwpx, .pdf.
• Do not proceed if the file is missing.

Command

npm exec --yes --package=kordoc --package=pdfjs-dist -- node  d.endsWith(".bin"));
const kUrl = "file:///" + p.join(p.resolve(nmBin, ".."), "kordoc", "dist", "index.js").split(p.sep).join("/");
import(kUrl).then(k => {
  const filePath = "/abs/path/document.hwpx";
  const fd = fs.openSync(filePath, "r");
  const header = Buffer.alloc(4);
  try { fs.readSync(fd, header, 0, 4, 0); } finally { fs.closeSync(fd); }
  const ab = header.buffer.slice(header.byteOffset, header.byteOffset + header.byteLength);
  console.log(k.detectFormat(ab));
}).catch(e => { console.error(e); process.exit(1); });
SCRIPT

Workflow

1. Resolve the file to an absolute path.
2. Read only the first 4 bytes (the magic bytes detectFormat inspects).
3. Return only hwp, hwpx, pdf, or unknown.
4. If the type is supported, move to the matching kordoc skill.

Guardrails

• Do not infer type from the filename alone.
• If the result is unknown, stop and report that rather than trying to parse anyway.
• Keep the answer short unless the user asked for diagnostics.
• Refuse to continue when no file was provided.
