Auto Luhmann Numberer Skill for Codex

自動魯曼編號機

Use this skill to manage stable writing-system addresses for book manuscripts and card boxes. Prefer the active book outline as the topic-number seed, then let Luhmann-style branches grow inside the outline without renumbering existing notes. When publishing the skill or sharing outputs, reduce real catalogs to a small public example.

Core Model

Use four separate namespaces:

• book_topic_code: pure numeric book addresses, at most five levels: 部、章、節、項、目. Examples: 1, 1.1, 1.1.3, 1.1.3.2.1.
• luhmann_branch_code: letter or mixed suffixes that grow from a book address. Examples: 1.1.a, 1.1.E, 1.1.c3b, 1.1.d.1.
• mandala_section_code: local Obsidian Mandala-Grid section comments inside one Markdown file. Examples: <!--section: 1-->, <!--section: 1.7-->, <!--section: 1.8.8-->.
• keyword_index_code: index-card ids such as K001, kept separate from topic codes.

Never merge these namespaces. A K001 card is not a chapter. A local section: 1.7 is not the book's 1.7 chapter unless the source explicitly says so.

Default Preferences

Read references/public-numbering-rules.json when you need the numbering taste, output schema, public-case policy, or Mandala section shape. The bundled example is intentionally minimal and safe to publish.

Important defaults:

• Use book chapter numbers as the ZKII-like topic seed.
• Preserve existing codes; do not renumber old cards just because a new card appears.
• Use letter branches such as 1.1.a to 1.1.g for lateral inserts under a chapter.
• Keep compact variants such as 1.1.c1, 1.1.c3a, and 1.1.c3b when they already exist.
• Treat letter-coded Markdown files with mandala: true or <!--section: ...--> markers as Mandala containers.
• Do not publish complete manuscript catalogs, absolute local paths, or private source titles unless the user explicitly asks for a private artifact.

Workflow

• Identify the source surface:
• Folder of Markdown files.
• Project-note JSON.
• HyperCard Markdown stack.
• EPUB catalog/build script.
• One new card that needs a code.

• Build or load a catalog:
• Use scripts/extract_book_codes.mjs <folder> to scan Markdown/TXT/JSON files and write a relative-path catalog.
• Use an existing catalog JSON if provided.
• Keep every entry's code, title, kind, source_path, depth, and any off_prefix_codes.

• Classify each code:
• Pure numeric code: 部/章/節/項/目 by dot depth.
• Code with letters: luhmann_branch.
• K###: keyword_index.
• <!--section: ...-->: local Mandala section.

• Validate:
• Flag missing chapter numbers, duplicate codes, codes deeper than five numeric levels, and off-prefix codes.
• Flag likely local Mandala sections so they do not pollute book-level numbering.
• Treat off-prefix codes as "待校正或跨章引用", not immediate errors.

• Assign a new code:
• If the note belongs to an existing pure numeric chapter, place it under the closest chapter.
• If it is a lateral insert, use a Luhmann branch suffix instead of renumbering neighbors.
• If it belongs inside a Mandala file, assign a display code like 1.1.E｜1.7.
• If it is an index concept, use the next K###.

• Explain the decision:
• Return the assigned code, code kind, parent code, previous/next neighbors, source assumption, and warnings.

Common Requests

• "Scan this folder and list every 部、章、節、項、目 code."
• "Find missing chapter numbers and off-prefix card ids."
• "Give this new note a Luhmann number without renumbering old cards."
• "Convert Mandala section addresses into display ids for HyperCard."
• "Prepare project-note JSON codes for EPUB export."

Output Shape

For a folder scan, produce both human and machine output when useful:

{
  "summary": {
    "chapters": ["1.1"],
    "missing": [],
    "warnings": []
  },
  "catalog": [
    {
      "code": "1.1.3",
      "title": "努力：先吃青蛙",
      "kind": "節",
      "source_path": "examples/1.1-fast-day-plan.md"
    }
  ]
}

For a single new card, return:

{
  "assigned_code": "1.1.E｜1.7",
  "code_kind": "mandala_section",
  "parent_code": "1.1.E",
  "section_code": "1.7",
  "reason": "The note belongs inside the existing Mandala branch file for non-linear numbering.",
  "warnings": []
}

Public Sharing Rule

Before making a repository public, remove or replace:

• Complete book catalogs that reveal the manuscript structure.
• Absolute local paths.
• Raw source excerpts or private chapter titles.
• EPUB files generated from private catalogs.

Keep only references/book-chapter-card-catalog.* as a public FAST day-plan example unless the user asks for a private build.
