PaperSpine — Motivation-Driven Paper Writing Skill Suite for Codex and Claude Code

PaperSpine — Motivation-Driven Paper Writing Skill Suite for Codex and Claude Code

A manuscript construction skill suite (GitHub: WUBING2023/PaperSpine, ~240 stars as of May 2026, created May 2026) that runs inside Codex ($paper-spine) and Claude Code (/paperspine). Its defining feature: it refuses to start writing until a confirmed_motivation.md exists. Every section, every claim, and every revision is traced back to that central motivation — producing a writing rationale matrix that documents not just what each section says but why it belongs in the paper at all.

What Problem It Solves

Most AI writing tools start from a prompt: “write me an introduction for a paper about X.” PaperSpine treats this as the wrong starting point. A paper isn’t a collection of sections — it’s an argument, and an argument has a spine. Without confirmed motivation, individual sections can be well-written while the paper as a whole fails to cohere.

The toolkit enforces a motivation-first discipline:

Confirm motivation → Research SOTA → Build evidence bank
→ Section blueprint → Writing rationale matrix
→ Draft section by section → Revision audit trail
→ Final output (LaTeX + .bib, optional DOCX, optional PDF, optional CN translation)

Every artifact in the pipeline answers to the central motivation. If a section can’t be justified against the motivation, the rationale matrix exposes it before the writing happens.

Two First-Class Workflows

Workflow 1: Rewrite Existing You have a manuscript — a draft, a rejected submission, a course report that needs journal quality. PaperSpine audits the existing structure against the motivation it extracts, identifies what to restructure or cut, and rebuilds with a rationale matrix that documents every change.

Workflow 2: Build From Materials You have notes, figures, data summaries, partial drafts, PDFs — but no finished manuscript. PaperSpine assembles the paper from raw inputs, confirming motivation first, then constructing the evidence bank before a word of the main text is written.

Both workflows produce the same artifact set at the end. The difference is the starting point.

The Central Artifact: Writing Rationale Matrix

The writing_rationale_matrix.md is PaperSpine’s signature output and the thing that distinguishes it from general-purpose writing assistants:

Column What it records
Section Which part of the paper (Introduction, Methods, etc.)
Unit purpose What this section does for the argument
Motivation link How it serves the confirmed central motivation
SOTA lessons What was learned from the example papers that informed this section’s approach
Evidence support Which items from the evidence bank underpin the claims here
Text checks Specific checks the draft must pass (no unsupported claims, venue tone match, etc.)

This matrix is the audit trail. A coauthor, advisor, or reviewer can read it and immediately see whether the paper is arguing coherently or drifting. It is also the primary input for revision: when a reviewer asks you to reframe the contribution, you update the matrix first, then the text.

Research Phase: Flash vs. Pro

Before any writing, PaperSpine runs a structured literature survey:

Mode Papers surveyed Use when
flash 3 SOTA examples + 3 recent papers Time-limited; quick positioning
pro 6 SOTA examples + 6 recent papers Full submission; want deep venue calibration

The output feeds directly into the evidence bank and informs which claims the rationale matrix will flag as requiring citation.

Evidence Bank and Claim Register

No claim enters the draft without a corresponding entry in the claim register. The claim register tracks:

  • The claim itself
  • The evidence bank item(s) that support it
  • The section where it appears
  • Whether it has been verified against a fetched or provided source

This is the structural answer to hallucination: not a prompt that says “only make claims you can support,” but an artifact that makes unsupported claims visible before submission.

Output Formats

Format Notes
main.tex + .bib Always produced; journal/conference-ready LaTeX
.docx Optional; for advisors or coauthors who don’t use LaTeX
PDF Optional; compiled from LaTeX
Chinese translation package Optional; full CN translation of the finished paper

Installation and Invocation

Codex:

$paper-spine

Bundled skill in dist/codex/paper-spine/. Available after plugin install.

Claude Code:

/paperspine

Flat skill suite in dist/claude/. Install via:

/plugin marketplace add https://github.com/WUBING2023/PaperSpine
/plugin install paper-spine
/reload-plugins

Both environments run the same underlying workflow; the invocation surface adapts to the tool.

How It Differs from academic-research-skills (Imbad0202)

These are complementary academic writing suites, not overlapping:

Dimension academic-research-skills (Imbad0202) PaperSpine (WUBING2023)
Primary focus Research workflow — finding, organizing, synthesizing literature Manuscript construction — writing, rationale, revision
Entry point A research question A motivation or existing draft
Signature mechanism Socratic intent detection + PRISMA systematic review Writing rationale matrix + claim register
Review simulation Yes (EIC + 3 reviewers + Devil’s Advocate) No
LaTeX output Yes (via academic-paper skill) Yes (core output)
Evidence tracking Via systematic review pipeline Via evidence bank + claim register
Best for Researchers who need to master the literature before writing Writers who have the material and need to construct the argument

The ideal pipeline for a serious paper: use academic-research-skills to master the literature, then hand the evidence to PaperSpine to construct the manuscript.

How LearnAI Team Could Use This

  • Paper writing module for grad students — PaperSpine’s motivation-first discipline maps directly onto the advice faculty give in every thesis seminar. Teaching it as a skill puts a structure around advice that is usually informal (“make sure your paper has a clear argument”).
  • Undergraduate writing quality — Use the rationale matrix as a grading scaffold: does each section justify its existence against the paper’s central claim? Students who use PaperSpine will naturally produce papers that answer this question.
  • Research methods courses — The evidence bank + claim register is a practical implementation of the “every claim needs a citation” rule. Assign it as infrastructure, not just as a style guide.
  • Academic integrity framing — PaperSpine is a strong example of AI-augmented writing that keeps the researcher in the epistemic loop. The model drafts; the human controls the motivation, verifies the evidence, and owns the argument. Use it to demonstrate responsible AI use in research.
  • Conference/journal submission preparation — The flash vs. pro research modes map onto time constraints real researchers face. A short workshop paper can run flash; a journal submission should run pro.

Real-World Use Cases

Scenario How to use
Rejected manuscript revision Use “Rewrite Existing” workflow; the rationale matrix will surface structural problems a reviewer reacted to but couldn’t articulate
PhD thesis chapter Confirm motivation at the chapter level; use the matrix to ensure the chapter argument is coherent before drafting 20,000 words
Conference deadline crunch Run “flash” research mode; limit the claim register to the 5–7 claims the paper absolutely must make; draft to the matrix
Collaborative paper with international coauthors The rationale matrix serves as a shared document all coauthors can read and challenge before writing begins, reducing revision cycles
Course research paper (undergraduate) Lower the bar: use it with 2 SOTA + 2 recent papers; the claim register teaches citation discipline as a workflow, not just a rule
Multi-language submission Use the Chinese translation package for papers targeting Chinese venues without a separate translation step

Important Things to Know

  • Very new. Created May 17, 2026 — ~240 stars (as of May 2026) in days, which means the workflow is less battle-tested than academic-research-skills (which has 18K+ stars). Expect rough edges.
  • Motivation-first is non-negotiable. The skill won’t bypass the confirmed_motivation.md step. This is by design. If a student or researcher finds this frustrating, that frustration is itself a signal worth examining.
  • The claim register does not fetch sources for you. It tracks claims and their evidence pointers; you still need to supply the actual papers or use academic-research-skills to surface them.
  • LaTeX is the primary output. The DOCX option exists but is secondary. Teams that live in Word or Google Docs should pair this with a LaTeX-to-DOCX conversion step.
  • No peer review simulation. Unlike Imbad0202’s suite, PaperSpine does not simulate reviewer feedback. Run the finished manuscript through academic-research-skills’ academic-paper-reviewer if you want a pre-submission review pass.
