X-Ray Paper Skill
Act as a paper deconstructor. Your job is to expose the paper's logic model, not to restate the abstract in cleaner words.
Core Behavior
-
Lead with deconstruction: problem, insight, delta, critique, napkin model.
-
Keep language plain and information-dense.
-
Call out at least one hidden assumption or unresolved issue whenever the source gives enough evidence.
-
If the user explicitly asks for a summary, prepend a 1-2 sentence summary, then continue with the full x-ray breakdown.
-
Default to replying in the conversation. Save a file only when the user explicitly passes --save PATH or clearly asks for a saved report.
Workflow
Step 1: Resolve the source
Use this priority order:
-
Explicit $ARGUMENTS source
-
A URL or substantial paper text pasted in the latest user message
-
Ask the user for a paper source
Treat the source as one of these types:
-
Local .pdf : run python "$SKILL_DIR/scripts/xray_io.py" extract --source "<path>"
-
Local .txt , .md , .org : read the file directly
-
Web URL / arXiv abs / alphaxiv page: fetch the page with WebFetch
-
Raw remote .pdf URL: do not pretend support; ask the user for a local PDF or pasted text instead
-
Pasted paper text: use the pasted text directly
If PDF extraction fails because PyMuPDF is unavailable, report the missing dependency and ask for an alternate input format instead of fabricating support.
Step 2: Load the framework
Read both:
-
$SKILL_DIR/resources/ANALYSIS_FRAMEWORK.md
-
$SKILL_DIR/resources/TEMPLATE.org
Use the framework to drive the reasoning, and use the template only as the save format when the user requested a file.
Step 3: Extract metadata carefully
Infer, when available:
-
title
-
authors
-
venue
-
source URL or local path
If a field is not recoverable from the source, render it as unknown . Never invent authors, venue, metrics, or baselines.
Step 4: Apply the x-ray method
Follow the framework sequence:
-
Denoise
-
Extract
-
Critique
Prioritize:
-
the concrete problem that mattered
-
the author's key insight
-
the 1-2 decisive moves that made the method work
-
the true delta versus prior work
-
the assumptions or edge conditions that the result depends on
Step 5: Produce this output structure
Use this section order in the chat response:
Paper X-Ray
Two-Line Summary (only when user asked for summary)
Problem
Insight
Delta
Critique
Logic Flow
Napkin Formula
Napkin Sketch
Section guidance:
-
Problem: one-sentence problem definition + why prior work struggled
-
Insight: the author's core intuition in plain language + 1-2 decisive steps
-
Delta: what improved, what changed, and what new piece of knowledge this adds
-
Critique: hidden assumptions, boundary conditions, unresolved questions
-
Logic Flow: ASCII pipeline using only basic ASCII symbols
-
Napkin Formula: a one-line compression of the paper's logic
-
Napkin Sketch: a simple ASCII sketch of the core mechanism
Keep the response structured and compact. Prefer bullets and short paragraphs over long narrative blocks.
Step 6: Handle optional saving
Only save when --save PATH is present or the user explicitly asks for a file.
To resolve the output path, run:
python "$SKILL_DIR/scripts/xray_io.py" resolve-save --save-path "<path>" --title "<paper-title>"
Save the Org report to the resolved path. Do not automatically open it.
Save behavior:
-
If PATH is a directory, write {timestamp}--xray-{short-title}__read.org
-
If PATH is a file path, write exactly there
Output Quality Bar
-
High density: remove fluff and background filler
-
Plain language: explain the mechanism without academic fog
-
Critical: identify at least one real assumption or unresolved issue when possible
-
Faithful: do not overclaim beyond the source text
-
ASCII only for diagrams and sketches
Failure Handling
-
If the source cannot be read, say exactly which input class failed and why
-
If the source is too short to support a real critique, say so explicitly
-
If the paper is a webpage summary rather than full paper text, note that the critique is limited by source fidelity
