Keshav Three-Pass Paper Reading Skill
Based on: S. Keshav, "How to Read a Paper" (ACM SIGCOMM 2007, updated 2013)
Purpose: Guide researchers through effective paper reading using three progressive passes, with AI assistance at each stage while preserving human judgment. Produces structured comprehension artifacts.
The Three-Pass Method
| Pass | Time | Focus | AI Role | Human Judgment Required |
|---|---|---|---|---|
| Pass 1 | 5–10 min | 5Cs: Category, Context, Correctness, Contributions, Clarity | Summarize RQ, contributions, conclusions | Decide: worth reading further? |
| Pass 2 | 30–60 min | Main thread, figures, experimental setup, key citations | Explain methods, figures, concepts | Cross-check: do numbers/claims match text? |
| Pass 3 | 1–2+ hrs | Deep reconstruction, assumptions, flaws, reproducibility | Play reviewer: probe assumptions, baselines, leaks | Decide: what to adopt/cite/build on? |
Structured Outputs (Generated After Pass 2 or 3)
The skill produces five standardized artifacts capturing comprehension:
| Artifact | Purpose | When Generated |
|---|---|---|
summary.md |
3–5 sentence executive summary | After Pass 2 |
problem.md |
Problem statement, motivation, gap | After Pass 2 |
method.md |
Core approach, algorithm, architecture | After Pass 2 |
results.md |
Key findings, numbers, tables, figures | After Pass 2 |
takeaways.md |
Actionable insights, limitations, future work | After Pass 3 |
Workflow
Prerequisites
- Paper accessible as text (
.txt,.md) or PDF (usepdftotextfirst) - Paper path or content provided
Pass 1: The 5Cs Scan (5–10 minutes)
Goal: Answer the 5Cs to decide whether to continue.
Read: Title, Abstract, Introduction, Section Headings, Conclusion, References.
AI Assistance Prompt:
You are a research assistant helping with Pass 1 of Keshav's three-pass method.
Paper text provided below. Extract and present:
1. CATEGORY: What type of paper? (survey, novel method, benchmark, position, theory, system, empirical study)
2. CONTEXT: Which field/subfield? Key prior works cited? Who is the audience?
3. CORRECTNESS: Do assumptions seem reasonable? Any red flags in claims?
4. CONTRIBUTIONS: What are the authors' stated contributions (usually in Introduction)?
5. CLARITY: How well-written? Accessible to non-specialists?
Output as a structured brief. DO NOT DECIDE for the user — just present the 5Cs.
Paper:
[paper_text_first_2000_chars_or_full_if_short]
Human Decision Point: Based on 5Cs, decide: Skip / Defer / Continue to Pass 2.
Record Decision: Save to pass1_decision.md with rationale.
Pass 2: The Main Thread (30–60 minutes)
Goal: Understand the paper's argument and evidence without getting lost in proofs.
Read: Full paper linearly, but skip proof details (appendices, derivations). Focus on:
- Figures and tables (what they show, trends, surprises)
- Experimental setup (datasets, baselines, metrics, hardware)
- Which key works are cited and how they're positioned
- The "story arc": problem → insight → method → results → implications
AI Assistance Prompt:
You are a research assistant helping with Pass 2 of Keshav's three-pass method.
Paper text provided below. Produce structured comprehension:
## SUMMARY (3-5 sentences)
Executive summary of the paper's core argument and findings.
## PROBLEM
- Core problem addressed
- Motivation / real-world impact
- Gap in prior work this paper fills
- Research questions or hypotheses
## METHOD
- Core insight / innovation (1-2 paragraphs)
- Algorithm / architecture / approach description
- Key design choices and why they matter
- Theoretical claims (if any)
## RESULTS
- Headline numbers (exact metrics from paper)
- Key figures/tables described with takeaways
- Baselines compared and outcomes
- Ablation studies (if any)
- Surprising or counterintuitive findings
## CITATIONS OF NOTE
- 3-5 most important prior works cited and how this paper relates to each
IMPORTANT: Cross-reference every number/claim against the provided text. Flag any discrepancies.
Paper:
[full_paper_text]
Human Verification: For each key number in Results, verify against original text. Do not trust AI extraction blindly.
Output Files Created:
summary.md— from SUMMARY sectionproblem.md— from PROBLEM sectionmethod.md— from METHOD sectionresults.md— from RESULTS section (with verified numbers)
Pass 3: Deep Reconstruction (1–2+ hours)
Goal: Reconstruct the author's thinking; scrutinize validity.
Activities:
- Could you reproduce the method from the description alone?
- Are assumptions valid? (data distribution, compute budget, task formulation)
- Do experiments support conclusions? (missing baselines, cherry-picked metrics, data leaks)
- Evaluation biases? (oracle choice, prompt sensitivity, seed variance)
- Overclaims? (generalization beyond evidence, "solves X" when only shows improvement on Y)
- What would you change / extend / challenge?
AI Assistance Prompt (Reviewer Mode):
You are a rigorous peer reviewer for this paper. Paper text and Pass 2 outputs provided.
Generate probing questions organized by category:
## ASSUMPTIONS
- What assumptions underlie the method? Are they explicit?
- What would break if assumption X is violated?
## EXPERIMENTAL DESIGN
- Are baselines appropriate and strong? Any missing?
- Is the evaluation metric aligned with the claimed contribution?
- Any data leakage risks (train/test overlap, oracle contamination)?
- Statistical rigor: seeds, variance, significance testing?
## CLAIMS VS EVIDENCE
- Which claims are well-supported? Which overreach?
- Does "we solve X" actually mean "we improve on benchmark Y by Z%"?
- External validity: do results generalize beyond the experimental setup?
## REPRODUCIBILITY
- Sufficient detail to reimplement? Missing hyperparameters?
- Compute requirements stated? Code/data availability?
## EXTENSIONS & FOLLOW-UPS
- What's the most natural next experiment?
- What would a strong ablation look like?
- How might this method fail in deployment?
Output as structured questions. Do NOT answer them — the human researcher answers.
Paper: [full_paper_text]
Pass 2 outputs: [summary.md, problem.md, method.md, results.md]
Human Synthesis: Answer the reviewer questions. Write takeaways.md with:
# Takeaways: [Paper Title]
## What I'll Use / Cite
- [Specific technique, insight, dataset, baseline]
## Limitations Noted
- [Assumption fragility, eval gap, scope restriction]
## Open Questions / Extensions
- [Concrete follow-up experiments or analyses]
## Verdict
- [Skip / Reference / Build Upon / Reproduce]
Usage Examples
Quick Start (All Passes)
User: "Read this paper with the three-pass method: /path/to/paper.txt"
Agent: Runs Pass 1 → presents 5Cs → user decides → Pass 2 → structured outputs → Pass 3 → takeaways
Specific Pass
User: "Just do Pass 1 on this paper"
Agent: Runs 5Cs scan only, saves pass1_decision.md
AI-Assisted Pass 2 on Existing Paper
User: "I've read the paper. Generate the 4 structured outputs from Pass 2."
Agent: Uses AI prompt with full paper text → produces summary.md, problem.md, method.md, results.md
Reviewer Mode (Pass 3 Only)
User: "Act as reviewer on this paper I've already read. Here are my Pass 2 notes."
Agent: Runs reviewer prompt → generates probing questions → user answers → takeaways.md
File Output Structure
paper_reading/
├── pass1_decision.md # 5Cs + continue/skip decision
├── summary.md # 3-5 sentence executive summary
├── problem.md # Problem, motivation, gap, RQs
├── method.md # Core approach, algorithm, design choices
├── results.md # Verified headline numbers, figures, ablations
└── takeaways.md # Personal synthesis: use, limits, extensions, verdict
Quality Standards
- Never fabricate numbers. Every metric in
results.mdmust trace to paper text. - Flag uncertainty. If paper is vague on a detail, state: "Paper does not specify X."
- Separate summary from judgment.
summary.md/problem.md/method.md/results.md= what the paper says.takeaways.md= what you think. - Cross-check Pass 2 extractions against original text before saving.
- Pass 3 questions are probes, not answers. The human provides answers in
takeaways.md.
Common Pitfalls
❌ Skipping Pass 1 — leads to wasting time on irrelevant papers
❌ Trusting AI extraction without verification — hallucinated numbers propagate
❌ Conflating summary with critique — keep results.md descriptive; save critique for takeaways.md
❌ Reading proofs in Pass 2 — saves them for Pass 3 (or skip entirely if not reproducing)
❌ Not making a Pass 1 decision — the 5Cs are useless without the continue/skip call
