paper-verification

paper-verification is a skill for Claude Code from fcakyon/phd-skills. It costs 67 tokens per session (1,052 once invoked), scanned A, original, MIT.

A method for checking whether a research paper’s claims match its code, data, formulas, citations, and experiment results. It traces reported numbers back to their source and checks that terminology and equations agree with the implementation.

In plain words
What is it for?
Use it to audit paper statistics, compare formulas with code, verify experiment results, check citation accuracy, and cross-check a manuscript before submission.
Why use it?
It helps find stale results, calculation errors, unsupported numbers, incorrect citations, and differences between described methods and actual code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

paper-verification scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Paper Verification Methodology

You are helping a researcher verify that their paper accurately reflects their code and experimental results. This is the most critical quality control step in academic writing.

Verification Dimensions

1. Numerical Accuracy Audit

For every number in the paper (dataset sizes, metric values, percentages, counts):

  1. Extract the number and its context from the .tex file
  2. Trace it to its source: code output, result file, log, or tracking system
  3. Verify the value matches exactly (watch for rounding, percentage vs decimal)
  4. Flag any number that cannot be traced to a source

Template:

| Paper claim | Location (.tex) | Source file/code | Source value | Match? |
|-------------|-----------------|-----------------|-------------|--------|
| "13,999 frames" | abstract L3 | len(glob(labels/*.json)) | ? | ? |
| "4.2% improvement" | Table 2 | eval_results.json | ? | ? |

Common numerical errors:

  • Rounding inconsistencies (3.14 in text, 3.1415 in table)
  • Stale numbers from earlier experiments not updated after re-runs
  • Percentage vs absolute confusion
  • Off-by-one in dataset counts (headers counted, or not)

2. Terminology Consistency Audit

  1. Extract all defined terms from the methods section
  2. Search for each term across ALL sections
  3. Flag any inconsistent usage:
    • Same concept, different names (e.g., "tag head" vs "classification head")
    • Same name, different meanings across sections
    • Defined but never used, or used but never defined

3. Code-Paper Alignment

For each method described in the paper:

  1. Find the corresponding code (function, class, module)
  2. Compare the paper's description with the actual implementation
  3. Check specifically:
    • Algorithm steps match code flow
    • Hyperparameters in text match config/code defaults
    • Architecture descriptions match model code
    • Loss functions in equations match loss code
    • Training procedures match training scripts

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

paper-verification is a skill published in the GitHub repository fcakyon/phd-skills (385 stars, last pushed 2mo ago), licensed MIT. It adds 67 tokens to every session and 1,052 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
