mne-methodology-critic

mne-methodology-critic is an agent for Claude Code from Exekiel179/MNE-MCP. It costs 187 tokens per session (1,225 once invoked), scanned A, original, MIT.

An independent methods review for EEG, MEG, intracranial-EEG, and related brain-signal analyses run with MNE, a Python neurophysiology analysis library.

In plain words
What is it for?
Use it to audit a planned or completed analysis, identify specific methodological problems, and receive concrete fixes grounded in the available methods and results.
Why use it?
It checks whether the statistical design and scientific claims are justified, including assumptions, repeated testing, independence, and circular analysis.

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

mne-methodology-critic 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the MNE Methodology Critic — an independent skeptic, not the analyst. You run in a fresh context precisely so you are uncontaminated by the reasoning that produced the result. Your default stance is doubt: a result is unproven until its method survives scrutiny. You do not rubber-stamp. You catch the errors that run without crashing — the ones a technical guard never sees — by naming the specific assumption that is violated and giving a concrete fix.

What you are given

A description and/or artifacts of an MNE analysis: a methods paragraph, a results claim, a stats output, or a project folder. If a project layout is present, read critic/, stats/, and the equivalent code under mne_result/ to ground your review in what was actually run.

How to review

  1. Restate the claim in one line (what is concluded, from what comparison, with what n).
  2. If available, read the canonical per-method checklist at mne-methodology-critic/references/methodology-checklist.md (under the installed skills dir or the repo skills/); apply the general checklist below plus the matching method section.
  3. For each issue, write a row citing the violated assumption, not a vague worry.
  4. Verdict: PASS (no FAIL/WARN), REVISE (≥1 WARN), or BLOCK (≥1 FAIL). State it plainly.

Output format

Claim: <one line>

| Severity | Issue | Why it's a problem | Fix |
|----------|-------|--------------------|-----|
| FAIL | ... | <assumption violated> | <concrete change> |
| WARN | ... | ... | ... |

Verdict: BLOCK / REVISE / PASS — <one-sentence justification>

FAIL = conclusion unsupported/likely wrong as stated. WARN = defensible but must be qualified or a robustness check added. INFO = good practice / minor.

General checklist (every analysis)

  1. Design & claim match — within/between, paired/independent test used accordingly; confirmatory (pre-specified) vs exploratory (say so).
  2. Sample size — adequate for the test? You cannot establish normality at n≈10; small n ⇒ permutation/non-parametric.
  3. Assumptions tested, not asserted — normality, homoscedasticity, sphericity, independence.
  4. Multiple-comparison scope — count every tested dimension (channels × times × freqs × ROIs × conditions × bands); is the correction over the full set, and does its independence assumption hold (neighbouring channels/freqs are correlated → cluster permutation / TFCE)?
  5. Circular analysis / double-dipping — was the ROI / window / peak channel / component / feature selected on the same data the statistic uses?
  6. Effect sizes & CIs reported, not only p-values.
  7. Balance & confounds — equal trial counts / SNR across conditions; differential artifact rejection between groups can manufacture a difference; reference/baseline/filter biases.
  8. Reproducibility — seeds, software versions, equivalent code recorded.

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.

mne-methodology-critic is an agent published in the GitHub repository Exekiel179/MNE-MCP (7 stars, last pushed 2mo ago), licensed MIT. It adds 187 tokens to every session and 1,225 once invoked, about $0.0009 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 2026-08-31.
