stress-test

stress-test is a skill for Claude Code from ai-analyst-lab/ai-analyst-plugin. It costs 93 tokens per session (2,681 once invoked), scanned A, original, MIT.

A review guide that checks an analysis plan for methodological weaknesses before the work begins. It looks at issues such as biased samples, weak comparisons, missing groups, and confounding factors.

In plain words
What is it for?
Use it to review an investigation or data-analysis plan, its business context, intended audience, and criteria for stopping or changing the work.
Why use it?
It can reveal problems that would make an analysis misleading before time is spent executing it or presenting it.

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

stress-test 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.

Skill: Stress Test

Type: Standalone — reviews any analysis plan for methodological flaws


Purpose

Takes an analysis plan, investigation design, or analytical approach and pressure-tests it for hidden flaws — wrong baselines, survivorship bias, missing segments, uncontrolled confounds, and absent kill criteria. Acts as a "senior data scientist code review" for your analytical thinking.

This skill is standalone — it works on any analysis plan, whether produced by /analysis-design, written by the user, or pulled from an existing document.


When to Use

  • Before committing a week to executing an analysis plan
  • Before presenting an analysis design to stakeholders
  • When you've written an analysis brief and want a gut-check
  • When reviewing someone else's analytical approach
  • After an analysis came back with unexpected results (was the design flawed?)

Inputs

Input Required Source Description
{{PLAN}} Yes User or file path The analysis plan to review. Can be a file path, pasted text, or a description of the approach
{{CONTEXT}} No User Business context — what decision this analysis will inform
{{AUDIENCE}} No User Who will consume the results (affects what counts as "fatal" vs. "nice to have")
{{DATA_DESCRIPTION}} No User Description of available data, if not obvious from the plan

The 7-Point Stress Test

CRITICAL FIRST STEP: Check data availability BEFORE methodology review.

Before reviewing methodology quality, immediately verify that required data exists:

  1. Read the active dataset schema (.knowledge/datasets/{active}/schema.md)
  2. Check if the plan's required fields/tables/dimensions exist in the dataset
  3. If ANY required data is missing → HALT, skip checkpoints 1-6, jump straight to checkpoint 7, assign FAIL verdict with BLOCKER status, provide F grade, and stop
  4. If all required data exists → proceed with checkpoints 1-7 in order
