research-methodology

research-methodology is a skill for Claude Code from poemswe/co-researcher. It costs 48 tokens per session (982 once invoked), scanned A, original, MIT.

A guide for choosing research methods based on the question being asked, the sample being studied, and the controls needed to judge validity. It covers methods such as surveys, experiments, interviews, and case studies.

In plain words
What is it for?
Use it to classify research questions, choose study designs and sampling strategies, check research quality, and reframe difficult research problems.
Why use it?
It helps avoid using a research design that cannot properly answer the question or support trustworthy conclusions.

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

research-methodology 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 12d 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.

Descriptive Prevalence, Patterns Survey, Observational
Comparative Differences, Improvement Experimental, Quasi-exp
Relational Association, Prediction Correlational, Regression
Causal Effect, Impact RCT, Quasi-experimental
Mechanism How does, Why Qualitative, Mixed

2. Design Specializations

  • Quantitative: RCTs, Quasi-experimental, Surveys, Longitudinal.

  • Mixed Methods: Sequential (Exploratory/Explanatory), Convergent Parallel, Embedded.

3. Validity & Quality Control

  • Quantitative Quality: Power analysis (N size), randomization, blinding, ITT analysis, manipulation validity (a pilot shows the manipulated condition triggers the mechanism under test).
  • Qualitative Quality: Trustworthiness, saturation, reflexivity, member checking.
  • Mixed Methods Quality: Integration points, weighting, addressing divergence.

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.
