evidence-assessment
Evaluating the quality, provenance, and relevance of evidence that supports or undermines a claim. Covers source credibility, sampling quality, study design, levels of evidence (anecdote to meta-analysis), base rate integration, distinguishing primary from secondary sources, and calibrating belief to evidence strength. Use when the question is not whether an argument is valid but whether its premises are actually supported by the available data.

Same command for any agent — swap --agent for codex, cursor, copilot.

# Evidence Assessment Valid reasoning from false premises proves nothing. Evidence assessment is the discipline of testing whether the premises of an argument are actually supported by the data, what kind of data would be decisive, and how much confidence the available evidence warrants. This skill covers the evaluation of sources, study designs, sampling, levels of evidence, and the integration of new evidence with prior knowledge. **Agent affinity:** elder (structural reconstruction of evidence claims), tversky (base rates, inductive strength), kahneman-ct (evidence evaluation under System 1/2) **Concept IDs:** crit-evidence-quality, crit-sourcing, crit-burden-of-proof, crit-scientific-literacy ## The Assessment Toolbox at a Glance | # | Operation | Question answered | |---|---|---| | 1 | Source identification | Where did this claim come from? | | 2 | Primary vs. secondary | Is this the original source or a report of it? | | 3 | Source credibility | Does the source have relevant expertise and a track record? | | 4 | Funding and conflicts | Who paid for this?

What does the evidence-assessment skill do?
Evaluating the quality, provenance, and relevance of evidence that supports or undermines a claim. Covers source credibility, sampling quality, study design, levels of evidence (anecdote to meta-analysis), base rate integration, distinguishing primary from secondary sources, and calibrating belief to evidence strength. Use when the question is not whether an argument is valid but whether its premises are actually supported by the available data.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill evidence-assessment --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
