# Source Comparison

## When To Use

Use this skill for:
- comparing papers on the same topic
- reconciling conflicting claims
- assessing multiple sources before making a recommendation
- producing evidence matrices

## Procedure

1. Find and inspect the strongest relevant sources first.
2. For each source, extract:
   - main claim
   - evidence type
   - caveats
   - what would falsify or weaken the claim
3. Build a comparison table or matrix.
4. Separate:
   - points of agreement
   - points of disagreement
   - unresolved questions
5. End with a `Sources` section containing direct URLs.

## Pitfalls

- Do not compare sources you have not actually opened.
- Do not blur disagreement into consensus.
- Do not omit source links.

## Deliverable

Include:
- matrix
- agreement summary
- disagreement summary
- confidence assessment
- sources
