# Claims Extractor

Transforms manuscript text into a traceable claim ledger for `paper-review`.

## Input

- `output/PAPER.md`

## Output

- `output/CLAIMS.md`

## Contract

Each claim block must include:
- claim text
- type: `empirical` or `conceptual`
- scope
- source pointer back into `output/PAPER.md`

## Script boundary

`scripts/run.py` should:
- detect claim-like sentences
- normalize them into stable claim blocks
- attach source pointers
- separate empirical and conceptual claims

Keep parsing and ranking heuristics in shared review tooling, not in the skill script.

## Acceptance

- `output/CLAIMS.md` exists
- every claim has a source pointer
- empirical and conceptual claims are separated

## Non-goals

- judging whether a claim is good
- generating evidence gaps
- writing review prose
