## Steps

1. [Read Contract Comparison Guide]: Read the documentation in: `./skills/sauna/[skill_id]/references/legal.contract.guide.md`

2. Gather the contracts to compare:

- Original/old version
- Revised/new version
- Context: Is this a negotiation? Internal revision? Annual renewal?
- Which party proposed the changes (if known)


3. Perform detailed comparison:

For each section of the contract, identify:

ADDITIONS
- New text that didn't exist before
- New clauses or provisions
- Expanded language

DELETIONS
- Text that was removed
- Clauses that were deleted
- Shortened provisions

MODIFICATIONS
- Text that was changed
- Original wording
- New wording
- Nature of change

Present changes in order they appear in the document.


4. Categorize and assess each change:

- Section/clause location
- Change type (add/delete/modify)
- Materiality (High/Medium/Low)
- Category (payment, liability, IP, etc.)
- Brief commentary on implication

Provide a count summary at the end.
