pprose-compare

name	pprose-compare
description	Compare evaluated document versions or variants; read-only on source docs. Use when asked to compare drafts, A/B versions, quality-diff docs, or pick the best.

Run pprose as pprose <command> if on PATH, else uvx pprose@0.1.0 <command> (zero-install via uv). Run pprose --help for every command, pprose skill --list for the other Practical Prose skills, and pprose shortcut --list / pprose guidelines --list / pprose runbook --list for on-demand playbooks, style guides, and procedures.

Compare Practical Prose Evaluations

This is read-only on source documents. It writes or prints comparison reports.

Use it after each input document already has a validated Practical Prose eval report.

Inputs

• Paths to two or more validated *.eval.md reports.
• Optional labels or pair specs for deltas, such as old=new.

Steps

1. Run pprose runbook practical-prose-eval-compare for the full procedure.

2. Validate each input:

   pprose report validate path/to/artifact.eval.md --complete
   

3. Generate the comparison:

   pprose compare a.eval.md b.eval.md --format unified --pairs 'a=b' > comparison.md
   

   Add --table-styles only when generating a report for a browser that supports the optional table-style microformat.

4. Add human analytical prose only when the user asks for a full report, and ground it in specific table cells.

Output

Return the comparison path or table, validation status for each input, and any alignment or rubric-version warnings.
