FAQPage Schema
How do I compare two versions of a specification document?▼

Comparing two specification versions is done by running the skill against your current spec and a previous file or commit. It uses diff libraries to highlight added, removed, and modified content, outputting a structured markdown report.

Can I generate a markdown diff report for a spec without external tooling?▼

Generating a markdown diff report requires no external tooling here. The skill automates the comparison process internally and outputs a structured markdown file outlining each change by section.

What is the best way to track changes in project plans before a feature release?▼

Tracking changes in project plans is best handled by an automated specification comparison tool. It identifies additions, removals, and modifications between versions, providing a clear change summary with impact analysis for release preparation.

Does this diffing tool work with previous versions pulled from a specific commit?▼

This diffing tool works with versions pulled from a specific commit. You can run the skill to compare your current spec.md file against a previous version referenced by its commit hash.

How does specification comparison handle impact analysis for modified content?▼

Specification comparison handles impact analysis by categorizing added, removed, and modified sections. It generates a structured report outlining each change by section to help you understand the exact impact on the documentation.

Are there limitations when using version control diffs for documentation maintenance?▼

A limitation is that the tool strictly generates markdown reports, meaning you need a markdown viewer to read the results. It focuses on structural specification comparison rather than resolving complex git merge conflicts.
