Issue / Context

Linked issue: N/A

Problem being solved:
This PR adds a dedicated skill for generating reviewer-friendly PR descriptions. Before this change, there wasn’t a canonical, reusable workflow in the skills repo for gathering diff context, commit history, impacted areas, and test signals before drafting a PR summary. The new skill gives agents a structured way to turn a code change into a clear, review-ready description instead of relying on ad hoc summaries.

Why This Matters

This skill turns PR writing from an improvised, variable-quality step into a repeatable workflow that reviewers can trust.

• Faster reviews: contributors get a structured summary up front, so reviewers spend less time reconstructing intent from the diff.
• Better decisions: the description calls out impacted areas, data flow, and testing signals, which makes risk easier to spot.
• Consistent documentation: every PR written with this skill follows the same shape, which keeps repository conventions predictable and easier to maintain.

Data Flow

Before:

User asks for a PR description
→ No dedicated skill workflow
→ Manual summarization or one-off prompt
→ Output quality varies by reviewer and context

After:

User asks for a PR description
→ Skill gathers diff, commits, linked issue, and test files
→ Skill analyzes impacted areas, data flow, and risk surface
→ Skill applies scoring rubric
→ Skill populates the PR template with a structured review-ready description

Testing Scenarios

List the scenarios a reviewer or QA should verify:

• The new pr-description-generator entry appears in README.md and is easy to discover.
• skills/pr-description-generator/SKILL.md clearly instructs the agent to gather diff, commit, issue, and test context before writing.
• references/pr-template.md includes all required sections and no placeholder text is left in the committed template.
• references/scoring-rubric.md provides clear, usable guidance for 1-10 scoring across the three dimensions.
• The packaged skills/pr-description-generator.zip contains the new skill content for distribution.
