pr-description-generator（公关描述生成器）

PR Description Generator

Auto-generate structured PR descriptions from git diffs and commit history. Pure Python + git CLI.

Quick Start

# Standard description (current branch vs main)
python3 scripts/generate_pr_description.py

# Compare against specific base branch
python3 scripts/generate_pr_description.py --base develop

# Minimal template (just bullet points)
python3 scripts/generate_pr_description.py --template minimal

# Detailed template (file breakdown + reviewer hints)
python3 scripts/generate_pr_description.py --template detailed

# JSON output (for automation)
python3 scripts/generate_pr_description.py --format json

# Different repo path
python3 scripts/generate_pr_description.py --repo /path/to/repo

# Save to file
python3 scripts/generate_pr_description.py --output pr-body.md

# Copy to clipboard
python3 scripts/generate_pr_description.py --copy

Features

• Conventional commit parsing — groups commits by type (feat, fix, refactor, etc.)
• Impact analysis — rates changes as high/medium/low based on files, size, and risk
• File categorization — groups by code, tests, docs, infra, deps, config, database, styles
• Reviewer hints — warns about missing tests, DB migrations, infra changes, deletions
• Auto test plan — generates relevant test checklist based on changed file types
• Auto base detection — detects main vs master branch

Templates

Conventional Commits

Best results when commits follow conventional format:

feat(auth): add OAuth2 login
fix(api): handle null response from payment gateway
refactor: extract validation into shared utility
docs: update API reference for v2 endpoints

Non-conventional commits are grouped under "Other Changes".
