PR Description Format (Based on PR #10-14 Analysis)

Opening Paragraph (1-2 sentences)

•
Must include: Concise description of core changes
•
Should include: Key metrics or numbers (test count, coverage %, file count, version numbers)
•
Example (PR #14):

This PR implements comprehensive test coverage (440 tests, 97.52% statement coverage) across unit, component, and E2E layers. Adds GitHub Actions CI/CD pipeline and complete testing documentation.
•
Example (PR #13):

This PR refactors the color management system to use semantic naming conventions (textPrimary, bgPrimary, themePrimary) and improves UI interactions across components. It includes date validation logic, unified element sizing, and default item improvements.

Fixed Heading: "Key changes:" (Required)

After the summary paragraph, must use Key changes: as the section heading (note colon and capitalization).

Section Structure (Select by Priority)

Universal Sections (Most PRs)

•

Components / UI:

•List all Vue component changes, UI adjustments, interaction improvements
•Format: - Verb-led description

•Example:

code

- Implement a 200ms delay for drag-and-drop on touch devices
- Increase touch targets for buttons, checkboxes, and menu items to 44px
- Add ARIA labels and roles for screen reader compatibility

•

Logic & persistence:

•List logic changes, state management, data persistence

•Example:

code

- Implement bidirectional date protection: changing start date updates end date if end < start
- Add scrollIntoView logic when entering edit mode to prevent keyboard occlusion
- Prevent premature saving when users are selecting characters via IME

•

Documentation:

•List documentation updates (docs/ directory, README, product specs)
•Format: - Update/Add <filename>: <brief description>

•Example:

code

- Update product-spec.md with new color system documentation and date editing logic
- Add docs/testing-guide.md: complete test inventory, architecture, conventions

Topic-Specific Sections (Select as Needed)

•
Test Infrastructure (Testing PRs)
- •List test tools, frameworks, configuration files
- •Include version numbers and specific file names
- •
  Example:
  code
  - Vitest 4.0.18 + @vue/test-utils 2.4.6 for unit/component testing - tests/test-setup/setup.js: global mocks (localStorage, crypto, scrollIntoView)
•
Component Test Suite (N tests) (If component tests exist)
- •Mark test count in parentheses
- •One line per component, format: - <ComponentName> (<count> tests): <test scope>
- •
  Example:
  code
  - App (42 tests): initialization, state management, event coordination - Checklist (36 tests): CRUD operations, date validation, overflow menu

•

Unit Test Suite (N tests) (If unit tests exist)

•Similar to component test format

•Example:

code

- localStorageService (100 tests): CRUD, caching, cross-tab sync, concurrency
- helpers (21 tests): secure ID generation, date formatting, debounce

•

E2E Test Suite (N tests) (If E2E tests exist)

•List test files and test focus

•Example:

code

- mobile-workflow (9 tests): sidebar overlay, hamburger menu at 375px
- item-packing (7 tests): category management, progress tracking

•

CI/CD Pipeline (If CI changes exist)

•List workflow files and execution steps

•Example:

code

- GitHub Actions workflow: lint → unit test → E2E test → build
- Husky pre-commit hook with lint-staged

•
Configuration (If config file changes exist)
- •List new or modified configuration files
- •Format: - <filename>: <purpose or change>
- •
  Example:
  code
  - playwright.config.js: Chromium browser, screenshot on failure - package.json scripts: test:run, test:e2e, test:coverage

•

Build & Configuration (If build-related changes exist)

•List build process, bundling configuration changes

•Example:

code

- Refactor THEME_COLORS in constants.js from SCREAMING_SNAKE_CASE to camelCase
- Update build-css-vars.js to generate CSS variables with simplified naming

Writing Standards (Mandatory)

Bullet Point Format

•Prefix: Use - (hyphen) + space
•Verb: Start with present tense verbs (Add, Update, Implement, Support, Ensure, Refactor)
•Length: Single line, concise but include key details
•
Technical terms:
- •File names use full relative paths (e.g. tests/test-setup/setup.js)
- •Tools/packages include version numbers (e.g. Vitest 4.0.18)
- •Numbers must be precise (e.g. 440 tests, 97.52% coverage)

Section Order (Recommended)

•Topic-specific sections (Test Infrastructure, Component Test Suite, etc.)
•Components / UI:
•Logic & persistence:
•CI/CD Pipeline (if present)
•Configuration (if present)
•Build & Configuration (if present)
•Documentation:

Tone and Style

•Technical, direct, no fluff
•Describe "what was done", not "why"
•Use active voice (Add X, not X is added)
•English primary (unless citing non-English proper nouns)

Execution Workflow

•

Auto-collect information:

bash

git log main..HEAD --oneline --no-merges
git diff main...HEAD --stat
git diff main...HEAD --name-only

•
Classify file changes:
- •source/components/*.vue → Components / UI
- •tests/**/*.test.js → Component/Unit Test Suite
- •tests/**/*.spec.js → E2E Test Suite
- •*.config.js, package.json → Configuration
- •docs/*.md → Documentation
- •.github/workflows/*.yml → CI/CD Pipeline
•
Calculate key metrics (if applicable):
- •Test file count and test case count
- •Number of new/modified components
- •Package version numbers (from package.json)
- •File change statistics (git diff --stat)
•
Generate PR title:
- •Determine primary change type (test/feat/fix/etc.)
- •Write concise description focusing on impact
- •Add issue number if referenced in commits
•
Generate PR description:
- •First paragraph: summary + key metrics
- •Key changes: followed by sections
- •Each section filled with bullet points based on actual diff output only
- •CRITICAL: Do NOT extract bullet points from commit messages - analyze file diffs directly
- •Ensure format matches PR #10-14 exactly
•
Output format:
- •Title: First line, format type: description (#issue)
- •Blank line
- •Description: Pure Markdown body (can paste directly into GitHub PR)
- •No ```markdown markers (output content directly)

Critical Rules (Mandatory)

•Never fabricate data: All numbers, version numbers, file names must come from actual git diff or package.json
•Use diff output ONLY: Bullet points describe actual file changes from git diff analysis - NEVER extract descriptions from commit messages (commit messages may describe intermediate states that don't exist in final diff)
•Maintain format consistency: Strictly follow PR #10-14 format (capitalization, punctuation, section order)
•Dynamic section adjustment: Select sections based on actual changes, don't force all sections
•Technical details first: Prioritize specific technical implementation (file names, function names, version numbers) over abstract descriptions
•If information insufficient: Clearly indicate what additional information is needed (e.g., "Please provide the issue number this PR resolves")
