sync-translations

Keeps the docs/ko/ Korean translations synchronized with the English source documents in docs/en/.

When to Use

User says "sync docs", "update translations", "sync translations", "번역 동기화", "mirror docs"
After a batch of documentation updates where Korean translations may be missing
Periodically to audit translation completeness across the project

Directories in Scope

English source	Korean translation
`docs/en/specifications/`	`docs/ko/specifications/`
`docs/en/issue/`	`docs/ko/issue/`
`docs/en/policy/`	`docs/ko/policy/`

docs/reference/ is excluded — user-managed, language-neutral, no translations needed.

Step-by-Step Instructions

Step 1: Audit — Find Missing Translations

List all English source files in the three directories:

find docs/en/specifications docs/en/issue docs/en/policy \
  -name "*.md" ! -name ".gitkeep" 2>/dev/null | sort

For each file found (e.g., docs/en/issue/issue003.md), check whether the corresponding translation exists (e.g., docs/ko/issue/issue003.md).

Build a Missing list of files with no Korean translation.

Step 2: Audit — Find Stale Translations

For files where a Korean translation exists, compare modification times using git:

git log --follow -1 --format="%ai" -- docs/en/issue/issue003.md
git log --follow -1 --format="%ai" -- docs/ko/issue/issue003.md

If the English source has a more recent commit than the Korean translation, add it to a Stale list.

Step 3: Report and Confirm

Tell the user:

Sync audit complete:

Missing translations ( files):

docs/en/issue/issue004.md

docs/en/specifications/architecture.md

Potentially stale ( files):

docs/en/policy/policy.md (English updated 2025-11-01, Korean updated 2025-10-15)

Shall I create/update all of them?

Wait for confirmation before writing any files.

Step 4: Create or Update Translations

For each file in the Missing or Stale lists:

Read the English source file completely
Translate all prose content into Korean
Write the file to the corresponding docs/ko/ path with the same filename

Naming rule: Replace docs/en/ with docs/ko/ (same filename):

docs/en/issue/issue003.md → docs/ko/issue/issue003.md
docs/en/specifications/requirements.md → docs/ko/specifications/requirements.md
docs/en/policy/commit-message-rule.md → docs/ko/policy/commit-message-rule.md

Step 5: Report Results

List every file created or updated with their paths.

Translation Rules

Translate to Korean:

All prose paragraphs and sentences
Section headings
List item descriptions
Table cell text

Keep in English:

Code blocks (...) — never translate the content inside
File paths (docs/en/issue/issue001.md)
Function names, variable names, class names
Branch names and command-line examples
Technical acronyms: API, URL, HTTP, JSON, Git, etc.
Checkbox markers: - [ ], - [x]

For technical acronyms on first use, optionally add a brief Korean explanation in parentheses, then use the acronym alone thereafter.

Preserve markdown structure exactly:

Same heading levels (#, ##, ###)
Same list and checkbox formatting
Same bold/italic markers
Same horizontal rules and table structure
