Context

!ls readme.*.md 2>/dev/null || echo "No readme translations" !ls .github/contributing.*.md 2>/dev/null || echo "No contributing translations" ![ -f repomatic/__init__.py ] && echo "CANONICAL_REPO" || echo "DOWNSTREAM" ![ -d repomatic/data/awesome_template ] && echo "HAS_AWESOME_TEMPLATE" || echo "NO_AWESOME_TEMPLATE"

Instructions

You synchronize translated markdown files with their English sources. The translation workflow in these repositories is documented in contributing.md § Pull-requests and issues: contributors propagate changes to all readme.*.md files using automatic translation tools, and bilingual contributors refine the result later.

This skill automates the detection side: find what drifted, show the delta, and draft updated translations for the stale sections.

Scope

In downstream awesome-* repos: Sync readme.*.md files against readme.md.

In the repomatic canonical repo: Sync contributing.*.md against contributing.md inside repomatic/data/awesome_template/.github/. The awesome-template is the source of truth for contributing guides synced to all downstream repos, so keeping its translations current benefits every downstream project.

Argument handling

• $ARGUMENTS can be a language code (e.g., zh, fr, ja) to limit the sync to one language. If empty, process all *.{lang}.md translation files found.

Step 1: Discover translation pairs

Find all files matching the *.{lang}.md pattern (e.g., readme.zh.md, contributing.fr.md). For each, identify the English source by stripping the language suffix (e.g., readme.zh.md pairs with readme.md).

If context shows CANONICAL_REPO and HAS_AWESOME_TEMPLATE, look inside repomatic/data/awesome_template/.github/ instead of the repo root.

Report the discovered pairs as a table:

If no translation files are found, tell the user and suggest creating one.

Step 2: Structural comparison

For each pair, compare the heading structure (all #, ##, ###, #### headings). Report:

1. Heading count match — same number of headings at each level.
2. Missing sections — headings present in English but absent from the translation.
3. Extra sections — headings in the translation with no English counterpart (may indicate stale removed sections).
4. Order alignment — whether sections appear in the same order.

Step 3: Content drift detection

For each section (delimited by headings), compare the English and translated versions:

1. Link inventory — extract all URLs from both. Flag URLs present in English but missing from the translation, or vice versa. URLs should be identical (not translated).
2. List item count — count bullet points and numbered items per section. A mismatch signals added or removed entries.
3. Code block count — code blocks should match 1:1.
4. Badge/image parity — compare ![ image references and shield.io badge URLs.
5. HTML block parity — compare <p>, <table>, and other HTML blocks that should be structurally identical.

Step 4: Staleness report

Present findings grouped by severity:

Structure breaks (sections added/removed in English but not reflected):

Content drift (section exists in both but content diverged):

Cosmetic (non-blocking but worth fixing):

Step 5: Draft translations for stale sections

For each section flagged as drifted or missing, draft an updated translation:

1. Show the current English section content.
2. Show the current translation (if it exists).
3. Draft the updated translation, preserving:
   • All URLs, code blocks, and HTML exactly as in the English source.
   • The translation style and terminology already established in the file (read the existing translation to learn the voice).
   • Markdown formatting and indentation.
4. Present the draft as a diff the user can review and apply.

Do not auto-apply changes. Present all drafts for user review first.

Step 6: Validate language badges

Check that both the English source and translation include matching language switcher badges. The expected pattern (from existing repos):

<p align="center">
  <a href="..." hreflang="en"><img src="https://img.shields.io/badge/lang-English-blue?style=flat-square" lang="en" alt="English"></a>
  <a href="..." hreflang="zh"><img src="https://img.shields.io/badge/lang-中文-blue?style=flat-square" lang="zh" alt="中文"></a>
</p>

Flag files missing the badge block or with mismatched language entries.

Guidelines

• URLs, code blocks, and HTML tags are never translated. They must be identical in source and translation.
• Section ordering in the translation must match the English source.
• When drafting translations, match the register and terminology of the existing translated content. Do not impose a different style.
• For awesome-falsehood, sections are in alphabetical order (per contributing.md). Verify the translation preserves this.
• The PR template checklist item "I applied the changes to all translatations in readme.*.md files" is the contributor-facing enforcement. This skill is the maintainer-facing verification.

Next steps

Suggest the user run:

• /awesome-triage to check if any open PRs need translation updates before merging.
• /repomatic-audit to verify broader upstream/downstream alignment.
