Names the domain (README files in English and Japanese) and the core actions (confirm/execute synchronization, simultaneous updates), but doesn't list multiple granular actions beyond 'confirm and execute sync'.

Clearly answers both 'what' (synchronize README.md and README_ja.md bilingual versions) and 'when' (when README is changed, both language versions need simultaneous updates), with explicit trigger terms listed.

Includes natural trigger terms in both Japanese and English: 'README更新', 'README同期', 'readme sync', plus mentions specific filenames 'README.md' and 'README_ja.md'. These are terms users would naturally say when needing this skill.

Very specific niche: bilingual README synchronization between English and Japanese versions. Unlikely to conflict with other skills due to the narrow scope targeting specific files (README.md and README_ja.md).

The content is mostly efficient and project-specific, but the translation glossary table and some of the checklist items feel like they could be more compact. The skill doesn't over-explain concepts Claude knows, but the formatting adds some bulk.

The workflow steps are clear and the translation glossary provides concrete mappings, but there's no executable code—just pseudo-instructions like 'Read README.md'. The diff detection relies on Claude's judgment rather than concrete commands or scripts. The example diff report is helpful but the actual execution steps are vague.

The 4-step workflow is clearly sequenced: detect diffs → report → sync → final validation. Step 4 provides an explicit validation checklist, and the process includes a feedback loop where you verify after making changes. The sequence is logical and complete for this type of task.

For a skill under 50 lines of core content with no need for external references, the content is well-organized with clear sections (Overview, When to Use, Instructions with numbered steps, Guidelines). No bundle files are needed for this straightforward synchronization task.
