Lists numerous specific concrete areas covered: packages, constructors, structs, interfaces, constants, enums, errors, booleans, receivers, getters/setters, functional options, acronyms, test functions, and subtest names. Also provides concrete naming examples like 'New vs NewTypeName', 'ErrNotFound vs NotFoundError'.

Clearly answers both 'what' (Go naming conventions covering a comprehensive list of areas) and 'when' (explicit 'Use this skill when...' clause with multiple trigger scenarios). Also includes a 'Do NOT use' boundary condition, which further strengthens completeness.

Excellent coverage of natural terms users would say: 'Go naming best practices', 'MixedCaps vs snake_case', 'ALL_CAPS constants', 'Get-prefix on getters', 'error string casing', 'utils/helpers anti-patterns', and specific naming alternatives like 'isConnected vs connected'. These are highly natural phrases a developer would use.

Highly distinctive — narrowly scoped to Go naming conventions specifically, not general Go programming. The explicit 'Do NOT use for general Go implementation questions that don't involve naming decisions' boundary further reduces conflict risk with other Go-related skills.

The skill is generally well-organized and avoids explaining basic Go concepts, but it's quite long with some redundancy — the 'Common Mistakes' table repeats information already covered in earlier sections (e.g., stuttering, ALL_CAPS, boolean fields, error strings). The Quick Reference table and the detailed sections overlap significantly.

The skill provides concrete, specific naming patterns with clear good/bad examples throughout. The Quick Reference table, code blocks, and Common Mistakes table all give copy-paste-ready patterns and exact naming conventions that Claude can directly apply when writing or reviewing Go code.

This is primarily a reference/convention skill rather than a multi-step workflow, so the single-task clarity standard applies. The content is clearly sequenced from quick reference → key rules → detailed categories → common mistakes → enforcement, which is logical and unambiguous for a naming conventions guide.

The skill references five detailed category files under './references/' and cross-references other skills, which is good structure. However, no bundle files were provided, so the referenced files don't actually exist in the bundle. Additionally, the SKILL.md itself is quite long — some of the detailed content (like the extensive Common Mistakes table) could have been pushed to the reference files to keep the overview leaner.
