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, plus an 'Also trigger when...' clause and a 'Do NOT use for...' exclusion boundary).

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, with explicit exclusion of general Go implementation questions. The specific naming examples and anti-patterns make it very unlikely to conflict with a general Go coding skill or other language naming skills.

The skill is generally well-organized and avoids explaining basic Go concepts, but it's quite lengthy with some redundancy — the 'Common Mistakes' table repeats information already covered in earlier sections (e.g., stuttering, MixedCaps, boolean fields, error strings). The 'Frequently Missed Conventions' section also overlaps with the quick reference table. Could be tightened by ~30%.

The skill provides concrete, specific naming patterns with clear good/bad code examples throughout. The quick reference table, inline code examples, and common mistakes table all give copy-paste-ready patterns 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 exemption applies. The content is clearly sequenced from quick reference → core rules → detailed categories → common mistakes → enforcement, which is logical and unambiguous for a naming conventions guide.

Excellent progressive disclosure — the SKILL.md provides a comprehensive quick reference and key rules inline, then clearly signals one-level-deep references to detailed category files (packages-files.md, identifiers.md, functions-methods.md, types-errors.md, testing.md) with descriptive summaries of what each contains. Cross-references to related skills are also well-signaled.
