Names the domain (REST APIs, Fiber v2) and mentions some technologies (GORM/SQLX, Express-inspired routing), but 'scaffold and develop' is somewhat vague and doesn't list multiple concrete actions like 'create endpoints, handle middleware, configure database connections'.

Describes what the skill does but completely lacks a 'Use when...' clause or any explicit trigger guidance. Per rubric guidelines, missing explicit trigger guidance caps completeness at 2, and this has no 'when' component at all.

Includes relevant keywords like 'REST APIs', 'Fiber', 'GORM', 'SQLX', 'Go', but misses common user variations like 'web server', 'HTTP endpoints', 'API routes', 'golang', or 'backend service'.

Fiber v2 and GORM/SQLX provide some specificity, but 'REST APIs' and 'Go patterns' could overlap with other Go web framework skills or general API development skills.

The skill is lean and efficient, providing executable code without explaining basic concepts Claude already knows. Every section serves a purpose with no padding or unnecessary explanations about what Go, REST APIs, or web frameworks are.

Fully executable code throughout - scaffold commands are copy-paste ready, all Go code examples are complete and runnable, and common commands section provides exact CLI invocations. No pseudocode or vague instructions.

Clear sequenced workflow in 'First Steps After Scaffold' section with numbered steps. The project structure is explicit, and the scaffold command shows exact dependency installation order. Common commands section provides clear operational guidance.

Content is well-organized with clear sections, but this is a monolithic file with ~400 lines of code examples that could benefit from splitting into separate reference files (e.g., HANDLERS.md, DATABASE.md, MIDDLEWARE.md). The Integration Notes section at the end could be a separate file.
