The content is lean and efficient. It doesn't explain what Go modules are, what replace directives do conceptually, or how multi-module repos work — it assumes Claude knows all of this. Every section serves a clear purpose with no padding.

Provides the exact command to run (`dda inv create-module --path=<module-path>`), specifies what to collect from the user, includes a concrete table of `modules.yml` fields with values, and gives clear usage examples. The guidance is specific and directly executable.

The 5-step workflow is clearly sequenced with logical checkpoints: gather info → verify clean git state → run command → review output → report results. Step 2 serves as a validation gate before the destructive operation, and Step 5 includes error handling guidance. The task itself runs linters as built-in validation.

For a skill of this size and scope (single task, under 80 lines), the content is well-organized with clear sections, a reference table for configuration options, and no need for external files. The structure is appropriate and easy to navigate.

Names the domain (Go module) and a single action (create), but does not list multiple concrete actions or elaborate on what creating a Go module entails (e.g., initializing go.mod, setting up directory structure, adding dependencies).

Describes what it does (create a Go module) but provides no explicit 'Use when...' clause or trigger guidance for when Claude should select this skill. Per rubric guidelines, missing 'Use when' caps completeness at 2, and the 'what' is also quite thin, warranting a 1.

Includes relevant terms like 'Go module' and 'agent repository', but misses common variations users might say such as 'go.mod', 'Go package', 'new module', 'initialize module', or 'golang'.

Somewhat specific to Go modules in an agent repository, which narrows the scope, but could overlap with general Go development skills or repository scaffolding skills without clearer differentiation.
