The body is mostly efficient with valuable concrete examples, but it restates the description in the Overview/Tech Stack and includes generic guidance Claude already knows ('Keep tests focused and readable', 'Write tests first or alongside implementation', 'Ensure tests are deterministic') plus a filler 'Future Topics' section. It is not a 1 because it avoids explaining basic concepts like what RSpec is, but not a 3 because not every token earns its place.

Provides fully executable, copy-paste-ready code: the let!/let system-test example, the validation testing pattern with `build`, the complete TurboConfirmHelper module, and data-testid view/spec snippets, plus the `bundle exec rspec` command. It is not a 2 because the examples are concrete and complete rather than pseudocode or abstract direction.

Patterns are well-organized by topic and the test command is unambiguous, but there is no explicit multi-step sequence (e.g., write test → run rspec → read failure → fix → re-run) with validation checkpoints. It is not a 1 because the content is clearly structured, but not a 3 because no sequenced workflow with feedback loops is presented.

No bundle files exist (references/scripts/assets absent) and all content sits inline in one ~245-line file with well-organized headers; self-contained sections like the Turbo Confirm helper or the let!/let deep-dive could live in separate referenced files. It is not a 1 because it is well-organized rather than a monolithic wall, but not a 3 because there are no one-level-deep external references and nothing is split out.

Names concrete tools and platform — 'Write automated tests using RSpec, Capybara, and FactoryBot for Rails applications' — matching the anchor that lists specific concrete actions rather than vague language. It is not a 2 because it goes beyond naming a domain to specifying the exact frameworks and stack rather than generic 'writes tests'.

It explicitly answers both what ('Write automated tests using RSpec, Capybara, and FactoryBot for Rails applications') and when ('Use when implementing features, fixing bugs, or when the user mentions ...'). It is not a 2 because the 'Use when' trigger clause is explicit, not merely implied.

'Use when ... the user mentions testing, specs, RSpec, Capybara, or test data' gives good coverage of natural terms a user would say, plus 'implementing features, fixing bugs'. It is not a 2 because it includes common variations users actually utter, not just a single keyword.

The Rails + RSpec/Capybara/FactoryBot niche with distinct testing triggers is unlikely to fire for unrelated skills. It is not a 2 because the trigger terms are specific enough to avoid overlap with generic code or document skills.
