Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a well-crafted skill description that follows best practices. It uses third person voice, specifies the exact technology (Rails 8), lists concrete capabilities, and includes an explicit 'Use when...' clause with natural trigger terms. The description is concise yet comprehensive.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'authentication using Rails 8 built-in generator', 'login/logout', 'session management', 'password reset flows', 'securing controllers'. These are concrete, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers both what ('Implements authentication using Rails 8 built-in generator') and when ('Use when setting up user authentication, login/logout, session management, password reset flows, or securing controllers') with explicit trigger guidance. | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'authentication', 'login/logout', 'session management', 'password reset', 'securing controllers'. These are terms developers naturally use when discussing auth features. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with 'Rails 8 built-in generator' specifying the exact framework and version. The combination of Rails-specific auth terminology creates a clear niche unlikely to conflict with generic auth or other framework skills. | 3 / 3 |

Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a solid, actionable skill with excellent code examples and good progressive structure. The main weaknesses are verbosity in showing generated code that Claude could infer, and missing validation steps after running the generator. The testing section is particularly strong with complete, executable specs.
Suggestions
Add validation checkpoint after 'bin/rails db:migrate' (e.g., 'Verify with: bin/rails routes | grep session' or check for expected files)
Condense the 'Generated Structure' and 'Core Components' sections - Claude can infer standard Rails patterns; focus on non-obvious customizations and gotchas
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is fairly comprehensive but includes some redundancy - showing full generated file structures and complete model implementations that Claude could infer. The 'Generated Structure' section and full model code listings add bulk that could be condensed. | 2 / 3 |
Actionability | Excellent executable code throughout - the Quick Start commands are copy-paste ready, all Ruby code examples are complete and runnable, and test examples include full context with setup and assertions. | 3 / 3 |
Workflow Clarity | The Quick Start provides a clear 2-step sequence, but lacks validation checkpoints. No guidance on verifying the generator ran correctly, checking migrations succeeded, or troubleshooting common issues after generation. | 2 / 3 |
Progressive Disclosure | Well-structured with clear sections progressing from Quick Start to Core Components to Usage Patterns to Testing. References to external files (sessions.md, current.md) are clearly signaled and one level deep. | 3 / 3 |
Total | 10 / 12 Passed |
Validation
90%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
