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 strong skill description that clearly defines a specific niche (AngularJS to Angular migration), lists concrete techniques, and includes an explicit 'Use when' clause with natural trigger terms. It follows third-person voice and is concise without being vague. The description would effectively differentiate this skill from other coding or framework-related skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'hybrid mode', 'incremental component rewriting', and 'dependency injection updates'. These are concrete migration techniques, not vague language. | 3 / 3 |
Completeness | Clearly answers both 'what' (migrate from AngularJS to Angular using hybrid mode, incremental component rewriting, and dependency injection updates) and 'when' (explicit 'Use when' clause covering upgrading AngularJS applications, planning framework migrations, or modernizing legacy Angular code). | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'AngularJS', 'Angular', 'migrate', 'upgrading', 'framework migrations', 'modernizing', 'legacy Angular code'. These cover common variations of how users would describe this need. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with a clear niche: AngularJS-to-Angular migration is a very specific domain. The triggers ('AngularJS', 'hybrid mode', 'legacy Angular') are unlikely to conflict with other skills. | 3 / 3 |

Implementation
22%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill reads more like a tutorial or reference document than an efficient skill file for Claude. It contains extensive code examples for patterns Claude already knows (AngularJS to Angular migration is well-documented knowledge), lacks any validation workflow for a complex multi-step process, and is far too verbose for its purpose. The referenced bundle files don't exist, undermining the progressive disclosure structure.
Suggestions
Drastically reduce inline code examples — Claude knows Angular and AngularJS syntax. Focus only on non-obvious patterns like the hybrid bootstrap setup and DI bridging, which are genuinely tricky.
Add an explicit step-by-step migration workflow with validation checkpoints (e.g., 'verify hybrid app boots correctly before migrating any components', 'run ng build after each component migration').
Remove generic advice sections (Best Practices, Common Pitfalls, Migration Timeline) that don't add value beyond what Claude already knows, or condense them to 2-3 truly non-obvious items.
Either provide the referenced bundle files or remove the Resources section — broken references add confusion without value.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is extremely verbose with extensive before/after code examples that Claude could generate on its own. It explains basic concepts like what migration strategies are, includes a timeline section with generic project management advice, and lists obvious best practices ('Test Continuously', 'Document'). Much of this is knowledge Claude already possesses. | 1 / 3 |
Actionability | The code examples are mostly concrete and executable (hybrid bootstrap, component conversion, service migration), which is good. However, many examples are incomplete (missing imports, partial class definitions), and the guidance is more of a reference catalog than actionable step-by-step instructions for performing a specific migration task. | 2 / 3 |
Workflow Clarity | Despite being a multi-step migration process with destructive/irreversible changes, there are no validation checkpoints, no feedback loops, and no verification steps. The 'Migration Timeline' is a vague project plan, not an executable workflow. There's no guidance on how to verify each phase succeeded before proceeding. | 1 / 3 |
Progressive Disclosure | The Resources section references several supporting files (references/hybrid-mode.md, scripts/analyze-angular-app.sh, etc.), which suggests good intent for progressive disclosure. However, no bundle files are provided, so these references are broken. The main file itself is monolithic with ~300 lines of inline code examples that could be split into referenced files. | 2 / 3 |
