Upgrades React Native apps to newer versions by applying rn-diff-purge template diffs, updating package.json dependencies, migrating native iOS and Android configuration, resolving CocoaPods and Gradle changes, and handling breaking API updates. Use when upgrading React Native, bumping RN version, updating from RN 0.x to 0.y, or migrating Expo SDK alongside a React Native upgrade.

Validation for skill structure
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 an excellent skill description that hits all the marks. It provides specific technical actions, includes natural trigger terms that developers would use, has an explicit 'Use when...' clause with multiple scenarios, and is highly distinctive to React Native version upgrades specifically.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'applying rn-diff-purge template diffs', 'updating package.json dependencies', 'migrating native iOS and Android configuration', 'resolving CocoaPods and Gradle changes', and 'handling breaking API updates'. | 3 / 3 |
Completeness | Clearly answers both what (upgrading RN apps with specific technical steps) AND when with explicit 'Use when...' clause covering multiple trigger scenarios including version bumping and Expo SDK migration. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'upgrading React Native', 'bumping RN version', 'updating from RN 0.x to 0.y', 'migrating Expo SDK', plus technical terms like 'CocoaPods', 'Gradle', and 'rn-diff-purge' that developers would naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with clear niche targeting React Native version upgrades specifically. The combination of RN-specific tools (rn-diff-purge), platform-specific concerns (CocoaPods, Gradle), and version migration language makes it unlikely to conflict with general React or mobile development skills. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-crafted skill that exemplifies good practices: it's concise, provides executable commands, has clear workflow sequencing with validation checkpoints, and uses progressive disclosure effectively through reference tables. The content assumes Claude's competence while providing the specific, actionable guidance needed for React Native upgrades.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient, avoiding explanations of what React Native is or how upgrades work conceptually. Every section serves a clear purpose with no padding or unnecessary context. | 3 / 3 |
Actionability | Provides fully executable bash commands for the upgrade workflow including curl for fetching diffs, npm/pod install commands, and build verification commands. The example is copy-paste ready with concrete version numbers. | 3 / 3 |
Workflow Clarity | Clear 6-step sequence with explicit validation at step 6. The bash example includes verification builds for both platforms as explicit checkpoints. The workflow has clear ordering and the validation step ensures both platforms build successfully before proceeding. | 3 / 3 |
Progressive Disclosure | Excellent structure with a concise overview, quick start commands, and well-organized one-level-deep references. The Quick Reference table and Problem → Skill Mapping provide clear navigation to detailed materials without nesting. | 3 / 3 |
