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.

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 concrete actions, includes natural trigger terms covering multiple ways users might phrase an RN upgrade request, explicitly states both what it does and when to use it, and occupies a clear niche that is unlikely to conflict with other skills.
| 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' (upgrades RN apps by applying diffs, updating dependencies, migrating native config, resolving build system changes, handling breaking APIs) and 'when' with an explicit 'Use when...' clause covering multiple trigger scenarios. | 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', 'React Native upgrade', plus technical terms like 'CocoaPods', 'Gradle', 'rn-diff-purge' that knowledgeable users would reference. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive niche focused specifically on React Native version upgrades with domain-specific terms like 'rn-diff-purge', 'CocoaPods', 'Gradle', and 'Expo SDK' that clearly distinguish it from general React, mobile development, or dependency update skills. | 3 / 3 |

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 serves as an effective hub for React Native upgrades. It provides a clear workflow sequence with executable commands, delegates detailed content to well-organized reference files, and includes both a quick reference table and a problem→skill mapping for easy navigation. The content is concise, actionable, and well-structured with no significant weaknesses.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and well-structured. It avoids explaining what React Native is or how upgrades work conceptually. Every section serves a clear purpose—routing, quick start commands, reference tables—with no padding or unnecessary explanation. | 3 / 3 |
Actionability | Provides concrete, executable commands for detecting the current version, fetching the template diff, reviewing changed files, installing dependencies, running CocoaPods, and validating builds on both platforms. The quick start block is copy-paste ready with clear comments. | 3 / 3 |
Workflow Clarity | The 6-step upgrade sequence is clearly numbered with explicit validation at step 6. The quick start code block includes a validation step (building both platforms) and a feedback mechanism (the curl error check). The sequence is logical and includes conditional steps (Expo). | 3 / 3 |
Progressive Disclosure | Excellent progressive disclosure: the SKILL.md serves as a concise overview and router, with all detailed content delegated to clearly labeled one-level-deep reference files. The quick reference table and problem→skill mapping table make navigation easy and intuitive. | 3 / 3 |
