upgrading-react-native
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.

2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.90). The skill explicitly instructs the agent to fetch and ingest public, user-editable Upgrade Helper/rn-diff-purge content (e.g., curl to https://raw.githubusercontent.com/react-native-community/rn-diff-purge/... and reading the RELEASES and Upgrade Helper URLs) and to build execution plans and apply diffs based on that fetched content, which could allow indirect prompt-injection via third-party pages/diffs.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.90). The skill explicitly downloads rn-diff-purge raw data at runtime (e.g. https://raw.githubusercontent.com/react-native-community/rn-diff-purge/diffs/diffs/<current_version>..<target_version>.diff and https://raw.githubusercontent.com/react-native-community/rn-diff-purge/master/RELEASES), which the workflow requires and whose fetched diff content directly drives the agent's upgrade instructions and edits.
