The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill references official and well-known packages including firebase, firebase-admin, and @firebase/rules-unit-testing from the npm registry.
[CREDENTIALS_UNSAFE]: The skill correctly demonstrates using environment variables (e.g., NEXT_PUBLIC_FIREBASE_API_KEY, FIREBASE_SERVICE_ACCOUNT_KEY) for sensitive configuration rather than hardcoding credentials.
[COMMAND_EXECUTION]: Code snippets include standard package installation commands and emulator startup commands which are expected for a developer-oriented skill.
[DATA_EXFILTRATION]: Network operations are confined to official Firebase authentication and database endpoints as part of the intended functionality.
[PROMPT_INJECTION]: No patterns attempting to override agent instructions or bypass safety filters were detected in the skill content or metadata.
