The Agent Skills Directory

[INDIRECT_PROMPT_INJECTION]: The skill demonstrates patterns for handling external URLs via deep links and universal links. This introduces a surface for indirect prompt injection if untrusted data is processed without sufficient validation.
Ingestion points: onOpenURL and onContinueUserActivity modifiers located in SKILL.md and references/deeplinks.md.
Boundary markers: The provided patterns do not include explicit prompt boundary markers or 'ignore' instructions for the agent when processing link data.
Capability inventory: The skill enables programmatic navigation within the application state and opening system-level URLs.
Sanitization: The documentation advises validating URLs before navigation, although specific implementation for input sanitization is left to the user.
[EXTERNAL_DOWNLOADS]: The skill references external source code repositories and documentation sites.
Evidence: Link to a third-party Swift library https://github.com/Dimillian/AppRouter in references/navigationstack.md and a documentation link to https://sosumi.ai/documentation/xcode/supporting-universal-links-in-your-app in references/deeplinks.md.
