HIGHLong base64-encoded blob hidden in the skill documentationSS-SKILL-INJECT-B64-PAYLOAD-01 · Prompt injection · README.md×2
HIGH — once decoded by the agent, an encoded payload has the same impact class as plain-text injection.
Why it matters
A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.

How to fix
Remove the encoded blob, or decode it and review what it actually contains.
- Decode the base64 string and confirm it is not an instruction directed at the agent.
- Move any legitimate binary or signature data into a dedicated file (
*.sig,SIGNATURES) outside the documentation.

Install
Recommended: any agent via skills CLI
The skills CLI is the recommended install method.
Interactive install (recommended):
npx skills add dpearson2699/swift-ios-skillsRunning the default command opens the skills CLI UI so you can choose which skills to install and which agent(s) to install them for.
Install everything for any coding agent:
npx skills add dpearson2699/swift-ios-skills --allUse --all when you want the full set of 84 skills installed automatically for any coding agent.
Install specific skills directly:
npx skills add dpearson2699/swift-ios-skills --skill <skill-name> --skill <skill-name>Check for updates to installed skills:
npx skills checkUpdate installed skills to the latest versions:
npx skills updateUse these after installing through the skills CLI.
Claude Code (via plugin marketplace)
Add the marketplace (one-time):
/plugin marketplace add dpearson2699/swift-ios-skillsInstall everything:
/plugin install all-ios-skills@swift-ios-skillsOr install a themed bundle (bundles limit how many skills load into the context window — if you want everything, use all-ios-skills above instead of installing multiple bundles):
/plugin install swiftui-skills@swift-ios-skills
/plugin install swift-core-skills@swift-ios-skills
/plugin install ios-app-framework-skills@swift-ios-skills

Compatibility
These skills work with any agent that supports the Agent Skills standard, including:
Upgrading from v2.x
v3.0 is a major release. If you previously installed v2.x skills, note the following changes:
- Skill count: 57 skills in v2.2.0, 76 skills in v3.0.0.
- Skill renames: 12 existing skills renamed to use Apple Kit framework names. Old skill paths no longer resolve. Uninstall all skills and reinstall to upgrade.
