The Agent Skills Directory

[SAFE]: The skill documents standard iOS development practices for NFC integration, emphasizing correct entitlement usage (preferring TAG over legacy NDEF values) and mandatory privacy keys such as NFCReaderUsageDescription in Info.plist.
[INDIRECT_PROMPT_INJECTION]: The skill describes an architecture that ingests data from physical NFC tags, which are untrusted external sources. 1. Ingestion points: didDetectNDEFs and didDetect tags delegate methods in SKILL.md and references/nfc-patterns.md. 2. Boundary markers: None present in the code snippets for filtering tag content; however, the session availability is checked via readingAvailable. 3. Capability inventory: Reading and writing NDEF messages, parsing payload records, and sending APDU commands to tags. 4. Sanitization: The examples demonstrate how to extract text and URLs but do not provide explicit sanitization logic for the extracted values before application use.
[METADATA_POISONING]: The metadata fields including name, description, and contents are consistent with the provided code snippets and do not contain deceptive instructions.
