The Agent Skills Directory

[SAFE]: The skill provides standard documentation and best practice patterns for the Pydantic data validation library.
[SAFE]: Secret management is handled correctly by recommending the use of environment variables and .env files via pydantic-settings rather than hardcoding credentials. The documentation includes appropriate warnings for managing sensitive data like API keys and passwords.
[SAFE]: The skill includes explicit patterns for sanitizing user input and masking personally identifiable information (PII) during serialization using field_serializer and exclude options in Field definitions.
[INDIRECT_PROMPT_INJECTION]: The skill documents methods for ingesting untrusted data from external sources like API endpoints (e.g., in SKILL.md Competency 6 and EXAMPLES.md Example 12). While this represents a technical attack surface where an agent might process malicious data, the skill's primary focus is on providing the validation, sanitization, and strict schema enforcement necessary to mitigate such risks.
