The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill provides instructions to register an MCP tool from https://mcp.manypi.com/mcp. This resource is hosted on a domain associated with the skill author (manypicom) and is used for the primary functionality of the skill.
[COMMAND_EXECUTION]: Includes utility scripts using common tools like grep, cut, sort, and dig. These are used for local syntax validation and DNS mail record lookups, which are standard practices for email verification.
[INDIRECT_PROMPT_INJECTION]: The skill processes user-provided email lists (emails.txt).
Ingestion points: Reads from emails.txt in multiple shell snippets within SKILL.md.
Boundary markers: None explicitly defined in the provided scripts.
Capability inventory: Uses dig for network lookups and curl for API communication.
Sanitization: The scripts use regular expressions for syntax filtering and implement variable quoting to prevent basic command injection during processing.
