The Agent Skills Directory

Command Execution: The skill instructs the agent to execute local commands and scripts to facilitate the migration process.
Evidence: The skill uses winapp new to generate projects and .\BuildAndRun.ps1 to validate the build. These are typical operations for a development-focused skill intended to automate environment setup and testing.
Indirect Prompt Injection Surface: The skill includes patterns for auditing local source code files, which creates a potential surface for indirect instructions.
Evidence Chain:
Ingestion points: The agent is instructed to read local C# files (*.cs) using PowerShell's Select-String to identify namespace usage.
Boundary markers: No specific delimiters are used when the agent processes the content of these source files.
Capability inventory: The skill utilizes PowerShell for file system navigation and string searching, along with the winapp CLI tool for project creation.
Sanitization: There is no explicit sanitization or filtering of the file content before it is processed by the search commands. While this is standard for audit tasks, it is a surface to be aware of when the agent interacts with external code.
