The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill installs the diffity package globally via npm install -g diffity if it is not found on the system path. This is a standard installation procedure for the tool this skill manages.
[COMMAND_EXECUTION]: The skill uses the system shell to execute which diffity for presence checking and diffity to start the background server process.
[PROMPT_INJECTION]: The skill is susceptible to indirect prompt injection because it ingests and processes data from the local working tree and staged changes. 1. Ingestion points: Source code and diffs from the current working directory. 2. Boundary markers: No explicit delimiters or instructions are used to distinguish codebase content from agent instructions. 3. Capability inventory: The skill can execute shell commands and modify the local file system (specifically checking for the .diffity directory). 4. Sanitization: No sanitization of the ingested code content is performed before it is processed by the diffity tool.
