Security Findings2

Severity	Finding	Layer	Location
HIGH	Unsafe Execution of Repository Scripts The skill explicitly instructs the agent to execute a bash script (`.specify/scripts/bash/check-prerequisites.sh`) located within the target repository. This constitutes an Arbitrary Code Execution risk. If the repository is untrusted, malicious, or compromised, the agent will execute potentially harmful code on the host system with the user's privileges. Replace the shell script execution with safe, read-only file inspection instructions (e.g., 'Read .specify/config.json'). Do not execute code found in the repository to determine configuration.	Unknown	SKILL.md:35
MEDIUM	Unvalidated Dynamic File Write The skill instructs the agent to write files to a directory (`FEATURE_DIR`) determined dynamically by the output of an external script. If the script returns a malicious path (e.g., absolute system paths or traversal sequences), the agent may overwrite sensitive files outside the repository scope. Explicitly instruct the agent to validate that `FEATURE_DIR` is a subdirectory of the current repository root before writing any files.	Unknown	SKILL.md:85
