Full Analysis
- [EXTERNAL_DOWNLOADS]: The skill uses
npx --yes great-cto@3.62.0to download and execute an external package from the npm registry. While version pinning is used to mitigate supply chain risks, it introduces a dependency on third-party code. - [COMMAND_EXECUTION]: The skill executes multiple subcommands via
Bash, includingdoctor,list,start, andapprove. These commands have the capability to interact with the project filesystem, Docker, and the GitHub CLI. - [INDIRECT_PROMPT_INJECTION]: The
startcommand template includes a--promptargument that interpolates user-provided text directly into the shell command. - Ingestion points: The
--promptflag in thecodex-host startcommand withinSKILL.md. - Boundary markers: The command template uses double quotes (
"the requested outcome") to wrap the user input, but the instructions do not specify a requirement for the agent to sanitize or escape shell-sensitive characters such as backticks, semicolons, or subshell syntax. - Capability inventory: The skill is configured with
ReadandBashtools. It specifies write boundaries via the--allowflag and can perform actions through external adapters like GitHub or local project directories. - Sanitization: No explicit input validation, sanitization, or filtering logic for the user-supplied prompt is described in the skill instructions.
