Full Analysis
- [EXTERNAL_DOWNLOADS]: The skill fetches a commit hash from the GitHub API and downloads a source archive from the renoise-ai GitHub organization (
https://codeload.github.com/renoise-ai/renoise-skills/tar.gz/<commit>). These downloads are used to update and install the skill's components to a local cache directory. - [COMMAND_EXECUTION]: The skill uses shell commands to manage its environment, specifically using
curlto download assets,mkdirfor directory management, andtarto extract downloaded content. It also utilizes the Renoisesandboxtool for execution. - [INDIRECT_PROMPT_INJECTION]:
- Ingestion points: The skill is designed to read and execute instructions from a secondary
SKILL.mdfile that is downloaded from a remote repository at runtime. - Boundary markers: No explicit in-prompt delimiters or boundary markers are defined in this bootstrap file for the content of the downloaded file.
- Capability inventory: The skill environment permits shell command execution, file system access (within
~/.cache/), and network access viacurl. - Sanitization: The skill relies on the vendor's CI process and the use of a
stablebranch for content verification, but it lacks runtime sanitization of the downloaded markdown instructions. It mitigates risk by requiring explicit user consent for cost-sensitive or task-creation operations.
