Full Analysis
- [EXTERNAL_DOWNLOADS]: The generated canvas artifact references external JavaScript and CSS libraries (
diff2htmlandhighlight.js) from thecdn.jsdelivr.netcontent delivery network, which is a well-known service. - [COMMAND_EXECUTION]: To support its visualization features, the skill uses platform-specific browser launchers (
open,xdg-open, orstart) to open generated HTML artifacts from the host's temporary directory. - [PROMPT_INJECTION]: The skill processes untrusted data from Pull Request URLs and diff ranges, creating a potential surface for indirect prompt injection.
- Ingestion points: PR metadata and code diffs provided via URL or range (SKILL.md).
- Boundary markers: The skill does not define specific delimiters or instructions for the agent to treat diff content as non-instructional data.
- Capability inventory: The skill possesses the ability to write files to the local temporary directory, execute browser-launching commands, and interact with the GitHub API (SKILL.md, references/CANVAS_MODE.md).
- Sanitization: There is no explicit description of sanitization or escaping logic for the PR data before it is embedded into the HTML canvas artifact.
- [REMOTE_CODE_EXECUTION]: In canvas mode, the skill performs dynamic code generation by populating an HTML/JavaScript template with PR data and executing it within a local browser environment.
