Full Analysis
- [EXTERNAL_DOWNLOADS]: Fetches the Bun installation script from
https://bun.sh/install. This reference is considered safe as it targets a well-known service and incorporates SHA-256 integrity verification to ensure the script has not been tampered with. - [DYNAMIC_EXECUTION]: The skill uses
evalto execute output fromgstack-slugand employs process substitution tosourceoutput fromgstack-repo-mode. These binaries are located within the user's local environment at~/.claude/skills/gstack/bin/. While these appear to be part of the skill's own tooling framework, dynamic execution of locally computed logic is a significant capability. - [INDIRECT_PROMPT_INJECTION]: The skill interacts with external, potentially untrusted web applications using a browser tool to generate reports. Malicious instructions embedded in a web page's HTML, metadata, or console logs could influence the agent's behavior during the testing process.
- Ingestion points: Browser tool outputs including page snapshots, link maps, and console error logs.
- Boundary markers: None present in the instructions to separate untrusted web content from the agent's instructions.
- Capability inventory: The skill possesses shell access (
Bash), file system write access (Write), and network access (WebSearch). - Sanitization: No specific sanitization or filtering of external data is described before the agent processes it for reporting.
- [COMMAND_EXECUTION]: Executes various Git commands (
git diff,git log,git commit) to analyze the project's state and automatically updateCLAUDE.mdwith skill routing rules based on user preferences.
Recommendations
- HIGH: Downloads and executes remote code from: https://bun.sh/install - DO NOT USE without thorough review
