Full Analysis
- [EXTERNAL_DOWNLOADS]: The skill downloads OpenAPI specifications from Clerk's official GitHub repository to dynamically discover API endpoints and schemas.
- Evidence:
curl -s https://raw.githubusercontent.com/clerk/openapi-specs/main/bapi/${version_name}inSKILL.md. - Context: The downloaded content is piped into local parsing scripts (
extract-tags.js,extract-tag-endpoints.sh) as data. - [COMMAND_EXECUTION]: A local helper script,
scripts/execute-request.sh, is designed to search for and source environment files to load API credentials. - Evidence:
source "$_envfile"used on.envand.env.localfiles discovered in the directory hierarchy. - Note: The skill instructions explicitly direct the agent not to use this specific script, reserving it for local developer use.
- [INDIRECT_PROMPT_INJECTION]: The skill accepts user input to define API paths and parameters, which creates a potential surface for indirect prompt injection.
- Ingestion points: User-provided strings via the
$ARGUMENTSvariable inSKILL.md. - Boundary markers: No explicit delimiters or boundary markers are used when interpolating these arguments into command templates.
- Capability inventory: The skill has access to shell execution (
Bash) and network operations (WebFetch/curl). - Sanitization: There is no evidence of input validation or sanitization for the parameters provided by the user before they are included in API request bodies or shell commands.
Recommendations
- HIGH: Downloads and executes remote code from: https://raw.githubusercontent.com/clerk/openapi-specs/main/bapi/${version_name} - DO NOT USE without thorough review
