Full Analysis
- [EXTERNAL_DOWNLOADS]: The skill fetches an OpenAPI schema configuration from a remote GitHub repository hosted at
https://raw.githubusercontent.com/holon-run/uxc/main/skills/blockscout-openapi-skill/references/blockscout-v2.openapi.json. Additionally, the skill interacts with external Blockscout API endpoints, one of which (https://optimism.blockscout.com/api/v2) has been flagged by automated scanners. - [COMMAND_EXECUTION]: The skill instructs the agent to use the
uxcCLI tool to link and execute commands, such asuxc link blockscout-openapi-cliandblockscout-openapi-cli get:.... This involves shell execution for network-bound operations. - [INDIRECT_PROMPT_INJECTION]: The skill ingests untrusted data from external blockchain explorer APIs, creating a potential surface for indirect prompt injection if the data contains malicious instructions targeted at the agent.
- Ingestion points: The skill reads transaction history, token metadata, and address summaries via the Blockscout API as defined in
references/blockscout-v2.openapi.json. - Boundary markers: Instructions suggest parsing stable JSON fields (
ok,kind,data), but there are no explicit warnings to ignore instructions embedded within the retrieved data. - Capability inventory: The skill utilizes
uxcfor network requests and command execution. - Sanitization: No evidence of data sanitization or escaping of the external API responses before interpolation into the agent's context is provided.
