Risk Level: SAFEINDIRECT_PROMPT_INJECTIONEXTERNAL_DOWNLOADS
Full Analysis
- [INDIRECT_PROMPT_INJECTION]: The skill interacts with external data from third-party providers (e.g., GitHub, Slack) which could contain malicious content. The skill instructions proactively mitigate this risk by requiring the agent to treat external content as data, not instructions.
- Ingestion points: Data retrieved from external providers through the
execute_composio_toolfunction. - Boundary markers: Explicit instructions in
references/security.mdstate that provider descriptions and records are untrusted data and must not influence action selection or authorization. - Capability inventory: The skill has the ability to execute writes to external services via
execute_composio_tooland perform destructive actions like toolkit disconnection. - Sanitization: Instructions mandate the redaction of sensitive credentials and the truncation of large payloads to prevent data exposure.
- [EXTERNAL_DOWNLOADS]: The skill references an external Model Context Protocol (MCP) server for its core functionality.
