Full Analysis
- [EXTERNAL_DOWNLOADS]: The skill instructions in SKILL.md direct the agent to fetch the A2A protocol specification from a2a-protocol.org and search for integration examples on GitHub.
- [INDIRECT_PROMPT_INJECTION]: The skill is designed to ingest and process documentation from external sources, creating an attack surface for instructions embedded in that data.
- Ingestion points: External content is fetched from a2a-protocol.org and various framework-specific documentation sites (Google, LangChain, CrewAI, AWS, Microsoft) as defined in SKILL.md.
- Boundary markers: There are no explicit instructions or delimiters provided to ensure the agent ignores or isolates instructions that might be contained within the fetched documentation.
- Capability inventory: The skill has access to a broad set of tools, including Bash, Write, Edit, and WebFetch, which increases the potential impact of a successful injection.
- Sanitization: No sanitization, validation, or filtering of the external content is required before the agent processes it.
