The Agent Skills Directory

[INDIRECT_PROMPT_INJECTION]: The skill processes external requirement documents and mock payloads to generate API designs and Protobuf files, creating a potential surface for indirect instructions to influence the agent's output.
Ingestion points: Task intake logic in SKILL.md defines support for "Requirement + mock demo" and "Folder input" where untrusted external data enters the agent's context.
Boundary markers: The instructions do not define explicit boundary markers or instructions to ignore embedded prompts within the ingested requirement documents.
Capability inventory: The skill is equipped to use the TodoWrite tool for task management and has the capability to write files to the local file system (e.g., prd/API.md and design/ subdirectories).
Sanitization: There are no documented procedures for sanitizing or escaping the content derived from external requirement documents before it is used to generate the final API contracts.
[EXTERNAL_DOWNLOADS]: Reference documentation includes instructions for the installation of software dependencies from the vendor's official GitHub repository.
Evidence: references/go-sphere-error-handling-reference.md documents the installation of the protoc-gen-sphere-errors plugin using the command go install github.com/go-sphere/protoc-gen-sphere-errors@latest.
