The Agent Skills Directory

[COMMAND_EXECUTION]: The skill defines a local quality gate that involves executing standard Go development tools via the shell, such as gofmt, go mod, go test, go vet, golangci-lint, and nilaway. These commands are used to ensure code consistency and correctness within the local development environment.
[INDIRECT_PROMPT_INJECTION]: The skill facilitates the processing of external data in the form of Protocol Buffer definitions and descriptor sets which drive the code generation process.
Ingestion points: Untrusted data enters the context through .proto files and descriptor sets provided in the testdata/ directory and via the protogen plugin interface (documented in references/plugin-testing.md).
Boundary markers: The skill utilizes the standard protogen library which enforces the structured Protocol Buffer schema on all inputs, providing inherent structural boundaries.
Capability inventory: The system performs local compilation and test execution (go test) on the generated output to verify functional integrity as described in the quality gate.
Sanitization: The skill explicitly requires the use of strconv.Quote in references/plugin-conventions.md for any dynamic content or user-supplied strings (such as comments or option values) that are interpolated into the generated Go source code, mitigating potential code injection into the final output.
