TDQS

A4.1/5.0

Scored across 2 tools

Disambiguation5/5

The two tools have clearly distinct outputs: compile generates source code, while validate only checks syntax and semantics without generating code. The descriptions explicitly cross-reference each other ("without generating source code"), leaving no room for misselection.

Naming Consistency5/5

Both names follow a strict verb_noun pattern (compile_asn1_schema, validate_asn1_schema) sharing the same object noun, making the pairing predictable and readable.

Tool Count3/5

Two tools is thin for a codec/schema toolchain; a focused compiler wrapper can justify this, but the surface feels minimal and borderline for the apparent domain scope.

Completeness3/5

Compile and validate cover the schema authoring lifecycle, but there are notable gaps: no runtime encode/decode of data, no listing of supported languages/encodings, and no inspection of generated artifacts. Agents can work around these, but the surface is not complete for codec workflows.

Available Tools

2 tools
compile_asn1_schemaAInspect

Compiles ASN.1 schema definitions into executable source code. Use this tool whenever a user asks to generate code, compile an ASN.1 schema, or create a codec (e.g., DER, PER, UPER, BER) for a specific programming language. The tool returns the compilation status, error messages, and files containing the generated source code.

Inputs: codec, userId, fileName, schemaContent, +1 more.

validate_asn1_schemaAInspect

Validates ASN.1 schema definitions syntax and semantics. Use this tool whenever a user asks to validate, check, or verify an ASN.1 schema without generating source code. The tool returns a list of messages (informational, warnings, and errors).

Inputs: fileName, schemaContent.
