validate.sscc

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. It includes 'Deterministic' which hints at no side effects, but fails to disclose return behavior on valid vs invalid input or any error conditions. The tool is likely safe but lacks full transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is only two sentences, front-loads the key action (validate), and includes essential detail without unnecessary words. Every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple one-parameter validation tool with no output schema, the description provides adequate context about the input and purpose. However, it lacks information about the return format (e.g., boolean, error messages) which would complete the picture for an agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema describes the parameter as '18-digit SSCC.' The description adds extra context: the GS1 mod-10 check digit, the full name, and the purpose in logistics. This enriches the parameter meaning beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool validates an SSCC, explains the acronym, specifies 18 digits with GS1 mod-10 check digit, and gives the use case (logistic units in shipping). This distinguishes it from sibling validators that handle different code types.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for SSCC validation but does not provide explicit when-to-use or when-not-to-use guidance compared to other validation siblings like validate.gtin or validate.gln. No alternatives are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
