szlcsc_compare_parts

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It adds one behavioral trait: 'will not automatically declare direct replaceability.' This is useful context, but the description does not disclose other aspects like safety (read-only vs. destructive), performance, or error conditions. The behavioral transparency is minimal but not misleading.

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 a single sentence (two clauses) that front-loads the core action ('compare multiple specific parts side by side') and adds a key behavioral note. Every word earns its place; there is no redundancy or filler. It is appropriately brief for a simple tool.

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?

Given the tool's simplicity (one parameter, output schema present), the description covers the essential aspects: what it compares and what it returns. The output schema presumably documents the return structure, so the description does not need to repeat that. However, it could be more complete by specifying the expected format of identifiers, which is a minor gap.

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 input schema has 0% description coverage for the 'identifiers' parameter. The description refers to 'multiple specific parts' but does not explain the expected format of identifiers (e.g., part numbers, full IDs, or how many are allowed). The meaning is partially inferred but not explicitly clarified, which is insufficient for a tool with zero schema documentation.

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's purpose: comparing multiple specific parts side by side and returning differences in basic fields and same-name parameters. It distinguishes from sibling tools like szlcsc_find_alternatives (which finds replacements) and szlcsc_search (which searches broadly). The verb 'compare' and resource 'parts' are specific and unambiguous.

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 when to use the tool (i.e., when you want to compare specific parts) but does not explicitly state when not to use it or mention alternatives. While the purpose is clear, there is no guidance on choosing between this and similar tools like szlcsc_find_alternatives. The usage context is only hinted by the description itself.

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