sap_get_tool_category_summary

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

No annotations are provided, so the description carries full burden of behavioral disclosure. The description is too brief; it does not mention whether this is a read-only operation, any side effects, required permissions, or output format. With zero annotations, this information is missing.

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?

Single sentence, front-loaded with the verb and resource. No extraneous information. For a parameterless tool, this is appropriately concise, though it could be slightly more descriptive without being verbose.

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 no parameters, no output schema, and no annotations, the description is minimal. It states what it does but does not describe the return value or any contextual details like 'returns a list of categories with metrics'. Adequate for a simple fetch but incomplete for an agent to fully understand how to use the result.

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?

Input schema has no parameters (empty object), so schema coverage is 100%. With 0 parameters, baseline is 4. The description adds no parameter semantics because there are none to add. It correctly reflects that no inputs are needed.

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 action ('Fetch') and the resource ('SDK discovery summary across SAP tool categories'). It distinguishes itself from sibling tools by specifying it's a summary across categories, but does not explicitly differentiate from similar fetch/summary tools like sap_fetch_tool_category_index.

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?

No guidance on when to use this tool versus alternatives. Among many 'sap_fetch_' siblings, there is no indication of why one would choose this summary over other fetch tools. Lacks any when-to-use or when-not-to-use context.

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