get_cwe_category

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

With no annotations, the description carries the transparency burden. It discloses that IDs are accepted with or without the 'CWE-' prefix and that 'all' is a special value, and it notes the return shape ('Dictionary with Categories array or error information'). While it doesn't explicitly state read-only behavior, the verb 'get' implies it, and the error handling disclosure provides useful context.

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 compact, with a single-sentence purpose followed by concise Args and Returns sections. Every line adds useful information, and the format is scannable.

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 getter with one parameter and an existing output schema, the description covers the core behavior and parameter semantics. It does not mention potential performance implications of 'all' or explicitly differentiate from sibling tools, but these are minor gaps.

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 defines only a bare string parameter, but the description thoroughly explains its semantics: comma-separated IDs, optional 'CWE-' prefix, and the special value 'all', with concrete examples. This far exceeds the schema's minimal information.

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 opens with 'Get CWE categories by ID(s) or all categories', clearly stating the action (get) and resource (CWE categories). This distinguishes it from sibling tools that target weaknesses, views, parents, or children.

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 when category data is needed, and the 'all' value suggests bulk retrieval. However, it does not explicitly mention when to use this tool over siblings like get_cwe_weakness or get_cwe_view, nor does it provide any exclusion criteria.

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