Behavior2/5

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

There are no annotations, so the description must carry the full burden. It only states the action 'List accepted weaknesses' without disclosing pagination behavior, required program_handle, or the shape of the response. The read-only nature is implied by 'List' but not explicitly stated.

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

Conciseness4/5

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

The description is a single concise sentence with no wasted words. However, its brevity comes at the cost of omitting crucial context, so it's efficient but under-specified.

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

Completeness2/5

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

The tool has no output schema and minimal description, leaving the agent without information about response format, pagination limits, or any filtering logic. Given the simple parameter set, a better description could easily provide this context.

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

Parameters2/5

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

The schema description coverage is only 33% (only program_handle has a trivial 'Program handle' description). The tool description does not explain page_size or page_number semantics, nor does it clarify that program_handle is the identifier for the program whose weaknesses are listed.

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

Purpose4/5

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

The description uses a specific verb 'List' and identifies the resource 'accepted weaknesses', which clearly distinguishes it from sibling tools like h1_get_program_scopes. However, it doesn't explicitly state that the list is scoped to a program, relying on the program_handle parameter for that context.

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

Usage Guidelines2/5

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

No guidance is provided on when to use this tool versus alternatives. There's no mention of prerequisites, related tools, or situations where h1_get_program_scopes or h1_get_program would be more appropriate.

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