list_countermeasures

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action ('List') but does not describe key traits such as whether this is a read-only operation, if it requires authentication, how pagination works (implied by 'page_size' but not explained), or what the output format looks like. This leaves significant gaps in understanding the tool's behavior.

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, efficient sentence with zero waste. It is appropriately sized and front-loaded, clearly stating the tool's purpose without unnecessary details, making it highly concise and well-structured.

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 complexity of a list operation with pagination and filtering, no annotations, and no output schema, the description is incomplete. It lacks details on behavioral traits, output format, and usage guidelines, failing to compensate for the missing structured data and leaving the agent with insufficient context for effective tool invocation.

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?

Schema description coverage is 100%, so the input schema fully documents the parameters (project_id, page_size, status). The description adds no additional meaning beyond what the schema provides, such as explaining parameter interactions or usage examples. Baseline score of 3 is appropriate as the schema handles the heavy lifting.

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 'List countermeasures for a project' clearly states the verb ('List') and resource ('countermeasures'), and specifies the scope ('for a project'). However, it does not differentiate from sibling tools like 'get_countermeasure' (singular) or explain what distinguishes listing from getting, leaving the purpose somewhat vague in context.

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 provides no guidance on when to use this tool versus alternatives. It does not mention when to use 'list_countermeasures' over 'get_countermeasure' (e.g., for multiple items vs. a single one), nor does it specify prerequisites or exclusions, offering only basic context without actionable usage advice.

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