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

With no annotations provided, the description carries full burden for behavioral disclosure. It states the action ('Pause a subscription') but doesn't explain what pausing entails—whether it's reversible, affects billing, requires specific permissions, or has side effects. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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 appropriately sized and front-loaded with the core purpose. The two-sentence structure is efficient, though the parameter explanations could be slightly more informative without sacrificing conciseness.

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 complexity (a mutation operation), lack of annotations, and 0% schema description coverage, the description is incomplete. It covers the basic action and parameters but misses critical context like behavioral effects, prerequisites, and differentiation from siblings. The presence of an output schema helps, but the description should do more to compensate for missing structured data.

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 0%, so the description must compensate. It lists both parameters with brief explanations ('The Conekta customer ID', 'The subscription ID to pause'), adding basic semantics beyond the schema's titles. However, it doesn't provide format details, validation rules, or examples, leaving gaps in parameter understanding.

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 verb ('Pause') and resource ('a subscription'), making the tool's purpose immediately understandable. However, it doesn't differentiate itself from sibling tools like 'cancel_subscription' or 'resume_subscription', which would require more specific language about what pausing entails versus those alternatives.

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 like 'cancel_subscription' or 'resume_subscription'. It doesn't mention prerequisites, consequences, or appropriate contexts for pausing a subscription, leaving the agent to infer usage from the tool name alone.

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