Behavior2/5

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

With no annotations, the description must fully explain behavioral traits. It only states 'disable' without clarifying whether the action is reversible, requires special permissions, or what side effects occur (e.g., immediate effect, impact on ongoing notifications). The output schema exists but is not described.

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

Conciseness3/5

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

The description is a single sentence with no fluff, but it lacks necessary details. While conciseness is positive, the minimalism here results in under-specification. A slightly longer description would improve clarity without sacrificing brevity.

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?

Given the presence of an output schema and two simple parameters, the description fails to explain the outcome or behavior of disabling TxPUSH notifications. An agent would need additional context about effects, idempotency, or error conditions to use the tool correctly.

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

Parameters1/5

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

The input schema has two parameters with no descriptions (0% coverage). The description does not explain the meaning or role of 'customer_id' and 'account_id', leaving the agent to guess their significance. This is a critical gap for proper invocation.

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

Purpose5/5

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

The description clearly states the action ('Disable') and the resource ('TxPUSH notifications for an account'). It differentiates from the sibling 'subscribe_txpush' which performs the opposite action, so an agent can easily infer the tool's purpose.

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 (e.g., subscribe_txpush). There is no mention of prerequisites, such as whether an active subscription must exist, nor any usage context or exclusions.

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