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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the action ('Run') but lacks critical details: it doesn't specify permissions required, whether this is a one-time execution or managed service, potential side effects (e.g., resource consumption, costs), or error handling. For a tool that likely involves infrastructure changes, 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 in the first sentence and parameter details following in a structured list. There's no wasted text, but it could be slightly more concise by integrating the default value note into the 'replicas' explanation rather than a separate sentence.

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 (running ECS tasks), lack of annotations, and an output schema (which exists but isn't shown), the description is moderately complete. It covers the basic action and parameters but misses behavioral context like execution outcomes, error cases, or integration with sibling tools. The output schema likely handles return values, reducing the burden, but more operational guidance is needed.

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 adds meaning by explaining each parameter's role: 'tenant_id' specifies the context, 'family_name' identifies the task definition, and 'replicas' indicates the number of instances with a default. However, it doesn't provide format details (e.g., what a 'family_name' looks like), constraints (e.g., valid ranges for 'replicas'), or examples, leaving some ambiguity.

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 action ('Run an ECS task') and the resource ('from a task definition family'), making the purpose immediately understandable. It distinguishes from sibling tools like 'ecs_task_list' or 'ecs_task_def_list' by focusing on execution rather than listing. However, it doesn't explicitly differentiate from other ECS-related siblings like 'ecs_service_update' in terms of scope or resource type.

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 doesn't mention prerequisites (e.g., needing an existing task definition), compare it to sibling tools like 'ecs_service_update' for service-based tasks, or specify scenarios where running a task is appropriate over other operations. Usage is implied but not explicitly defined.

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