get_image_counts

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

With no annotations, the description bears full responsibility for behavioral disclosure. It does not indicate whether this is a read-only operation, whether it requires specific permissions, or what happens if an invalid env_id is provided. The minimal description fails to disclose traits beyond the basic function.

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, straightforward sentence with no unnecessary words. It is appropriately front-loaded, but its brevity sacrifices completeness.

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 lack of output schema and the low parameter coverage, the description should provide more context about return values (e.g., format of statistics) or expected input formats. It is insufficient for an agent to invoke this tool correctly without additional inference.

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%, and the description does not explain the purpose or constraints of the 'env_id' or 'agent_token' parameters. For example, it does not clarify what 'env_id' refers to or whether 'agent_token' is for authentication. The description fails to add any meaning beyond the schema's technical structure.

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 'Get image count statistics for the environment' clearly states the action (get) and the resource (image count statistics), specifying the context (for the environment). While distinct from siblings like 'list_images' which returns list info, the term 'statistics' is slightly vague—what exactly constitutes image count statistics? A more precise description could elevate clarity.

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?

No guidance is provided on when to use this tool versus alternatives such as 'get_container_counts' or 'get_volume_counts'. The description merely states what the tool does without mentioning prerequisites or recommended contexts.

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