docker_list_images

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 only says 'List,' which implies a read operation, but doesn't explicitly confirm it's non-destructive, doesn't mention return format or pagination, and doesn't disclose any side effects.

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 two words: 'List Docker images.' It is extremely succinct, front-loaded, and contains zero wasted words, making it highly concise even though it under-specifies in other dimensions.

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?

The tool is simple, but the description lacks context such as what 'images' means (e.g., local, cached), prerequisites like Docker daemon, and doesn't mention the all_images behavior in prose. With many sibling tools, a bit more context would help differentiate it, but the schema and output schema mitigate some gaps.

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 coverage is 100% for the only parameter (all_images), with a description explaining intermediate layers. The tool description adds no parameter information, but the schema already does the heavy lifting, so the baseline of 3 is appropriate.

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 states 'List Docker images,' which is a specific verb and resource. It clearly distinguishes from container-related tools like docker_list_containers, though it doesn't go into detail about scope or variants.

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, no exclusions, and no context. It is a bare statement with no comparative or situational language.

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