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

With no annotations, the description carries the full burden of behavioral disclosure. It mentions the test action and return of identity, but fails to explain behavior when the container is unreachable, whether any side effects occur, or the exact return format. This is a significant gap for a network-tool operation.

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, front-loaded sentence with no filler. It effectively communicates the tool's core purpose in minimal words.

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 relatively simple with one parameter, but the absence of an output schema and lack of detail on failure behavior or identity format leave the description somewhat incomplete. It is adequate as a minimal health-check tool but does not fully equip an agent to handle edge cases.

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?

The schema already provides 100% coverage for the single parameter, describing 'container' as 'Docker container name or id.' The description adds no additional parameter-specific meaning, 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 clearly states the verb ('Test'), resource ('Docker container'), and the result ('reachable and return its identity'). It distinguishes this tool from sibling operations like docker_exec or docker_read_file by framing it as a connectivity check, though it does not explicitly name 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 phrase 'Test that a Docker container is reachable' implies the usage scenario (checking connectivity), but it does not explicitly state when to use this tool versus alternatives such as docker_exec or docker_interactive_exec. No exclusions or alternative trade-offs are mentioned.

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