create_container

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

The description adds the key behavioral trait 'without starting it', which is not covered by annotations (readOnlyHint=false, destructiveHint=false). It does not mention permissions or side effects, but for a creation tool, this is reasonably transparent.

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 short and structured with 'args:' and 'returns:' sections, making it easy to scan. Every sentence adds value, though it could be more compact.

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 no output schema, the description mentions the return type (dict of attrs) but does not elaborate. The parameter descriptions are present but lack depth. Compared to sibling tools, it doesn't guide the agent on when to choose this over others like create_service or commit_container.

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 provides brief descriptions for each parameter ('image', 'command', 'extra_kwargs'), but the explanation for extra_kwargs is vague ('Additional keyword arguments forwarded to ContainerCollection.create'). Baseline would be higher for complete coverage, but here it adds some value.

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 'Create a container without starting it' uses a specific verb and resource, and the 'without starting' clause clearly distinguishes it from siblings like run_container that start the container.

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 explicit guidance on when to use this tool versus alternatives. The description only states what it does, leaving the agent to infer usage context from the sibling list.

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