pull_image

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

Annotations indicate it is not read-only (readOnlyHint=false) and not destructive (destructiveHint=false). The description adds that pulling modifies the local image store but does not disclose network dependency, authentication requirements, or potential failure modes. It does not contradict annotations.

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 extremely concise with a single summary sentence and a clear, well-structured parameter list. No unnecessary words or fluff.

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 that an output schema exists (implied), the description covers parameter semantics and return type. It lacks information on error scenarios or prerequisites but is sufficient for basic usage and understanding of the tool's effect.

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 input schema has 0% parameter descriptions. The description adds meaning by explaining each parameter, including the dependency of 'tag' on 'all_tags' and the format for 'platform'. This is essential for correct usage, though it could be more specific about repository naming conventions.

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 'pull' and resource 'image', and distinguishes from sibling tools like load_image or build_image by indicating it pulls from a remote registry. The parameter breakdown adds clarity about the operation.

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 usage guidelines are provided. The description does not mention when to use this tool vs alternatives like search_images, compose_pull, or when prerequisites (e.g., authentication) are needed. There is no guidance on context or exclusions.

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