Image Inspect Tool

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

With no annotations, the description carries the full behavioral burden and discloses almost nothing: it implies a read-only lookup but never states it, and says nothing about permissions, error behavior when the name is unknown, or scope. An output schema exists so return format needs no explanation, but the safety/behavior profile is unaddressed.

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?

A single efficient sentence with no filler and the resource front-loaded. It is appropriately sized for a simple one-parameter tool, though it is so terse that it borders on under-specification rather than true concision.

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 output schema covers return values and the lone parameter is fully documented, so the core contract is intact. However, with no annotations anywhere in the definition, the description should compensate with at least read-only intent, and it does not.

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?

There is a single parameter and schema description coverage is 100% ('Image name, tag, or ID'), so the schema fully documents it. The description adds no syntax, format, or matching-rule detail beyond the schema, making the baseline of 3 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?

States a specific verb (get detailed information) and resource (image), so the agent knows it's a read operation returning image details. It doesn't explicitly differentiate from image_list_tool, but the inspect/list split is implied by naming convention shared across the sibling set.

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 when-to-use or when-not-to-use guidance is given, and no alternative is named (e.g., image_list_tool for enumerating images). The agent must infer from the name alone that this is the detailed single-image lookup rather than a listing.

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