slides_insert_image

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

No annotations are provided, so the description carries the full burden. It only states the basic action and does not disclose behavior such as whether the URL is fetched, how placement works, what happens on failure, or what is returned.

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 single sentence is clear, front-loaded, and contains no fluff, making it easy to parse. However, given the seven-parameter schema, it is arguably too terse to support effective parameterization.

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?

With no annotations, no parameter descriptions, and no mention of output behavior, the description is insufficient for an agent to use the tool confidently. It covers only the core action and leaves coordinate semantics, defaults, and return values unaddressed.

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% for 7 parameters, and the description does not explain the meaning of x_pt, y_pt, width_pt, or height_pt. The only parameter hint is 'from a URL' implicitly matching image_url, but positions and dimensions remain unexplained.

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 uses a specific verb ('Insert') and resource ('an image onto a slide') with a source ('from a URL'). It clearly distinguishes the tool from siblings such as docs_insert_image and slides_insert_video/shape/table.

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 implies a use case — adding an image to a slide — but provides no guidance on when to use this tool versus alternatives. Sibling tools like docs_insert_image and other slides_insert_* functions exist, yet no exclusions or alternative references are given.

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