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

No annotations are provided, so the description carries full burden. It implies a write operation ('Insert') but doesn't disclose behavioral traits like required permissions (Google email parameter suggests authentication), whether the operation is idempotent, error handling for invalid URLs, or what the output contains. The description is minimal and lacks critical operational context.

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, clear sentence with zero waste. It's front-loaded with the core action and resource, making it easy to parse quickly. Every word contributes directly to the purpose without redundancy.

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 the tool's complexity (8 parameters, mutation operation) and lack of annotations, the description is incomplete. It doesn't cover parameter meanings, behavioral details, or usage context. However, an output schema exists, so return values needn't be explained. The description provides a basic functional overview but misses critical operational guidance.

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 low (13%), with only 'image_url' having a description. The tool description adds no parameter semantics beyond implying 'image_url' must be public. It doesn't explain other parameters like 'user_google_email', 'presentation_id', 'page_object_id', or the positioning defaults ('left', 'top', 'width', 'height'), leaving most parameters undocumented.

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 ('Insert') and resource ('an image onto a slide'), specifying it comes 'from a public URL'. It distinguishes from siblings like 'insert_doc_image' by focusing on slides, but doesn't explicitly differentiate from other slide-related tools like 'create_slides_shape' or 'create_slides_text_box'.

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 guidance on when to use this tool versus alternatives is provided. It doesn't mention prerequisites (like needing a presentation ID), compare with similar tools (e.g., 'insert_doc_image' for documents vs. slides), or specify constraints (e.g., URL accessibility). The description is purely functional without contextual advice.

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