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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Style' implies a mutation operation, but the description doesn't specify whether this requires edit permissions, if changes are reversible, potential side effects (e.g., overriding existing styles), or rate limits. It lacks critical context for a mutation tool with zero annotation coverage.

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, efficient sentence that front-loads the core purpose without unnecessary words. Every word earns its place, making it easy to parse quickly. There's no redundancy or fluff, which is ideal for conciseness.

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 the presence of an output schema (which reduces the need to describe return values), the description is minimally adequate. However, with no annotations and incomplete parameter coverage in the schema, it should provide more behavioral context (e.g., permissions, side effects) to be fully helpful for an agent.

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 description mentions 'fill and outline', which aligns with parameters like fill_color, outline_color, and outline_weight. With 63% schema description coverage (5 of 8 parameters have descriptions in the schema), the baseline is 3. The description adds minimal value beyond the schema, as it doesn't explain parameter interactions (e.g., fill_alpha with fill_color) or provide examples beyond what's in the schema descriptions.

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 'Style a shape's fill and outline' clearly states the verb ('Style') and resource ('shape'), specifying the target attributes (fill and outline). It distinguishes from siblings like 'format_slides_text' or 'set_slides_background' by focusing on shape styling rather than text formatting or background changes. However, it doesn't explicitly differentiate from 'create_slides_shape' or 'delete_slides_element', which are related but distinct operations.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing shape), exclusions (e.g., not for text boxes), or related tools like 'format_slides_paragraph' for text styling. Without such context, an agent must infer usage from the tool name and parameters alone.

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