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

With no annotations provided, the description carries the full burden of behavioral disclosure. It implies a mutation operation ('Apply text formatting') but does not specify permissions required, whether changes are reversible, rate limits, or error handling. This leaves significant gaps in understanding the tool's behavior and constraints.

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 action and target, with no wasted words. It directly communicates the tool's purpose without unnecessary elaboration, making it easy to parse quickly.

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 with 12 parameters, no annotations, and an output schema (which reduces need to describe returns), the description is inadequate. It fails to address behavioral aspects like mutation effects, error conditions, or usage context, leaving the agent with insufficient information to invoke the tool safely and effectively.

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 formatting 'text inside a slide element', which aligns with parameters like 'bold', 'italic', and 'text_color', but does not add meaning beyond the schema. With schema description coverage at 50%, the description partially compensates by hinting at the tool's scope, but it does not clarify undocumented parameters such as 'start_index' or 'end_index' for text selection.

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 verb ('Apply text formatting') and resource ('text inside a slide element'), specifying the target as text boxes, shapes, or placeholders. However, it does not distinguish this tool from sibling tools like 'format_all_slides_text' or 'format_slides_paragraph', which handle similar formatting but at different scopes or elements.

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, such as 'format_all_slides_text' for bulk formatting or 'format_slides_paragraph' for paragraph-level styling. It lacks context on prerequisites, like needing to identify slide elements first, or exclusions, such as not applying to images or tables.

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