populate_placeholder

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

With no meaningful annotations beyond a title, the description carries the full burden for behavioral disclosure. It does not explain whether existing placeholder text is overwritten, what happens with invalid indices, whether a presentation must be open, or what errors may occur. The word 'populate' implies mutation but adds no operational detail.

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 concise sentence with no redundant words. It front-loads the core action, though it sacrifices necessary detail.

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?

For a tool with 4 parameters, 3 required, and 0% schema descriptions, the description omits critical semantics for slide_index, placeholder_idx, and presentation_id. It provides no usage context or behavior details, leaving the agent unable to reliably construct a valid call despite the presence of an output schema.

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%, and the description only names 'text' without adding semantics for slide_index, placeholder_idx, or presentation_id. The agent cannot infer indexing conventions, optionality, or default behavior from the description, so it fails to compensate for the schema's silence.

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 states a clear verb and resource: populate a placeholder with text. It identifies the core action without ambiguity, and 'placeholder' distinguishes it from generic text tools like manage_text, though it doesn't explicitly differentiate among siblings.

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 is provided about when to use this tool versus alternatives such as manage_text or add_bullet_points. There are no prerequisites, exclusions, or contextual hints beyond the generic description.

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