createRevenueModelSlide

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

With no annotations, the description must disclose behavioral traits. It only mentions 'create or update' without explaining side effects (e.g., whether updating overwrites existing data, or if permissions are needed). The _index parameter hint in schema is not reflected in description.

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 very short (one sentence). While concise, it omits crucial context (e.g., that it creates a slide), making it under-specified. Every sentence should earn its place, but this one leaves too much unsaid.

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 creates/updates a slide with revenue model content, the description is incomplete. It does not explain how the slide fits into the presentation, the role of the _index parameter in positioning, or the return value. The schema partially describes parameters but lacks narrative context.

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 only 33%, and the description adds no parameter-level information beyond listing 'streams' and 'pricing notes.' It does not specify format, constraints, or relationships between parameters, failing to compensate for the schema's low coverage.

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 'Create or update revenue streams and pricing notes,' which identifies the action and subject. However, it does not explicitly mention that the tool creates or updates a slide, relying on the tool name for that context. Given sibling tools are all slide creators, the purpose is clear but could be more explicit.

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 on when to use this tool versus other slide creation tools (e.g., createPricingWaterfallSlide). The description lacks any context about scenarios or alternatives, leaving the agent to infer from the name alone.

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