Create or update a waterfall chart slide with numeric steps, each containing a label and value. Append a new slide or replace an existing one by specifying its index.
Create or update a numeric waterfall steps placeholder.
| Name | Required | Description | Default |
|---|---|---|---|
| steps | Yes | ||
| title | No | ||
| _index | No | If 0 <= _index < slides.length, update that position. Omit or -1/out-of-range to append to the end (default -1). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, description only says 'create or update' but does not disclose any behavioral traits such as side effects, prerequisites, or permission needs. No mention of what happens to existing slides or placeholder behavior.
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?
Extremely concise but at the cost of missing essential information. Under-specification is not beneficial.
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?
Complete lack of output schema and missing behavioral details. Given multiple sibling tools, a rich description is needed but not provided.
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 coverage is only 33% (only _index described). Description does not explain the meaning of 'steps' array or 'title' string, leaving agents to guess. Critical parameter 'steps' has no additional context.
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?
Description specifies action (create/update) and resource (numeric waterfall steps placeholder), clearly stating the tool's function. However, it does not differentiate from sibling tool createPricingWaterfallSlide, reducing precision.
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 like createPricingWaterfallSlide or other slide creators. Sibling list is large with no differentiation hints.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
