createHeatmapPlaceholderSlide

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

No annotations are present, so the description bears full responsibility for behavioral disclosure. It states 'create or update' implying mutation, but does not disclose permissions required, side effects, or how the update mechanism works (the _index parameter in the schema provides some detail, but the description does not mention it).

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 sentence, which is concise but may be too terse. It front-loads the action but omits structural elements like parameter listing or behavioral notes.

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 four parameters and no output schema, the description is insufficient. It does not explain how rows and cols correspond to values, the format of a heatmap placeholder, or the consequences of the _index parameter for updates.

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 low (25%), with only the _index parameter having a description. The description does not explain rows, cols, or values beyond their types, leaving the agent to infer that these define the heatmap's dimensions and data cells.

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 a heatmap placeholder,' which clearly identifies the action and resource. It distinguishes from sibling tools like createBarChartSlide or createLineChartSlide by specifying 'heatmap placeholder,' but does not elaborate on what a heatmap placeholder entails.

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 alternatives such as createComplianceHeatmapSlide or other slide creators. The description lacks context for appropriate usage scenarios or exclusions.

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