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

Annotations indicate this is a non-read-only, non-destructive, non-idempotent operation, but the description adds no behavioral context beyond this. It does not explain what happens to existing branding on update, the effects of repeated calls, or expected side effects.

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 extremely brief at only four words. While not verbose, it is underspecified rather than efficiently concise—no sentences earn their place because none provide substantial guidance beyond the tool name.

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 configuration tool with 4 parameters performing write operations, the description is inadequate. It lacks information about return values, error conditions, the non-idempotent nature (per annotations), or interaction with existing branding configuration.

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?

With 100% schema description coverage, the parameters are fully documented in the schema itself (image formats, color enum values, type options). The description adds no parameter-specific guidance, meeting the baseline for high schema 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 'Configure or update exam branding' is essentially a tautology that restates the tool name (post_exam_branding). While it identifies the resource, it fails to distinguish from siblings like edubase_delete_exam_branding or edubase_get_exam_branding, or clarify scope.

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 provided on when to use this tool versus alternatives such as edubase_delete_exam_branding or edubase_get_exam_branding. No prerequisites (e.g., exam existence) or usage constraints are mentioned.

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