update_category

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

No annotations provided, so description must bear full burden. It states simple updates but fails to disclose side effects (e.g., impact on subcategories), permission requirements, or idempotency. Insufficient for a mutation tool.

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?

Single sentence, no wasted words. However, may be too brief for clarity on optional updates.

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 3 parameters (1 required), no annotations, and output schema present, description lacks prerequisites, error conditions, and behavior when fields are unchanged. For a modification tool, should provide more 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 coverage is 0%, so description does not explain parameters. Schema shows 'name' and 'icon' nullable with defaults, but description only says 'rename or change icon' without clarifying that omitting a field (null) leaves it unchanged. Adds minimal value beyond schema.

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 'Rename a category or change its icon' uses a specific verb ('rename'/'change') and resource ('category'), clearly distinguishing it from siblings like 'create_category' or 'delete_category'.

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 vs alternatives (e.g., 'create_category' for creation, 'delete_category' for removal). The description only states what it does, not usage context or prerequisites.

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