categorize_transaction

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Quick categorization' and does not mention whether existing categories are overwritten, whether the operation is idempotent, what permissions are needed, or what side effects occur. This is severely inadequate 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?

The description is extremely short and front-loaded, but it is more under-specified than appropriately concise. The word 'Quick' adds little value, and the phrase mostly restates the tool name without providing meaningful context.

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 mutation tool with no annotations and no output schema, this one-liner fails to explain operational behavior, return values, or how it differs from bulk/automated categorization. While the schema covers the parameters, the description lacks essential context for an agent to invoke it confidently.

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?

The input schema provides 100% coverage with descriptions for both parameters (transactionId and category), so the schema already documents the parameter meanings. The description adds no additional semantic value beyond what the schema provides, warranting the baseline score.

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 clearly identifies the action (categorize) and the object (a transaction). However, it doesn't explicitly distinguish itself from sibling tools like bulk_categorize or auto_categorize_all beyond the vague word 'Quick.'

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 bulk_categorize, auto_categorize_all, or update_transaction. The intended single-transaction scope is only implied by the tool name and the word 'Quick.'

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