bulk_categorize

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

With no annotations provided, the description bears full responsibility for disclosing behavior. It only states the action and scope, providing no detail on side effects, atomicity, overwrite semantics, error handling, or permission requirements. This is a significant transparency gap 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 a single, front-loaded sentence with no wasted words. It delivers the core purpose efficiently.

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?

The tool is simple with only two parameters and no output schema, but the description omits important behavioral context such as return values, partial failure handling, or whether the operation is atomic. Given the lack of annotations, this leaves the agent with unanswered questions, though the low complexity keeps it from being severely incomplete.

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 100%: both 'transactionIds' and 'category' have descriptive text. The tool description itself adds no further meaning beyond the schema, so the baseline score of 3 applies.

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 'Categorize multiple transactions at once' clearly identifies the verb (categorize), the resource (transactions), and the multi-item scope. It effectively distinguishes itself from the sibling 'categorize_transaction' tool by highlighting that it handles multiple transactions at once.

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?

The description implies use for bulk operations ('multiple transactions') but does not explicitly state when to use it over alternatives, nor provide exclusions or prerequisites. It is minimally sufficient but lacks direct comparison to singular categorization or other related tools.

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