timeiq_expense_category_create

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

The description implies a write operation ('Create') but does not disclose any behavioral traits such as authentication requirements, side effects, error conditions, or idempotency. With no annotations, the description carries the full burden and fails to provide adequate transparency.

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 (6 words) but is under-specified. It is not concise in a positive sense because it adds no value beyond the tool name, wasting the opportunity to inform the agent.

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 lack of annotations, output schema, and parameter descriptions, the description is entirely incomplete. The agent receives no guidance on return values, error handling, or operational context, making the tool difficult to use correctly.

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 description makes no mention of any parameters. The input schema has 3 parameters (name, isActive, dry_run) with 0% schema coverage, so the agent is left to infer meaning solely from parameter names and types, which is insufficient.

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 'Create a new expense category.' is a tautology that merely restates the tool name. It adds no additional context or differentiation from sibling tools, which are distinguished by verb but the description does not provide any unique details.

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 usage guidelines are provided. The description does not indicate when to use this tool versus alternatives, nor does it list prerequisites, typical use cases, or scenarios where the tool would be inappropriate.

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