create_time_registration

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 mentions creating a registration but does not describe the effect (e.g., whether it creates a draft, requires approval, or has side effects on timesheet status). It also lacks any mention of permissions or reversibility, leaving significant behavioral unknowns 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, efficient sentence that front-loads the tool's purpose and immediately provides a practical usage hint. It contains zero fluff and earns every word, making it ideal for quick agent comprehension.

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 tool has 6 parameters (3 required), no output schema, and no annotations, the description is too sparse for full contextual completeness. It only addresses the prerequisite of finding TaskID, but omits details about the registration workflow, potential errors, or interaction with timesheet submission. The agent is left without important context about the tool's role in the broader time-registration process.

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 schema provides 100% coverage with descriptions for all parameters, so the baseline is 3. The tool description adds no extra parameter context beyond the schema, merely stating the purpose and the need for TaskID. It does not add value in clarifying format, defaults, or relationships between parameters.

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 states the tool's action ('Create a new time registration') and its target ('on a task'), distinguishing it from update/delete operations. It also names a critical prerequisite (search_tasks to get TaskID), which leaves no ambiguity about the tool's role.

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 explicitly instructs the user to call search_tasks first, providing a clear contextual step for correct usage. However, it does not explicitly contrast with alternatives like update_time_registration or delete_time_registration, leaving some implicit inference about when not to use this tool.

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