create_timesheet

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

The description adds no behavioral context beyond the annotations. It does not mention that a create operation persists, that repeated calls create multiple entries (consistent with idempotentHint=false), or any side effects like requiring existing user IDs or business activities. It is not contradictory, but it provides zero additional 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 very short, but it is under-specified rather than effectively concise. Every word restates the tool name, providing no informative content. A concise description should communicate essential information in few words, but this one communicates only what can be inferred from the name itself.

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 complexity of 13 parameters, a nested tracking object, no output schema, and numerous sibling timesheet tools, the description is severely incomplete. It fails to explain the purpose of required fields, the tracking format options, or what a successful creation returns. An agent cannot invoke this tool correctly with only this description.

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 contains no parameter information. With 13 parameters and only 54% schema description coverage, the description was expected to clarify key fields like tracking format (range vs duration), allowable_bill semantics, or required references. It does not, adding no value beyond the 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 'Create timesheet' is a direct tautology of the tool name and annotation title. It states a clear verb+resource but adds no specificity about what a timesheet is, what it contains, or how it differs from similar operations like update_timesheet or get_timesheet. This fails to distinguish the tool from its siblings.

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?

There is no guidance about when to use this tool versus other timesheet-related tools (e.g., update_timesheet, delete_timesheet, search_timesheets). The description does not mention any context, prerequisites, or alternative tools, leaving the agent without criteria for selection.

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