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

No annotations are provided, so the description carries the full burden. It mentions the tool returns 'summary information for each timesheet', which adds some behavioral context about output format. However, it lacks details on permissions, rate limits, pagination, or error handling, which are important for a read operation with user-specific data.

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 two sentences, front-loaded with the core purpose and followed by output details. Every word earns its place with zero waste, making it highly efficient and easy to parse.

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's low complexity (2 parameters, no nested objects) and 100% schema coverage, the description is adequate but incomplete. It lacks an output schema, and with no annotations, it should provide more behavioral context (e.g., authentication needs, data scope) to fully guide the agent.

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 description coverage is 100%, with both parameters ('start_date', 'end_date') fully documented in the schema. The description adds no additional parameter semantics beyond implying date-range filtering, so it meets the baseline of 3 where the schema does the heavy lifting.

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 specific action ('List timesheets'), target resource ('timesheets'), and scope ('for the current user within a date range'), distinguishing it from siblings like 'get_timesheet' (single) and 'create_timesheet' (write). It precisely communicates what the tool does without ambiguity.

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 usage for retrieving timesheets within a date range, but does not explicitly state when to use this tool versus alternatives like 'get_timesheet' (for a single timesheet) or other list tools (e.g., 'list_projects'). No exclusions or prerequisites are mentioned, leaving some context for the agent to infer.

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