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

With no annotations provided, the description carries full burden for behavioral disclosure. It states it retrieves 'full details' but doesn't specify what those details include, whether it's a read-only operation, authentication requirements, error handling, or rate limits. The description is minimal and lacks essential behavioral context for a tool that presumably accesses sensitive timesheet 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 a single, clear sentence with zero wasted words. It's front-loaded with the core purpose and efficiently communicates the essential action without unnecessary elaboration. This is an excellent example of conciseness.

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?

For a tool with no annotations and no output schema, the description is insufficient. It doesn't explain what 'full details' includes, the response format, or any behavioral aspects. Given the complexity of timesheet data and the lack of structured metadata, the description should provide more context about what information is returned and how to interpret it.

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 input schema has 100% description coverage, with the single parameter 'timesheet_id' clearly documented. The description adds no additional parameter semantics beyond what the schema provides (it only mentions 'by its ID' which the schema already covers). This meets the baseline score of 3 when schema coverage is high.

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 action ('Get full details') and resource ('a specific timesheet by its ID'), making the purpose immediately understandable. It doesn't explicitly differentiate from sibling tools like 'list_timesheets' or 'get_timesheet_defaults', but the specificity of retrieving by ID provides some implicit distinction.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention when to choose 'get_timesheet' over 'list_timesheets' for browsing multiple timesheets, or 'get_timesheet_defaults' for default settings. There are no prerequisites, exclusions, or context about appropriate use cases.

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