list_timesheet_entries

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

No annotations are provided, so the description must carry the full burden. It states the tool lists entries with optional filters and pagination, which is adequate for a simple read operation. However, it does not disclose any behavioral traits beyond what is inferred, such as default ordering or response format. There is no contradiction with annotations.

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 sentence of 14 words, concise and front-loaded with the main action. It contains no superfluous information and efficiently communicates the purpose.

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 no output schema and no annotations, the description is somewhat minimal. It covers the inputs well but does not describe the return format, default behavior, or any edge cases. For a list tool with 5 optional parameters, the description is adequate but could be more complete in explaining what the response looks like.

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% for all 5 parameters, each with clear descriptions. The description adds a summary of parameter categories (date range, project, pagination) but does not provide additional meaning beyond what the schema already offers. Baseline score of 3 is appropriate.

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 specifies the verb 'List', the resource 'timesheet entries', and the scope 'with optional filters for date range, project, and pagination'. It distinguishes from sibling tools like get_timesheet_entry (single entry) and create/update/delete (mutations).

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 implicitly states when to use by listing optional filters, suggesting it is for listing entries with filtering. However, it lacks explicit guidance on when not to use, such as recommending get_timesheet_entry for a single entry or list_projects for projects. Still, the context from sibling tool names helps.

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