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

readOnlyHint=true already tells the agent this is a safe read, so the description only needs to add context. It adds the 62-day range limit, but that is also repeated in the max_date schema description, and it says nothing about permissions, scoping to the caller's own timesheets, or result volume beyond what the schema's limit/offset already convey.

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?

A single front-loaded sentence with a content enumeration and the key constraint, followed by a short PATH note. Nothing is padded, though the trailing 'GET /timesheets' adds little an agent can act on.

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?

With no output schema, the description usefully inventories the timesheet fields an agent can expect, and pagination is covered by the schema's limit/offset descriptions. It is nearly complete for a list tool; only explicit sibling routing and scoping notes are missing.

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%, so every parameter (limit, offset, status, user_id, department_id, min_date, max_date) is already documented in the schema. The description adds only the enumeration of returned fields and restates the 62-day constraint, which is the expected baseline when 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?

States a specific verb and resource ('List timesheets') and enumerates the returned content (clock in/out, breaks, total, status, wage, surcharges), so an agent knows exactly what it gets back. The scope constraint (date range max 62 days) is also stated. It does not explicitly distinguish itself from the singular shiftbase_get_timesheet or shiftbase_list_clocked_in, so it stops short of a 5.

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 62-day maximum date range is a real usage rule, but there is no explicit when-to-use guidance, no named alternative, and no statement of when to prefer shiftbase_get_timesheet or shiftbase_list_clocked_in over this tool. Usage is only implied by the date-range and status/user/department filters.

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