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

With no annotations provided, the description carries full burden but lacks behavioral details. It mentions returning 'a list of clients with their IDs and names', which gives some output context, but doesn't disclose critical traits like pagination, rate limits, authentication needs, or error handling. This is inadequate for a tool with no annotation coverage.

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 concise and well-structured in two sentences: the first states the purpose and context, the second specifies the return format. There is no wasted text, and it's front-loaded with the main action. However, it could be slightly more efficient by combining ideas.

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 (one optional parameter, no output schema, no annotations), the description is minimally complete. It covers the basic purpose and return format, but lacks details on usage guidelines and behavioral transparency, which are needed for full context. It's adequate but has clear gaps.

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 adds no parameter-specific information beyond what the input schema provides. Since schema description coverage is 100% (the 'search_text' parameter is fully documented in the schema), the baseline score of 3 applies. The description doesn't compensate with additional semantics, but doesn't need to given the high schema coverage.

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 tool's purpose: 'Search for clients to use in timesheets' specifies the verb (search) and resource (clients), with the context of timesheets. It distinguishes from siblings like list_categories or list_projects by focusing on clients, though it doesn't explicitly differentiate from other list_ tools beyond the resource type.

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 minimal guidance: it mentions 'to use in timesheets' which implies a context, but offers no explicit when-to-use rules, alternatives, or exclusions. For example, it doesn't clarify if this should be used before creating a timesheet versus other client-related operations, leaving usage vague.

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