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

No annotations are provided, so the description carries full burden for behavioral disclosure. 'Get test plan details' reveals nothing about permissions needed, rate limits, response format, pagination, error conditions, or whether this is a read-only operation. For a tool with no annotation coverage, this description provides essentially zero behavioral context.

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 maximally concise at three words with zero wasted text. It's appropriately sized for such a simple statement, though this conciseness comes at the cost of being under-specified rather than efficiently informative.

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 no annotations, no output schema, and a description that provides only basic purpose, this is incomplete for a retrieval tool. The agent needs to know what 'details' includes, the response format, authentication requirements, and how this differs from 'list_test_plans'. The description fails to provide necessary context for effective tool selection and invocation.

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?

With 100% schema description coverage, the input schema already documents both parameters thoroughly. The description adds no additional parameter semantics beyond what's in the schema - it doesn't explain parameter relationships, provide examples, or clarify edge cases. The baseline score of 3 reflects adequate but minimal value addition given complete 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 'Get test plan details' is a tautology that essentially restates the tool name 'get_test_plan'. It provides a basic verb+resource but lacks specificity about what 'details' includes or how this differs from sibling tools like 'list_test_plans'. The purpose is vague and doesn't distinguish this retrieval tool from alternatives.

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. There's no mention of prerequisites, when-not-to-use scenarios, or explicit alternatives like 'list_test_plans' for browsing versus 'get_test_plan' for detailed retrieval. The agent receives zero usage context beyond the tool name.

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