create_test_suite

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=true, so the safety profile is covered structurally. The description adds workflow context (nesting, then populate with work items) but says nothing about permissions, whether names must be unique within a plan, or what happens on duplicate creation — notable for a non-idempotent create.

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?

Two short sentences, zero waste: the creation scope is front-loaded and the follow-up action is a single clause. Nothing redundant with the name or title.

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 4-parameter create tool with annotations and no output schema, the description covers scope, nesting, and the next step in the workflow. The remaining gap is that it doesn't indicate the created suite's identifier is returned, which an agent needs to chain into set_test_suite_work_items.

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 coverage is 50%: name and testPlanId are undocumented in the schema, and the description only implies testPlanId via 'in a test plan' and elaborates parentId via nesting. The type enum (Custom/Dynamic/Tree) is left entirely to the schema's 'Default Custom' note, so the description adds marginal meaning only.

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?

Specific verb+resource: 'Create a test suite in a test plan', with the scoping detail that it can be top-level or nested under parentId. It implicitly separates itself from the sibling set_test_suite (update) and names set_test_suite_work_items as the downstream tool, though it doesn't state its distinction from those siblings outright.

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?

Gives clear context for use — inside a test plan, optionally nested via parentId — and prescribes the follow-up step with set_test_suite_work_items. It stops short of explicit when-not guidance or prerequisites (e.g., whether the parent suite must already exist).

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