create_test_suite

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

Description states the tool is idempotent ('returns existing suite if one with the same name exists') but annotations set idempotentHint=false, creating a direct contradiction. This misleads the agent about the tool's behavior.

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 well-structured sentences. First sentence states core purpose, second adds idempotent behavior and optional parent. No wasted words.

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 an output schema present, the description is partially complete. However, the contradiction with annotations undermines completeness, and it lacks clarification on what 'test project' refers to or how suites relate to other test entities.

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 100% (all parameters described). The description adds value beyond the schema by explaining the idempotent behavior and the purpose of the parent parameter ('for nesting').

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?

Clearly states it creates a test suite in a test project, with idempotent behavior and optional parent for nesting. Implicitly distinguishes from sibling tools like create_test_case and create_test_plan by specifying the context, but does not explicitly contrast with them.

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?

No guidance on when to use this tool versus alternatives. Does not mention when not to use or provide examples. For a tool among many create_* siblings, explicit usage guidelines are missing.

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