getSuites

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

The verb 'retrieves' implies a read-only, non-destructive operation, which is adequate for a tool with no annotations. However, it does not explicitly state safety, idempotency, authentication requirements, or potential side effects, leaving some ambiguity.

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 short, front-loaded, and bilingual, but the repetition of identical information in two languages slightly reduces conciseness. Every sentence earns its place, though a single language version would be more efficient.

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 absence of an output schema, the description should at least hint at the return format (e.g., list of suite objects). It also fails to mention any prerequisites, pagination, or limit considerations, leaving the agent with incomplete context.

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 schema provides 100% coverage for the single parameter (projectId) with clear descriptions in English and Japanese. The description adds no additional meaning or constraints beyond the schema, meeting the baseline.

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 retrieves all test suites for a specified TestRail project, using a specific verb ('Retrieves') and resource ('all test suites'). This distinguishes it from sibling tools like getSuite (singular) and addSuite.

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 is provided on when to use this tool versus alternatives (e.g., getSuite for a single suite). The description implies usage when needing all suites for a project, but lacks exclusions or context-specific advice.

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