list_suites

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

The description discloses that project_id defaults to TESTRAIL_PROJECT_ID from env when omitted or 0, providing key behavioral context. However, no annotations exist, and the description doesn't confirm read-only or safety aspects.

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 sentences, front-loaded with the action and parameter default. No extraneous information; every word earns its place.

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 simplicity (one optional parameter) and the presence of an output schema, the description covers the essential behavior. Could mention what suites are returned (e.g., all or filtered), but not a major gap.

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 description coverage is 0%, but the description adds crucial meaning: project_id defaults to env variable when omitted or 0. This clarifies parameter behavior beyond the schema definition.

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 'List suites under a TestRail project,' specifying the verb and resource. It distinguishes from sibling tools like list_projects, list_runs, and list_sections by focusing on 'suites'.

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 like search_test_cases or list_runs. The description doesn't mention when not to use it or provide context for selection.

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