Create a section in TestRail to organize test cases by specifying project and section name, with optional suite, parent, and description.
Create a section
| Name | Required | Description | Default |
|---|---|---|---|
| name | Yes | Section name | |
| suite_id | No | Suite ID (for multi-suite projects) | |
| parent_id | No | Parent section ID | |
| project_id | Yes | Project ID | |
| description | No | Section description |

v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Create a section,' which is essentially the same as the tool name and gives no information about side effects, required project/suite context, permissions, or the shape of the result. This is minimally transparent for a mutation operation.
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 extremely short and front-loaded, with no wasted words. However, it is under-specified rather than efficiently comprehensive: it lacks any contextual or behavioral detail that would make the brevity genuinely useful.
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 that this is a creation tool with no annotations and no output schema, the description is too sparse. It does not explain how sections relate to projects or suites, whether parent_id is typical, or what the agent should expect after calling the tool. The schema helps with parameters, but the description leaves important operational context missing.
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 100%, so the schema already documents all five parameters clearly. The description adds no parameter-level meaning beyond what the schema provides, but it also does not need to compensate because the schema is complete.
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 uses a clear verb and resource: 'Create a section.' It communicates the core operation immediately and is distinct from sibling tools like add_suite or add_project due to the resource term. However, it does not clarify whether this is a top-level section or a nested/hierarchical section, which would help further disambiguate from tools like move_section.
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?
There is no guidance about when to use this tool versus alternatives such as update_section, delete_section, or move_section. The description implies it is for initial creation only, but it does not state prerequisites, when not to use it, or how it relates to parent sections or suites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
