Modify an existing TestRail section by updating its name or description using the section ID. Use this to rename or edit section details without recreating it.
Update an existing section
| Name | Required | Description | Default |
|---|---|---|---|
| name | No | Optional new name | |
| section_id | Yes | The ID of the section to update | |
| description | No | Optional new 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 behavioral burden, and it discloses nothing: not whether omitted fields are left unchanged (partial update semantics), not whether the operation requires specific permissions, and not whether it is reversible. For a mutation tool with zero annotation coverage this is a significant gap.
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?
It is a single short sentence with no wasted words and the action is front-loaded. But the brevity reflects under-specification rather than disciplined conciseness, since nothing useful beyond the title is conveyed.
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 three-parameter mutation tool with no annotations and no output schema, the description is far too thin. It should at minimum clarify partial-update behavior and confirm the target resource, none of which is present.
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% – each of the three parameters is documented in the schema, including the optional new name and description and the required section_id. The description adds no meaning beyond the schema, so the baseline 3 applies.
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?
States a specific verb and resource ('Update an existing section'), so the action is unambiguous. However, it offers no differentiation from sibling mutation tools such as testrail_update_case, testrail_update_run, or testrail_update_project, leaving the agent to infer scope purely from the name.
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 on when to use this versus testrail_add_section or testrail_delete_section, nor any prerequisite or context. The agent must infer usage entirely from the tool name and parameter schema.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
