test_rename

Does 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 explicitly states that the operation 'updates the DB and the mirror file,' which is a meaningful side-effect disclosure beyond the simple rename semantics. However, it does not mention potential failures, uniqueness constraints, or reversibility.

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 a single compact sentence that front-loads the action and then adds the essential side-effect detail. There is no filler, redundancy, or unnecessary complexity.

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 two-parameter rename operation with no output schema, the description is largely sufficient: it identifies the resource, the operation, and the persistence effects. It does not state constraints like 'newName must be unique' or 'test must exist,' but those are reasonably inferable from standard rename semantics.

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%, and both parameters already have clear descriptions ('Name of the saved test' and 'New name'). The tool description adds no additional parameter-level meaning, so the baseline of 3 is appropriate.

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 specific verb ('Renames') and a clear resource ('a test in the library'), and even notes the underlying effect on the DB and mirror file. This distinguishes it from sibling tools like test_update or test_duplicate because the action is unambiguous.

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?

The description offers no guidance on when to use this tool versus alternatives such as test_update, test_duplicate, or test_delete. There are no exclusions, prerequisites, or preferred scenarios given; the only usage signal is the verb 'Renames,' which is implied rather than explicit.

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