Add comment to test case

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

With no annotations provided, the description carries the full burden of disclosing side effects and safety. The phrase "as the logged-in user" hints that the comment is attributed to the current user, which is a behavioral trait, but it does not mention whether the comment is permanent, whether write permissions are needed, or what feedback is returned. This is minimal transparency for a mutating 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 (a single sentence), which is concise, but it is not well-structured for an agent. It starts with a code method name "TestCase.add_comment" rather than a plain-language verb phrase, and it omits key explanatory context. Every word is minimal but not sufficiently informative.

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 simple tool with two parameters and no output schema, the description still needs to explain the action's effect and any relevant context. It only provides a code reference and an auth note; it does not state that a comment is appended to a case, what the expected outcome is, or how it relates to case history. The description is incomplete for safe and correct invocation.

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 input schema already provides full documentation for both parameters (id as "Test case id" and comment as "Comment text"), so the schema description coverage is 100%. The description adds no additional parameter semantics, so a baseline score 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 title "Add comment to test case" clearly states the action and resource, and the description's "TestCase.add_comment" aligns with that intent. However, the description itself is a code method reference rather than a plain-language explanation, which may confuse agents unfamiliar with the Kiwi TCMS API. It does not explicitly say "Adds a comment to a test case," so the purpose is only implicitly clear.

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 tool versus alternative actions like adding tags or components, nor any mention of prerequisites. The only hint is "as the logged-in user," which implies authentication but does not explain when commenting is appropriate. This dimension is essentially unaddressed.

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