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

Annotations already declare destructiveHint=true and openWorldHint=false, so the safety profile is covered; the description adds real value by bounding the blast radius, stating that contained prompts and their scores are untouched. It stops short of saying whether the rename is reversible or whether the old name is retained anywhere.

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 short sentences, zero filler, with the action stated first and the side-effect caveat immediately after. Nothing is repetition of the title beyond the necessary verb+resource.

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-required-parameter mutation with full schema coverage and no output schema, the description covers the action and the scope of impact. It could go further by noting what a successful call returns or how name collisions are handled, but nothing essential is 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 all three parameters (domain_id, topic_id, name) are already documented with format and length constraints. The description adds no format, scoping or constraint detail beyond what the schema provides, which is the expected baseline.

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?

"Rename a prompt topic" gives a specific verb and resource, and the second sentence scopes the change to the name only. Against siblings like delete-prompt-topic, create-prompt-topic and move-prompt-to-topic the intent is inferable from the verb, though no sibling is named explicitly.

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 rename framing implies when to reach for this rather than create/delete/move, but there is no explicit when-to-use or when-not-to-use statement and no mention of prerequisites such as needing write access to the domain.

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