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

Annotations already declare non-read-only, non-destructive, non-idempotent, closed-world behavior, so the safety profile is covered. 'Runs at once' adds a genuine behavioral fact (synchronous, no async polling), but nothing is said about duplicate names, permissions, or side effects on existing prompts.

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 with no filler, and the core action is front-loaded. 'Runs at once' is terse to the point of being slightly cryptic, which keeps it just below a 5.

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 output schema, no parameter documentation, and only safety annotations, the description is too thin. An agent gets no information about return values, uniqueness constraints, or how the new topic relates to existing prompts.

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 0% across three parameters, so the description carries the burden and does not meet it. It never mentions name, project_id, or description, leaving their meaning and constraints (UUID format, 255/1024 length limits) undocumented in prose.

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 (add) plus resource (topic) and its purpose (grouping prompts under it), so an agent knows what gets created. It does not explicitly differentiate from the sibling rename_topic, which is the main clarity gap.

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 when-to-use guidance, no prerequisites (e.g. that project_id must reference an existing project), and no mention of alternatives such as rename_topic. The phrase 'to group prompts under' only implies context rather than stating it.

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