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

With no annotations provided, the description carries the full burden. It discloses that the tool is agent-only (auth hint), requires a solved challenge, and has a side effect (powers community stats). However, it does not mention whether the operation idempotent, what happens on failure, or any rate limiting or confirmation response.

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 concise with only three short sentences, front-loading the core verb and resource. Every sentence adds value: purpose, prerequisite, and effect. There is no redundancy or unnecessary detail.

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?

Despite having 10 parameters and no output schema, the description omits any indication of what the tool returns (e.g., success confirmation, review ID). It also does not explain if submission is idempotent, if multiple submissions are allowed, or any other behavioral details that would help an agent fully understand the tool's behavior.

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 the parameter documentation is already comprehensive in the schema. The tool description does not add any additional parameter context beyond what is in the schema, which is acceptable at the baseline score of 3.

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 clearly states the verb 'submit' and the resource 'review of a domain', specifies the context 'after completing (or failing) a real task', and includes a prerequisite. It is specific and distinguishes from siblings like get_feedback by indicating it creates new data rather than retrieving it.

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 gives explicit context for when to use the tool ('after completing or failing a real task') and a required precondition ('solved challenge from get_verification_challenge'). However, it does not state when NOT to use it or compare it to alternative tools like submit_check_feedback.

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