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

Beyond the annotations (readOnlyHint=false, destructiveHint=false, openWorldHint=true), it discloses that a human reads submissions and that repeating the same complaint does not create a new record but increments a counter — a genuine non-obvious side effect. It does not say what a successful submission returns, but there is no output schema, so that gap is modest.

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?

Front-loaded with the scope disambiguation in capitals, then usage triggers, then content requirements, then the repeat-complaint behavior. Every clause carries information an agent needs; nothing is padding.

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 4-parameter tool with full schema coverage and annotations covering the safety profile, the description supplies the missing usage and content guidance. The only unaddressed point is what the agent gets back on success, which is minor given the absence of an output schema.

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 coverage is 100%, so the baseline is 3; the description earns an extra point by adding real meaning — it tells the writer what 'body' must contain (tool name, what was called, what was expected, what came back), reinforcing the schema's terse field hints.

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 opening line names the resource precisely — feedback about this server — and explicitly excludes the domain-focused scope of its siblings (check_domain, whois_domain, dns_records). An agent can immediately tell this is the meta/feedback channel rather than a lookup tool.

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?

It enumerates concrete triggers: a tool behaved contrary to its description, a parameter or response field was missing, a refusal came without a reason, or the description was unclear. The 'not about domains' clause acts as an explicit exclusion, routing domain issues to the sibling tools.

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