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

With no annotations, the description carries the burden and does well: it discloses cost (free), the return shape (ok + case_id + status), and the progress-tracking mechanism (feedback_case_status or the GET URL). It does not mention auth requirements or rate limits, but for a free public feedback endpoint that gap is minor.

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 '[FREE]' tag and core action are front-loaded, then a bulleted parameter list follows, then return/polling info. Despite its length, every line earns its place because the schema provides no descriptions.

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 7-parameter tool with 0% schema coverage and no annotations, the description supplies everything needed to call it correctly: all parameter semantics, cost, return values, and the follow-up path. Nothing an agent needs 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 coverage is 0%, so the description must fully compensate and it does: it enumerates the allowed site values, the six kind values, message length bounds (10-4000), an endpoint path example, severity levels with a default, and the purpose of reporter/contact. This is exactly the meaning the bare schema lacks.

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 and resource ('File a bug report, docs correction, or payment problem ... get a case id back') and names the exact properties it applies to. An agent can distinguish it from the large sibling set, and the description explicitly routes follow-up to feedback_case_status.

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?

Clearly establishes when to use it (something is broken / needs correction) and removes a key decision barrier by stating it is free ('never costs money'). It also names the companion polling tool. It stops short of stating explicit exclusions or alternatives for submitting feedback elsewhere.

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