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

Annotations declare readOnlyHint=false and openWorldHint=false, flagging a local write. The description adds that the submission is made on the user's behalf and that a reply requires contact info, which is useful context beyond the annotations. It does not say whether the request is idempotent, rate-limited, or what confirmation the submitter receives.

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?

Three short sentences: action, trigger condition, input expectation. Front-loaded with the purpose and no filler or repetition.

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 simple 3-parameter submission tool with no output schema, the description covers what it does, when to invoke it, and the expected input shape. Only the post-submission behavior (confirmation, error handling) is unaddressed, which is a minor gap.

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 schema already documents title, contact, and details. The description reinforces the expected shape ('One sentence title plus optional details') but adds no format or constraint detail beyond what the schema already carries.

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 ('Sends a feature suggestion or piece of feedback to the AnimeHunt team') plus the acting scope ('on the person's behalf'). This is clearly distinguishable from every sibling, all of which are read/library/review operations on titles.

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?

Gives explicit triggering conditions: 'Use when someone wishes the site did something it does not, or wants to report a problem.' No alternatives or exclusions are named, but no close sibling exists that would compete with this tool, so the omission is minor.

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