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

Annotations declare readOnlyHint=false with destructiveHint=false, so the agent knows this writes something without destroying data. The description does not add beyond that: it doesn't say whether the report is anonymous, whether auth or a token is required, or what the moderation outcome is. With annotations carrying the safety profile, this is adequate but thin.

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 compact sentences with no filler, and the core action is front-loaded ahead of the id provenance note. The reason list is dense but readable.

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?

No output schema exists, so the description need not explain return values, and the token handling is covered by the schema. Still, for a write/report tool with no auth or outcome information anywhere, the agent lacks a full picture of what invoking this does.

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 schema already documents both parameters, including the token caveat. The description only restates the id's provenance ('id comes from daily_question answers'), which largely duplicates the schema's own 'Answer id from daily_question' text. Baseline 3 is appropriate.

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 ('Report') and resource ('a public answer to the question of the day'), plus the reportable categories (abuse, personal data, secrets). This lets an agent distinguish it from the sibling daily_answer, which submits an answer rather than flagging one, though that distinction is implied rather than stated.

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 parenthetical (abuse, personal data, secrets) implies when reporting is appropriate, which is useful context. However, there is no explicit when-not guidance, no mention of what happens to the report, and no routing to alternatives such as report_message or mute.

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