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

The description frames the tool as producing suggested tags and deferring saving to save_taste_tags or update_personal_tag, which implies a non-destructive analysis step. This conflicts with destructiveHint=true in the annotations, so the description contradicts the declared safety profile.

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?

A single front-loaded sentence with no wasted wording. The parenthetical adds useful next-step routing without bloating the definition.

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?

An output schema exists, so return values need not be explained, but the definition still omits the meaning of lang and fails to explain the destructive behavior implied by destructiveHint=true. For a destructive-flagged tool, that is a material 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?

The only parameter is optional lang with an enum, and schema description coverage is 0%. The description never mentions lang or what language selection affects, so it does not compensate for the missing schema documentation.

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: analyse ratings into suggested personal tags. It names save_taste_tags and update_personal_tag as downstream alternatives, which helps distinguish next steps, though it does not clearly differentiate from get_my_taste.

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 a subscriber-only context and tells the agent what to do with the suggested tags afterward. It does not explain when to choose this tool over analysis-related siblings such as get_my_taste, nor when not to use it.

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