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

No annotations are provided, so the description carries the full burden. It discloses the time-limited edit window, the 'your own review' restriction, and partial-update behavior ('omit fields'). This meaningfully clarifies mutation behavior beyond what the tool name implies.

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 short sentences, front-loaded with the main verb and object, then efficient statement of constraints. Every word earns its place with no redundancy.

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 mutation tool with 4 parameters and no annotations, it covers ownership, time limit, and update semantics. It omits return-value details, but that is not critical for an update tool. Minor gap regarding expected response or error cases, but otherwise adequate.

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 0%, but the description adds the key semantic that omitted fields are not changed. It doesn't enumerate the parameters, but the schema property names (body, title, rating, review_id) are self-explanatory. This partially compensates for the coverage gap.

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 description uses the specific verb 'update' with the resource 'your own review', clearly stating ownership and distinguishing it from post_review or other review-related tools. The 24-hour constraint and partial-update hint further narrow its scope.

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 explicitly states the 24-hour time limit, giving clear context on when the tool is valid. While it doesn't name alternative tools, the ownership restriction and time window define usage boundaries sufficiently.

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