update_reviews

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

Annotations indicate the tool is not read-only, not destructive, and not idempotent, but the description adds no additional context beyond 'submits.' It does not explain whether submitting a second review replaces the first, whether it fails on already submitted reviews, or any side effects. The description fails to complement the annotations meaningfully.

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 description is a single sentence, making it concise. However, conciseness at the expense of necessary detail is not ideal. It is appropriately front-loaded but lacks the substance needed for an effective tool 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?

Given the tool has 5 parameters (4 required) and an output schema, the description is far too sparse. It does not explain return values, parameter constraints (e.g., enum options), or how the output relates to the submission. The context provided is insufficient for an agent to invoke the tool correctly.

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 input schema has 0% description coverage, and the tool description does not elaborate on any parameter. It only vaguely mentions 'for a specific pull request,' leaving the purpose of 'event,' 'body,' and required fields entirely unexplained. The description adds no value beyond the schema.

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 clearly states 'Submits a review for a specific pull request,' which provides a specific verb and resource. However, the tool name 'update_reviews' suggests modifying an existing review, while the description implies submission (creation). This slight mismatch prevents a perfect 5, but the purpose is still clear.

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 description offers no guidance on when to use this tool versus alternatives, such as add_pr_comments or other review-related tools. No prerequisites or exclusion criteria are mentioned, leaving the agent to infer usage from context.

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