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

The description states the tool 'returns' information, implying a read-only operation, but the annotations declare readOnlyHint=false. This contradicts the description, creating confusion about whether the tool has side effects. No additional behavioral context is provided.

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, focused sentence that states the verb, resource, and the key identifier. No wasted words, and the API endpoint is included for reference.

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 get-by-ID operation, the description covers the essential purpose. However, it does not specify what 'detailed information' includes, and the annotation contradiction undermines completeness. Given the simplicity, a score of 4 is appropriate.

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 schema already fully describes the single parameter db_cluster_id as the required ID. The description's mention of 'by its ID' adds no new semantic value beyond the schema, so baseline 3 applies.

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 it returns detailed information about a specific database cluster by its ID, using the exact REST endpoint. It is distinct from sibling tools like list_database_clusters by focusing on a single cluster.

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 implies usage for retrieving a single cluster by ID, but it does not explicitly mention alternatives or contrast with list/get other resources. Context is clear but no exclusions or comparisons to sibling tools are provided.

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