get-link-by-suffix

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

No annotations are provided, so the description carries full burden. It states 'Look up', which implies a read-only operation, but does not disclose potential side effects, return format, authentication needs, error behavior, or whether the tool modifies anything. This goes beyond what the schema provides.

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 sentence that is front-loaded with the action and resource, containing no redundant words or restatements. It is maximally concise while still conveying the core purpose.

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?

The tool is a simple lookup operation, and the schema covers all parameters. However, with no output schema and no annotations, the description does not mention what is returned (e.g., the full link details) or any edge cases, leaving a slight gap in completeness despite the low complexity.

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 already provides 100% coverage for both parameters (suffix and project_id), including descriptions. The tool description adds no additional parameter-level detail, so the baseline of 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?

The description states a specific action ('Look up') on a specific resource ('Limelink dynamic link') with a specific lookup key ('suffix'), clearly distinguishing it from the sibling 'get-link-by-url' which uses a URL as the key.

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 when you have a suffix, but it does not explicitly mention when to use this tool versus the sibling 'get-link-by-url' or provide any exclusion guidance. The context of sibling names makes the distinction apparent, but it is only implied, not stated.

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