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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not mention side effects, authentication requirements, error scenarios (e.g., missing ID), or any other behavioral traits beyond the basic fetch operation. This is insufficient for an agent to understand the tool's full impact.

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, short sentence that is front-loaded with the verb and resource. Every word serves a purpose, and there is no unnecessary information. It is appropriately concise for a simple retrieval tool.

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 one parameter and no output schema, the description is adequate for a basic retrieval but lacks completeness. It does not explain the return format, error handling, or provide any additional context that would help the agent use it effectively, especially compared to the sibling tools. It meets the minimum but has gaps.

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 for parameters, so the description must add meaning. However, it only repeats 'by id' without explaining the format, constraints, or expected values of the 'id' parameter. This adds little value beyond what the schema already provides.

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 verb 'Fetch' and specifies the resource 'knowledge entry' and the method 'by id', clearly distinguishing from siblings like kb_search (which searches without a specific id) and kb_compare. It leaves no ambiguity about what the tool does.

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 does not provide any explicit guidance on when to use this tool versus alternatives, such as kb_search or kb_compare. The context is implied (use when you have an ID), but no direct comparison or exclusion is stated, making it less helpful for an AI agent to decide between tools.

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