A4/5.0

Behavior3/5

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

With no annotations, the description carries the burden of disclosing behavior. 'Get' implies a read-only operation, but it does not explicitly state this or mention potential error conditions, authentication requirements, or rate limits. It does add a useful detail about the full instructions text being included, which suggests a possibly large response, but overall transparency is moderate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is front-loaded with the action and resource, and every word adds value. No filler or redundant content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple (one parameter) and has an output schema, so return values are documented. The description covers the core purpose and a notable detail (full instructions text). However, it lacks explicit read-only disclosure or failure scenarios, but given the tool's simplicity, it is largely complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has one parameter 'name' with no description (0% schema coverage). The description says 'Get one knowledge base's configuration,' implying that 'name' identifies which knowledge base to retrieve, but it does not explicitly define the parameter's format, uniqueness, or required nature beyond the schema's required flag. This adds some meaning but leaves room for ambiguity.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Get') and the resource ('one knowledge base's configuration'), and adds a distinguishing detail ('including the full instructions text shown to the model') that separates it from listing or searching knowledge bases. This is a specific and unambiguous purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use this tool: when you need the full configuration, including the instructions text, for a single knowledge base. This context differentiates it from list_knowledge_bases, which likely returns summaries. No explicit exclusions are stated, but the phrasing provides clear usage context.

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