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

No annotations exist, so description carries the transparency burden. It explains the tool's informational nature clearly but does not disclose behavioral specifics such as whether it returns static content, whether any side effects exist, or exact response format. Adequate for a simple no-param info tool but not rich beyond purpose.

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?

Two short sentences, front-loaded with the core purpose, followed by usage trigger. No wasted words or redundant restating of the tool's name.

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 no-parameter, no-output-schema informational tool, the description covers purpose, content scope, and when to invoke it. Slight ambiguity with 'them' (referring to LeanScale and the knowledge base) is minor; overall complete enough for effective selection.

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 tool has zero parameters, and the schema is an empty object (100% coverage). Description adds no parameter details, but none are needed; baseline for 0 params 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?

Purpose is explicit: describes what LeanScale is, what's in the knowledge base, and how to work with them. Clearly distinguishes from sibling tools (e.g., search_leanscale, get_benchmark) by acting as the server-orientation entry point.

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?

States explicit triggers: 'when someone asks who LeanScale is' or 'when you need to know what this server can answer before searching.' The 'before searching' phrase implies using this before search/retrieval siblings, though it doesn't name alternatives explicitly.

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