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

No annotations are provided, so the description carries the full burden. It usefully describes the rich return payload (score, history, communities, raw evidence), which is more than most descriptions offer, but it omits any mention of read-only safety, authentication, rate limits, or error behavior for nonexistent entities.

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?

One dense, front-loaded sentence plus a short routing clause. Every clause adds information about the return payload or valid input source, with no filler.

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 one-parameter lookup with no output schema and no annotations, the description gives a solid preview of return contents and input sourcing. It lacks behavioral details like mutation safety (though a get is implicitly read) and error handling for unknown names, leaving a minor gap.

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?

Schema description coverage is 100%, and the single parameter's schema already supplies the example and source (list_entities). The description repeats the example 'kubernetes' and source rather than adding new semantics like case-sensitivity, fuzzy matching, or format constraints.

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?

States a specific verb (retrieve full detail) and resource (one entity by name), and enumerates the return contents: composite score, score history, communities, and member evidence. It clearly distinguishes itself from siblings get_topic, list_entities, and list_signals by scoping to a single entity's full detail.

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?

Explicitly states that names come from list_entities, providing a clear prerequisite and directing the agent to the sibling that supplies valid inputs. It does not describe when to prefer get_topic or list_signals instead, so it falls short of full alternative guidance.

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