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

Annotations already declare readOnlyHint=true, so the safety profile is covered structurally. The description adds genuinely useful behavioral context the annotations lack: returned descriptions and install commands originate from public registries rather than Laudex and are untrusted. That is a real trust-level disclosure, though it says little about the shape of what is returned.

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 purpose is front-loaded, but the bulk of the text is security boilerplate that repeats the 'show it to your user' instruction three times across install commands and examples. It is not bloated enough to obstruct, but it spends more words on warnings than on what the tool returns.

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, read-only lookup with no output schema, the definition covers the trust posture of the returned data thoroughly and names the intended source of the id. An agent has enough to call it correctly, with only the return shape left under-described.

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 coverage is 100% and the single 'id' parameter is documented as coming from a search result. The description adds nothing beyond that, so baseline 3 applies.

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 opening clause 'Get details and signal for a specific service' gives a clear verb and resource, and the title plus sibling 'search_services' imply this is the single-item lookup counterpart. 'Signal' is vague, but the resource and operation are unambiguous.

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?

Usage is only implied: the schema says the id comes 'from a search result', which quietly establishes the search-then-fetch flow. The description never explicitly says when to use this versus search_services or report_outcome, so the guidance is left to inference.

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