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

readOnlyHint=true already marks this as a safe read. The description usefully previews the returned fields (provider, price, duration) and the endpoint, but adds nothing about pagination, result size, or auth beyond the schema's default-UID note.

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 compact sentences plus an endpoint reference; the resource description and the create_job dependency are front-loaded 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 read-only list tool with fully documented params and no output schema, the description covers what is listed, example categories, and the downstream use, leaving only minor gaps like result ordering or pagination.

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%, so agency_uid, catered_to, and service_provider_uid are already documented in the schema. The description mentions providers and services but adds no syntax or format detail beyond structured fields, 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?

States a specific verb+resource ('List the services an agency offers or schedules'), gives concrete examples, and names what the resource enables downstream (create_job). An agent can distinguish it from siblings like hostfully_list_jobs or hostfully_list_properties.

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 ties the result to hostfully_create_job ('A service UID is what hostfully_create_job needs'), which implies when the tool is needed, but it never states explicit when-to-use vs. sibling alternatives or exclusions.

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