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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=true, so the safety profile is covered. The description adds the REST endpoint and the notion that related records can be included, but never says which relations are available or what happens if include is omitted.

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 resource and scope. The 'GET /maintenance-jobs/{id}' tail is mildly redundant but a cheap, useful routing hint for an API-shaped toolset.

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 tool with full schema coverage and annotations, the core is covered. The unexplained 'include' reference is a real gap: an agent cannot tell how to request related records, or whether omitting it returns only the bare job.

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 single parameter has 100% schema coverage including the UUID format and its source (street_list_maintenance_jobs), so the description adds nothing there. Worse, it references an 'include' parameter that does not exist in the input schema, which could lead an agent to pass an invalid argument.

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 ('One maintenance job by UUID') and implicitly distinguishes from street_list_maintenance_jobs by singular vs. list. Sibling differentiation is present but by implication rather than explicit naming.

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: an agent can infer this is the fetch-single-after-listing call, and 'with the related records you ask for' hints at an expansion use case. No explicit when-to-use/when-not, and no reference to the list tool or id source (that only appears in the schema description).

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