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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds value by mapping to the underlying endpoint (GET /job), confirming a non-mutating paginated collection read. However, it says nothing about pagination defaults, result caps, default sort order, or what happens when no filters are supplied — the operational traits an agent needs for a 17-parameter list call.

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 dense sentences: the first front-loads what is listed and what comes back, the second covers filtering and the endpoint mapping. No filler, no repetition of the title, and the return-field inventory is placed before the filter list where it is more useful.

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 17-optional-parameter read tool with full schema coverage and no output schema, the description covers purpose, return fields, and filterable dimensions adequately. Gaps are minor — no note on pagination limits, sorting defaults, or whether the response is a summary vs. full job record — but an agent could invoke it correctly from this plus the schema.

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 every parameter (including enum-ish status/type values, timestamp semantics, and page/limit bounds) is already documented in structured form. The description only restates the filter categories in prose and adds no syntax, format, or interaction detail beyond the schema. 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?

Specific verb + resource ('List jobs') with the domain subtypes spelled out (service calls, inspections, installs) and an enumeration of the fields returned (status, type, customer, location, owner, due date, estimated price). An agent can distinguish it from servicetrade_get_job by the plural/listing framing, though the description never explicitly names the single-record sibling.

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?

It says what can be filtered on ('Filter by status, type, location, customer, technician, due or completion dates'), which implies when the tool is appropriate — broad retrieval with narrowing criteria. But there is no explicit when-not guidance, no mention of the get_job alternative for single-record lookups, and no prerequisites stated. Usage is inferable rather than directed.

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