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

The readOnlyHint annotation already establishes this is a safe read. The description usefully clarifies that 'time entries' means technician hours and gives the REST endpoint, but says nothing about result size, pagination, or date-range behavior on a job that may have many entries.

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, zero filler, with the core purpose front-loaded and the endpoint reference following as supporting detail.

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 simple one-parameter read with annotations covering safety and no output schema, the description is essentially complete for correct invocation. Only minor return-shape context is absent, which is acceptable given the low complexity.

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% for the single job_number parameter, so the schema carries the semantics. The description adds no format or constraint detail (e.g. how job_number is obtained) beyond what the schema already states.

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 (List) and resource (time entries / hours logged by technicians) scoped to one job, and even the underlying endpoint. It is distinguishable from kickserv_log_time_entry (a write) and kickserv_list_job_notes, though it does not explicitly name which sibling to prefer.

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 implied by the name and description — you call this to read time entries for a known job — but there is no explicit statement of when to use it versus kickserv_log_time_entry or kickserv_list_jobs, and no prerequisites or exclusions are given.

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