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

The annotation only declares destructiveHint=true; the description adds real behavioral context by labeling this a WRITE, flagging the internal-id vs customer-number pitfall, and disclosing the underlying POST endpoint. It still omits whether the response returns a new job id, permission requirements, or duplicate-handling behavior.

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?

Three short sentences, front-loaded with the WRITE verb and the tool's purpose, with no filler. Slight redundancy with the schema descriptions on customer_id/job_type_id keeps it from a 5.

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 10-parameter create tool with no output schema, the description covers purpose and ID sourcing but omits auth/permission expectations and any mention of what is returned (e.g. the new job id). It is workable but leaves an agent guessing about the post-call workflow.

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 the schema already documents all 10 parameters, and the description's notes on customer_id, job_type_id, and estimate largely restate the schema descriptions. The endpooint reference is the only genuinely additive detail, so baseline 3 is right.

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 description opens with a precise verb+resource ("create a job (work order) for a customer") and clarifies the domain term (work order). It also names the sibling used to source a required ID (kickserv_get_customer), which lets an agent distinguish it from read/update siblings at a glance.

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 explains how to source the required IDs and what the `estimate` flag does, which is useful context. However, it gives no explicit when-to-use or when-not-to-use guidance (e.g. vs kickserv_create_task or kickserv_update_job), leaving the routing decision to inference.

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