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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, so the safety profile is covered. The description adds the required auth scope (work_order_comments:write), which is genuinely useful context, but it omits the practical consequence of idempotentHint=false: repeated calls create duplicate comments.

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, no filler, with the action front-loaded ahead of the scope requirement. It is efficient, though perhaps slightly under-specified for the tool's complexity.

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 two-parameter create tool with a fully documented schema and no output schema, the definition covers the essentials (action, auth scope). It stops short of describing the created object's return or duplicate-comment behavior, leaving minor gaps.

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 both parameters (comment text and work_order_id with uuid format), so the schema already carries the semantics. The description adds nothing about parameter format or constraints beyond what is structured, so the 3 baseline 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 (Create) and resource (comment on a work order), which is unambiguous against the many sibling create_* tools. It does not explicitly differentiate from create_work_order, get_work_order_comment, or update_work_order_comment, but the name plus description make the intent obvious.

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?

No when-to-use guidance, no mention of prerequisites beyond scope, and no reference to the sibling tools (e.g., use get_work_order_comment to read existing comments). The agent must infer usage entirely from the name.

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