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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description still adds genuine value by disclosing the required write scope and the user-visible consequence that the technician's day loses the stop.

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, action first, with the effect and the auth requirement each packed into a single clause and no filler.

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 single-parameter delete with annotations covering the safety profile and no output schema, the definition supplies effect and scope requirements. It stops short of noting irreversibility or error behavior on an unknown ID, which are minor residual 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?

Only one parameter exists and schema description coverage is 100%, so the schema already documents the UUID id fully. The phrase 'by ID' adds no format or sourcing detail beyond that, making the baseline 3 correct.

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 and resource ('Delete a work order schedule entry by ID') and adds the real-world effect, removing the stop from the technician's day. Clear on its own, but it never explicitly contrasts with update_work_order_schedule or delete_work_order, so sibling routing rests on the name convention rather than the text.

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 operation, and one prerequisite is given ('Requires work_order_schedules:write scope'), but there is no explicit when-to-use/when-not-to-use guidance or reference to the update/create alternatives for rescheduling instead of deleting.

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