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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the safety profile is covered. The description adds little beyond the word 'Remove,' which restates the destructive nature. It does not contradict annotations, and the bar for added behavioral disclosure is lowered by the annotations.

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. The core action is front-loaded and the practical id-source hint follows immediately. Every word earns its place.

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 two-parameter delete tool, the description provides the essential information: what is removed and where to get the identifier. The destructive annotation covers the main risk. A brief note on permanence or return value would make it fully complete, but nothing critical is missing.

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?

Input schema coverage is 100%, with both parameters documented ('Site ID' and 'Primary key of the added service'). The description essentially repeats the id guidance already present in the schema, so it adds minimal value beyond the structured field descriptions.

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 specific verb and resource: 'Remove a PCP service from a site.' This clearly identifies the action and target, and the reference to the primary key from list/create distinguishes this delete operation from related site-PCP tools like update_site_pcp_service or get_site_pcp_service.

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 gives clear operational guidance: use the primary key returned by list_site_pcp_services or create_site_pcp_service. This tells the agent where to obtain the required id. It does not explicitly name alternatives or when-not-to-use scenarios, but for a delete tool the usage context is sufficiently clear.

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