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

Annotations already disclose destructiveHint=true, idempotentHint=true, readOnlyHint=false, and that this is a closed-world operation. The description adds auth context beyond the annotations by naming the required scope, which is genuinely useful for invocation. It does not mention cascade effects or behavior when the ID is absent, keeping it at 4.

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, prerequisite second. No filler, no restatement of the title, every clause carries information.

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 full annotation coverage and no output schema, the description plus annotations tell the agent everything needed to invoke it correctly: what it does, what it targets, and the required scope. Only edge-case behavior (missing ID, dependent records) is unaddressed.

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% and the single parameter is already documented as a UUID 'Vendor-site assignment ID'. The description's 'by ID' phrasing adds nothing beyond the schema, so the baseline of 3 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 and resource ('Remove a vendor-site assignment by ID'), which is unambiguous and readily distinguished by name from the get/create/list vendor-site-assignment siblings. It does not explicitly name an alternative or contrast scope, so it stops short of 5.

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 a prerequisite ('Requires vendor_site_assignments:write scope'), which is useful, but offers no when-to-use framing or alternatives (e.g. use get_vendor_site_assignment to look it up first, or bulk operations for multiple deletions). Usage is implied by the name rather than stated.

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