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

Annotations already declare destructiveHint=true and idempotentHint=false, so the safety profile is partly covered. The description adds that MCP approval requirements are configurable by the org admin and that business workflow approvals always apply, which is genuine extra context, but 'exact-change review' is vague and it never states what is destroyed or whether removal is reversible.

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 with the destructive action front-loaded and the approval caveat second. The second sentence is slightly abstract, but nothing is wasted padding.

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?

An output schema exists, so return values need no explanation, and annotations cover the destructive/idempotency profile. The main remaining gap is identifying the meaning of the 'id' argument, which is missing from both schema and description.

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?

There is a single required parameter 'id' with 0% schema description coverage; the schema supplies a UUID format and pattern but never says whether this is a budget approver ID, a user ID, or a budget ID. The description gives no parameter guidance at all, so it fails to compensate for the coverage gap.

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 names a specific verb and resource ('Remove a budget approver'), which is unambiguous and clearly separable from sibling names like add_budget_approver and list_budget_approvers. It does not explicitly contrast itself with those siblings in prose, so it falls short of a 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 phrase 'after exact-change review' implies a precondition, but no alternative tools are named and no explicit when-not guidance is given. An agent can infer this is the remove counterpart of add_budget_approver, but must do so on its own.

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