Apply an approved proposal

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

The annotations already declare destructiveHint=true and openWorldHint=true, so the agent knows this is a mutating, externally visible operation. The description adds the approval precondition and the failure conditions, which is real value beyond the annotations, but it never says what actually changes when the proposal is applied or whether the effect 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, front-loaded with the action, and every clause carries information about preconditions or failure modes. There is 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 destructive, irreversible-sounding mutation with no output schema, the definition covers when the call fails but leaves open what the return value is and what the side effects on orders, stock, prices, or refunds will be. Adequate to avoid misuse, but not complete.

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?

The schema coverage is 0% and the single required parameter proposal_id is never explained in the description. It does not say where the identifier comes from (e.g., a prior propose_* call or list_proposals), nor what the minLength constraint implies, so the description adds nothing over the bare schema.

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?

"Executes a proposal that a human has approved" gives a specific verb (executes) and resource (proposal) and implicitly separates this tool from the propose_* siblings and list_proposals. It stops short of naming an alternative, but the action is unambiguous.

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?

It states a clear precondition (only after human approval) and two negative conditions (pending/rejected proposals, read-only servers) that tell the agent when the call will not work. What is missing is any pointer to checking status via list_proposals before calling.

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