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

Annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false, and openWorldHint=false, so safety profile is covered. The description adds real value by explaining that the action is already fixed server-side and is not re-specified by the caller, which is why the payload is only a reference. It does not disclose irreversibility, permission requirements, or confirmation expiry behavior, which matters for a destructive operation.

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?

One sentence, front-loaded with the core action, with examples appended rather than leading. Zero wasted phrasing and nothing needed is buried.

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 tool whose annotations and schema cover most structured detail, this is close to sufficient. However, with no output schema and a destructive effect, the description leaves open what happens on success (is the resulting resource returned?), on an expired or already-consumed confirmation, and whether idempotent replay returns the same result.

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 0%, so the single confirmationId parameter has no structured documentation at all. The description partially compensates by indicating the ID originates from a confirmation_required response, which tells the agent where the value comes from. It says nothing about constraints (32-128 chars), expiry, or reuse, which the schema cannot convey either.

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 ('Execute') on a specific resource ('the exact server-stored action from a confirmation_required response') and gives concrete examples (publishing a map, granting access). An agent can distinguish this from direct mutation tools like map_publish or resource_share_grant, since those are the actions this one confirms. It does not name the counterpart cancel_action, so sibling differentiation is implied rather than explicit.

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 trigger condition is precise: only call this with an action carried in a confirmation_required response. That is a clear usage context an agent can act on. It does not say when to decline in favor of cancel_action, nor what to do if the confirmation is stale, so it stops short of full alternative routing.

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