webmaster_manage_prepare

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

Annotations declare the safety profile (not read-only, not destructive, not idempotent), and the description usefully adds that the approval is bound to principal, account and the exact request, and that no network write occurs. It does not say what happens to a stale or superseded approval, nor how long it stays valid.

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?

A single dense sentence with the action front-loaded and the crucial 'nothing is sent' guarantee trailing. No filler, though the parenthetical arg list slightly interrupts the flow.

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 not be described. But with a thin generic-object schema at 0% coverage, the description should clarify what an approval yields (e.g., an id needed for apply) and how the prepare/apply/reconcile trio relates; it stops short of that.

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% and 'args' is an untyped generic object, so the description's enumeration of its sub-keys (ids, query, body, csv) is genuinely additive. However, the required 'operation' parameter is left completely unexplained and the accepted values for it are given nowhere.

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 verb+resource are precise: 'Open an approval for one allowlisted Webmaster write/upload.' The clause 'nothing is sent' cleanly separates it from webmaster_manage_apply, though neither that sibling nor webmaster_manage_read/reconcile is named explicitly.

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 prepare-before-apply workflow is implied by 'Open an approval ... nothing is sent,' but the description never states when to call this instead of webmaster_manage_apply or webmaster_manage_reconcile, nor what prerequisite (allowlisting) must hold first.

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