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

Annotations already declare destructive=true, openWorldHint=true and idempotentHint=true, and the description reinforces rather than contradicts them: it discloses the recipient-notification side effect (and cancellation risk) and explains the retry contract ('reuse the same preview, hash and confirmation reference after uncertainty'). It also details a recovery branch (missing custody permits allow receipt recovery but cannot authorize a new dispatch) that adds genuine behavior beyond the annotations.

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?

The commit action is front-loaded and the notification and retry facts are useful, but the wording is dense with internal jargon ('private process custody permits', 'manage secret', 'independent scheduling grants') where plain language would carry the same meaning in fewer words.

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, open-world mutation with no output schema, the description covers the important behavioral facts (notification/cancellation, idempotent retry, recovery limits). It is still incomplete on what the 'scheduling grants' are, how failure is surfaced, and how this tool relates to the preview and cancel/reschedule siblings.

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% with three required params, so the description carries the burden. It loosely maps the three fields to 'preview', 'hash' and 'confirmation reference' as distinct artifacts that must match the original preview, which clarifies their joint role, but it adds no format, validity or constraint detail beyond what the property names already convey.

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 is 'Commit' and the object is a 'create preview', which implies finalizing a booking, but the phrasing is ceremony-laden rather than plainly naming the resource ('book a meeting'/'create a booking' never appears). An agent can infer it is the commit step of a two-phase scheduling flow but must decode jargon ('owner-confirmed create preview', 'independent scheduling grants') to be sure.

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 implies this is the commit that follows a preview step and gives one concrete scenario ('reuse the same preview, hash and confirmation reference after uncertainty'), which is real usage guidance. However, it never names the corresponding preview tool (e.g. preview_scheduling_action) or distinguishes itself from siblings like cancel_booking/reschedule_booking, so routing is inferred rather than stated.

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