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

With no annotations, the description carries the full burden. It does disclose two non-obvious behaviors: this is a mutation ('Commit') and it enforces an optimistic-concurrency check ('if nothing changed since'). It omits what happens on a failed precondition, whether the operation is idempotent/retryable, and what the confirmation_id represents beyond the implied link to the preview.

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 front-loaded sentence with zero filler — the action comes first and the precondition second. It is tight to the point of under-specification, but that gap is better attributed to completeness than to verbosity.

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 the concurrency precondition is stated. What is missing is lifecycle context: in a sibling landscape full of preview/commit/cancel triples, the description does not say this must follow the preview tool, nor how it differs from nws_app_commit_import, and leaves the sole required parameter unexplained.

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% on the single parameter, confirmation_id. The description only implicitly ties it to the preview step via the word 'previewed'; it never says the value comes from the preview response, whether it expires, or how a mismatch is reported. The adjective 'previewed' is the only bridge the agent gets.

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 (commit) and a specific resource (a previewed NWP app reservation import), so the agent knows this finalizes a pending import rather than starting one. It does not explicitly name its siblings (preview_app_reservation_import, cancel_app_reservation_import, nws_app_commit_import), so the distinction is implied by the word 'previewed' rather than stated.

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?

'if nothing changed since' gives a real precondition, implying this must be called after the preview step and only when the underlying data is unchanged — useful guidance that is not in the schema. However, it never states what to do when the condition fails (re-preview? cancel?) or names the alternative tools, so the when-not path is left to inference.

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