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

Annotations already declare destructive, idempotent, and open-world behavior. The description adds useful context beyond them: it can notify the recipient including cancellation, retries should reuse the same preview/hash/confirmation reference, and missing private process custody permits receipt recovery but not a new dispatch.

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 description is short and front-loads the main commitment action before side effects and retry guidance. It is dense with jargon and could be clearer, but no sentence is purely redundant.

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 three required parameters and no output schema, the description leaves important gaps: it does not explain parameter distinctions, prerequisites beyond 'owner-confirmed preview,' alternatives, or return behavior. Some behavioral context is present, but the definition is not sufficient on its own.

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 description must compensate. It maps the required parameters to 'preview,' 'hash,' and 'confirmation reference' and says to reuse them after uncertainty, but it does not explain each parameter's distinct role or constraints beyond the schema's format fields.

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 action ('Commit') and resource ('reschedule preview'), making the core operation clear. It does not explicitly distinguish the tool from sibling preview or cancellation tools, and the phrase 'both independent scheduling grants' adds jargon without clarifying scope.

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 implies usage after an owner-confirmed reschedule preview exists and gives a retry rule for uncertainty, but never names alternatives such as preview_scheduling_action or cancel_booking. The when-to-use context is inferable rather than explicit.

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