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

Annotations already declare destructive and idempotent behavior)Skip. The description adds that the action requires 'explicit approval metadata' and a 'matching idempotency key', which are meaningful behavioral guardrails beyond the annotations. It also clarifies this is the bind step, not a fresh transition.

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 sentence, front-loaded with the verb and resource, and it immediately conveys the key precondition ('already-previewed') and the two essential concepts (approval metadata, idempotency key). No wasted 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?

The tool is complex (nested binding object, 5 required fields, no output schema, no parameter descriptions). The description does not explain how to obtain the binding values or what the response looks like. An agent cannot reliably call this tool without additional documentation or sibling tool descriptions.

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 carries the burden of explaining parameters. It mentions 'approval metadata' and 'idempotency key' but fails to explain the binding object fields (preview_hash, approved_action_key, etc.) or their relationship to a preview. This leaves the agent unable to correctly populate the 7 parameters.

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 clearly states a specific verb ('Bind') and resource ('application transition'), and scopes it to 'already-previewed' transitions. This distinguishes it from preview tools and from the direct transition tool, even without naming siblings.

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 tool is used after a preview has occurred ('already-previewed'), but it does not explicitly instruct the agent to call the preview tool first, nor does it mention when to use this instead of the direct transition tool. Context is present but exclusions are not stated.

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