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

Annotations already declare this is non-read-only, destructive, and idempotent, so the description does not need to restate those. It adds useful context that approval metadata and a matching idempotency key are required to execute the conversion. It does not, however, explain what destructive effect the conversion has, such as whether the prospect is removed or archived.

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 a single sentence with no filler and is appropriately front-loaded with the main action. It is concise, though its brevity comes at the cost of explaining important semantics like what 'bind' means and how the binding object is obtained.

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?

This is a complex tool with seven parameters, a nested required binding object, no output schema, and zero schema descriptions. The description does not explain the preview-to-bind workflow, how approval metadata is obtained, failure conditions, or the post-conversion state. It is not complete enough for an agent to understand the operation's place in the broader convert flow.

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 for the absence of parameter documentation. It only vaguely references 'approval metadata' and 'matching idempotency key', which gestures at the binding object and idempotency_key relationship, but it does not explain the required nested fields, note, source_label, or request_id. An agent would struggle to construct a valid request from this description alone.

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 and resource: 'Bind an approved prospect conversion preview', and the title clarifies the outcome is converting a prospect into an application. This distinguishes it as the confirm/execute counterpart to the preview tool, though 'bind' alone is somewhat jargon-heavy and the description does not explicitly say the prospect becomes an application.

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 phrase 'approved prospect conversion preview' implies this is the second step after a preview has been generated, and 'matching idempotency key' implies a required pairing. However, the description never explicitly names the preview alternative or states when not to use this tool, so the usage guidance is only implied rather than direct.

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