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

Annotations already declare readOnlyHint=false, and the description adds that this is scheduled outreach through configured channels. It does not explain delivery timing, failure behavior, or downstream effects, but the 'schedule review request outreach' phrasing provides useful behavior context 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 informative sentence is concise and front-loaded, but the description begins with a redundant 'Create Ask' line that duplicates the tool name/title. It is short, but not every sentence earns its place.

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?

With a rich input schema and an output schema, the description is adequate for basic invocation of a schedule-outreach action. However, it lacks explicit usage guidance, prerequisites for configured channels, and behavioral details such as whether messages are sent immediately or queued.

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 100%, so the schema already documents all parameters in detail. The description only mentions channels, adding little semantic value beyond what the schema provides for email, phone, asked_at, or reminders_count.

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 states a clear action and resource: it schedules review request outreach and names the delivery channels (email/SMS). It does not explicitly distinguish createAsk from siblings like createReview or cancelCustomerUnsentMessages, but 'review request outreach' narrows the meaning enough to avoid major ambiguity.

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?

No when-to-use guidance, exclusions, or alternative tool references are provided. The only implied usage is scheduling review outreach, which is not enough for an agent to confidently choose this over sibling tools such as createReview or createCustomer.

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