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

Annotations cover the safety profile (readOnlyHint=false, non-idempotent, but non-destructive), and the description adds that delivery goes through 'configured' channels, hinting at a setup prerequisite. It does not disclose that real messages are dispatched, whether sending is rate-limited, or that reminders_count triggers follow-up sends — meaningful gaps for an outward-facing action.

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 substantive sentence is tight and front-loaded, but it is preceded by the disconnected 'Create Ask' fragment, which reads as leftover artifact text and dilutes the opening.

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 not be described, and the 100%-covered schema carries parameter detail. Combined with annotations declaring the write/open-world profile, the description is sufficient for an agent to call this correctly.

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 email, phone, asked_at, channels, and reminders_count in detail. The description's channel mention reinforces the required enum parameter but adds no syntax or format detail beyond the schema; baseline 3 applies.

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 second sentence gives a specific verb (schedule) and resource (review request outreach) with the delivery mechanism (email or SMS). It distinguishes the tool from createReview, which records a review, though the leading 'Create Ask' fragment is stray noise that adds nothing.

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?

There is no statement of when to use this tool versus createReview or the other review-related siblings, and no mention of prerequisites such as channels needing to be configured beforehand. Usage is only implied by the word 'outreach'.

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