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

With annotations present, the description adds substantial context the annotations do not carry: the page is private, the version is immutable, one review credit is consumed (a cost/quota signal), and the returned link must be conveyed out-of-band. The idempotency_key retry note is consistent with idempotentHint=false rather than contradicting it. It does not restate the non-destructive profile that annotations already cover.

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?

Four short sentences, each carrying a distinct fact (purpose, artifact, delivery of link, cost/retries) with minimal waste. It is front-loaded on the outcome and closes with the operational caveat, though the opening sentence is slightly indirect for a creation tool.

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 6-parameter, non-destructive mutation tool with an output schema and annotations, the description covers the full workflow: create, immutable snapshot, private link, out-of-band delivery, credit cost, and retry safety. Return values are correctly left to the output schema, though credit/quota preconditions could be spelled out more explicitly.

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 83%, so the schema already documents title, text, choices, image_urls, expires_in_seconds, and idempotency_key in detail. The description only reinforces idempotency_key for retries; it adds no new semantics about choices vs approval flows or image constraints beyond what the schema states, so the 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 description states the outcome (get feedback or a selection from a person) and the resource created (a private page for an immutable version of text or images), so an agent can tell this is a review-creation tool distinct from get_review/cancel_review. However the first sentence leads with the user goal rather than the action, so the verb 'create' is implicit rather than explicit.

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 gives useful operating guidance ('send the returned link through your own communication channel', 'use idempotency_key for retries'), which is real when-to-do-what context. But it never states when to choose this over siblings like get_review, claim_task, or complete_task, nor any prerequisite (e.g. needing a credit balance) beyond the cost note.

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