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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety is covered without description help. The description adds genuine behavioral context beyond that: a state-dependent branch (`answering` false = agent not deployed) with a required next action. It doesn't discuss freshness or whether the link is stable/revocable, which keeps it off a 5.

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 purpose is front-loaded, but the body is a long, clause-chained sentence that mixes return-value documentation (`url`, `tellUser`, `answering`, `installSnippet`) with sales-style instructions ('a bio, an email signature, order emails, a help center'). Since an output schema exists, the field-by-field enumeration is partly redundant, and the installSnippet explanation arrives after the workflow advice rather than alongside its counterpart.

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 an output schema present and zero parameters, the remaining burden is workflow context, and the description supplies it: when to offer the link, the deploy prerequisite branch, and what the second artifact is for. An agent could act on this without consulting a sibling or guessing at preconditions.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. The description instead spends its words on output fields, which is not a parameter concern.

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?

States a concrete verb and resource ('Get the workspace's Aide chat page') and immediately defines it as 'a public link (`url`) where anyone chats with Aide.' It also separates that from the `installSnippet` artifact, so the agent can distinguish the two outputs. It stops short of a clean one-line definition because the purpose statement is intertwined with workflow prescriptions.

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?

Gives explicit sequencing: 'Offer it right after test_agent,' then handle `answering` false by asking for the OK and calling deploy_agent in the same turn. It also names the follow-up (installSnippet) as 'second,' so both ordering and the exclusion of the website path from the first step are spelled out.

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