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

Annotations already declare readOnlyHint=true, openWorldHint=true and destructiveHint=false, so the safety profile is covered. The description adds the concrete endpoint path GET /v1/accounts/{accountId}/autoresponders, which is useful context, but says nothing about pagination, result limits, or whether it reads across all sub-accounts.

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?

Two short sentences, front-loaded with what the resource is, with zero filler. The trailing endpoint path is slightly redundant but still informative, and nothing is buried.

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 zero-parameter read tool with annotations covering safety, the definition is close to sufficient, but with no output schema it still never hints at what an autoresponder record contains or how many are returned. A single clause on return shape would close the gap.

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, and the schema documents that fully, so there is nothing for the description to compensate for. Baseline 4 applies; the endpoint fragment at least shows the accountId is injected in the path rather than supplied by the caller.

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 identifies the resource ('autoresponders configured on the account') and parenthetically defines it as 'automatic replies', which a reader can map to a listing operation. It lacks an explicit verb, but the name supplies 'list' and the resource scope is unambiguous against siblings like list_templates or list_webhooks.

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 guidance on when to call this versus related tools (e.g., sakari_get_account for account-level config) and no mention of prerequisites such as needing an accountId or permission scope. The agent must infer usage entirely from the name.

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