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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description usefully explains what class of objects is returned (comment-to-DM and story-reply automations), but says nothing about scope, pagination, or ordering for this list operation.

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?

A single tight sentence with no filler, and the defining trait ('without the flow editor') comes first. It is a noun phrase rather than a verb-led statement, so the action is only implied by the title.

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 list tool with annotations covering safety and no output schema, the description does enough by characterizing the resource. Gaps are minor: no statement of account/workspace scope or result volume.

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 schema coverage is 100%, so the baseline of 4 applies. There is no parameter detail the description could add or omit.

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 names the resource precisely — 'the simple automations built without the flow editor' — and enumerates the two concrete behaviors (comment keyword triggers a DM, story reply triggers a bot answer). It implicitly distinguishes this from flow-editor automations, but never states the verb 'list' or names the contrasting sibling explicitly.

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?

The phrase 'built without the flow editor' hints at the boundary with list_automations, but no when-to-use condition or alternative is named outright. An agent must infer that list_automations is the counterpart for flow-editor automations.

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