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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds value by explaining what an automation is and what each listed item contains, but says nothing about volume, pagination, or ordering of results.

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 text is short but written as sentence fragments with an odd ordering; the core payload (scope, returned fields) is not cleanly front-loaded. The definitional sentence about what an automation does is mild filler for an agent that already knows the domain.

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 single-parameter read-only list tool with no output schema, the description usefully enumerates the returned fields, which is the main thing missing from structured data. Only result volume/pagination behavior is left unaddressed.

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?

There is one parameter with 100% schema coverage, and the schema already explains that `site` must match a name from `list_sites`. The description only restates "named in site," adding no syntax, format, or constraint beyond the schema, so the baseline of 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 definition names the resource (automations), the scope (one site, named in `site`), and the returned fields (trigger, conditions, on/off state). It also distinguishes itself from `get_automation`, which returns steps and members. The fragmented opening sentence ("On one site of the account, named in site.") is awkward but still readable.

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 implies the split with `get_automation` (that tool gives steps and members), so an agent can infer this is the overview call. However, there is no explicit when-to-use or when-not-to-use statement, and no prerequisite/permission guidance.

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