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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description usefully adds that scope is limited to User Library presets, but says nothing about how the query affects results, ordering, or result size.

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?

One short sentence with the key resource and location front-loaded, plus a helpful example. It is efficient, though the space spent on the vocal-chain example could have documented the query parameter instead.

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?

An output schema exists, so return values need not be described, and a read-only list tool is simple. Still, with a single undocumented parameter and no guidance on the competing preset-listing siblings, the definition is only minimally complete.

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 0% for the single "query" parameter, and the description never mentions it. It is unclear whether query is a substring filter, a fuzzy match, or ignored when empty, so the description fails to compensate for the schema gap.

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 gives a specific verb ("List") and resource ("device/rack presets (.adg/.adv)") plus the storage location (User Library), and the example clarifies the concept of a saved chain template. It does not name a sibling such as list_plugins or get_plugin_presets to differentiate itself, so it stops short of a 5.

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 "saved in the User Library" implies this is for user-created presets rather than factory content, which is some usage signal. However, there is no explicit statement of when to choose this over list_plugins, get_plugin_presets, or search_browser, all of which appear in the sibling list and could plausibly compete.

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