B3.1/5.0
Behavior3/5

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

No annotations exist, so the description carries the burden. It does add one meaningful behavioral fact: results come from the *running host's loaded* presets rather than on-disk profiles, which is a real distinction from profiles_list. However, it says nothing about read-only safety, pagination behavior, or how the default limit of 100 affects results.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with no filler. The resource and host scope arrive immediately, which is exactly what an agent scanning for a list tool needs.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

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. Still, for a paginated, filtered listing with four undocumented parameters and no annotations, the description should say something about the `kind` value domain and pagination defaults to be call-ready.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% and the description explains none of the four parameters. The mention of 'process, printer or filament' hints at the accepted values for `kind`, but `limit`, `offset`, and `query` (a substring filter versus exact match?) are entirely undocumented in both places.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (list) and resource (loaded process/printer/filament presets) scoped to the running host, which is more precise than the sibling name alone suggests. It does not differentiate itself from close siblings like host_preset_read or profiles_list, so an agent must infer the boundary.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance, no mention of when to prefer host_preset_read for full preset contents, and no note on how this relates to profiles_list. The agent gets a purpose but no routing logic among the many preset/profile/settings siblings.

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