u1_list_profiles

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

No annotations are present, so the description carries the burden. It discloses that default returns names and details=true returns full metadata, which is useful behavioral context. However, it does not mention read-only status, filtering semantics, or output format, leaving significant unknowns.

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 description is a single concise sentence that front-loads the core action and mode. It is efficient and free of unnecessary words, though it sacrifices some parameter information for brevity.

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?

With 4 optional parameters, no output schema, and no annotations, the description is insufficient. It does not explain the role of the filter parameters, what 'full metadata' entails, or the structure of the response. An agent would need to guess or inspect further to call this tool correctly.

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 coverage is 0%, so the description must explain parameters. It only clarifies 'details' but leaves nozzle, material, and layer_height unexplained. These likely serve as filters, but without guidance, agents may misuse them. The description adds minimal value beyond the schema for three of four parameters.

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 clearly states the verb 'list' and the resource 'discovered Snapmaker U1 profile names', and distinguishes it from siblings like u1_get_profile by pluralizing 'profiles'. It also introduces a mode (default vs details) that differentiates behavior.

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 description implies it's used for listing profiles, but does not explicitly state when to use it versus alternatives like u1_get_profile or u1_profile_source_chain. No exclusionary guidance is given, leaving the agent to infer context from the verb 'list'.

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