spoolman_get_filament

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

No annotations are provided, so the description carries full burden for behavioral disclosure. The description merely restates the tool's name and adds 'by its ID', providing no additional context such as read-only safety, error behavior (e.g., what happens if the ID doesn't exist), or response format. This is a significant gap for a tool with no annotation support.

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, front-loaded with the action and resource. Every word is necessary; there is zero fluff or redundancy.

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?

Given the simplicity (one parameter, no output schema), the description is minimally adequate but not complete. It lacks any mention of return value structure or failure modes. Since no output schema exists, the description should at least hint at what the response contains, but it only says 'get a single filament' which is terse. It is not genuinely helpful beyond the bare minimum.

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 100% — the schema already fully documents the only parameter 'id' with its type, description, and exclusiveMinimum. The tool description adds nothing beyond the schema, so the baseline 3 is appropriate.

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 'Get a single filament by its ID' with a specific verb and resource. It distinguishes from sibling tools like list_filaments, create_filament, and delete_filament by emphasizing 'single' and the use of an ID.

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?

Usage is implied through the phrasing 'by its ID' — an agent can infer this is for retrieving one specific filament when the ID is known. However, there is no explicit guidance on when to prefer this over list_filaments or other alternatives, so it only meets the implied standard.

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