spoolman_update_filament

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

The description discloses the key behavior of partial updates (fields not provided remain unchanged). However, with no annotations, it does not address error handling, required permissions, or response format, leaving some behavioral aspects undisclosed.

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 two short sentences, front-loaded with the core purpose and a critical usage rule. There is no wasted verbiage.

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?

While the description is brief, it covers the essential update semantics, and the schema fully documents all parameters. The lack of an output schema means return values aren't described, but this is a minor gap for a straightforward update tool.

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?

The schema already provides full descriptions for all 14 parameters (100% coverage). The description adds valuable semantic guidance beyond the schema by clarifying that only the fields to change should be provided, which is essential for correct invocation.

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 action: 'Update an existing filament by ID.' It specifies the resource (filament), the operation (update), and the identifier (ID), distinguishing it from sibling tools like create or delete.

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 instruction 'Only provide the fields you want to change' provides clear guidance on partial update semantics. It implies usage context for modifying an existing filament without specifying exclusions or alternatives, but the context is unambiguous.

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