v0.1.6Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears the full burden of disclosing operational behavior. It does not explain whether the volume must be attached, whether trimming is disruptive, or what side effects occur; 'trim the filesystem' leaves these details to inference.
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 very brief, but the first sentence merely restates the title and the second is only a link. The wording is concise but not substantive; the limited space could have been better used for operational details.
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 no annotations, no output schema, and a one-sentence description plus a link, the definition omits crucial context for a filesystem-trim operation. The external link may help a human, but an AI agent needs the key information inline.
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 single parameter 'name' has no schema description (0% coverage), and the tool description does not define it. An agent might infer it refers to the volume name from the context, but the description fails to explicitly state the parameter's meaning, format, or requirements.
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 states a specific verb and resource, 'Trim the filesystem on a volume,' which clearly identifies the operation. However, this essentially restates the tool's title and provides no differentiation from sibling volume-management tools like volume_attach or volume_snapshot_purge.
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?
There is no guidance on when to use this tool versus alternatives, nor any mention of preconditions, exclusions, or when trimming is appropriate. The only extra is an external documentation link, which does not substitute for explicit usage instructions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
