volume-set

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

Annotations are absent, so the description must explain behavioral aspects. It mentions 'writable' but doesn't describe consequences of setting a property (e.g., irreversible changes, potential errors on invalid paths, or need for context). No mention of validation or side effects.

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 sentence, clear and to the point, with no unnecessary words. It's appropriately sized for a simple setter.

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?

For a tool that mutates volume properties, the description lacks context about error handling, what happens if the property is invalid, or the need for an existing volume. It also doesn't mention that it only sets one property at a time, which is implied but not explicit. Given the tool's simplicity, a slightly more detailed description would improve completeness.

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%, but the description adds no parameter details. It leaves the 'value' format as a JSON string, but doesn't explain that it must be valid JSON or how to construct a property path beyond the schema's example. The schema titles already provide examples, but the description doesn't enhance them.

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 (Set) and the target (volume data-block or nested settings object), and specifies 'one writable RNA property' which distinguishes it from reporting or listing tools. However, it doesn't explicitly differentiate from sibling setters like 'physics-set' but the resource is clear.

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?

No guidance on when to use this tool over alternatives like volume-report, volume-import, or other setters. It doesn't mention that for multiple properties one might need multiple calls or that it's only for volumes.

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