rbd_snapshot_create

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

With no annotations, the description carries the full burden. It discloses that the operation is a write with low risk ('[WRITE][risk=low]') and is reversible. However, it does not describe side effects, state requirements, or error conditions, leaving some behavioral gaps.

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 extremely concise: one purpose sentence, one reversibility note, and a lean parameter list. Every sentence adds value with no redundancy, and the structure front-loads the core action.

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 no annotations or output schema, the description provides essential purpose and parameter semantics but lacks prerequisites, return value, and error handling. It is partially complete for an agent familiar with Ceph but could be more thorough.

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 has 0% description coverage, so the description must explain params. It provides brief but clear meanings for all four parameters (e.g., 'Pool the image lives in' for pool_name), adding value beyond the schema titles. It could include validation constraints or examples but is adequate.

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 ('Snapshot') and the resource ('RBD image'), making the purpose obvious. However, it does not explicitly differentiate from sibling tools like rbd_snapshot_delete or rbd_image_create, though the verb is specific enough for an agent to infer.

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 only notes reversibility ('Reversible → delete the snapshot'), which hints at when to use but does not provide explicit guidance on when to or when not to use this tool versus alternatives (e.g., rbd_snapshot_delete). No context about prerequisites or scenarios is given.

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