Behavior2/5

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. It only lists operations without any details on side effects (e.g., data loss on delete), authentication needs, rate limits, or other behavioral traits. The description is insufficient for safe invocation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single short sentence that efficiently conveys the tool's purpose and allowed operations. It is concise, though it could be structured to front-load the most critical behavioral information (e.g., side effects of delete).

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 8 parameters, no output schema, and no annotations, the description is too minimal. It does not explain return values, parameter requirements per action (e.g., name required for create/delete but not list), or operational constraints. Important context is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is high (88%). The description does not add parameter-specific meaning beyond what the schema already provides, such as dependencies between parameters and the action field. It relies entirely on the schema for parameter semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool manages Ceph pools and explicitly lists the supported operations: list, create, update, delete. This provides a specific verb and resource, and no sibling tool duplicates this exact purpose, ensuring easy differentiation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the tool is for managing Ceph pools via the listed actions, but it does not explicitly state when to use it vs. alternatives (e.g., general Ceph management tools like proxmox_ceph). No usage scenarios, prerequisites, or exclusions are mentioned.

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